Vegard Stikbakke is a software engineer with 10 years’ experience building data-intensive, distributed systems and APIs, currently working remotely from the Stavanger area. He played a key role at Dune as an early engineer, shipping Rust and Go services that replaced large Spark fleets and slashed processing times from days to hours for millions of blockchain SQL views. His work spans data infrastructure (Delta Lake, Apache Arrow, Parquet, DataFusion), backend systems, and SQL tooling—he contributed to and built AST-manipulating migration tools that leverage the popular sqlglot project. Vegard is an active open-source contributor, fixing data definitions in Dune’s Spellbook and improving cross-dialect SQL behavior and shell utilities in notable repos. He pairs an academic background in statistics and mathematics with pragmatic engineering, often automating large migrations and performance wins that aren’t obvious from surface metrics. Based in Bryne, Norway, he combines deep technical curiosity with a track record of shipping production-critical tooling under tight timelines.
