What I'm looking for

I'm looking to build and operate reliable product systems where financial correctness, measurable AI performance, and practical end-to-end ownership matter.

I'm building Yupa, a multi-tenant accounting SaaS in technical pilot with micro-businesses, as its sole founding engineer. I own the architecture, delivery, security, and operations across a Rust accounting engine, Python AI service, Node.js authentication service, and React application.

I built Yupa's PCGE-compliant double-entry accounting engine with inventory tracking, multi-currency support, and Peruvian tax reporting. I also shipped a Spanish voice assistant for recording sales, reducing end-to-end voice latency from 9.7 to 6.1 seconds while raising prompt cache hit rates to 97%.

My background in end-to-end accounting under SUNAT, IGV, and PCGE regulations informs the financial correctness I build into software. I operate production infrastructure with Docker, CI/CD, backups, monitoring, and security designed to keep systems reliable without constant supervision.
