I already have a clean SwiftUI front-end for an OpenVPN app; the missing piece is the actual tunnel. Your role is to complete the Packet Tunnel Provider, wire it into the UI, and make the connection lifecycle rock-solid. What needs to happen • Build or finish the PacketTunnelProvider target, using the official OpenVPN library, so the app can connect, disconnect, and reconnect in the background without drops or hangs. • Surface real-time session stats (data in/out, duration, live throughput) to the SwiftUI views I’ve prepared. • Resolve the current issues with automatic reconnect after sleep/airplane-mode and cleanly handle edge-cases such as failed handshakes or revoked certificates. • Test everything on a physical iPhone; the simulator won’t cut it b...

I am seeking a Cisco SD-WAN expert to resolve a control plane reachability issue. Currently, my controllers (vManage, vBond, and vSmart) are hosted on prem behind a Unifi Gateway with port forwarding. After changing the vBond IP to a Public IP and implementing port forwarding, the controllers are experiencing the following issues: Control Plane Flapping: vSmart and vManage are constantly losing connections to the vBond (Logs show "Control No Active vBond" and "OMP Vsmart Down"). Application Failures: vSmart is periodically throwing Error: application communication failure when running CLI commands. NAT Loopback/Hairpinning: The controllers are in the same subnet (172.16.5.x) but are configured to point to the vBond via its Public IP, causing DTLS/TLS stability issues. P...

My team runs all of our workloads on EC2 and S3 and I want a seasoned AWS engineer to give our current set-up a health check, shore up security, and boost overall performance. The immediate priorities are: • Configuration review – walk through every EC2 instance, S3 bucket, IAM policy and networking rule, calling out weaknesses in security settings and opportunities for performance optimization. • Backup database build – spin up a separate RDS instance that every developer can connect to, then put a clear, manual promotion workflow in place so we can push approved data to production only when we decide. • Hands-on knowledge transfer – my staff are beginners, so I need short, practical training sessions that show them exactly how to navigate the AWS con...

I need a fresh installation of Windows Server 2019 Standard with 2 VM's on bare-metal hardware(current running WinSrv 2012 Std) and need an expert hand to assist me remotely with setup and virtualization layer to spin up two guest machines for web hosting. Each VM must be configured so I can quickly use or back-up disks from or in qcow, qcow2 or raw image format without compromising security. Here is what the engagement looks like: — Prepare the host: enable and fine-tune the virtualization role, apply best-practice updates, and confirm networking is ready for public-facing HTTP/HTTPS traffic. — Create two VMs: allocate sensible CPU/RAM, attach storage that supports qcow/qcow2/raw, install the preferred Linux as guest OS, with a imported image to prove everything work...

I need an experienced Windows infrastructure engineer available 40 hours a week, Monday-to-Friday, 9 am–5 pm (my local time), for the next three to six months. Your day-to-day priority is hands-on maintenance and support: keeping our Hyper-V virtualisation platform, Active Directory, and Office 365 environment fully patched, optimised, and trouble-free while always thinking “security first” in line with a Zero-Trust mindset. Alongside the routine work you will also help me formalise and document best-practice configuration “by the book”, carry out small-to-medium migrations between tenants or hosts, and ensure Veeam backups are running cleanly. Regular system updates, performance monitoring, and swift issue troubleshooting are expected without prompting&mdash...

I run a Windows-based environment that relies heavily on Microsoft 365—primarily Outlook, Teams, and OneDrive—and several of our users are blocked by a combination of email login failures, nagging Office activation errors, and an unreliable VPN. On top of that, day-to-day desktop tickets and noticeable slow-downs on a few machines need prompt attention. What I need is an experienced L2 engineer who can jump in remotely, pinpoint the root causes, and leave everything running smoothly without disrupting the team’s workflow. You should be comfortable working in a mixed Windows 10/11 setup, familiar with Azure AD, Intune or Group Policy for sign-in and licensing sync, and confident using tools such as PowerShell, Exchange Admin Center, and standard remote-support platforms. ...

We are looking for a skilled network engineer to configure one Cisco FPR-1120 firewall. There is no internet connection config needed for this firewall as it is local network access only. I’ll provide anydesk and remote console access and a maintenance window when we’re ready. - Interfaces and IP address allocation ( Internal, External IPs must be on same scheme, like for inside network IPs should be to and outside network IPs should be to ). ( We do NOT different Internal, External IPs scheme, like for inside network IPs to and outside network IPs to ).

I’m setting up an EVE-NG environment dedicated to realistic enterprise-grade network simulation. The goal is to emulate the mix of routers and switches you would normally find in a corporate core-to-edge design, then use that sandbox for future testing and skill-building. Here’s what I need from you: • Deploy or validate the EVE-NG installation (community or PRO, whichever you recommend for this scope) on my virtualisation platform. • Import the relevant router and switch images, verify they boot cleanly, and apply any optimisation tweaks so the lab runs smoothly even under load. • Build an initial enterprise topology that includes core, distribution and access layers, complete with basic IP addressing and connectivity tests so I can hit the ground running....

I’m looking for a reliable partner who can take full ownership of my existing infrastructure. The work centres on two areas—our network and our on-prem/virtual servers—and I need ongoing support rather than a one-off fix. Network scope • Continuous monitoring with clear reporting dashboards • Routine maintenance that prevents downtime and resolves issues before users notice • Strict security management to keep threats out and ensure compliance • Performance optimisation so traffic flows smoothly even during peak loads Server scope • Proactive monitoring and regular health checks • Security hardening, patching, and incident response You’ll have access to my current topology diagrams, device inventories, and server imag...

Timing is critical, so please only engage if you’re available to tackle this immediately and can wrap it up inside two hours. I need my static website moved from its current DigitalOcean droplet to a freshly created, smaller one—today, within the next couple of hours. I already generated the new droplet and have full SSH access to both machines, so keys and credentials are ready for you as soon as we start. The site went offline after an SSL error, and a quick check showed Nginx and a few other packages are out-of-date. During the transfer I want the stack brought up to current stable versions so we don’t hit the same issue again. Once everything is in place the domain should resolve cleanly over HTTPS with a valid certificate (Let’s Encrypt is fine). Deliverabl...

I need a technician for future issues like this: I run a mixed Windows 10, Windows 11, and Windows Server environment and critical domain issues are disrupting daily work. Top priority is restoring domain stability—users can’t authenticate, some PCs lose contact with the domain controllers, and several Group Policies refuse to apply. Once the domain is healthy, I also need help with a stubborn boot-loop on one workstation, fine-tuning Windows Defender Firewall rules, and checking a handful of other advanced Windows quirks that have crept in. You’ll have full remote access (VPN + RDP) and I’ll be available for live testing or quick reboots. Typical tools in play here are Active Directory DS, DNS, GPMC, Event Viewer, PowerShell, and Sysinternals; feel free to brin...

I already have a complete n8n workflow built and running on n8n cloud; now I need it hosted permanently on a local Windows server that I control. Your job is to install n8n on that machine, migrate my existing workflow, and make sure everything runs reliably every time the server reboots. You’ll be working with Windows Server — no cloud or dedicated hosting, just this on-prem setup. Deliverables I expect: • n8n installed and configured as a Windows service (or comparable solution) so it starts automatically • My exported workflow imported and confirmed working end-to-end • Clear notes on any environment variables, ports, or dependencies you touch I can provide remote access (RDP or preferred tool) and the workflow export file as soon as we start. If thi...

Our production network is showing its age: users complain about frequent disconnections, sluggish throughput, and I have already spotted a few worrying security gaps. I need an experienced network engineer to jump in, isolate the root causes, and leave the entire environment stable and secure. Scope The job covers every layer that might be contributing to these symptoms—routers, switches, firewalls / security appliances, and even the cabling runs between closets. You’ll be expected to inspect configurations (Cisco IOS, Juniper, FortiOS or similar), test physical links, run packet captures with Wireshark or equivalent, and tighten any loose security rules you uncover. Deliverables • Clear root-cause report for each problem found • Corrected or optimised device ...

I’m looking for a seasoned Cloud & DevOps engineer who can be on-call for two scheduled hours each weekday and walk me through issues live over a screen-share. You will not log in to the servers yourself; instead, you’ll act as a real-time coach while I operate the keyboard. Day-to-day you’ll help me: deploy and tweak Kubernetes workloads on AWS, untangle CI/CD flows built around ArgoCD and GitOps, and sanity-check everything from Prometheus-Grafana dashboards to Splunk logs and CloudZero cost insights. When something breaks—be it a Kafka topic, a DynamoDB table, or our Go microservices—you’ll jump on a video call, see exactly what I see, and advise on the quickest, safest fix. The commitment is strictly part-time (about 10 hours a week), yet r...

I need an experienced network engineer for a single full-day visit to my client’s facility. Your primary goal is to rack, stack, power up, cable, and provide console access for new routers, switches, and firewalls exactly as shown in our network diagrams. My remote team will handle all configuration after you confirm console reachability, so no advanced CLI work is required on site. You must arrive with your own standard toolkit—screwdrivers, cage nuts, patch cables, console lead, cable tester, and a laptop able to run console software—so you can work independently without borrowing equipment. While the network gear is booting, I’ll also rely on you for light hands-on support with user devices: verifying desktop or laptop imaging, reseating or swapping simple co...

Each week I pull together every Alibaba purchase order so my bookkeeper can reconcile inventory costs against our Amazon FBA and Australian marketplace sales. I’m looking for someone who can step in and run the reports and receipt-gathering process for me. Your core focus will be reports and receipts management, specifically purchase order reports sourced from my Alibaba account, but also you wil help in Amazon accounts around report collection - this means potentially you may need to validate ID with amazon as a support role in our account. You’ll log in, export the relevant order data, match it with supplier invoices or screen-captured receipts, and drop everything into a neatly organised Google Drive folder that mirrors the way our books are structured. Please tell me:...

I recently migrated my personal blog to a new server and it now fails to load properly. The files and database were copied over without issue, yet the front end either times out or shows a generic error page, so something in the new environment isn’t lining up. Your task is to dive in, trace the root cause, and bring the blog back online exactly as it was before the move. I can provide full SSH/FTP access, control-panel credentials, and any previous configuration files you might need. Deliverables: • Diagnose the failure (server logs, configuration, permissions, database connection—whatever proves relevant). • Apply the fix and confirm every page of the blog renders correctly. • Offer a brief summary of what went wrong and the steps taken so I have a refere...

I need Google Cloud Logging fully configured to ingest real-time syslog from both firewalls and routers on my network. The estate includes several firewall brands and models, all of which can point to a syslog target, so the solution must stay vendor-agnostic. Here is what I’m after: • Stand-up or fine-tune a log forwarder (Fluent Bit, rsyslog, or any proven alternative you prefer) that listens locally, receives the events, and reliably forwards them into Google Cloud Logging. • Lock the listener down so it will only accept traffic from a strict IP whitelist—this is the sole authentication method required right now. • Validate that messages from at least one firewall and one router reach the correct Log bucket with original timestamps intact and the proper r...

I have a fresh Linux-based VPS that’s ready for action, but I want to make sure it’s set up the right way from day one. The immediate goals are to deploy a couple of small web apps and lock the server down so I can sleep at night knowing nothing is exposed. Here’s what I need from you, in close collaboration with me (I’ll be on the call or chat while you work): • Clean, repeatable deployment using Dokploy or a similar tool you’re comfortable with. • Hardened server configuration: SSH key-only access, minimal open ports, firewall rules, fail2ban, regular package updates. • SSL/TLS certificates installed and auto-renewing. • Basic monitoring/logging in place so I can spot issues early. • Simple, documented rollback procedure in...

I’m expanding a GoHighLevel-based business with sites and need a dedicated partner who can own both the SEO roadmap and the everyday admin work inside GHL. The immediate mission is to push our pages up the rankings. My biggest pain point is on-page SEO, and phone registrations so you’ll start by reviewing content, keywords, meta-tags and internal links across the whole site builder. From there, we’ll map new keyword clusters, adjust page structures for better crawlability, and monitor results through GHL analytics and Search Console & SE Ranking. Content creation is part of the job. You’ll draft and publish fresh blog posts, polish product and service descriptions, and fine-tune landing pages so every piece lines up with our target phrases. I move fast, so th...

I currently have SOLR 4.4.0 running on a DigitalOcean droplet.I want to create a new droplet and install the latest SOLR 9.10. The existing set up should then be migrated across so that it runs on will be given ssh root access to both existing and new to enable this to be actioned.

Tengo un sistema web () que funciona bien pero es antiguo escrito en PHP que trabaja con MariaDB. Dispongo de todo el código fuente y del dump original superglass_com_ar.sql. Hoy necesito que funcione de forma estable en mi entorno local con Docker Desktop para Windows. La tarea engloba cuatro frentes: • Crear desde cero la imagen y los contenedores (PHP + Apache/Nginx, MariaDB) y dejar todo orquestado en docker-compose. • Importar la base de datos, resolver los errores de autenticación y de gestión de permisos; ambos fallan por incompatibilidades con PHP moderno, en especial el uso de $_COOKIE sin comillas. • Limpiar archivos y dependencias que ya no se utilicen, dejando un repositorio más liviano y ordenado. • Generar documentaci&oa...
