Rockstar🎓
Top SchoolAlexander Tesfamichael is a pragmatic software engineer and founder with 11 years of experience building web platforms, leading small teams, and advising early-stage projects. He started coding in high school and co-founded a web development company that shipped consumer apps (one with 300k+ downloads), later moving into senior consultancy and hiring roles at Reaktor before becoming self-employed. Alexander combines hands-on back-end expertise—contributing stability and robust error handling to the popular got HTTP library—with product-minded work in blockchain as an investor and builder. Known for thoughtful, empathetic collaboration, he assesses talent and shapes teams as deliberately as he writes code. Based in Amsterdam, he blends Computer Science and Economics training to balance technical depth with commercial judgment.
