What I'm looking for

I'm looking to build high-performance, scalable web applications where I can lead products from conception through deployment, improve user engagement, and contribute to mission-oriented teams.

I've built and scaled web platforms at C2FO, Infoedge India, Warwick Business School, and Warwick Manufacturing Group, from public-facing pages to internal portals and research dashboards.

At Infoedge India, I led the migration of 99acres.com to React.js, increasing conversion by 40% across 12.9 million monthly users. At C2FO, I launched C2TReDs, a WCAG-compliant platform helping SMEs auction government-authorised trade receivables to financiers.

I also engineered a predictive data tool using Python, Nest.js, PostgreSQL, and AWS S3 to turn historical data into real-time visualisations. Earlier, I built SALT, a JavaScript, Pixi.js, and Node.js gaming app that reached more than 400,000 organic downloads.

I'm focused on high-performance React and Next.js architectures, taking products from database design and API integration through cloud deployment. I bring experience with TypeScript, Node.js, AWS, Docker, Kubernetes, testing, and Agile delivery.
