Web Application Developer

Piotr Usewicz

Building functional web applications with Ruby, Rails, and modern JavaScript. Based in Benicàrlo, Spain.

What I Do

Craft & Capability

Backend

Ruby on Rails applications built for longevity — clean architecture, fast queries, and APIs that other services can rely on. Fifteen years of production experience.

Frontend

Hotwire, Stimulus, and vanilla JS for reactive interfaces without the framework weight. HTML and CSS with care for performance, accessibility, and craft.

Full Stack

End-to-end ownership from database schema to deployed interface. Comfortable with the full lifecycle: architecture, implementation, ops, and iteration.

About

Two Decades
of Code

I've been writing software professionally since 2005 — first in PHP, then Rails from the very early days. Over the years I've built SaaS products, internal tooling, developer APIs, and consumer applications, usually as the person who owns the whole stack.

Today I work independently — consulting, contracting, and building products of my own. I care about readable code, sensible defaults, and software that stays maintainable long after the initial excitement fades.
