Hi, I'm Sheriff Sodiq

Full-Stack EngineerWeb, Mobile & Web3

I build and scale production apps — from full-stack SaaS platforms and React Native mobile apps to decentralized Web3 systems and immersive 3D interfaces.

Bridging Logic & Creativity

Sodiq Sheriff, Full-Stack Engineer

Full-Stack Architecture meets Mobile, Web3 & Real-Time Innovation

I build and scale production web and mobile apps for startups and product teams, from API architecture to pixel-perfect frontends. At Figpe, I led a high-performance SPA that cut load times by 30%, and I'm currently the frontend engineer on a SaaS inbox platform and the mobile engineer on a cross-platform app built with React Native and Expo.

Beyond client work, I architect decentralized systems on Ethereum with Solidity and IPFS, build real-time platforms with WebSockets and CRDTs, and craft 3D experiences with Three.js and WebGL: the kind of end-to-end range most frontend developers don't cover.
