Products in production, used by real people

From a global trading platform and a 500-store coffee chain to India's JEE/NEET coaching, a CBSE school and a Jaipur wholesaler. The code is private, so here's what each product does and the part I built.

Featured · Client project Neem Karoli Sales, Jaipur

A complete wholesale ordering platform: two Android apps and the API behind them

A beverage wholesaler took every order over the phone and on paper. I designed and built the whole system on my own: a shop app where retailers order by the case, a staff app for depot and delivery teams, a web admin, and the API behind them.

Android apps that update themselves outside the Play Store, with forced updates and the ability to pull back a bad release
Phone and OTP sign-in run by our own server, with SMS and a WhatsApp fallback
Cashfree payments that are always checked against the gateway, and GST invoices as PDFs
Prices calculated on the server in whole paise, an order state machine, and 1,290+ automated tests

Pickup Coffee: data platform and the apps behind 500+ stores

One of the Philippines' fastest-growing coffee chains, now expanding into Mexico. I first built their data platform: Airflow pipelines moving data from Google Cloud Storage into BigQuery, and Metabase dashboards for the marketing team. Then I moved to the backend of their three apps: the customer ordering app, the barista tablet app in every store, and the back office for menus and pricing.

Questions people often ask

Quick answers about my work, how a project runs, and how to reach me.

Who is Gajraj Singh Shekhawat?

Gajraj Singh Shekhawat (also known as Gajraj Shekhawat) is a software engineer (backend and full-stack) based in India who works remotely with teams worldwide, with 4+ years of experience building production software.

Which companies has Gajraj worked with?

At Shuru Technologies he works on Equiti's multi-asset trading platform, and before that built the data platform and app backends for Pickup Coffee, a coffee chain in the Philippines and Mexico.

As an independent consultant he has built products for Yugam International School, Neem Karoli Sales, Shikhar Classes and Gram Sansad.

Can I hire Gajraj as a remote software engineer or consultant?

What kind of projects does Gajraj work on?

Web and mobile apps, backend systems and APIs, data pipelines and dashboards, payment and WhatsApp integrations, AI features, and software for schools and coaching institutes.

Can Gajraj be our technical advisor?

Yes. He advises founders and organisations on architecture, choosing the right stack, build-versus-buy decisions, reviewing agency or vendor work, hiring developers and planning the product roadmap. He plays this role for Yugam International School, where he leads the technology team.

Can he build a complete product from scratch?

Yes. He regularly takes products from idea to launch on his own: planning, design, backend, web and Android apps, payments, deployment and support after launch. The Neem Karoli Sales ordering platform, for example, was designed and built end to end by him.

Yes. He has built a text-to-SQL agent on a self-hosted model, AI reading of exam answer sheets, Indian-language call transcription and summaries, and an AI lesson planner. He can also host models privately when data privacy or running cost matters.

How does a project start, and how is it priced?

It starts with a short call to understand the problem. You then get a clear scope, timeline and fixed quote before any work begins, followed by weekly demos during the build.
