United Arab EmiratesWhat I'm looking for
I’m a results-driven Full Stack Developer and Software Architect with 10+ years of experience designing and delivering secure, high-performance web applications across banking, e-commerce, and emergency services (Fire/EMS). In my work, I focus on measurable impact—improving query performance, strengthening reliability, and raising user satisfaction.
Most recently at First Due, I reduced database query execution time by 35% (35–40% faster critical report load times) and rebuilt emergency team UIs with Vue.js, delivering a 25% increase in user satisfaction and a 50% reduction in front-end errors. Earlier, at XETID, I designed security architecture using AlienVault USM and OWASP best practices, achieving zero data breaches over multiple years, and I eliminated production bugs by 60% by mentoring a team of 5 through code reviews and pair programming.
