Hello, I am Skinner. Senior Backend Engineer with 11+ years building reliability-critical, real-time distributed systems. Co-founder & former CTO, now back on a hands-on IC track by choice.

Alongside this, I'm actively building two personal projects: Vox Personalis, a fine-tuned ASR for Deaf-accented speech, and an On-Device ASR with Speaker Diarization.

Looking for: Senior Backend / Senior Software Engineer roles. Open across stages (startup to established), with a lean toward real-time, distributed, or Applied AI systems.
