Selected work

Products I designed and built at a recruiting platform used by thousands of companies in LATAM.

AI prescreening

A WhatsApp bot that screens candidates and books interviews

LLM-driven conversation that checks salary, location and experience against the job, then schedules with the recruiter. Weekly interview bookings went up 4x.

Search and matching

Candidate search and job matching over 500K+ profiles

New search engine plus resume extraction from PDFs, cutting recruiter search time by half. A matching pipeline ranks candidates for every open job.

Platform

From an MVP to a cloud platform with CI/CD

Owned the architecture and database from day one, with schema migrations done live as the user base grew from hundreds to thousands of companies.
