About

Engineer first, problem-solver always

I am a software engineer with more than six years of experience turning rough product ideas into services people rely on daily. Most of my work sits where the backend meets the browser: designing data models, shaping APIs, and making sure the interface on top feels instant.

I care about the unglamorous parts of the job — readable code, meaningful tests, clear migrations, and dashboards that tell you the truth. On recent teams I have trimmed page loads from seconds to milliseconds, replaced brittle cron scripts with proper queues, and mentored junior engineers into confident code reviewers.

Outside of work I write about system design, contribute small fixes to open-source tooling, and spend a fair amount of time tuning my terminal setup.
