What I'm looking for

I seek backend or full-stack roles building scalable, secure API-driven systems with strong DevOps practices and collaborative teams.

I am a software engineer focused on backend and full-stack development, with hands-on experience building scalable services using Python, Django, FastAPI, microservices and PostgreSQL. I design performant RESTful APIs, optimize databases and integrate secure payment systems while maintaining strong Unix-based operational practices.

At Parkit I led backend architecture, implemented asynchronous high-performance APIs, deployed containerized services with Docker on cloud platforms, and guided frontend-backend integration with React Native apps. I also performed code reviews, managed a small development team, and introduced caching, indexing and security measures to improve reliability and latency.

My academic and personal projects — including OS extensions in C and robotics competitions — reflect a strong foundation in systems programming, concurrent processing and embedded/robotics solutions. I am eager to contribute to teams that value scalable design, continuous learning and pragmatic DevOps practices.
