Profile

Web developer with 15+ years of experience building solutions that perform, both technically and commercially. My strength is taking a task all the way, from need to production, and I care deeply about optimisation and about finding the places where a little automation or a sharper workflow saves time every week.

Day to day I work mostly with Laravel and API integrations, AI and LLM integrations, and workflow automation. I build things like RAG solutions and AI agents, and I use AI actively in development itself with Claude Code, Codex and Copilot, where responsible use of AI and data governance are a fixed part of the way I build. On top of that comes custom WordPress and plugin development, technical SEO and performance, plus Linux operations and security.

At GoLearn I have been responsible for internal systems, server operations and automation, and was technically responsible for the migration to Eduhouse LMS following the acquisition in 2023, where a platform with tens of thousands of users was moved with close to zero downtime. I have also co-founded CustomerFlow, an AI-driven SaaS product that profiles customers' communication style via DISC, where as CTO I am responsible for the entire technical architecture. Through Kodesmeden I help companies with custom Laravel development, integrations and technical consultancy.

I am now looking for a permanent position where I can put down roots and help take a company forward. A place where technical quality is taken seriously, and where we build things that perform and last.
