Bio
Chisom Emegoakor
David is one of the most impressive engineers I've ever met. He and I met frequently to create a control scheme for his exhaust conditioning system at Remora. I always felt valued and heard when working with David. He asked for feedback on his ideas often, and I could tell that he folded that feedback into his thinking. Despite the stressful startup environment, David created a truly astounding amount of hardware, proactively involved teammates across the organization to stay ahead of design or system integration challenges, and still made time to manage interns and help other engineers with their projects. In addition to quantity, I was most impressed by the quality of David's output - when he prototypes something it simply works, and usually it works exceptionally well. I cannot recommend David highly enough!

It was a pleasure working with David at Remora. His ability to retain focus and composure in a fast paced and stressful work environment helped keep our team safe and heading in the right direction. David's wealth of technical knowledge and practical engineering shone through his creative problem solving and flexible engineering solutions every day. This involved creating his own system while ensuring it would mesh with the rest of the subsystems. As a fellow mechanical engineer, I greatly appreciate David's ability to visualize and verbally break down complex engineering concepts. This made him a valuable mentor to his interns. When tasked with designing a system outside of his specialty, David researched independently and developed relationships with heat transfer consultants and major automotive OEMs in order to build a novel 6-stage prototype. Beyond his technical expertise, David is a pleasure to be around; he always kept a positive and mission-first attitude and never let his ego obscure his judgement. I confidently recommend David!
