About

Engineer. Builder.
In blockchain since 2014.

Background

Senior Backend & Blockchain Engineer with 7+ years shipping production systems. I build the full stack — TypeScript/GoLang backend services, REST APIs, cloud infrastructure on AWS, and Solidity/Rust smart contracts.

At Winston Artory Group in Berlin I own the complete smart contract lifecycle: architecture, Solidity development, test suites, mainnet deployment, and on-chain event monitoring. The backend services I built bridge on-chain events to off-chain application state in real time.

At Dappomatics I've delivered end-to-end Web3 engineering for 5+ client products across DeFi, NFT, and RWA tokenization on Ethereum and Polygon. I've been in Bitcoin and blockchain since 2014 — building one of Pakistan's first crypto communities before it was mainstream.
