[ 00 / Manifesto ]
I build production systems, not demos. Every line I ship runs in a real monolith, handles real traffic, and survives real failures. I care about TTFB, type safety, and time-to-ship — in that order.

The work behind the numbers.

Mahakarshan · Farmology
React Nativei18nRazorpayREST

Solo-shipped a cross-language farming app to Google Play.

The problem

Rural Indian farmers needed a production app in their language — with voice, payments, and a full e-commerce flow.

The approach
  • 43 screens shipped across 18 releases (v6.1 → v7.6) solo
  • i18n in EN, HI, BN, MR, TE, OD with voice input + speech-to-text
  • Catalog → cart → Razorpay → order history → AI chatbot with voice
  • Integrated 30+ REST APIs across product, auth, orders, content
