10+ years in aerospace, guiding companies through the entire journey of building a physical product — from first idea to reliable, manufacturable reality. I advise on the decisions that make or break a product: embedded electronics and firmware design, industrialization, production setup, and supplier selection. Whether you're validating a concept, preparing for volume, or fixing a stalled project, I bring a global view that connects hardware, software, and manufacturing. My background spans embedded development (real-time, high-temperature, digitally-controlled power supplies), production management, and supplier quality (100+ audits) — plus a custom MES built from scratch to control manufacturing. My strength is making the complex simple, so you make the right calls at each stage. I work under NDA, which is why my public profile stays intentionally light. Let's talk about your project.
