About Brijesh Kumar

I’m a seasoned Mobile & Front-End Engineer with 7.5 + years of experience designing, building and delivering scalable, user-centric applications across iOS, Android and web. I thrive at the crossroads of native and cross-platform development, working extensively with React Native, ReactJS and native Android (Kotlin/Java), and leveraging tools like GraphQL, Firebase, CI/CD pipelines, and modern DevOps and testing practices.Over the years, I’ve contributed end-to-end to diverse projects — from retail e-commerce apps and social-security portals to secure financial and enterprise-grade applications. I’ve helped launch cross-platform mobile apps, built multilingual web portals, integrated advanced features like push-notifications, analytics, and in-app reviews, and optimized performance and developer workflows. I believe in delivering solutions that are not only functional, but performant, maintainable and built for scalability.What sets me apart is a strong sense of ownership and craftsmanship — I’m equally comfortable with architecture and implementation, collaborating with stakeholders and designers, mentoring team members, or diving into debugging and performance tuning. I’m passionate about clean code, seamless user experience, and delivering high-quality products on schedule.I’m always open to new challenges: whether it’s building a green-field mobile app, improving an existing product’s performance, or collaborating on frontend + backend integrations. If you’re seeking a developer who bridges mobile, web and native with a delivery mindset — feel free to connect.
