Rockstar🎓
Top SchoolUldis Barbans is a Principal Software Engineer with 13+ years building and operating large-scale data and backend systems, currently shaping cloud-based geospatial solutions at Leica Geosystems in Stockholm. He blends deep algorithmic and systems knowledge with hands-on work across Java, Python, C++, SQL and cloud-native tooling to deliver pragmatic, maintainable and cost-effective software. At Spotify he architected and ran data ingestion and scheduling pipelines (contributing to the popular Luigi workflow project) and later re-architected critical data pipelines at Capchase to scale on Google Cloud. Uldis drives DevOps adoption, CI/CD and test automation to speed delivery and improve reliability while mentoring teams on ownership and best practices. He is comfortable across the full stack and operations — from low-level C and embedded systems to Kubernetes, BigQuery and distributed dataflow frameworks — and enjoys turning messy legacy systems into observable, automatable platforms. Colleagues rely on him for clear communication, pragmatic trade-offs and a continual appetite for technical improvement.
