Christine Dumont - Captions.ai
Jakub is a great Android engineer. He owned building features from zero to done in our app with good velocity but also attention to quality, he was proactive in filling the blanks when the requirements or designs were lacking in details, allowing us to bring value to customers on a good pace. I appreciated that Jakub was also willing to help with tooling improvements as well as dig into technically complex issues, with good communication along the way.
Alberto Garza - Puul LLC
Jakub is an excellent developer. He led my project for a rideshare platform and made sure it was executed efficiently and with precision. He is very knowledgeable about the latest technologies and deployed the most advanced to date on the project. Great collaborator, and knows how to work with project managers and other team members. He was very responsive to my needs as a client, and very diligent in guiding other developers so that the project was built as quick as possible and with great integrity.
Craig Fransen - Ozma Technologies
Being a start up, we could only afford one developer. Jakub not only filled that role, but also contributed to architecture, as well as UX and application design. He is easy to work with, smart, and responsible.
