At Acceso, I architected and built a production multi-tenant SaaS event ticketing platform as the sole engineer, designer, and product owner. I integrated Stripe and Azul payments, then added signed QR tickets and offline-capable check-in scanning.

At Thryv, I design API test strategies for microservices and validate event-driven workflows using AWS SQS/SNS. Previously, at Neural Technologies Solution SRL, I built automated test suites and test plans for RESTful and GraphQL endpoints.
