Strengthen DevSecOps practices by partnering with platform engineering to enhance CI/CD pipelines (e.g., Flosum, Gearset, Git), automated testing, static code analysis, and release governance across multi-sandbox landscapes.
Serve as a multiplier and mentor by providing technology guidance to junior developers and coaching senior engineers; lead architecture guilds, brown bags, and pattern reviews to uplift delivery velocity and quality.
