Senior🎓
Top SchoolJohn Ellinwood is a seasoned technology leader and Vice President with roughly two decades of experience blending hands-on software engineering and executive leadership from Maryland. He founded and runs technical and business operations at Nissint Technologies, overseeing everything from product design and project delivery to customer management, HR, finance, and security—demonstrating a rare full-stack view of what it takes to run a small technology company. Earlier roles as a senior software engineer and computer scientist at companies like KEYW, Essex, Sybase, and Northrop Grumman underscore deep systems and engineering chops rooted in a Computer Science BS and an MS in Technical Management from Johns Hopkins. Known for a maker’s mindset (“anything from B-trees to tree houses”), he pairs low-level technical fluency with strategic business execution and recruiting acumen. Notably, he continues to steer technical direction while handling the day-to-day operational responsibilities that many executives delegate, keeping him close to both code and customers.
