FRONT END DEVELOPMENT SERVICES

Front-End Development Services Built for Performance, Not Just Pixels

We build interfaces from a real component architecture, not a pixel-perfect mockup with no state model behind it. Performance budgets and accessibility are launch requirements here, not a backlog item for later.

Talk to an engineer

BONUS Free: Front-End Performance Audit Checklist — 18 checks — bundle size, render-blocking assets, Core Web Vitals — run it against your current site before you brief any vendor.

We reply within one business day. No spam, no obligation.

In short: Northell's front-end development builds interfaces from a real component and state architecture, with performance and accessibility as launch requirements, not follow-up work.
CAPABILITIES

What Front-End Development Covers

Component Architecture

Reusable, tested components built against your design tokens, not one-off markup per page.

Performance Engineering

Bundle-size budgets, code-splitting, and image optimization checked in CI before every deploy.

Accessibility (WCAG 2.1 AA)

Keyboard navigation and screen-reader support built in, verified with automated and manual testing.

Design System Implementation

Turns Figma tokens into a real, versioned component library your team can keep extending.

FIT CHECK

Built for Specific Buyers, Not Everyone

Product Teams With a Design, No Build

Have Figma files ready but no front-end capacity to turn them into production code.

Engineering Leads Fixing Performance Debt

Know the site is slow and want it fixed against real budgets, not vague 'make it faster.'

Teams Standardizing on a Design System

Need Figma tokens turned into a maintained component library, not a one-off page.

If you need a page built with no design ready and no design partner, say so upfront — we'll either scope design in or point you to our design services.

PROCESS

From Kickoff to Launch

01

Design & Token Audit

We review the design files and existing component library, if any, before writing code.

→ Component inventory + technical plan
02

Component Build

Components built and tested in isolation (Storybook or equivalent) before assembly into pages.

→ Tested component library
03

Page Assembly & Integration

Pages assembled from components, wired to your API or CMS, with real data, not lorem ipsum.

→ Working pages against real data
04

Performance & QA Pass

Bundle-size, Core Web Vitals, and accessibility checks before launch, not after.

→ Launch-ready, audited build

FAQ

Common Questions About Front-End Development

Do you work from our existing design system?

Yes — we build components against your existing design tokens and library when one exists. If it doesn't, we'll flag that early since it changes the scope and timeline.

Which frameworks do you build in?

React and Next.js are our default, with Vue where a codebase already standardizes on it. We pick based on your existing stack, not a default preference.

How do you handle performance?

Performance budgets (bundle size, Core Web Vitals targets) are set during scoping and checked in CI, not discovered after launch when a user complains.

Is accessibility included by default?

Yes — WCAG 2.1 AA is the baseline on every build, checked with automated tooling plus a manual keyboard/screen-reader pass before launch.

Can you take over an existing front-end codebase?

Regularly. We start with a codebase audit — component reuse, state management patterns, technical debt — before committing to a timeline for new work.
