At Mastercard Technology, I deliver Java and Spring Boot services and APIs for payment, network, and settlement workflows, strengthening reliability and readiness for critical settlement capabilities.

I built the Settlement Facilitator end-to-end test framework using Java 17, Cucumber BDD, Axon/Kafka, PostgreSQL, Spring Boot, Jackson, and AssertJ. It reduced manual regression effort from days to minutes by automating transaction publishing, database validation, settlement file generation, event validation, and final processing checks.

I've improved validation of asynchronous settlement processing through scheduler-aware UTC trigger-cycle logic, configurable buffer times, configuration-driven topics, and YAML profiles. I also support production through incident triage, root-cause analysis, Dynatrace and Splunk monitoring, documentation, peer reviews, and technical demos.

Earlier, I delivered quality engineering and automation work across Mastercard initiatives and at AFour Technologies, covering functional, regression, smoke, API, and UAT testing. I build reusable frameworks with Java, Selenium, RestAssured, Cucumber, JUnit, and Maven while collaborating on test strategy, traceability, and release confidence.
