Founder & Technical Lead
Daniel Killyevo is the founder of Design Key, a software studio in Tampa, Florida. He started it in 2022, after fifteen years building software inside other companies where he kept watching clients receive exactly the build they asked for and not the product they needed.
He holds a Master's degree in Computer Science from Poltava National Technical University (2005-2011). Born in Tanzania to a Ukrainian mother and a Tanzanian father and raised in Ukraine, he now runs the studio from Tampa.
Daniel has more than 15 years in software development and product design and has delivered more than 50 web and mobile applications. He began his career as a developer and went on to work at Ciklum, at Corrigo before Terminix acquired it, and at JustEat, building products for companies at every stage from first customer to established revenue.
His own work centres on architecting cloud-based systems, API and data integration, and building and scaling engineering teams. He has founded two software agencies.
