Principal Python Developer | FastAPI, Django, React, AWS | Full-Stack

I build and maintain backend systems using Python and FastAPI, with React on the frontend, to help teams launch real products - fast, scalable, and ready for production from day one.
I use AI coding tools (Cursor, Claude Code) to reduce time and budget.

I bring 10+ years of experience in modern full stack web development, delivering real-world systems for U.S. clients - ranging from API-driven backends (FastAPI) to React interfaces and secure deployments on AWS.

Clients hire me for clean architecture, clear & fast communication and dependable delivery on long-term projects.

My specialties:

- Scalable Backend Architecture
I build backend systems using Python, Django, FastAPI and AWS (Lambda, EC2, DynamoDB). Whether it's a small MVP or a high-traffic platform, my architecture ensures your application can handle rapid user growth without compromising performance.

- Responsive Frontend Development
Over a decade of JavaScript frontend development: React developer and team leader, Expo, React Native and dozens of frameworks.

- Custom Python Applications
I develop custom Python services, internal tools, scrapers, background jobs and data pipelines - often with AI features. I go beyond generic OpenAI API calls, I specialize in custom models using tools like ComfyUI & StableDiffusion, N8N, LangChain and RAG for advanced image, text and data workflows.

- Full Stack Delivery & Deployment
Owning features end-to-end - from API design to frontend integration and deployment - with focus on reliability and long-term maintainability.
