# Ajay Singh on Tal

## Headline

Tech Lead @ ZoltMoney \| Cross\-border payments infrastructure — Go, Kubernetes, AWS, React Native \| 9\+ yrs shipping to millions \| ex\-Paytm

## About

Tech Lead with 9\+ years building products millions of people actually use\. Currently architecting ZoltMoney end to end — Go microservices on Kubernetes, React Native app, AWS infrastructure, and the payments and compliance machinery underneath\. What I work on now: moving money across borders\. That looks like one API call and is really a distributed transaction across systems that share neither a clock, a ledger, nor an opinion about failure\. Idempotent transfers, custodial blockchain wallets, multi\-provider KYC orchestration, reconciliation, and the fraud surface around all of it\. The path: GlobalLogic → Good Earth → Trakinvest → Paytm \(Hotels, ONDC, Mall — serving millions\) → Six Sigma Sports \(Web3 on Cosmos\) → ZoltMoney \(founding engineer, 0 → launch\)\. I take complex problems — blockchain wallets, real\-time trading, cross\-border payments — and turn them into clean, fast, reliable products\. Deep in React, Next\.js, TypeScript and React Native on the client; Go, PostgreSQL, RabbitMQ and Kubernetes on the server\. Beyond code: Performer of the Year at Paytm \(2020\-21\), taught 1000\+ students as a TA at UpGrad, audited React courses at Unacademy\. Portfolio: https://thealchemyst\.dev Let's connect if you're building something interesting\.
