Software Engineer · Systems Builder
Full-stack and backend engineer with a DevOps and systems background. I design and ship end-to-end systems — including a full stock-market application. Alongside that, I run independent, data-driven research on financial markets.
Selected work
Two or three deep case studies — problem, architecture, decisions, trade-offs, results. Depth over a thumbnail gallery.

How I work
I work across the stack — backend, DevOps, and system architecture — and I care about correctness, reliability, and systems that hold up in production. I approach problems the way I approach research: understand the constraints, make deliberate trade-offs, and verify against reality.
Markets research
For 3+ years I've researched how markets behave — equities, options, and futures — as a systematic, data-driven discipline. I form a hypothesis, test it against data, and pay attention to where it breaks. Method and limitations, not predictions.
