I build and maintain Python backends, APIs and integrations for web applications. My work covers Django/FastAPI services, background workers, data pipelines and AI features connected to external tools. If you have an existing application to finish or extend, I can review the code, agree a clear scope, implement the changes and document the handover. Work I take on - Backend development and maintenance with Python, Django and FastAPI - API integrations, webhooks and connections between business systems - Background jobs, queue-based processing and AWS SQS workers - PostgreSQL schema/query work and Redis caching - AI tool calling, agent integrations and read-only MCP servers - Debugging, testing and deployment support My completed Upwork contracts include Django backend development, full-stack applications and AI-agent work. I also built Wavo, Swipa and LyraBuild solo: an AI product-photography platform, a Telegram prediction app and a Hyperliquid research project with read-only MCP access. Rust and TypeScript are also part of my stack, alongside AWS, Docker and Git. For specialist work, I will be clear about what I have implemented and the evidence I can share. Send a short description of your application and the feature, integration or issue you want help with.
