Frontend Development
Fast, accessible frontends in React and Next.js that hold up as you scale
Production React, Next.js and TypeScript interfaces built for real Core Web Vitals scores, real accessibility, and a codebase your team can still move quickly in two years from now.
I build production frontends in React, Next.js and TypeScript: the user-facing layer that decides whether your product feels fast and trustworthy or slow and broken. That means typed components, sane state management, and rendering choices (SSR, SSG, ISR, client) made on purpose rather than by default. Whether it is a marketing site that needs to load instantly or a data-heavy dashboard that needs to stay responsive, I ship interfaces that work on real devices and real networks, not just on a fast laptop.
Most frontend problems I get hired to fix are not exotic. Pages that fail Core Web Vitals and quietly cost you conversions and search ranking. A component library that everyone copies and nobody trusts. Accessibility that was an afterthought and is now a legal and UX liability. State logic so tangled that every new feature breaks two old ones. I focus on the unglamorous parts, performance budgets, a real design system, WCAG compliance baked in from the start, so the interface stays fast and maintainable as the team and the feature set grow.
Seventeen years and 15,000+ hours of Top Rated Plus work on Upwork mean I have watched a lot of frontends rot, and I know which decisions cause it. I optimize for the total cost of the codebase, not just the demo: clear component boundaries, typed contracts, and the kind of structure that lets a new engineer ship in their first week instead of their first month. You get senior judgment on the tradeoffs that matter, hydration cost, bundle size, re-render behavior, a11y, and a frontend that is a foundation to build on rather than a thing you eventually rewrite.
What you get
Deliverables
Production React app
A deployed, typed React or Next.js application with rendering strategy chosen per route for speed and SEO.
Design system
A documented, reusable component library in Storybook so every screen stays consistent and fast to build.
Core Web Vitals report
Measured LCP, INP and CLS scores with the specific fixes that got them into the green, not just promises.
Accessibility pass
WCAG 2.1 AA conformance with keyboard navigation, focus management, and screen-reader support verified, not assumed.
Automated test suite
Component and end-to-end tests with Vitest and Playwright so regressions get caught before users do.
Handoff documentation
Architecture notes, component usage docs, and setup instructions so your team can own the code from day one.
Stack
Technologies I use for this
How it goes
The engagement
Audit & scope
I review your designs, existing code and goals, then map the architecture, rendering strategy, and a clear scope before writing a line.
Design system first
I build the shared component foundation and tokens early so feature work is fast, consistent, and accessible by default.
Build & measure
I ship features in reviewable increments, tracking Core Web Vitals and accessibility as I go rather than at the end.
Harden & hand off
I add tests, fix the last performance and a11y gaps, and document everything so your team can take it forward confidently.
FAQ
Questions about Frontend Development
- Can you work from our existing Figma designs and design system?
- Yes. I implement pixel-accurate React and Next.js components from Figma, and if you already have a design system I extend it cleanly rather than reinventing it. If you do not have one, I can build a reusable component library as part of the engagement.
- Do you only do greenfield projects, or can you improve an existing frontend?
- Both. A large share of my work is improving existing React and Next.js codebases, fixing Core Web Vitals, untangling state, adding accessibility, and refactoring components, without a risky full rewrite. I start with an audit so you know exactly what is worth changing and why.
- How do you handle performance and Core Web Vitals?
- I treat performance as a budget, not an afterthought: correct rendering strategy per route, controlled bundle size, image and font optimization, and minimized re-renders. I measure LCP, INP and CLS with Lighthouse and field data, and I report the before-and-after numbers.
- Is accessibility included or an add-on?
- It is baked in. I build to WCAG 2.1 AA with semantic markup, keyboard support, focus management and proper ARIA from the start, because retrofitting accessibility later is far more expensive and error-prone than doing it correctly the first time.
