Python and Java Developer Needed
Budget: $250 – $750 USD
I need an experienced python and java developer.
Must-Have Skills (Non-Negotiable)
Advanced Python (3.10+) with strong async/await and asyncio knowledge
FastAPI (production experience with async endpoints, WebSocket handling, dependency injection)
Celery + Redis (task queues, broadcast patterns, worker scaling, retries, Flower monitoring)
Docker & docker-compose (multi-container setups, volumes, networking, health checks)
Nginx + Let's Encrypt SSL (reverse proxy, auto-renewal, HTTP-to-HTTPS redirects)
Real-time WebSocket experience (python-socketio or similar, handling persistent connections, events like basicapi_*)
Redis (as both broker and shared state store for user/device sessions)
Strongly Recommended (For Reliable 5000-User Scale)
Horizontal scaling & distributed systems (multiple API instances behind a load balancer, auto-scaling groups)
Monitoring & observability (Prometheus + Grafana, or at least basic logging/metrics)
Cloud deployment (AWS ECS, DigitalOcean App Platform, Render, Fly.io, or Kubernetes basics)
Rate limiting & throttling (slowapi or custom logic for high-load scenarios)
Basic DevOps (CI/CD with GitHub Actions, environment variables, secrets management)
Nice-to-Have / Bonus Skills
Lovense Standard Socket API (or similar toy/hardware API experience)
Buttplug-py / Intiface integration
Audio processing (Librosa or similar)
Previous experience with adult/tech toy sync apps or real-time multiplayer systems
Kubernetes or Terraform for advanced auto-scaling
Experience Level Required
Senior (6+ years professional Python experience)
At least 2–3 shipped production apps with Celery + Redis + Docker at 500+ concurrent users
Proven ability to handle WebSocket-heavy real-time applications
