Marcus Bennett
Principal Software Engineer, Coding Dunia
Marcus has spent 20 years shipping production code at startups and Fortune 500 companies, most recently as tech lead at two YC-backed SaaS platforms. He's built React apps serving 4M+ daily users, mass-migrated legacy jQuery codebases to TypeScript, and spent enough time chasing Core Web Vitals regressions across 30+ projects to have opinions about it.
He's an AWS Certified Solutions Architect and a Google Developer Expert in Web Technologies. Right now he's mostly interested in edge rendering and signal-based reactivity — the parts of the frontend stack that keep changing every time you get comfortable with the last approach.
What Marcus Writes About
- React, TypeScript, and JavaScript patterns tested against real production code
