I'm a backend engineer with 8+ years of experience building distributed systems — APIs, event pipelines, and the unglamorous plumbing that keeps them reliable: outboxes, job queues, message buses, and the occasional 3am incident. Go is my primary tool; I reach for Node.js (NestJS/Express) when the ecosystem calls for it, and I'm comfortable across PostgreSQL, MongoDB, Redis, and Neo4j, deployed on AWS/GCP with Docker, Kubernetes, and Terraform.
🔭 Domains I gravitate toward: distributed systems & event-driven architecture, data-intensive backend platforms, fintech & payments infrastructure, and developer tooling & observability.
🎸 Outside of code, I play guitar and lose hours to linguistics — how languages encode meaning, why some grammars agglutinate and others don't, that sort of thing. Currently teaching myself Spanish and Portuguese for fun — badly, but happily. Turns out grammar is just another system to reverse-engineer.
