About

I’m a Senior Lead Engineer at Synapse Innovation (Tokyo) with 5+ years leading the design and delivery of scheduling platforms that power manufacturing operations across Asia and Europe. My work has directly improved throughput, reduced idle time, and enabled factories to respond to production shocks in real time. I’m also the Founder of Interview Sensei an AI-powered interviewer that has run 1,000+ mock sessions for engineers worldwide, pushing them to master scalability, trade-offs, and architecture storytelling under pressure. KEY PROJECTS & IMPACT • Gantt Scheduling Engine: Scaled a multi-tenant platform handling 10k+ concurrent tasks, helping manufacturing customers rebalance machines, materials, and shifts instantly. • AI-Driven Production Optimizer: Designed distributed solvers on Azure and AWS that cut scheduling latency by 90% (hours → minutes) while adapting to supply and workforce constraints. • Workforce Allocation Platform: Built shift-planning software used daily by hundreds of workers across plants, optimizing labor costs, compliance, and SLA commitments. • System Design Mock Interviews (Alex): Created a platform now trusted by engineers preparing for Big Tech interviews — delivering real-time feedback on bottlenecks, failure modes, and scalability choices. NOW • Refining mock system design workflows with Alex — decomposing large architectures into modular, testable designs. • Practicing meditation to sharpen focus, the same way I approach debugging race conditions and deadlocks. WHAT I SHARE HERE I write about system design at scale, lessons from building scheduling platforms in production, and insights from running mock interviews with engineers worldwide. MY OPINIONS ARE MINE ALONE AND NOT MY EMPLOYERS 👉 If you’re building reliable systems, scaling teams, or mentoring engineers, follow along — I share what works (and what breaks). 🚀
