What I'm looking for

I'm looking to continue owning end-to-end enterprise application work, collaborating with product and QA teams, improving release quality, and solving cross-layer frontend, backend, API, and data problems.

I've built and supported enterprise web applications at Early Warning Services and through a Motion Recruitment client assignment, delivering coordinated React, TypeScript, Java, Spring Boot, REST API, and PostgreSQL changes.

I trace workflows from UI behavior through service logic and persistence, strengthen validation and error handling, and resolve stale records, duplicate data, API failures, and production defects. I turn reproduced issues into automated regression coverage with Jest, JUnit, integration testing, UAT, and release verification.

I work closely with product, QA, design, platform, and engineering teams to clarify acceptance criteria, evolve API contracts safely, and ship reliable end-to-end changes.
