I help turn early-stage ideas into working products, especially when requirements are still unclear. I often work with founders and non-technical clients to clarify scope, user flow, and technical direction first—before jumping into development. I translate business inquiry into clear business requirements, then into practical technical functional requirements, so architecture, scope, and trade-offs are explicit from day one. My preferred approach is staged delivery: starting with a functional prototype or MVP to validate direction early, then expanding only where it creates real value. This keeps expectations clear, reduces risk, and allows teams to move fast without overbuilding. I’ve built and shipped IoT and mobile applications—from concept to production—and I’m comfortable bridging real-world business needs with hands-on technical execution.
