What I'm looking for

I’m looking for a team that values modern architecture—micro-frontends, serverless on AWS, and DevOps automation—so I can reduce cost, improve performance, and lead cross-functional delivery.

I’m a senior full stack engineer with 9+ years of experience, focused on modernizing legacy systems into Serverless and Micro-Frontend architectures. I bridge development and operations by implementing AWS Cloud Native solutions and DevOps automation.

At Cognizant, I spearheaded the migration of a massive monolithic Angular application into a Micro-Frontend architecture using Webpack Module Federation, reducing release conflicts by 60%. I also led the transition of core backend services to AWS Lambda, optimizing scalability and reducing cloud spend.

I build high-impact UI and platform capabilities, including a proprietary UI library that replaced rigid third-party packages for better flexibility and performance. I enhanced OpenSearch accessibility by integrating it securely into the application layer, replacing manual port-forwarding methods.

Previously, at MetLife Global Operations, I led legacy modernization by refactoring jQuery codebases into modular Angular components to improve maintainability. I engineered responsive portals with RxJS for complex state management and built complex reactive forms with custom validators, while mentoring junior developers and enforcing ESLint/Prettier standards.
