Principal Frontend & System Engineer

Staff-level frontend/system engineer with 20+ years of experience in shipping performance-critical, real-time, and composable interfaces. Expertise includes UI architecture, latency-aware design, composable systems, fast iteration, and taking projects from prototype to production. Has worked on custom poker clients, in-house game engines, embedded media platforms, large-scale e-commerce widgets, and LLM-assisted pipelines and tooling. Recent personal projects include a local-first genealogy tool (Socken), a cultural site with CMS and live video workflows (Kolibri Club), and a media archiver (grabfilm). Seeking small, focused teams working on tools, infrastructure, creative software, or low-latency systems, preferring high agency, low management overhead, and no hype-driven development. Open to consulting, contracting, or embedded long-term roles.
