01 / About

At Latvijas dzelzceļš I lead the company's Node.js web systems - designing and maintaining services, integrating new applications with legacy infrastructure, building RESTful APIs, and running containerized CI/CD pipelines.

I also own the company's Scala/JVM and .NET product - planning its roadmap and deciding what gets built next - and serve as an internship supervisor, mentoring a junior developer hands-on.

Background spans full-stack product work (Mitigate) and long-running internal systems (MikroTik), across Node, React, Ruby, and TypeScript.

Much of my best work lives in private repositories - find me on GitHub or LinkedIn.
