What I'm looking for

I’m looking for a frontend role where I can build responsive, accessible user experiences with React/Angular, partner closely with backend and cloud teams, and continuously improve performance and code quality in an Agile environment.

I’m a Master’s-level Frontend Developer with a strong track record of building responsive, user-focused web applications. I’m passionate about clean code, performance, and user experience, and I bring a solid foundation in UI/UX design principles.

At Virtusa Pvt. Ltd., I engineered user-facing dashboard features that aggregated data from AWS, Azure, and GCP. I implemented frontend logic for asynchronous data handling and partial page updates to improve application responsiveness, while ensuring code quality through unit testing and frontend best practices.

Previously, at Mainframe Pvt. Ltd., I developed highly responsive and reusable UI components with Angular and modern JavaScript, partnering with backend engineers to integrate APIs seamlessly. I also bring a design-forward perspective from my UI/UX-focused role at Dsquare Technologies Pvt. Ltd., where I delivered accessible interactive components, led product demos, and communicated design and technical decisions clearly in Agile environments.
