About

I build maintainable applications with Python, JavaScript, SQL, and modern cloud tools. My work spans backend APIs, authentication, real-time interfaces, reporting workflows, and AI-assisted product features.

I care about simple architecture, secure defaults, clean interfaces, and systems that are easy to understand after the first version ships.

Currently focused on Python, Django, Flask, SQL, cloud technologies, and AI/ML integration.
