Hi, I’m Serhii 👋

I’m a Software Engineer/Architect based in London, UK, with 20+ years of experience in software engineering and networking. I specialise in designing and building scalable, distributed systems, cloud-native platforms, and microservices - primarily in Go.

Career highlights

Over two decades in tech, spanning networking, infrastructure, and software engineering. I started out maintaining computer labs and teaching students while studying, then spent over a decade building and running ISP networks - fibre-optic infrastructure, BGP routing, billing systems, cloud hosting, and VoIP. Since then I’ve designed and delivered gRPC/REST microservices, event-driven pipelines, and platform infrastructure across a wide range of industries: fintech, AdTech, healthcare, food delivery, social networking, and car rental. Along the way I’ve authored payment integrations from scratch, built real-time proxies, led backend teams, contributed to Kubernetes operators, and migrated legacy monoliths to Go.

This Blog

I write about things I build and learn - covering software engineering, distributed systems, cloud-native infrastructure, databases, design of programming languages, and whatever problem I’m currently solving or find interesting.
