πŸ‘‹ Hi, I'm David

Software engineer focused on AI-adjacent products β€” voice agent orchestration, browser automation, and full-stack systems that ship to real users. B.S. Computer Science & Data Science, Saint Mary's College of California ('25).


πŸ› οΈ What I've Built in Production

Forward Deployed Engineer β€” Spoqen (founding technical hire) Built Playwright-driven browser automation against a third-party system with no public API, and orchestrated Vapi voice agents directly on live customer systems. No existing playbook β€” designed the approach from scratch.

Human-in-the-Loop Engineer β€” Infinitus Monitored live production voice agent calls in real time, catching hallucinations and logic drift before they reached customers, and surfaced recurring failure patterns back to the engineering team.
