Senior backend engineer specializing in Golang, microservices, and scalable systems.
What I'm looking for
I am a senior backend engineer with a decade of experience building and refactoring backend platforms, specializing in Golang, Java and microservices. I focus on clean code, solid architecture and continuous integration to deliver reliable systems.
At Svitla I contributed to Fuel Supply Chain solutions, migrating legacy Java systems to performant Golang services and began leading a seven-person team. My work improved response times and user experience while collaborating across a 15–20 person team of devs, QAs, product and managers.
Previously at RappiPay and CommonBond I led architectural overhauls and rewrites of monoliths into modern Golang platforms, improving code quality and performance. I have designed and implemented services from scratch, created REST APIs, and integrated Kotlin libraries where needed.
I bring hands-on experience across cloud platforms (AWS, GCP), containers and orchestration (Docker, Kubernetes), messaging (Kafka, NATS), and multiple databases (MySQL, Postgres, Mongo, Redis). I am proactive, a team player, and currently building and selling AI agents using n8n.
