I'm Isaac Anyimiah, a senior frontend engineer specializing in Next.js, TypeScript, and Node.js, building user-centered, scalable applications. I've delivered interfaces for high-profile clients including Pizza Hut, Premier Inn, Mulberry, and Omaze.

Most recently at One Rent, a car rental marketplace, I worked across both the customer-facing website and the internal admin dashboard on a nine-developer team. I owned the digital vehicle-inspection tool that rental staff use to record damage at handover, built it offline-first so it works in parking lots with weak signal, and was the sole frontend developer on a new monthly car-subscription product, building every screen from company pricing flows to staff review.

Before that I spent nearly three years at Topflight Digital as the sole frontend developer, building and shipping their entire website and running the A/B testing program across landing, listing, and product detail pages. I introduced a React-based testing workflow that brought component-based development into experimentation, so complex test variations became faster to build and easier to maintain, and built the in-house statistical tool that replaced evaluating those results by hand in a spreadsheet.

The thread through all of it: I look for the step someone is doing manually because nobody built the tool yet, and then I build the tool.

How I work

What working with me looks like.

  1. 01

    I own the whole surface

    I've been the sole frontend developer on a shipped website and on a new product line. Give me the problem and I'll build every screen it needs, flag what's risky early, and ship. You don't have to chase me.

  2. 02

    I'm useful in week two

    Three months at One Rent: I owned the inspection tool, shipped a subscription product solo, integrated AI listing generation, and rolled i18n across two surfaces. I read the codebase, find who to ask, and start shipping before the onboarding doc is finished.

  3. 03

    I measure instead of guessing

    Two years of running A/B tests taught me to distrust a good-looking result. If a change is supposed to move conversion or bounce rate, I want the significance calculation, not a screenshot of a dashboard on a good day.

  4. 04

    I build for the bad conditions

    Weak signal, dropped connections, a reload halfway through a task, a user who reads none of the six supported languages the same way. The happy path is the easy half; I plan for the rest of it up front.
