About

Detail-oriented Software Engineer with 6+ years building and validating backend systems, RESTful APIs, and cross-platform mobile applications for fintech, healthcare, and government platforms. Deep hands-on familiarity with the systems under test — API contracts, authentication and authorization layers, database performance, and third-party SDK integrations — gives a strong foundation for identifying edge cases, security gaps, and data-integrity issues others might miss. Experienced in code review, defect triage, and enforcing coding and data-validation standards across engineering teams.

EC-Council certified in SQL Injection Prevention, with practical experience testing and securing financial and health data systems. Looking to bring this quality-first mindset to a dedicated Quality Assurance role.
