What I'm looking for

I seek a senior engineering role building scalable, user-centered web applications with strong testing, CI/CD, and cloud integration in collaborative, product-focused teams.

I am a Senior Software Engineer with 12 years of experience designing and delivering scalable, high-performance user interfaces using Java, Spring Boot, React, Angular, Node.js and modern frontend technologies.

I have led front-end architecture discussions, implemented testing and CI/CD practices that improved reliability by 40% and reduced API response times by 30%, and built interactive dashboards for AI/ML applications.

I collaborate closely with cross-functional teams and designers to translate requirements into intuitive, responsive, and accessible applications while driving continuous improvement and operational efficiency through automation and cloud integrations.
