At aoi.rs, I sustained 20K RPS with zero failures and a 35 ms P99 response time in a Rust URL redirection service, using DynamoDB lookups and CloudFront edge caching.
I also reduced dashboard API calls across 80% of read flows with a local-first architecture, serving data from IndexedDB and reconciling it with incremental server deltas.
At Cooud, I designed and built Stripe Connect payment infrastructure for customer payments, refunds, and seller payouts. The marketplace processed more than R$1 million in sales, with a peak of R$60,000 in one day.
At Cooud, I developed TypeScript and Rust microservices and event-driven payment flows with RabbitMQ. Earlier, as a freelance Frontend Software Engineer at Maxbot, I contributed to migrating its customer support platform from PHP to Next.js and React and implemented real-time messaging with WebSockets.
