HS is Hansraj Saini, an independent product engineer in Jaipur, India. I take apps built with Lovable, Bolt, Cursor and v0 and make them ready for real users, without starting again.
AI tools get a product to a demo fast. The last 20% is where it breaks: database rules that let anyone read other users' data, API keys visible in the browser, Stripe payments that never reach Supabase, pages Google can't index, and an app that works locally but fails in production. I read the code, rank the risks in a plain-language audit, fix what matters and launch it. You keep the code, the repository and every account.
I also build new web and mobile products, and AI automations that take repeat work off a team, with logs, cost tracking and a person approving anything that touches money or customers.
What I've shipped:
- Unlok: a US stock and ETF investing app, built from an empty repo as its only mobile engineer at Kupa. Live on the App Store and Google Play, with releases that ship from a merge.
- Unlok Insights: an AI newsroom with 16 agents in production, publishing market briefs every trading day. I led it.
- Flyku: the MVP of a US running-club finder, now listing over 1,800 clubs on the web and Google Play.
- Yoga with Latu and Cab in Jaipur: sites with their own CMS that turn visitors into WhatsApp chats and bookings.
Stack: Next.js, React, React Native, TypeScript, Supabase, PostgreSQL, Firebase, Stripe, n8n and Temporal.
How I work: a free 30-minute call, then a written quote for your requirements. I sign an NDA before you share anything, and you see a working build every week. I take calls from 7am to midnight India time, which covers the full UK and European working day and US mornings.
You work with me directly, from the first call to launch. There's no account manager in between.

Our Story
I wrote my first production code in 2023, then built a US investing app from an empty repo and led an AI newsroom with 16 agents in production. In 2026 I made HS my full-time work. Most founders who reach me built something real with AI tools and hit a wall before launch. I fix what's unsafe or broken, keep what works, and hand back code they own. You talk to the person writing the code, every time.
Meet the Team
Hansraj SainiFounder, designer and engineer
Product engineer from Jaipur. Shipped a US investing app on iOS and Android and led an AI newsroom with 16 agents in production. Now I take AI-built apps to production, build new products and automate repeat work.
What Sets Us Apart
You talk to the engineer
There's no account manager or sales team. The person on your call is the person reading and writing your code, from the first call to launch, so nothing gets lost in a handover.Fix what's broken, keep what works
Most AI-built apps don't need a rewrite. A plain-language audit ranks every risk, from open database rules to exposed keys and unverified payments, so you fix what matters first and launch sooner.You own everything
The work lives in your repository and your accounts, and the code is yours once an invoice is paid. I sign an NDA before you share anything, and use least-privilege access while I work.
