Summary
👤
Senior🎓
Top SchoolYannick Grenzinger is a Senior Software Engineering Manager with 13 years of experience building high-performing teams and shipping production-focused HR and B2B products. He blends hands-on engineering (NodeJS, Java, TypeScript, AWS, event-driven architectures) with a strong emphasis on Domain-Driven Design, testing discipline and DevOps to deliver scalable, maintainable systems. At PayFit he built and grew an HR Suite team that reclaimed storage control, halved document support and launched major features like 360 feedback; previously he led cloud migrations and payment platform scaling in fast-growth startups. A practitioner of Kanban, Lean product management and intent-based leadership, he pairs flow-focused delivery with UX and design-thinking to align technology with customer value. Outside work he contributes UX improvements to community repos and, less obviously, channels interests in psychology and martial arts (father of triplets and Systema practitioner) into team coaching and resilience.
