I design and build scalable backend systems and cloud-ready architectures that power real-world applications. With over 5 years of hands-on experience, I specialize in building secure, high-performance systems using Python and modern distributed technologies.

My engineering philosophy focuses on clean architecture, performance optimization, and long-term maintainability. I enjoy transforming complex business requirements into reliable, production-grade systems that scale efficiently and remain easy to evolve.

Backend Engineering

Python, Flask, FastAPI, Django, REST APIs, JWT, Celery

Microservices & Distributed Systems

Service-oriented architecture, asynchronous processing, scalable system design

Cloud & Infrastructure

Docker, Nginx, Linux, PostgreSQL, Redis, performance optimization

"

Great systems are not just built to work — they are built to scale, adapt, and remain maintainable under real-world pressure.

Let’s build scalable systems together

If you're looking for a backend engineer who understands both architecture and real-world production challenges, let's connect and create robust, future-ready solutions.
