What I do

I build reliable web products for small and mid-sized businesses — real estate agencies, SaaS companies, photographers and everything in between.

Six plus years of TypeScript, React and Next.js experience. Currently a Principal Solution Architect at E.ON, previously at StudySmarter and Memberspot. I know the performance, maintainability and compliance bar a website needs to clear when it actually carries the business.
