From 58,453 reviews, clients rate our NoSQL Couch & Mongo Developers 4.9 out of 5 stars.The project covers two linked assets—a marketing website and an interactive web application—built as a single, cohesive code-base. Everything must be modern, fully responsive, and branded with a clean, intuitive UI/UX. Tech stack is already set: Angular on the frontend and a Node.js (Express) backend. Expect secure, stateless authentication (JWT or OAuth, whichever you judge best), role-based access, and a well-structured REST API that can later expand to GraphQL if needed. Data will live in either MySQL, PostgreSQL, or MongoDB; I’m open to whichever you recommend once requirements are refined. Core functionality • Public-facing pages for visitors • A logged-in web app with real-time notifications • Separate admin dashboard for user, content, and sett...
I’m preparing to launch a new initiative called “150.000koin” and need an experienced developer to help shape the technical side of the project from the ground up. Because the concept is still being finalized, I’m looking for guidance on which platform—web, mobile, or desktop—will best fit our eventual goals, as well as practical recommendations on architecture, security, and scalability. Key objectives: • Clarify and document the core functionality that will power 150.000koin. • Propose a technology stack that balances performance, cost, and ease of maintenance. • Deliver an initial, working prototype (basic interface plus back-end logic) that demonstrates main workflows such as user registration, asset tracking, and secure transact...
The goal is to design a future-proof relational backbone for a multi-channel retail platform, built natively on PostgreSQL. I already run an operational system, and its live transactional records will have to be migrated into the new structure without downtime. Everything else—users, inventory, orders—will start fresh. Core design expectations The operational schema should be fully normalised to 3NF and optimised from day one for high concurrency. Think table partitioning (range and list), well-chosen GIN and B-Tree indexes, plus JSONB columns where semi-structured flexibility makes sense. Triggers, constraints and stored procedures must enforce business logic consistently, so the application tier can stay lightweight. Analytics layer Alongside the OLTP schema I need a se...

I need a full-stack website that lets visitors request our “Cloud” home service and gives me a robust admin panel to run everything behind the scenes. The site has to be deployed on Microsoft Azure, so please structure the code and infrastructure (App Service, SQL/NoSQL, storage, CI/CD if you prefer) accordingly. Front-end • Modern, responsive landing page that explains the service and captures leads or direct bookings. • Clean contact/booking form with validation and confirmation emails. Admin panel requirements • User management (create, edit, suspend customers and staff). • Service booking management with status updates, filters, and search. • Analytics & reporting—at minimum daily/weekly booking counts and user stats, shown i...
I’ve put together the entire front-end of my React Native app and now I’m ready to connect it to a real backend. During a live Zoom or Microsoft Teams session I want to screen-share and work side-by-side while you guide me through each step. Supabase is the database service I’d like to use (or firebase), though I’m open to brief comparisons with Firebase if a decision point comes up. I have no prior backend experience, so you’ll need to walk me through project structure, environment variables, and deployment best practices. Whether the supporting server logic ends up in Node.js or another lightweight option, keep everything clear and beginner-friendly so I can maintain it afterward. We must cover: • Authentication setup – phone OTP authentication....

I’m building Curacare, a full-stack web app that lets people handle medical emergencies without scrambling for information. The heart of the platform is a seamless doctor-consultation flow, so the appointment-scheduling module has to feel effortless on both mobile and desktop. Alongside that core feature, users must be able to reach hospitals instantly through a dedicated “Contact Hospital” pathway—click-to-call, email, or any direct channel you suggest—surfaced within one tap from the dashboard. Speed and reliability matter more than bells and whistles: every interaction should load in under a second, and every piece of patient data must be encrypted at rest and in transit. Tech-stack choices are open, though I’m leaning toward a React front-end, ...

I want to turn my “my tool sharing” idea into a live web platform, handling everything from the first pixel of the interface to the last line of server code. At its heart the site needs one thing done perfectly: users must be able to list their tools and let others search for them quickly and intuitively. This first phase focuses only on that listing-and-search workflow. Reviews, ratings, booking calendars, and other extras can wait, so please build the architecture with clean separation of concerns to make those future add-ons painless. You are free to choose a modern stack—React, Vue, or vanilla JS for the front; Node, Django, Laravel, or a similar framework for the back—so long as the code is well-documented, componentised, and backed by a reliable database su...

I’m specifically looking for someone confident across frontend, backend, and database layers who can translate that depth into clear, structured technical training sessions. Your core mission is to design and deliver training that sharpens our developers’ practical skills. Expect to break down real project scenarios, walk through architectural decisions, explain code quality best practices, and answer ad-hoc questions as they come up. We work mostly with JavaScript/TypeScript, React, Node.js, and PostgreSQL, so fluency in these (or closely related stacks) will help you connect quickly with the team. Deliverables • A short training plan outlining top...
I’m searching for production-ready AI agents I can roll out across several verticals—specifically Healthcare, Real Estate, E-commerce, Blockchain, Crypto, and Social Media. Each solution must already be live somewhere so I can see it operating in real time before we move forward. The core requirements are straightforward: the agent needs to run in a browser, accept its own knowledge base or document set for context, and ship with source code plus clear documentation. I’m also expecting help getting the code stood up in a SaaS or on-prem environment. I’m flexible on architecture; whether you built it around OpenAI, Claude, Llama, FastAPI, Node.js, Pinecone, FAISS, or Weaviate doesn’t matter as long as it performs reliably at scale. To keep things simple, here...

I’m building a mobile-only app that needs a real-time text chat backend dedicated to one-on-one conversations. The goal is a lightweight, low-latency server that can authenticate users, deliver messages instantly, store chat history, and scale as the user base grows—all without the overhead of group or public room logic. I’m open to proven stacks such as Node.js with WebSocket/, Go with gRPC, or an equivalent solution that plays nicely with iOS and Android clients. End-to-end encryption, push-notification hooks (FCM / APNs), and a RESTful or GraphQL API for ancillary data are highly desirable. Deliverables • Production-ready server code with clear setup instructions • Secure user authentication and encrypted message transport • Message persistence (Mo...
I’m building a high-end real-estate lead engine that can capture, qualify, and route 150–200 fresh inquiries every week with a hard 99.5 % uptime target. Instead of a generic chatbot, the core of this MVP is a lightning-fast Custom Qualification UI written in React, backed by a Node.js API and a PostgreSQL (or comparable SQL) data store. What I need from you is end-to-end ownership of the stack: solution architecture, clean code, robust testing, and cloud deployment. The product must open the door for future add-ons such as a real-time analytics dashboard, but for this first milestone the focus is on: • Lead scoring system that assigns quality grades the moment data arrives • Automated lead routing that pushes hot prospects to the correct broker or CRM queue wit...

I need a sharp-eyed Flutter / Node.js troubleshooter to pinpoint and fix an intermittent signup failure in my mobile app. The OTP step completes successfully, yet many users (on both iOS and Android) hit a wall when the form tries to create the account. No explicit error is returned to the UI, but the account never appears in the database. Here is what I can share right away: • Front end: Flutter 3.x, using MSG91 for phone-based OTP. • Back end: Node.js (Express) REST API, MongoDB. • Flow: user enters phone → receives OTP → OTP verified → form posts profile details → failure occurs after the POST. What I need from you is a fast, reproducible diagnosis, a clean code fix (whether in Dart, the REST endpoint, or both), and a short hand-off note so my te...
The goal is to craft a complete web application from the ground up, pairing a React.js front end with a Node.js back end and shipping a functional MVP within a month. I already know I want React for the client interface, so the build should follow best-practice component architecture, modern hooks, and a clean, responsive layout. On the server side, Node.js (Express preferred) will power a RESTful API, handle authentication, and connect to a persistent data store—MongoDB or PostgreSQL, whichever you feel best suits the use case. To keep expectations crystal clear, here are the concrete deliverables: • Git repo initialized with meaningful commits, README, and .env sample • React UI coded, styled, and wired to the API (state management via hooks or Redux) • Node.js...
I’m planning a new web application and want one talented partner to take it from first commit to production. The stack is already set—React on the front end, Node.js (with Express or a comparable framework) driving the server side—so you should feel completely at home with modern JavaScript, component-based UI design, RESTful (or GraphQL) APIs, and the usual DevOps steps that get everything running smoothly in the cloud. The exact product domain is still flexible; what matters most is clean architecture, clear code, and a smooth hand-off. I’ll bring the product vision and designs, you’ll bring the full-stack expertise to: • set up the project structure and repository • build the React interface with reusable components and state management best p...

The core of my project is an API service already running on .NET 5 and paired with an Angular front-end. I need hands-on, task-based support to keep new features moving quickly while maintaining clean, testable code. Here’s the current stack and workflow so you know what you’ll be jumping into: • Backend: ASP.NET Core 5, Entity Framework Core, RESTful endpoints. • Front-end: Angular (latest stable), RxJS, Material. • DevOps: Git, pull-request reviews, CI builds on GitHub Actions. Typical tasks you could pick up include: • Expanding endpoints and DTOs. • Wiring new Angular components to the fresh endpoints. • Adding unit / integration tests where coverage is thin. • Fine-tuning performance or refactoring when technical debt appe...
I’m in the middle of a CROMA overhaul and the single, driving objective is to refresh existing features by squeezing every last millisecond out of them. No new bells and whistles—just a focused performance pass aimed at raw speed. Here’s the picture: React on the client side, Node.js/Express talking to a MongoDB cluster, all containerized in Docker and running on AWS ECS. I already have baseline profiling data and a staging environment waiting; once we start, you’ll get full access so you can re-profile, isolate the slow spots, and rewrite or refactor whatever is holding us back. Deliverables • A set of well-commented code changes or configuration tweaks • A before-and-after benchmark report (same test suite, same hardware) showing at least a 35 % dr...
