DevOps and release engineer focused on compliant deployments, application support, and problem-solving in high-stakes banking systems.
United StatesWhat I'm looking for
I’m a detail-oriented computer science graduate with about 5 years of diverse experience across sales, customer service, and IT, and I focus on turning complex problems into reliable systems. I’m especially drawn to roles that blend strong technical execution with clear communication and user support.
At Fiserv, I’ve worked within the DNA platform to help ensure the reliability, accuracy, and performance of core banking applications that support deposits, loans, transactions, and integrations. I validate system functionality in a highly regulated environment to help maintain quality standards, while staying focused on accuracy, performance, and risk reduction.
In my Build & Release / DevOps Engineer role, I coordinate, execute, and support software release and deployment activities across enterprise systems. I ensure timely, accurate, and compliant production releases through change management and deployment procedures, monitor deployments, validate release success, document outcomes, and support rollback or incident response when needed.
Beyond operations, I bring application support, software development, and UX skills, and I’ve created technical user guides (1–3 guides). With a TestOut PC Pro certification and a track record of customer-facing work, I bring a practical, service-minded approach to troubleshooting, release readiness, and stakeholder collaboration.
