About
Who I am
I'm a full-stack software engineer with 5+ years in production systems. I work across the stack — React and Next.js on the front end, Node.js and NestJS with relational databases behind them — and I'm strongest in domains where correctness is not negotiable: payments, banking and compliance integrations, and background processing that has to survive retries.
I build microservices and serverless backends on AWS, and I care most about what happens after launch — clear service boundaries, tests that catch real regressions, and code the next person can pick up without a meeting. I lead and mentor developers alongside the engineering work.
Brazilian and Portuguese citizen, fluent in English.

Personal
Split The Party
Solo — product, design, front end, back end and infrastructure
A web app for settling shared expenses in a group. Participants and costs go in, each item is assigned to the people it actually applies to, and the app resolves the debts into the smallest possible set of transfers. The free tier runs entirely in the browser with local storage; the paid tier adds server-side persistence and sharing per event. Built in Portuguese and English, and I own every part of it — product decisions, interface, back end and infrastructure.

Software Engineer
Fintech platform handling invoices and digital wallets. I design and build the microservices behind it — banking API and compliance integrations in NestJS, and background job processing for webhook handling. I also contributed to a full interface redesign in React, and I lead and mentor two developers on the team.
