Hospitals run their entire operation on it — admissions to payouts.

Multi-tenant hospital management SaaS covering 20+ clinical and financial modules. Its payroll engine computes doctor revenue-sharing and pushes automated RazorpayX payouts; WhatsApp automation keeps patients informed; role-based access control and audit trails keep every action accountable — the parts a hospital cannot operate without.

India's first real-time online exam platform for CID recruitment.

Built for the Andhra Pradesh Crime Investigation Department to move officer recruitment online. It held 1,500+ concurrent candidates on exam day and replaced manual grading with an automated pipeline — results that took hours now land in minutes at 99.9% accuracy, behind JWT auth and role-based access.

Clinic management SaaS I build, sell, and support myself.

My own product, not client work: clinics get appointment bookings, WhatsApp notifications for patients, and subscription pricing. I handle the whole loop — building the software, selling it to clinics, and keeping paying customers running. It is the closest thing on this page to a founder's job description.

Company website rebuilt and relaunched end to end. Engagement rose 40%.

Took the company's public site from brief to launch alone: rebuilt on Next.js with SEO and performance as first-class requirements, not afterthoughts. Post-launch engagement rose 40% — the site went from a liability to the way clients find them.

Client site for a German wind-energy consultancy — my first international client.

CTCAP, a wind-energy consultancy in Germany, handed me their public site and I delivered it end to end — working remotely across time zones, from brief to launch on their own domain. Proof I can be trusted with a client relationship, not just a ticket queue.
