Software Engineer at Amigo Tech who extracted a Node.js reconciliation engine into a TypeScript microservice, cutting processing time from ~12s to ~3s.
BrazilWhat I'm looking for
At Amigo Tech, I extracted the bank reconciliation engine from a legacy Node.js codebase into a dedicated TypeScript/NestJS microservice. I owned the cutover and test strategy, bringing average processing time from ~12s to ~3s under production data volume.
I also improved a slow insurance receivables export from ~90s to ~15s with data modeling changes, PostgreSQL indexes, and bounded parallel processing. I developed a shared NestJS REST API that generates medical claims in the XML and PDF formats required by Brazil's TISS/ANS standard, making document generation ~50% faster.
Earlier at Amigo Tech, I delivered open banking reconciliation end to end and developed full-stack cash management features and foundations for an in-house payments product. I work across backend and product delivery, using Node.js, TypeScript, and PostgreSQL.
