Senior🎓
Top SchoolMarcus Vieira is a startup-focused technology leader and Co-Founder & CTO based in Berlin with over 15 years of software experience and eight years in senior engineering leadership roles. He built and scaled Ostrom’s platform from pre-seed to Series B (€40M) as the first full-time engineer and CTO, and now applies that product-first engineering mindset to healthcare systems at Triosys. Marcus combines deep backend expertise across Java, Python, microservices, event-driven architectures and AWS with hands-on people leadership—hiring, mentoring and growing teams under fast timelines. His background in finance and insurance systems gives him a strong bias for reliability and compliance, while his startup track record shows he thrives on ownership and rapid iteration. Outside work he’s an avid learner and a football player, a detail that reveals his team-oriented, competitive energy off the keyboard.
