Guilherme Bonfim
Software Engineer at Mercado Livre
São Paulo, Brazil
Summary
🤩
Rockstar🎓
Top SchoolGuilherme Bonfim is a software engineer based in São Paulo with four years of experience building both front-end experiences and back-end microservices for high-scale products at Mercado Livre. He currently architects and maintains Java/Spring Boot services for the Mercado Pago Resellers Program across four Latin American markets, tackling complex reward state machines, batch jobs in BigQuery, and payment integrations. Earlier roles show a strong front-end pedigree—creating interactive SVG maps and a no-code drag-and-drop landing page builder—so he comfortably spans from React UIs to Kotlin/Java backend systems. Guilherme has delivered cross-market, backward-compatible migrations and reworked core rewards and level-progression models under tight deadlines, demonstrating product-aware engineering. He pairs practical DevOps observability (DataDog, Grafana) with data-driven batch processing, and his GitHub persona as a "Summer Jobber" hints at a pragmatic, hands-on approach to learning and shipping features.
