About this service

Summary

I specialize in building scalable and high-performance backend systems using Django, Flask, and Node.js, with expertise in API development, database optimization, and system architecture. My experience integrating caching (Redis), authentication (JWT, OAuth), and third-party services (Stripe, OpenAI) ensures seamless and efficient applications. With a strong problem-solving mindset and a focus on clean, maintainable code, I deliver robust, production-ready solutions tailored to client needs.

What's included

End-to-End Web App Development
I develop full-stack applications using Django/FastAPI for the backend and React for the frontend. From authentication to deployment (Docker, Render, AWS), I deliver production-ready solutions tailored to client needs.
Backend Optimization & Performance Tuning
I enhance backend performance by implementing caching (Redis), optimizing database queries (SQL, PostgreSQL, MySQL), and improving response times, ensuring scalable and efficient applications.
API Development & Integration
I design and build robust, scalable APIs using Django, Flask, or Node.js. From authentication (JWT, OAuth) to third-party integrations (Stripe, OpenAI, Telegram), I ensure seamless and secure API communication.
