Profile
Industrial engineering student working as a generalist project engineer: as much at home on a structural job or the design of a heat engine as on the front end of a SaaS or the statistics of a quant engine. Designed and built Ottometrix end to end, from the data pipeline to the product.

- Validated it with pre-registered tests and a one-shot holdout; reverted the only change that failed out of sample.
- Built the SaaS: screener, stock file and portfolio X-ray (Next.js, TypeScript).
