Senior Backend / Full-Stack Engineer with 10+ years of experience building scalable backend systems and complex full-stack solutions using Python and modern JavaScript frameworks. I specialize in designing and fixing systems that must work reliably in production - systems that grow over time, handle real load, and don’t collapse under new requirements. My focus is clean architecture, clear separation of concerns, and backend-driven design that reduces long-term costs. I work best on complex problems where experience, structure, and ownership matter more than just writing code. What I can help you with: - Backend development with Python (Django, FastAPI, Flask, Celery, Redis) - Designing and optimizing high-load APIs - Building and refactoring data-intensive systems - Integrating AI / LLM solutions (including offline models) - Performance optimization and scalability issues - Complex integrations (payments, messaging platforms, external APIs) - Full-stack features with modern frontend tooling - Chrome extensions tightly integrated with backend services - Web scraping and automated data pipelines How I work: I don’t just “write code”. I design solutions that: - are stable in production - are easy to extend later - reduce long-term maintenance and infrastructure costs - I take full ownership of the result - from architecture and implementation to deployment and long-term support. Why clients hire me: - I understand business impact, not just technical requirements - I think in systems, not tickets - I communicate clearly and proactively - I’m comfortable working independently on complex problems If you’re looking for a senior engineer who can build or fix serious systems, let’s talk.
