Message

At Infisical, I rewrote a single-tenant proof of concept into a multi-tenant Go and Postgres secrets API, then put it into production for hundreds of teams. I also wrote a Kubernetes secrets sync agent and built React TypeScript pages for team secret management and access requests.

At Thoughtworks, I built a Spring Boot payment reconciliation service that processed about 50k events per hour, along with settlement and webhook recovery flows. Earlier at CI&T, I implemented Java REST endpoints and Python ETL jobs, including an import that reduced one client’s manual corrections from daily to weekly.
