2,578 students started the course. A little over 100 reached the end. Around 30 completed all stages in full. Dastan was one of them.

His team won in two final project nominations: Engineering Excellence and Design Excellence.

Aliaksei Rudak

His code is clean, well-organized, and easy to read. His projects were consistently among the strongest in the course, especially when it came to UI styling and well-thought-out UX.

I believe Dastan has great potential and would be a valuable addition to any software development team.

Diana Khnizova
_{Junior Frontend Developer at Kaspi.kz

Dastan is not afraid of challenges, asks the right questions, and consistently sees tasks through to completion. He took ownership of results, supported team members, and was effective in building communication and maintaining team momentum.

I can confidently recommend Dastan as a promising frontend developer and team leader.
