Top SchoolSebastian Engel is a Berlin-based mobile engineer and founder with 13 years of hands-on experience and a decade-plus focus on mobile apps, now leading Antigua Mobile GmbH to deliver app development and developer staffing. He specializes in Flutter while bringing deep Android roots—having led architecture, testing, and team practices for clients from AOK and ImmobilienScout24 to fitness brands like McFit and John Reed. As a frequent freelancer he’s delivered everything from iPad order terminals to hardware-integrated camera apps, showing a knack for taking diverse product ideas to production quickly. Sebastian combines entrepreneurial instincts (co-founding a BaaS early in his career) with pragmatic engineering discipline, including introducing Git Flow, code reviews and test-driven approaches on client projects. Despite a broad client roster, he still prefers being hands-on in code and coaching teams to raise mobile development standards.
