Senior software engineer at ConnectPoint building Redispatch 2.0 and shared tools for energy software teams.

Poland

Message

At ConnectPoint, I built the full-stack Redispatch 2.0 platform for Stadtwerke Leipzig, connecting Spring Boot services and Kafka-based event processing to Angular dashboards used by grid and power plant operators. I also worked on telemetry data deduplication and time-series storage in TimescaleDB.

I led the migration of several projects to an Nx monorepo, enabling one codebase to serve five clients, and co-created an Angular Material and Storybook component library used by six teams. I guided a team of five developers at peak and advised the client on architecture and roadmap.

I defined a repeatable workflow for AI-assisted development with human review and verification, packaged as custom Claude Code skills. Earlier, I built developer tools and applications for Flexys Solutions Ltd, Strefa Przemian, and the University of Warsaw, and worked on Angular and mobile applications at Efinity.
