Projects
Side projects. None of these are products — they are things I built to learn something or scratch my own itch.
Featured
Personal project exploring multi-agent orchestration. The use case is sales-call review; the actual point was learning Anthropic tool use, prompt caching, and persisted agent state.
Personal project exploring real-time voice AI. The use case is a clinic receptionist; the actual point was hitting a sub-second user-perceived latency budget with full per-leg instrumentation.
Personal project exploring agentic RAG. Every answer is grounded by inline citations; clicking one opens the source document at the exact region that produced it.
Personal project — recurring-billing scaffolding for local service businesses. Built as an excuse to learn Nx, AWS CDK, and the boring billing layer end to end.
