I used to sequence data in a lab. Now I turn real problems into software that works.

About

// biology → dev

I treat backend the way I once treated the lab: hypothesis, measure, iterate.

Research left me with a reflex I never dropped: I don't trust a result I can't reproduce. In the lab that meant running the measurement again; here it's a log confirming what I think happened, or a test that fails when it should.

I'm backend-first. I can hold my own on the frontend, but I earn my keep a layer below it: in how the data is modelled and in what happens when more load turns up than anyone planned for.

With agentic AI (Claude Code, MCP) I don't improvise. I write the spec myself, edge cases included, and the agent builds against it. The code then goes through the same gates as anything else: tests, review, monitoring. Whatever doesn't clear them gets rewritten.
