Lincoln E.

I turn ambitious hardware concepts into working, manufacturable products. I help startups validate designs, solve difficult engineering problems, and move from idea through prototype and production-ready documentation. I am a fractional CTO, chief engineer, inventor, and former Head of R&D at Northrop Grumman Marine Systems. I hold an MS in Industrial Engineering and Engineering Management from Stanford University and a BS in Naval Architecture and Marine Engineering from Webb Institute. My experience includes founding and leading technology companies and more than 30 years of multidisciplinary engineering. HOW I HELP • Complete product development: feasibility, requirements, system architecture, detailed design, prototypes, testing, and manufacturing preparation. • Design validation and rescue: review existing CAD, specifications, calculations, and AI-generated concepts; identify flawed assumptions; redesign systems that cannot meet real-world requirements. • Integrated hardware engineering: mechanical design, structural and thermal analysis, fluid systems, electrical and PCB design, embedded controls, power electronics, motors, batteries, and automation. • Fractional CTO / chief engineer: technical decisions, trade studies, development plans, supplier coordination, and engineering risk management. I work across disciplines when a product cannot be solved by a mechanical, electrical, or software specialist alone. My focus is on reliable, buildable solutions—not just attractive renderings or CAD models. ENGAGEMENT APPROACH For uncertain designs, I usually begin with a bounded feasibility or engineering review to establish technical risks, scope, and realistic next steps. Subsequent work can be hourly or divided into clearly defined milestones. I have earned more than $1M through Upwork and hold Top Rated Plus status. My goal is straightforward: turn your idea, preliminary design, or troubled prototype into a technically sound product.
