As a Senior Software Engineer with 15+ years of hands-on experience, I excel in building dynamic and responsive web applications using Angular, React, and Node.js. I am passionate about delivering scalable, maintainable solutions with a strong focus on performance, security, and web accessibility. With a proven track record of leading teams and driving successful projects, I bring expertise in TypeScript, Redux, NGRX, React query and automated testing tools like Jest and Cypress.At Cisco, I play a pivotal role as a Senior Software Engineer, leading a team of UI engineers to develop and maintain large-scale front-end applications using React and Angular. I create and review design documents, conduct thorough code reviews, and contribute to architectural decisions. My responsibilities include improving development and release processes, enhancing modularity through NX libraries, and automating API services, while ensuring system reliability through rigorous testing with Jest and Cypress. My focus is on delivering scalable, secure, and high-performance applications, while mentoring junior developers and fostering a collaborative, innovative environment.During my time at Cognizant, I led the development of large-scale single-page applications (SPAs) using Angular and React. As a Tech Lead, I collaborated with cross-functional teams to define technical strategies, design scalable solutions, and improve overall application performance. I was responsible for building responsive, user-friendly interfaces while ensuring that the code adhered to best practices in accessibility and performance standards. One of the projects involved migrating a legacy application to a modern single-page architecture with React, integrating real-time data through a streaming service, which significantly improved the application’s efficiency and user experience. In another project, I applied Angular Universal to deliver server-side rendering, improving performance over slow networks and ensuring compliance with web accessibility standards. My focus was on optimizing the development pipeline through modular design, automated testing, and continuous integration, delivering high-performance solutions in an Agile environment.
