Prooemium

An introduction

I am a senior full stack developer with over a decade of experience designing, building and running web products end to end, from the first database schema to the last pixel of the interface. I work best where product thinking meets solid engineering: turning ambiguous business goals into systems that are simple to reason about, pleasant to use and inexpensive to operate.

My daily tools are TypeScript, React and Node.js, backed by PostgreSQL, Go for performance-critical services, and cloud infrastructure on AWS described as code. I have led teams of up to eight engineers, broken monoliths into well-bounded services, and taken platforms from a few hundred users to several million without losing sleep or uptime.

Beyond writing code, I care about the craft around it: thoughtful code review, meaningful tests, clear documentation and mentoring the next generation of engineers. Like the builders of old, I believe good structure is invisible. You only notice it when it is missing.

“Firmitas, utilitas, venustas.” Strength, utility and beauty: Vitruvius’ three principles of architecture, and still my checklist for every system I ship.
