Developer Chats - Oleksandr Piekhota

Episode notes

Today, we are continuing our series, entitled Developer Chats - hearing from the large scale system builders themselves. In this episode, we are talking with Oleksandr Piekhota , Principal Software Engineer at Teaching Strategies . Oleksandr helps to show us at what point of scale platform approaches are required, when to run experiments and when to stop, and perhaps more importantly - engineering ownership beyond the code. Questions You’ve moved from hands-on engineering into principal and technical leadership roles, working on architecture and platforms.At what point did you realize your work was no longer about individual features, but about the system as a whole Across several projects, growth didn’t break functionality — it exposed architectural limits.Can you recall a moment when it became clear that shipping more features wouldn’t solve the problem, and a platform approach was required? You’ve designed and supported APIs end-to-end, from architecture to real customers. How do you distinguish between an API that simply works and one that can truly support business scale?
