Senior Full-Stack Developer (5+ years) specializing in Node.js/NestJS, TypeScript, and PHP. Built production SaaS platforms (Strapi/PostgreSQL/Stripe Connect) and real-time systems (FeathersJS/MongoDB/Redis/MQTT). Also comfortable on the frontend with Next.js/React/Vue. I deliver clean, maintainable code following SOLID principles — happy to scope work directly with clients and hit agreed deadlines.
