Summary
🤩
Rockstar🎓
Top SchoolCarlos Calvo is a Staff Backend Engineer based in Barcelona with 12 years building high-traffic, game and web backends across languages like C#, Go, PHP and tooling from Redis to Elasticsearch. He has driven major infrastructure work at Scopely—leading a top-engagement game mode, real-time friends/party systems with socket messaging, and large-scale migrations including a 120M-record chat migration and a zero-downtime Elasticsearch upgrade. Comfortable across microservices, DevOps and CI/CD, he also improved build/deploy flows in open-source projects (e.g., automating gh-pages deployment in Couscous). Known for pragmatic refactors and high test coverage, he has repeatedly translated legacy monoliths into maintainable services while keeping thousands of RPMs stable. Colleagues rely on him for ownership of performance-sensitive systems and mentoring on clean architecture and testing. He combines gamer-focused product impact with a curiosity to try new stacks and tooling.
