Senior🎓
Top SchoolGeorge Popides is a senior software engineer with seven years of experience building scalable, fault-tolerant backend systems from the Netherlands. He specializes in Kotlin (Spring Boot) and Go for service-oriented architectures, with hands-on expertise in GRPC/Protobuf, JOOQ-powered SQL optimizations, and observability via ELK/Fluentbit. George also brings functional-programming chops—working in Elixir and OCaml—and contributes backend improvements to notable open-source projects like Livebook, adding features and robust node/server management. He focuses on performance: identifying bottlenecks, refactoring hot paths, and applying asynchronous concurrency patterns such as Kotlin coroutines to boost throughput. Comfortable across the stack from databases to inter-service APIs, he pairs pragmatic engineering with a taste for elegant, smaller codebases. Based in North Holland, he combines production-grade backend delivery with an active interest in distributed systems and developer tooling.
