At Doji, I built an event-driven payout module for PIX and bank transfers, with idempotent handling, retries, and webhook-based reconciliation. I also developed an accounts-receivable module and Omie ERP integration to automate fiscal service orders and payment calculations.
I migrated Doji’s API surface across 13 repositories to a unified, JWT-authenticated Kong API Gateway, completing the production cutover without customer-facing downtime. I also moved staging and production from GKE Autopilot to Standard clusters.
At Transfeera, I designed a PIX reconciliation pipeline that processes around 1 million records daily. By moving heavy queries to BigQuery, I reduced processing time from over 30 minutes to under 5 minutes.
I also applied the Outbox pattern to improve reliable event delivery and built ledger capabilities for double-entry accounting. Earlier, I built and maintained backend features for Mova’s Credit-as-a-Service product.
