Things I have built and shipped. Tools meant to be used, not just described.
A service desk that runs on the mail it receives. Inbound messages are read, classified against a taxonomy, scored for risk and priority, and routed to the desk that owns them, then tracked to a close against service-level targets. Cases the classifier is unsure of enter a review queue and are blocked from automatic action until a person releases them.
A permissioned provenance ledger for electronic components. A lot is minted at the fab, changes hands only when both sides sign the same terms, carries its qualification results and environmental history with it, and can be recalled through every descendant lot it ever became. Aimed squarely at the counterfeit and the misrepresented part.
Audio-visual guidance for a lay responder giving CPR with no clinician present, built three separate ways against the same problem: a desktop rig with pose tracking, a phone app reading compressions from the handset accelerometer, and a fork widened to triaged first aid. Guidance is deterministic and everything runs on the device.
Retrieval-augmented search across a document corpus, with every answer cited to the document and page it came from. Embeddings, reranking, the vector store and the model all run on one machine, so nothing leaves it. An answer the corpus cannot support is refused rather than invented.
A supply chain mapping search engine. Enter any public company and Seerandra maps out who supplies it and who buys from it, then lets you keep following those connections outward across the wider market. The result is a clean, fast way to see how companies actually depend on one another, all from a single search.
