At ACT DIGITAL, I contributed to modernizing Fiserv’s payment processing platform, updating Java from version 8 to 25 and evolving services toward Kafka-based, event-driven communication. I also implemented observability with OpenTelemetry and helped develop a payment-processing fallback mechanism.
At ADASTRACORPORATION, I developed Java and Spring Boot applications for Deutsche Börse’s client onboarding and financial data processing. My work included REST APIs, integrations with financial systems, and automated tests supporting reliability and regulatory requirements.
At TQI, I participated in building PagBank’s microservices-based banking platform, including services for transfers, billing, and digital accounts. I helped improve observability, contributing to an approximately 30% reduction in incident resolution time.
