What I Do

What Does Frontend Development Actually Cover?

Frontend development covers everything a user sees and interacts with — from visual design implementation and responsive layout to interactive components, animations and the JavaScript logic that ties it all together. It's the difference between a site that works and a site that converts.

My frontend work spans hand-coded HTML/CSS themes, React and Vue single-page applications, Figma-to-pixel-perfect conversions and performance optimisation for existing interfaces. I bring both technical precision and genuine design sensibility — the UI I build doesn't just function, it looks and feels considered.

Every interface I deliver is accessible, responsive across all viewports and optimised for Core Web Vitals — because a beautiful site that loads slowly or breaks on mobile isn't actually serving your users.

What You Get

What a Freelance Frontend Developer Can Do for Your Project

Good frontend work is the difference between a product that impresses users and one that frustrates them. Here's what that looks like in practice.

✓

Figma / PSD to Pixel-Perfect Code

I convert design files into clean HTML, CSS and JavaScript that matches the original design precisely — consistent spacing, correct typography, accurate colours and smooth micro-interactions throughout.

✓

React & Vue SPA Development

Single-page applications with component architecture, Redux or Pinia state management, React Router / Vue Router, lazy loading and clean integration with your backend API or headless CMS.

✓

Responsive & Mobile-First Design

Every interface I build works flawlessly from 320px mobile to 4K desktop. I approach layout with a mobile-first mindset so the responsive behaviour is structural, not a series of overrides bolted on at the end.

✓

Performance & Core Web Vitals

LCP, CLS and INP optimised from the ground up — lazy loading, image compression, font preloading, code splitting and CDN configuration. Measurable PageSpeed improvements, not just theoretical gains.

✓

eCommerce Frontend

Product listing pages, cart interfaces, checkout flows and account dashboards for WooCommerce, Shopify and Magento — designed to reduce friction and increase conversion rates.

✓

Existing UI Improvements

Refactor an ageing interface, fix responsive breakpoints, modernise a dated visual design or improve accessibility — I can audit and improve what you already have without a complete rebuild.

The Craft

Why Great Frontend Matters for Your Business

The frontend is what your users actually experience. Its quality directly affects bounce rates, conversions and brand perception.

📈

Conversion Rate Impact

A one-second delay in page load time reduces conversions by up to 7%. Clean, fast frontend development directly affects your bottom line — it's not a cosmetic concern.

🔍

SEO Foundation

Core Web Vitals are a Google ranking factor. A well-built frontend with clean semantic HTML, proper heading hierarchy and fast LCP directly supports your organic search visibility.

👥

User Retention

Intuitive navigation, fast interactions and consistent visual language keep users engaged longer. A frustrating interface sends users to your competitors — a smooth one brings them back.

📱

Mobile-First Audience

Over 60% of web traffic comes from mobile devices. A frontend built with genuine mobile-first thinking — not just responsive overrides — performs correctly for the majority of your users.

♿

Accessibility & Inclusion

WCAG-compliant interfaces reach a wider audience and reduce legal risk. Semantic HTML, ARIA attributes, keyboard navigation and sufficient colour contrast are built-in from the start.

💻

Maintainable Codebase

Component-based architecture and CSS custom properties make future updates fast and predictable. A well-structured frontend means your team can make changes without breaking unrelated parts of the UI.

Why Harwinder

Why Hire Me as Your Freelance Frontend Developer?

Technical precision combined with genuine design sensibility — that combination is rarer than it should be in frontend development.

📅

12+ Years of Frontend Experience

I've been building web interfaces since the jQuery era. I've worked through every major shift in frontend development — and the fundamentals I built on (HTML, CSS, accessibility, performance) remain the bedrock of every project.

🎨

Strong Design Sensibility

I work closely with Figma files and design systems to produce interfaces that match the original intent precisely — not approximations. Spacing, typography, colour and motion all get the same level of attention as the functional code.

💻

Technical Proficiency

HTML5, CSS3, JavaScript ES6+, React, Vue, TypeScript, Tailwind, SCSS — I use the right tool for the project. My PHP/Laravel background also means I can communicate cleanly with backend teams and implement API-driven frontends correctly.

🚀

Performance-Obsessed

Every site I deliver targets 90+ PageSpeed on mobile. I've self-hosted fonts, eliminated render-blocking resources, implemented composited animations and optimised critical rendering paths — measurable results, not just good intentions.

📋

Responsive by Design

I design and build mobile-first. Every breakpoint is considered, every touch target is sized correctly and every interaction works as well on a phone as it does on a 27-inch monitor.

🔁

Collaborative & Transparent

I provide regular staging updates, welcome feedback at every stage and document what I've built so your team can maintain it. No black-box code, no going dark mid-project.

💰

Competitive, Transparent Rates

Frontend development starts at $30/hr. Fixed-price project quotes available for clearly scoped work — you know the cost before anything begins.

💬

Timely Delivery

Completing on schedule and on budget is a firm priority. I manage technical complexity independently — so your timelines don't slip because of frontend bottlenecks on my end.

How It Works

My Process for Your Frontend Project

A structured, transparent process — so you always know exactly where the project stands and what comes next.

Discovery

A free 30-minute call to understand your goals, brand guidelines, target audience, technical constraints and what success looks like. The better I understand the context, the better the outcome.

Design Review

Review of existing Figma/PSD files or brand materials. I flag anything that's ambiguous or technically problematic before development begins — saves rounds of revision later.

Proposal & Scope

A detailed written proposal covering component breakdown, tech stack, milestones, cost and timeline. All dependencies and integration points clearly documented before a single line of code.

Development

Component-by-component development with regular staging deployments. I work mobile-first, building and verifying each breakpoint as I go — not patching responsive behaviour at the end.

Cross-Browser QA

Testing across Chrome, Safari, Firefox and Edge on desktop and mobile. Every layout, interaction and animation verified to work consistently — no "works on my machine" surprises.

Performance Audit

PageSpeed analysis, Core Web Vitals check, accessibility audit and SEO validation. Any issues found are fixed before the project is considered done — not listed in a separate ticket.

Revisions

Two rounds of revisions included in every project. Feedback is incorporated quickly, with staging updates usually same-day. You see every change before it goes live.

Delivery

Production deployment, full codebase handover and written documentation. The first 30 days of questions and minor tweaks are covered at no extra charge.

Ongoing Support

Retainer-based maintenance for updates, new features and performance monitoring — so your frontend stays current as your product evolves and your user base grows.
