Location: São Paulo, Brazil (UTC-3)
Remote: Yes (remote only today, 8+ years on distributed teams across US and EU timezones)
Willing to relocate: Yes, with visa sponsorship
Visa: Brazilian citizen. I hold a US B1/B2 for occasional travel (not work
authorization), so relocation would require sponsorship.

Senior backend engineer, 8+ years, currently at Globant embedded with client
teams. Last 15 months on Riot Games' player support platform, owning backend
integrations on a GraphQL gateway that fans out to 85 services behind League
of Legends, VALORANT, TFT, Wild Rift and 2XKO. Before that, two years on
Point72's trading systems (Drools rules engine, OpenShift cluster migrations),
and backend for OneSpan, EDP Portugal (Quarkus/Kafka) and SulAmérica.
On my own time I built and shipped a travel product end to end, solo:
https://ondviajar.com.br/en/ - Flutter client in 10 languages on both app
stores, Spring Boot backend on ECS Fargate, and a conversational LLM agent
with tool calling and voice that turns one chat into a full itinerary, plus
the CI/CD, payments and CRM plumbing around it. Anthropic Claude Certified
Architect (Foundations); also Oracle Java SE 8/11, Spring Professional,
AWS SAA and ML Specialty, GCP ACE.
Open to backend or AI/LLM engineering roles, contract or full-time.
