"I care about clean code, performance, and systems that don't break at 2 AM."

I started my career in backend development with Python and Django, working on healthcare and IoT systems. Over time I transitioned into data engineering, where I now focus on pipelines, data processing, and system reliability.

I've led teams, shipped production features used in multiple countries, and made open-source contributions. I approach every problem by first understanding the business need, then translating it into a technical solution that scales.
