Summary
👤
Senior🎓
Top SchoolMarcelo Rishmawy is a Principal Engineer based in Stockholm with over two decades of hands-on experience and a 12-year track record focused on building scalable, high-performance backend platforms for games and large-scale services. He has recently been designing core platform infrastructure for an unannounced title at Blizzard after leading architecture and performance efforts on game backends at King and partner-integrated microservices at Spotify. Known for pragmatic system design, Marcelo combines deep Java expertise, cloud-native patterns (Kubernetes, GCP), and a history of solving high-availability and concurrency challenges for mission-critical systems that handle millions of transactions. He also mentors and grows teams—having built a software group from scratch in manufacturing—and moves fluidly between hands-on refactoring (as shown by his work modernizing a Java text-adventure repository) and high-level architecture. Comfortable across mobile, web, and backend stacks, he brings a steady focus on reliability, observability, and operational excellence. An engineer who started in legacy integration and ERP environments, he still brings that systems-integration perspective to modern platform problems.
