PARIS MESIDIS
@parismesidis
Senior software engineer specializing in distributed systems, Go, and cloud-native architecture.
CyprusWhat I'm looking for
I am a senior software engineer with 13+ years of experience building backend systems, distributed services, and full-stack delivery across finance, telecom, and embedded domains. I specialize in Go and Rust, and I focus on cloud-native microservices, systems-level programming, and reliable payments and membership platforms.
Throughout my career I have designed and implemented backend microservices using REST/gRPC, Kafka, Kubernetes (EKS), AWS, Terraform, MongoDB and PostgreSQL, and I have maintained and extended core systems in Java, Spring Integration and C++. I have led teams, provided architectural guidance, and contributed to CI/CD and delivery automation to improve reliability and deployment velocity.
My hands-on projects include refactoring monoliths into microservices, building payment integrations, and implementing a Rust-based B+ Tree storage engine with copy-on-write semantics and epoch-based reclamation. I bring pragmatic engineering, mentorship, and a focus on scalable, maintainable systems.
