About me
Backend engineer with 9 years of commercial experience in PHP 8 / Laravel, focused on high-traffic e-commerce, performance work and third-party integra9ons. Spent five of those years working directly with a Norwegian client team — requirements, es9mates and technical decisions in English, with full ownership of producion behavior. I also build and run my own products end to end: an open-source WooCommerce plugin with 8,000+ ac9ve installa9ons (4.8/5) and Traxoria, a SaaS I designed, shipped and operate solo — Laravel backend, REST API, PWA, Android release, Docker infrastructure on a Linux VPS, monitoring and incident response
