Cartoon of an engineer drawing system architecture on a whiteboard — cloud, gears, server racks, database, arrows.

Over the years, I've built scalable backend systems, led teams across time zones, and helped modernize legacy code into future-ready platforms.

I specialize in resilient architectures, observability, and open source tools — with hands-on experience in Java, Kubernetes, Cassandra, and more.

From tech talks to production pipelines, my work bridges deep technical knowledge with a passion for teaching and community impact.

🚀 Currently: Principal Software Engineer in Finland — mentoring teams, designing scalable systems, and speaking on topics that matter.
