Rockstar🎓
Top SchoolNick Donaldson is a Lead DSP Engineer and entrepreneur with 13 years of experience building music technology, audio DSP, iOS apps, and embedded firmware. He runs Infrasonic Audio, shipping Eurorack products and contracting on full firmware and hardware designs, while also leading DSP at William Mathewson Devices. Nick has a strong mobile background—driving iOS architecture and CI practices at companies like BetterUp and iZotope—and has contributed to notable open-source audio and testing projects such as Novocaine and OHHTTPStubs. His work blends low-level C/C++ audio performance with modern Swift/SwiftUI app development and pragmatic testing strategies. Trained as an electrical engineer with an M.A. in Music Technology from McGill, he brings both formal DSP research grounding and hands-on hardware experience to music-tech product development. A less obvious strength is his track record of improving testability and long-term maintainability in existing codebases while shipping creative audio products.
