Summary
👤
SeniorSen Hongo is a technical founder and seasoned software engineer with 11 years of experience turning concepts into market-ready products, currently leading Millefe K.K. and bringing Chubic to market via aeco light. He has driven end-to-end systems architecture and product delivery—from a multi-source lighting fixture database and in-browser visual planners to M&A and whiteboarding platforms. Comfortable spanning frontend architecture, data structures, and backend integrations, he often combines engineering and design responsibilities to ship polished prototypes. Sen has a track record of taking solo-led projects to production (millefeuille.app) while also leading rewrites and performance improvements on team projects like Strapp and Prott. Based in Nagano, he blends hands-on coding with product sensibility and practical tooling for niche industries such as lighting and construction. Outside work he’s a snowboarder, bringing the same iterative, risk-aware mindset to both product development and the slopes.
