About
Chinemerem Daniel
Owerri, Nigeria@codacdanny

I'm Chinemerem — a senior frontend engineer who likes the messy, exciting start of things.

I'm a Senior Frontend Engineer with 6+ years shipping production web apps in React, Next.js and TypeScript — and a full-stack range that reaches into NestJS, Solana/Anchor and on-chain systems when a product needs it.

I currently lead the core recruiter experience at Parallel. Outside of that I build my own products end to end — a perpetual football-odds market on Solana, a university result-processing SaaS, an on-chain proof-of-income tool — because taking something from an empty repo to a thing people use is the part I love most.

I studied Mathematics at the Federal University of Technology, Owerri. I care about performance, motion, and interfaces that feel considered down to the last 8 pixels.
