What I worked on
Most of my work was on agent runtimes, workflow orchestration, and developer tooling.
I fixed database lifecycle bugs that showed up during Next.js hot reload, which made the framework more stable for people building on it.
I also built a pre- and post-call system. Before a call it writes up a client briefing, and afterward it turns the transcript into a summary, action items, and follow-ups.
