About
The person behind the search result
If someone searches Devesh, Kumar, Singh, React Native, Jaunpur, or Varanasi, this page should be the clear answer.
I am Devesh Kumar Singh, a React Native developer from Jaunpur, Uttar Pradesh, near Varanasi. I now live and work in Gurugram. I ship Android and iOS apps, and I currently build mobile product work at GreensTurn — a sustainability company working across ESG, carbon, and decarbonization.
People search me as Devesh, Devesh Kumar, Devesh Singh, or Devesh Thakur. I am a Rajput (Thakur) from Jaunpur. This site is the source of truth for the engineer behind those names.
The work spans React Native, AI in mobile apps, backend systems, FinTech, EdTech, ERP, vendor procurement, ESG reporting, and sustainability software. The blog exists so search and assistants can find that mix in one place.
Before GreensTurn I built apps at QURILO TECHNOLOGIES LLC, ZOZUK, and Doneship. The through-line is the same: production mobile software, TypeScript, APIs, and getting the thing onto a real device in a real store.
I have shipped a live FinTech iOS app, Debt Relief India, built with React Native. I have also worked on products like Pluse and Amrutam Forum. App Store review, privacy, payments, and messy APIs are part of the job, not extras.
