I’m running a server and I’m looking for an experienced developer to build a fully custom mining pool environment from the ground up. The setup should support two modes on the same server: a solo mining pool for Fractal Bitcoin (FB) using the SHA-256 algorithm, and a merged-mining pool that works with both Bitcoin (BTC) and Fractal Bitcoin at the same time. This needs to be a completely custom solution rather than based on existing pool software like MPOS or NOMP. You’re free to choose the programming language and framework as long as the result is stable, efficient, and well documented. Once everything is set up, my ASIC miners should be able to connect via Stratum and begin hashing without issues. The pool must fully support SHA-256 mining in both solo and merged modes...

I need a Shrek filter built in DeepAR Studio. The finished filter must run flawlessly inside a DeepAR-powered mobile app, so please optimise all textures. You’ll start from concept, create or adapt the 3D/2D assets, wire everything up in DeepAR Studio, and hand back a tidy, well-organised project folder. When I import it into my own DeepAR workspace and hit “Play”, the filter should track instantly. Deliverables • Complete .deepar project file with organised assets • Any custom textures, models or scripts used • Short video (or GIF) demo recorded in DeepAR Studio If you have previous DeepAR or similar AR face filter work, feel free to mention it so I can gauge style fit.

I need a clean, accurate database of 15,000 accounts-payable contacts at privately-owned companies across the United States. For every record I must have the person’s full name, job title, company name, corporate email, and direct phone. These addresses must pass an email-verification sweep (NeverBounce, ZeroBounce or comparable software) so the final file is ready for outreach with a very low bounce rate. My ideal file arrives as a single CSV or Excel workbook that includes the verification status for each email plus a summary report from the tool you used. Bounce-free delivery is essential; anything over 2 % will require replacement. Please source only true A/P decision makers—no generic “info@” or “sales@” inboxes—and avoid public-secto...

...I will need a brief hand-off session—screen-share or recorded video is fine—showing me how to add new groups, moderate chats and back up the database. If you already have experience building faith-based communities or have suggestions on technologies (WordPress with BuddyBoss, Laravel + Vue, etc.) that can deliver these features quickly and securely, let me know. My yardstick for completion is straightforward: every visitor can land on the site, register or log in, choose a group and immediately see the group chat working. When that flow is smooth and the admin tools are in my hands, the project is done. I need an extremely strong back in database person to run the scripts. I already have the scripting pretty much outlined exactly how we need to pull this of...

The project starts with a clean slate, so you’ll have full control over the architecture, folder structure, and tooling choices. Two capabilities must be rock-solid: • User authentication – Single-sign-on, role-based access control, token refresh, and secure session handling are required. • Integration with other systems – REST and/or GraphQL endpoints, webhooks, and potential third-party SDKs will need to be wired in so data can flow smoothly across our existing platforms. Beyond those essentials, code quality, unit/integration test coverage, and straightforward CI/CD pipelines (GitHub Actions or similar) a...

I have a backlog of financial figures that must be transferred accurately into working spreadsheets and then reflected in our existing SQL database. The spreadsheets will be the primary source, so precision in every cell—dates, currency formats, formulas, and cross-sheet references—is essential before the data is pushed to the database. You will receive scanned source documents, the current Excel template, and credentials to a staging schema in our SQL environment. Once each spreadsheet is complete and vetted for errors, the corresponding tables in SQL need to be updated so that our reporting dashboards stay in sync. Deliverables • Completed Excel workbook with all financial data correctly entered and formatted • SQL script (or direct upload) that ...

I need a complete food delivery application that runs smoothly on both Android and iOS.

Hi, ​I’m looking to commission a Fortnite map similar to "Escape the Tsunami for Brainrot" but with a twist. I want to keep the core UI and mechanics but replace the tsunami zone with a PVE combat system. ​Here are the specific features I need: ​PVE Progression: Instead of a rising zone, the map should feature video-game-style mobs (guards) and bosses. The further the player travels, the stronger the mobs become. ​Mystery Box Loot System: Killing mobs and bosses should drop Mystery Boxes. The quality and rarity of the box (and the Brainrot inside) depend on how far the player has progressed. ​Trading System: Include the in-game Brainrot exchange/trading mechanic from the original map. ​Double Economy & In-Game Shop: ​Brainrot Currency: Players earn money through their B...

...reachable through a personal sub-domain (for example, ). The workflow I need is straightforward: during registration the system must create—or virtually route—a sub-domain for the chosen username, store the basic user details, and immediately serve a minimal, clean profile page that shows only the user’s name, photo, and short bio. Security is crucial; the routing logic and database queries must ensure strict isolation so no account can touch another user’s data or files. I already have wildcard DNS support available (/*.); if additional server rules or vHost tweaks are required, include clear, step-by-step instructions so I can reproduce them on staging and production.
