What I'm looking for

I’m looking to drive innovation and scalable architectures in fast-paced, cloud-enabled environments, partnering with product and design teams to build secure, high-performance applications through strong engineering standards and Agile delivery.

I build scalable, high-performance web applications, most recently at Deloitte using Next.js, React, TypeScript, and MongoDB to support large user bases.

At Deloitte, I led architecture discussions for shared platform components to improve modularity and reusability across multiple products.

I’ve shipped real-time functionality by optimizing backend data models and APIs to decrease latency, and I’ve enhanced scalability and performance through microservices architecture and caching strategies.

I also mentored junior developers, ran code reviews, and helped establish testing, debugging, and documentation best practices. Earlier, at Infosys, I developed React/TypeScript/Node.js applications, built RESTful APIs, and supported deployments with Docker and Kubernetes in Agile sprints.
