Summary
👤
SeniorJonathan Massuchetti is a Principal Software Architect based in Paris with 11+ years of hands-on experience designing and scaling resilient platforms across startups and enterprise environments. He drives technical transformations from legacy to modern architectures, balancing fast experimentation with long-term maintainability while avoiding single-expert lock-in. Jonathan has repeatedly rescued time-critical projects and led platform-level initiatives—recovering delivery at Mômji, scaling a PFM system at Boursorama by 75x, and building a real-time video processing platform used by major French companies. He blends backend systems expertise (including contributions to the Lisk SDK improving state management and network APIs) with front-end architecture work like defining micro-frontend patterns and accessible design systems. Known for enabling teams rather than creating dependencies, he focuses on measurable business value early and raising developer experience and accessibility standards across organizations.
