## Cases

- [LLM systems in production](https://matheuspavaneli.github.io/portfolio/en/#case-orchestration): The company's first AI feature, built so no single vendor can take it down
- [rag-eval](https://matheuspavaneli.github.io/portfolio/en/#case-rageval): Whether the answer came from the right passage, measured before anything was tuned
- [The two-second query](https://matheuspavaneli.github.io/portfolio/en/#case-query): The planner was not slow. Its statistics were stale.
- [Seal](https://matheuspavaneli.github.io/portfolio/en/#case-seal): Approval-as-an-API: human-in-the-loop as infrastructure, not as a code change
- [Nanquim](https://matheuspavaneli.github.io/portfolio/en/#case-nanquim): The Brazilian market ships backend SDKs in seven languages and stops at the browser
- [Anchor](https://matheuspavaneli.github.io/portfolio/en/#case-anchor): Churn is visible in the ad accounts weeks before anybody cancels
- [technology-art](https://matheuspavaneli.github.io/portfolio/en/#case-artefacts): Eight artefacts, 3.3 million years, one point cloud reassembled into each of them
- [The abandoned dashboard](https://matheuspavaneli.github.io/portfolio/en/#case-dashboard): Inherited with no handoff, no documentation, and numbers the business was already deciding on
- [The 1.9 GB image](https://matheuspavaneli.github.io/portfolio/en/#case-image): Nobody had documented why it was that big, so the first job was finding out
