Andreas Coroiu is a tech lead and platform engineer with 12 years of experience building backend systems and frontend interfaces, currently leading platform efforts at Bitwarden while running his own consultancy, Pear Programming AB. He treats software as craft, favoring clean architecture and thoughtful code, and excels at distilling complex problems into shared understanding across teams. His contributions to the widely used open-source Bitwarden projects span server-side API and database work (including passkey and collection management) as well as client-side UX improvements, reflecting full-stack fluency. Comfortable in embedded and automation projects, Andreas brings hands-on experience from systems engineering to large-scale product work at companies like Volvo Trucks and PriceSpy. He pairs a Lund University master’s in Computer Science with curiosity-driven side projects and language study in Japanese, an uncommon mix that fuels both technical depth and cross-cultural perspective. Colleagues describe him as a calm, inquisitive leader who asks the right questions, teaches deliberately, and speaks up when it matters.
