• Led modernization of ONGC's Mumbai intranet — a central system holding all of ONGC's asset data — migrating a legacy PHP application to a full-stack Next.js, Node.js, and PostgreSQL platform

• Designed and built key features for the intranet admin portal, including database schema design, SQL query optimization, and data migration workflows

• Built Playwright automation scripts to scrape, download, and organize 2,000–3,000 legacy PDFs and images across multiple report categories, sustaining ~40+ files/minute throughput

• Containerized the full application with Docker and Docker Compose on Linux, standing up isolated production and hot-reload development environments

• Resolved critical environment and dependency issues (Node version mismatches, volume isolation, network timeouts) to ensure reliable builds across machines

• Built and deployed a live patient-referral platform connecting 13 hospitals and coordinating referrals for 100+ patients, using React.js, Node.js, TypeScript, PostgreSQL, and WebSockets, with REST APIs, JWT authentication, and Cloudinary-based document uploads

• Designed and shipped the hospital's public-facing website (React.js, Tailwind CSS, Vercel) with SEO optimization; live and in active use

• Drove a 40% increase in unique visitors and 32% growth in organic Google search traffic over a 30-day period following the SEO optimization

• Building an internal Hospital Management System (React.js, Node.js, PostgreSQL, Docker) to manage patients, staff, and billing with role-based access control, live tracking, and PDF report generation (in progress)
