What I'm looking for

I'm looking for a backend development role where I can build scalable APIs and database-driven applications, write clean maintainable code, and grow through hands-on work with modern backend frameworks and cloud technologies.

I've built backend systems for e-commerce, real-time chat, and digital-store applications using Python, Django, Node.js, Express.js, MongoDB, PostgreSQL, Redis, and Docker.

For an e-commerce API, I reduced database queries by 65% and improved frequent API response times from 800ms to 120ms with Redis caching. I also designed indexed PostgreSQL schemas across 8+ tables and integrated Stripe webhooks for payment-status updates.

I'm focused on clean, maintainable server-side code, RESTful APIs, authentication, database performance, and robust backend solutions for real-world problems.
