What I'm looking for

I'm looking to build scalable, high-performance web or mobile products where I can apply full-stack, cloud-native, API, and CI/CD experience to deliver secure, high-impact digital platforms.

I've built full-stack financial platforms at MassMutual, including FinPlan and SoloK, using React.js, Node.js, MongoDB, NestJS, and PostgreSQL. My work focuses on secure workflows, transaction integrity, payment integrations, and responsive high-volume systems.

At GlobalLogic for Verizon, I developed micro-frontend e-commerce applications with React.js, Next.js, TypeScript, Node.js, SSR, Java microservices, and Elasticsearch. I improved page load times by 30%, reduced production bug-resolution time by 25%, and shortened feature delivery by 40% through CI/CD automation.

Previously at TCS and Aguila IT Consulting, I delivered reusable React interfaces, REST APIs, MERN applications, authentication modules, and role-based access controls. I've increased automated test coverage beyond 85%, reduced API response times by 20%, and mentored junior developers on frontend and API integration practices.

I also build products across fantasy sports, EdTech, financial administration, inventory management, and e-commerce. My toolkit spans cloud-native delivery on AWS, GCP, and Azure alongside GraphQL, Docker, testing, monitoring, and modern deployment pipelines.
