00Background & Experience

Building software that is fast, clean, and reliable.

I am a Full-Stack Web Developer with 1.5+ years of hands-on production experience building modern web applications, REST APIs, and browser extensions using Next.js, React, Laravel, and MySQL.

At Devonsite, I build and maintain production Laravel backends and React frontends. My day-to-day work includes designing database schemas, writing composite indexes to optimize slow queries (reducing query latency by ~40%), creating role-based access control (RBAC), and delivering responsive client portals.

I use modern tools like Cursor and AI coding assistants to handle repetitive boilerplate and write tests faster, while keeping full personal responsibility for database architecture, security boundaries, and code maintainability.

Alongside client and agency work, I've built and launched products including Prospetra (an automated website audit tool), Halvex Group (a B2B export website for an international manufacturer), and 10 live Chrome extensions currently used by real users on the Chrome Web Store.
