Product engineering & founding · Deepak Lather

Two ventures.
Built end to end.

I founded FairPay and Fairstudio, owned FairPay’s account-to-payout funds flow, and built Fairstudio’s protocol and PWA. At Firstwork, ShopUp, and Walmart, I built agents, workflow tools, commerce apps, and API layers.

The work.
And what went into it.

Founder-led ventures first, followed by product tools and the commerce systems I built in earlier roles.

Product & founding / focus

Ownership across the system.

From account opening to payouts at FairPay; from contracts to a leaderboard at Fairstudio. The earlier cases cover workflow builders, self-service commerce, and Asda’s GraphQL layer.

The mechanics, up close

Showing 6 projects.
