I'm 27, with a B.Eng. in Mathematics and Computer Science. Most of my work is the unglamorous part of backend: keeping data correct and keeping services up when traffic spikes. The rest is paying down the debt that slows everyone down, and I care more about the tradeoff behind a decision than the tool used to make it. These habits came the hard way, on high-traffic services where a bad query or a missing index shows up as a page, not a review comment.

A lot of that lives in infrastructure now: cloud and containers, with infrastructure as code so environments are reproducible instead of hand-built. I lean on AI across the whole build, from writing the spec to the implementation to the review, and I wire LLMs into products that have to survive past the demo, with security standards enforced at each step instead of bolted on at the end. Backend is home base, but I'll build the frontend when a feature needs it.
