PROFILE / 001

I studied Engineering Physics — not as something I moved past, but as the way I still think about problems: as systems that can be modeled, measured, and computed.

That led through data science and quantitative/financial work before settling into backend engineering, real-time systems, and applied AI — each one adding to the last rather than replacing it. The common thread isn't a job title, it's the habit of understanding a system, modeling it, and building software around it.

Right now that's production backend infrastructure, data platforms, and AI systems. Where it's heading is physical: electronics, sensing, and embedded computing — software that doesn't stop at the API boundary.
