What I'm looking for

I’m looking for a role where I can own scalable frontend and cross-platform features, build React/Angular web and React Native/PWA experiences, and keep improving performance with clean UI components and reliable testing.

I’m a Software Engineer who loves turning complex product requirements into fast, scalable user experiences across web and mobile. I enjoy building with strong frontend architecture, thoughtful state management, and performance-focused UI.

At Dream11, I built an interactive marquee player to boost engagement and created a React Native POC to ensure smooth iOS and Android performance. I also delivered the Dream11 login flow, supported OAuth sign-in (Google and Apple), and used AI to generate an AI-based profile including photo generation from a user’s picture.

At BluSmart Mobility, I developed a job card management PWA used by 5,000+ users with fast, offline-first behavior. I led a frontend redesign across 3 microservices, built a scalable UI component library with Storybook, delivered 40+ user-facing components, and reduced technical debt through refactoring while optimizing load times.

Earlier, I built feature-rich Angular applications using NGRX and unit testing, integrating new technologies to improve product performance. I also led web and desktop work from scratch, including an Angular + Electron cross-platform issue tracking system for LG, and I’m motivated by continuous improvement, problem-solving, and clean, maintainable code.
