Summary
👤
Senior🎓
Top SchoolPavel Kalandra is a pragmatic software leader and CTO with 11 years of experience building and scaling backend systems and leading cross-functional engineering teams from Prague. He combines hands-on technical craft—optimizing .NET performance, redesigning monoliths, and improving developer tooling—with proven people leadership, having grown and coached multiple engineering managers and led a 15-person tribe. Pavel excels at change management and aligning team structure to product domains to give engineers end-to-end ownership while preserving technical quality under tight deadlines. He has a track record of making work easier for colleagues through critical thinking and redesign, from cutting application startup times by 61% to rolling out major breaking changes without customer impact. Comfortable both in deep technical roles and in hands-off management, he prefers small, empowered teams (single-pizza) and isn’t afraid to challenge the status quo. Outside work he channels competitive instincts into games and racing—having raced 190cc go-karts and eyeing Mazda Miatas next—bringing a racer’s focus to delivery and continuous improvement.
