A project can connect your website, staff dashboard, and mobile app to a shared backend and database.

Senior full-stack engineer with 12 years of experience — Java, Python, TypeScript. I build AI features into real production systems. Most of my work falls into three areas: • Backend & APIs • AI integration • Full-stack delivery Ten years in enterprise software in Sweden taught me the part that actually matters on a freelance project: scoping honestly, telling you when an idea won't work, and shipping something maintainable instead of a prototype that breaks on the second change request.
