What I'm looking for

I'm looking to build scalable, reliable backend products where I can design microservices, event-driven systems, and cloud-native solutions while collaborating closely with product and engineering teams.

I've built backend services for Kavak's high-traffic vehicle auction platform and AstroPay's fintech products, delivering scalable microservices, REST APIs, and event-driven workflows.

At AstroPay, I led International Banking Account and Peruvian CCI account integrations, supporting account creation, transfers, payments, reconciliation, and webhooks. I also designed Send Funds to Non-User via WhatsApp and fraud-prevention APIs for automated transaction decisions.

I work with Java, Spring Boot, Micronaut, Kafka, AWS, PostgreSQL, and MySQL, with a focus on reliable systems, performance improvements, automated testing, and production incident resolution.
