Senior software engineer from Brazil with 11+ years shipping production software, full stack with a backend focus. I work AI-first every day with Claude Code, backed by specs, tests and CI.

• Fintech at Nubank: worked on the US launch with Clojure, Datomic, Kafka and AWS, including account linking with third-party financial APIs and the transaction model behind ACH transfers.
• AI developer tooling: built an MCP server that lets AI assistants run and evaluate Clojure code, so generated code is validated in real time.
• LLM features in production: as co-founder and CTO of a SaaS product with 1,000+ users, shipped a pipeline that turns WhatsApp support messages into structured helpdesk tickets, plus video call transcription and summaries.
• Multi-agent engineering: coordinated parallel Claude Code agents through a shared ledger and webhooks to keep communication between agents cheap and consistent.

Most of my work lives in private company repositories. Happy to walk through any of it in an interview.
