Summary
👤
Senior🎓
Top SchoolHarry Coin is a seasoned systems architect and founder with over three decades of experience designing end-to-end hardware and software solutions that have supported teams from small workgroups to global manufacturers. He specializes in embedded and realtime systems, device drivers, high-availability infrastructure, and full-stack enterprise applications—delivering durable, well-documented platforms that have remained in production for decades. Notable projects include a military-grade realtime driver-to-UI ecosystem, an ERP/CRM for wholesale baking that produced granular variance-driven management reports, and system software that extended a production line’s life by seven years. Comfortable shifting between low-level firmware (assembly, C/C++) and higher-level systems (Python, SQL, PHP, Linux/Windows), he also advises on technology due diligence and has served on corporate boards. An unusual but telling detail: he’s published minor original work in pure mathematics and has taught digital forensics at the university level, reflecting both deep technical breadth and academic curiosity.
