Jan Bojko
cloud-native full-stack developer

I build web apps and the systems behind them. From Next.js e-commerce or web-apps to Go microservices that run on Kubernetes, with the monitoring and CI/CD pipelines.

About

Four years in, I've shipped a dozen production systems across e-commerce, internal tooling and dashboards. I started as a full-stack developer in TypeScript, React, Next.js; today I'm steering toward cloud-native full-stack development: distributed Go services, Kubernetes, GitOps and observability.

What I enjoy about software engineering is problem-solving, or those moments when an architectural decision pays off months later. I value clean architecture, deliberately defined boundaries, and tools that make life easier for the next person working on the repository.

Selected work

Smart Tracking System

Distributed cloud system simulating real-time telemetry from 50 cargo containers sailing from Busan to Rotterdam. Five Go microservices, event-driven over NATS JetStream, CQRS, clean architecture in every service, full GitOps pipeline (Tekton, ArgoCD), and the complete LGTM observability stack: Loki, Grafana, Tempo, Prometheus. Provisioned end-to-end with Terraform on a local k3d cluster.
