01 — about me

I own the product from schema to screen.

I'm Ritik, a full-stack engineer at Durolt, where I build the Smart Locker platform across web and mobile. Outside work I build and self-host complete products: a multi-module education platform, a multi-tenant website builder, a real-time music app.

I design the API, model the data, build the web app and the mobile app, then deploy them myself on servers I tune by hand. Teams get one person who can take a feature from database to device without hand-offs.
