Senior software engineer specializing in scalable React + TypeScript frontends, micro-frontends, performance, and automated testing.
IndiaWhat I'm looking for
I’m a Senior Software Engineer with 8 years of experience building scalable React.js and TypeScript frontend applications for enterprise platforms. I focus on frontend architecture, micro-frontends, and Redux-based state management to turn complex requirements into reliable, high-performance user experiences.
At CGI (Apr 2023–Present), I’ve built modular React + TypeScript modules using Redux Saga to accelerate feature delivery by 30% across sprint cycles. I designed reusable UI patterns, reduced duplicate code by 25–30%, and improved initial page load performance by 40% on low-bandwidth networks through code-splitting and lazy-loading.
I also strengthened quality and resilience by integrating Jest and React Testing Library with CI/CD quality gates via GitHub Actions, cutting production regressions by 30%. Previously at EPAM Systems, I delivered micro-frontends and improved WCAG AA accessibility, and at Byond Travel I lifted Lighthouse scores from 68% to 92% while shipping Next.js and PWA experiences—always supported by strong code reviews, performance tuning, and mentoring.
