    I’m planning a tailor-made solution that will evolve as the concept takes shape. At this stage the exact feature set is still fluid, so your ability to switch between front-end and back-end tasks, recommend the best tech stack, and iterate quickly will be key. Here’s what the collaboration will look like: • We start with a brief discovery call where I walk you through the current vision, user flows, and any constraints. • You propose an architecture that strikes the right balance between scalability, maintainability, and delivery speed. • Work proceeds in short, testable milestones. I review each build, give feedback, and we adjust scope or priorities as needed. • Clean, well-commented code is committed to a shared repo; deployments are automated ...

    I’m building a PHP + React gaming platform and I’m ready to expand it with live game feeds.

    Project Overview I am seeking an experienced full-stack developer or small team to audit, improve, secure, and modernize an existing production website and infrastructure. This is **not a greenfield project**. An existing frontend, backend/API, PostgreSQL database, content, media, forms, administrative functionality, Docker deployment, and VPS environment are already in place. The current website has experienced intermittent outages and loading failures. Based on prior troubleshooting, the likely problem area is a combination of deployment/runtime stability and security rather than a simple frontend bug. Known symptoms/issues include: Website sometimes hangs or times out while Docker containers still appear to be running. Nginx and Docker are functional, but the deployment is not yet ...
