I'm a senior software developer and tech lead with over 15 years of experience building web applications and leading technical teams across startups and large-scale platforms. My background spans the full stack, but I have a particular passion for architecture, IT security, and creating systems that are built to last. Beyond my professional engagements, I build my own products. Among them are gisformat.com, a tool for converting geodata between GIS formats and coordinate systems, and idvakt.se, a privacy-focused service that lets people check if their personal data has been exposed in known data breaches. These are just two examples of what drives me combining technical curiosity with real-world utility. Outside of work I'm a dad, a dog owner, and an animal lover.
