Summary: Senior Software Engineer with 12 years of experience. The last five at Mercado Libre (120M+ active buyers, 18 countries), working on marketplace and logistics platforms. Previously at Softplan, where I migrated a large Java monolith to Go microservices. Mostly Go, some Java, all of it distributed and none of it allowed to go down.
A few things I've built there:
- Led the technical design of the event-driven orchestration behind the marketplace's virtual try-on feature. Go services coordinating an async image-generation pipeline (Python + GenAI) behind a React experience, running at marketplace scale. Roughly 7% conversion lift in the fashion vertical.
- Built the Go integration platform that launched a new digital-goods category (gift cards, digital games) across several LatAm countries. Thousands of orders a day against third-party partner APIs, where every vendor implements the same spec slightly differently and every failed call is somebody's money. Idempotency and reconciliation were the whole job.
- Built event-sourced Go services in the logistics platform, running across the LatAm fulfillment network. The valuable part wasn't the write path. It was making delivery workflows reconstructible after the fact, so incidents became answerable questions instead of archaeology.
Looking for Senior/Staff roles focused on distributed systems, platform, infra, payments, marketplaces, anything where correctness under load is the hard part. Open to full-time or contract.
