I've managed Dawid for over a year and he's one of the smartest and most solid people I've ever worked with. He's extremely detail-oriented, fast, independent, hard-working, but also fun to be around. He's been an asset to his team from day one, often driving projects forward by advising both frontend and backend developers, explaining things to clients, identifying UX/UI issues for the designers, and providing swift support to QA testers. He's great at following direction while always thinking critically and independently. Dawid is also a good problem solver – I can always trust that if there are issues with the plan, Dawid will find them and bring them to me our to the team, with a suggestion for how to solve them.
