The Developer
Behind the Code

I'm Mayank Prajapati, a Full-Stack and Mobile Developer based in New Delhi. I currently work at Rashi Technologies on the Meri Bhakti platform, where I build and maintain production systems that handle 5,000+ concurrent users during peak traffic.

Full-Stack: I work across the entire stack with Next.js, Express.js, MongoDB, and Payload CMS to build e-commerce flows, booking systems, and backend services that power real-time notifications — supporting 100+ bookings per hour.

Mobile: I previously led Flutter development on the same platform, building end-to-end Puja and Chadhava booking experiences. The app scaled to 1.2 lakh+ downloads across iOS and Android. I reduced app startup time by nearly 2 seconds and cut listing API payload by ~60%.

“I care about systems that work at scale — not just code that runs in development.”
