# Projects

Side projects. None of these are products — they are things I built to learn something or scratch my own itch.

## Featured

- [Sonar](https://picoral.me/projects/sonar) — 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 end to end.
- [Relay](https://picoral.me/projects/relay) — 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.
- [Cite](https://picoral.me/projects/cite) — 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, and an automated judge scores whether the source actually supports the claim.
- [Forge](https://picoral.me/projects/forge) — Personal project - measured vLLM serving benchmark for Llama 3.1 8B on a RunPod A5000, with BF16 at 2,169 total tok/s, $0.035 per 1M tokens, and AWQ retaining 99.4% mean quality.
- [Anvil](https://picoral.me/projects/anvil) — Personal project - completed QLoRA fine-tuning of Llama 3.1 8B on synthetic contract extraction, with 100% JSON validity, $58.46 measured run cost, and a 0.80M-token monthly breakeven model.
- [QuotaHit](https://picoral.me/projects/quotahit) — A shipped SaaS for Brazil's solo field-sales reps — find companies to visit, build the day's route with live traffic and fuel cost, and turn a post-visit WhatsApp voice note into a confirmed record.
- [Desvia](https://picoral.me/projects/desvia) — A driving-navigation app for Brazil (iOS and Android) whose difference is private map areas you draw to avoid when possible or never enter — with real-time traffic and turn-by-turn on top.

## Other work

- [Recurra](https://picoral.me/projects/recurra) — 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.
