At Periferia IT-Group, I designed and implemented Aval Pay Center’s AWS payments datalake, processing historical P2M, P2P, and collection data. I built Java 21 Lambda flows and AWS Glue jobs to process payments and make the information available for historical queries.
For Bancamía, I participated in developing Java 17 and Micronaut backend microservices for P2P payments, integrating Redeban APIs and bank SOAP services. I also implemented idempotency and concurrency controls for critical debit and credit operations.
At Carroya.com, I implemented Node.js and TypeScript microservices on AWS, with asynchronous messaging, DynamoDB persistence, and Step Functions orchestration. Earlier at Capgemini, I contributed to Java and Oracle systems for Davivienda and Banagrario, including SOAP web services and APIs.
