Summary
👤
Senior🎓
Top SchoolFredrik Arvidsson is a Staff Engineer and seasoned software architect with 14+ years building low-latency trading systems, payments platforms and large-scale event-driven architectures across finance and music-tech. He blends deep JVM and systems-level expertise (Java, Kotlin, Scala, Go, C/C++) with cloud-native practices (GCP/AWS, Kubernetes, service mesh) to design resilient microservices and real-time data pipelines that run machine learning in production. A frequent technical leader and mentor, he has shaped engineering strategy at companies from Spotify and Klarna to Utopia Music and Tink, and serves on architectural councils to set company-wide policies. Fredrik is also an active open-source contributor—co-founding the LibrePilot UAV project and committing to OpenJDK—bringing a hardware-to-cloud perspective that surfaces in his work on embedded hardware configuration and performance optimizations. Based in Stockholm, he pairs pragmatic engineering with strategic due diligence and M&A technical assessments, making him equally comfortable in code, architecture reviews, and cross-team leadership.

Contributions summary:Fredrik's commits primarily focus on performance optimizations within the UAV object browser, specifically targeting the reduction of QTimer instances and redraws to improve performance. This involved modifying the highlighting behavior of tree cells to cascade highlights to parent elements and incorporating a HighLightManager to manage highlight expirations. The changes also involved refactoring code to use maps instead of lists and adding more support methods for the arbitrary depth of the UAVO tree. The user contributed to both the backend and frontend aspects of the system by also implementing new wizard layouts and fixing bugs related to color, highlight time and metadata settings.
