I build web applications, API integrations and digital products — from backend and data modeling to interfaces and launch. I work mainly with Laravel/PHP and React/Next.js, and I develop automation workflows with AI agents.

About

Full stack web developer from Bucharest, Romania, with 10+ years of experience working in software companies. I've worked 5+ years with Laravel extensively, from telecom platforms to marketplaces. JavaScript is my favorite language: vanilla JS, jQuery and modern frameworks (React, Angular, Vue). In parallel I'm building my own AI operating system — a multi-agent fleet, provider routing with fallback and local inference.
