Top SchoolKacper Bielecki is a Lead Software Engineer based in Berlin with 14 years of experience designing high-throughput, data-driven systems and real-time recommendation engines. He has led architecture and implementation efforts for scalable microservice platforms handling millions of events per minute and thousands of events per second, combining Scala, Akka and AWS with applied machine learning. Comfortable both as an individual contributor and a team lead, he has overseen reporting, ranking and monitoring teams while running technical interviews and shaping office-level technical direction.
