At Guidehouse, I led the architecture, prototype, and full-stack delivery of secure supervisor email recertification across Java/Spring Boot, Angular, APIs, and PostgreSQL. The client estimated the workflow could save approximately 450 administrative hours annually; that impact is projected, not verified.
I also turned an underdefined audit-reporting epic into a sequenced MVP, defining API and data design, dependencies, and estimates. I built reusable REST foundations and dynamic filtering and sorting for complex reporting grids.
For the recertification feature, I designed token security controls including single-use nonces, hashing, backend validation, and rate limiting. I also resolved a Spring/JPA transaction race condition and validated after-commit behavior with automated tests.
I use Gemini CLI for planning, code review, testing, refactoring, and requirements audits, and created a reusable skill to check Jira story consistency. Earlier at Genesis10, I contributed service-layer, controller, MySQL, and frontend JavaScript work to a contact-tracing and attendance application.
