Front End Development

The interface is the product on a phone in traffic. We engineer front ends that stay usable on uneven networks, keep JavaScript honest, and wire the buttons people actually use: WhatsApp, EcoCash, Paynow, Ozow, M-Pesa and card, without shipping a US template that assumes fibre and Apple Pay.

Scope a front-end buildHow we work
Code on a screen during front-end development
LCP
Google's Core Web Vitals documentation treats Largest Contentful Paint as a ranking and UX input. Industry target bands are public; we measure on mobile, not only on office wifi.
3G
Industry network reality in parts of the region: a page that is fine on fibre fails on a congested cell. We budget weight as a product constraint.
JS
Industry performance practice: unused JavaScript is the usual reason a marketing site feels broken. We ship less, then enhance.
A11y
WCAG is the industry baseline for inclusive interfaces. Keyboard, contrast and forms are part of the build, not a later audit surprise.

Industry benchmarks, not Accerstus client results. Verify before citing.

We ship interfaces that load, convert and keep working off wifi.

FRAMEWORK APPROACH

Front-end work here is performance, design implementation and integration. We sit between brand, CMS and payment widgets so the page the designer signed off is the page a customer in Kitwe can actually use.

Implement the design system in code.

Spacing, type, components and states, including error and empty. Pixel-perfect on a 27-inch monitor is not the brief if the tap target fails on a 6-inch Android.

Budget the bytes.

Image formats, font subsets, code splitting, and no third-party tags that stall LCP. Analytics still fire; they do not own the main thread.

Integrate local actions.

WhatsApp deep links, payment redirects, maps that do not download the world, and forms that survive a dropped connection.

OUR PHILOSOPHY

HTML first

If the core journey needs a megabyte of framework to show a price, the stack is wrong for the market. Progressive enhancement is the default.

Measure on real devices

Lab Lighthouse is a start. We care how the page behaves on mid-range Android, which is the device mix, not a footnote.

CMS authors should not break layout

We build components editors can fill without collapsing the grid. A marketing site that only a developer can update is unfinished.

No fake speed

Skeleton screens that never resolve, and spinners over empty APIs, are not performance. We fail visibly and recover.

Frequently Asked Questions

No. We pick the stack the product already uses, or the simplest stack that meets the performance budget. React and Next.js are common; they are not mandatory.
Often yes. Many projects are a new front end on a living CMS or commerce engine. Scope depends on the APIs and templates we inherit.
It can, because Google uses mobile performance as an input, and because people bounce less. It is not a substitute for crawlable content and metadata.
Yes, when those integrations are in the brief. We implement click-to-chat and payment widgets the business already has access to; we do not invent a banking partnership.
