30+ endpoints
Migrated from AWS Lambda into a Node.js backend while feature development continued.
Senior Software Engineer · Brazil (UTC-3)
I build backend systems and products that small teams can rely on.
My work spans backend architecture, cloud infrastructure, and pragmatic full-stack product engineering—from technical planning through production.
I'm available for remote senior and staff-level contract roles, as well as relevant projects.
About
Pragmatic engineering for small, ambitious teams.
I have 11+ years of software experience, including the last five working remotely as a contractor for startups in the US and Europe.
My strongest work sits at the intersection of backend architecture, technical planning, and product execution. I'm drawn to problems where the hard part is not just writing code, but sequencing the work, clarifying tradeoffs, and reducing operational risk.
The goal is always the same: turn messy product requirements into systems a small team can realistically build, operate, and maintain.
