What I'm looking for

I'm looking for a Backend or Full-Stack Engineer role with real ownership of production services, where I can build secure APIs, reliable deployments, and AI-powered application features.

I'm currently building backend systems at The Watermark Co for healthcare, e-commerce, and local-business products, taking REST APIs from schema design to production on Node.js, Express.js, and MongoDB. I secure production services with JWT, role-based access control, reusable middleware, and Docker deployments on AWS EC2 behind Nginx.

Previously, I built enterprise workflows and Angular dashboards at AutomatEazy, and delivered Node.js, MongoDB, PostgreSQL, Redis, Jenkins, and React solutions for client applications at The Web Agency. I also integrate OpenAI APIs for AI-powered product features, including structured outputs, function calling, and prompt engineering.

Outside client work, I'm leading full-stack development for People for Animals Gurgaon’s official website and built an AI-powered skincare routine recommender. I was named Developer of the Year for technical ownership across multiple client projects.
