Summary
🤩
Rockstar🎓
Top SchoolRobbert Van Der Helm is a Haskell software engineer based in Utrecht with 12 years of professional experience building reliable back-end systems and audio tooling. Currently at Channable, he combines strong functional programming skills with a practical systems mindset honed over a long full‑stack stint at ZZindi. His open-source footprint spans low‑latency audio and Linux infra—contributions to PipeWire, Mixxx and audio plugin frameworks (CLAP/VST3/nih-plug) show deep expertise in realtime scheduling, buffer handling and cross‑platform ABI issues. He also contributes to GUI and high‑performance computing projects in Rust and Haskell (vizia, accelerate), demonstrating fluency across languages and FFI pain points. Notably, he fixes subtle correctness and concurrency bugs (filesystem ops, memory expand semantics) and improves observability through better logging and exception handling. With an MSc in Computing Science from Universiteit Utrecht, he pairs academic rigor with hands‑on engineering across audio, systems and language tooling.

Audio Plugin API
Role in this project:Back-end Developer
Back-end DeveloperContributions:104 reviews, 15 commits, 6 PRs in 8 months
Contributions summary:Robbert focused on enhancing the core API structure for the audio plugin. They addressed code inconsistencies, corrected function references, and implemented features related to state context management, including defining the CLAP_ABI macro for calling conventions. Further work included the application of the CLAP_ABI calling convention across various plugin interfaces to resolve issues. This work is crucial for the plugin's cross-platform compatibility and correct functionality.
