What I'm looking for

I’m looking to keep leading end-to-end delivery—architecting RESTful APIs, optimizing performance and deployments, and mentoring teams—while building scalable web applications with Node.js, React, and reliable data layers.

I lead end-to-end development of scalable web applications at Infineit Global Services LLP, using Node.js, React.js, Sails.js, and PostgreSQL. I mentor developers through code reviews and technical guidance, and help manage deployments and production issue resolution in Agile.

Before that, I led a team of 10 developers at Sarvadhi solution Pvt Ltd, delivering MERN applications and driving performance and efficiency improvements by 40%. I also migrated a 150+ GB production PostgreSQL database with minimal downtime to improve scalability and reliability.

Earlier, at Crest info systems Pvt Ltd, I built reusable React components and RESTful APIs with Node.js for enterprise clients. I integrated third-party services like Facebook Marketing API, Google Maps API, and payment gateways to ship production-ready features.

Across projects, I’ve worked on a real-time cab booking platform with MQTT, an AI content and Facebook Ads management platform, an affiliate platform connected to Shopify API with Socket.io, and an ERP for the diamond industry using Redis caching and database query optimization.
