Jonathan Kalu

Hi, I'm Jonathan, a frontend engineer who builds web products end-to-end, from zero to launch, with the product instinct of a founder and the execution speed of someone who ships under pressure. I specialise in React, Next.js, and TypeScript and modern frameworks, delivering fast, visually precise interfaces across startups, agencies, and established companies. From high-traffic mentorship platforms to production-ready commercial websites, my focus is always the same: build something that works, looks sharp, and drives real results. I work closely with product teams and designers to translate vision into high-performing digital experiences, owning the full frontend lifecycle from Figma interpretation through to deployment. Beyond implementation, I identify friction points, optimise onboarding flows, and strengthen engagement loops that directly impact user retention and growth. Having run and managed an IT firm, I understand execution speed, client communication, and accountability at every stage of a product. I don't wait for a ticket; I take ownership and deliver.
