About Me

I am a backend-focused software engineer who learns by building real systems and understanding how they work under real constraints. My strongest experience is in Python-based backend development using FastAPI, where I design clean REST APIs, structure backend logic, and implement secure authentication and real-time communication features.

I am particularly interested in how backend infrastructure supports modern AI-powered applications—from handling data pipelines and model inference to ensuring APIs remain scalable, secure, and maintainable. My learning approach is practical and system-oriented: I prefer building, testing, breaking, and improving projects rather than following surface-level tutorials.

Currently expanding my backend skill set by learning Node.js to strengthen my understanding of cross-stack backend development.

Beyond Code

I follow books, world politics, global affairs, economics, financial markets, and technology policy. I also enjoy writing and closely follow Formula 1 and football.
