About My Web Development Services

Your website is the digital front door to your business — and first impressions are measured in milliseconds. Studies show that 53% of mobile users abandon sites that take longer than 3 seconds to load, and every 100ms of latency costs e-commerce businesses 1% in revenue. As a frontend specialist with deep expertise in React.js, Next.js, and the modern JavaScript ecosystem, I build web applications that load in under 1 second, score 90+ on all four Lighthouse metrics (Performance, Accessibility, Best Practices, SEO), and convert visitors into customers.

I specialize in server-side rendered (SSR) and statically generated (SSG) Next.js applications that give you the best of both worlds — the interactivity of a single-page application with the SEO advantages and initial load speed of traditional server-rendered pages. Whether you need a high-converting marketing site, a data-intensive admin dashboard, a multi-vendor e-commerce platform, or a progressive web app that works offline — I bring the technical expertise to deliver production-quality results using React Server Components, TypeScript, Tailwind CSS, and modern deployment platforms like Vercel.

Beyond raw development, I approach every project with a holistic SEO and web performance mindset. That means semantic HTML structure with proper heading hierarchies, JSON-LD structured data for rich search snippets, Core Web Vitals optimization (LCP, FID, CLS), image optimization with next/image and modern formats (WebP, AVIF), code splitting and lazy loading for minimal bundle sizes, and comprehensive accessibility compliance (WCAG 2.1 Level AA). The result is web applications that rank higher on Google, load faster for users, and perform better commercially.

What I Offer

Comprehensive web development services tailored to your specific business needs, timeline, and budget.

01

Next.js Server-Rendered Applications

Full-featured web applications leveraging Next.js App Router with React Server Components, streaming SSR, and automatic static optimization. Get the interactivity of a SPA with the SEO and performance benefits of server rendering — the best approach for content-rich sites, e-commerce, and applications where search engine visibility matters.

  • React Server Components for optimal performance
  • Streaming SSR and Suspense for fast TTFB
  • Automatic static optimization for pages without data
  • Built-in API routes for serverless backend logic
02

React Single Page Applications (SPA)

Fast, highly interactive SPAs built with React and TypeScript using Vite for development and build tooling. Ideal for internal dashboards, admin panels, and web applications where SEO isn't the primary concern but user experience, real-time data, and complex client-side logic are essential.

  • Contentful, Sanity, Strapi, or WordPress integration
  • Incremental Static Regeneration (ISR) for real-time content
  • Webhook-triggered rebuilds for instant content publishing
  • Edge-cached delivery via Vercel or Cloudflare
08

Web Performance Optimization & Auditing

Performance audit and optimization for existing web applications. I analyze your Core Web Vitals, identify bottlenecks (render-blocking resources, unoptimized images, JavaScript bundle size, layout shifts), and implement fixes that improve load times, Lighthouse scores, and Google search rankings.

  • Core Web Vitals analysis and optimization
  • JavaScript bundle analysis and code splitting
  • Image optimization with modern formats (WebP, AVIF)
  • Font loading strategy and render-blocking resource elimination

Why Work With Me

What sets my approach apart — backed by real production experience, not just theory.

Performance Obsessed

I don't just build websites — I optimize them obsessively. Every project targets perfect 100 Lighthouse scores, sub-second load times, and passing Core Web Vitals. Performance directly impacts SEO rankings, conversion rates, and user satisfaction.

SEO-First Architecture

From semantic HTML and proper heading hierarchies to JSON-LD structured data, canonical URLs, Open Graph tags, and server-side rendering — every technical SEO best practice is baked into the architecture from the start, not bolted on as an afterthought.

Latest React & Next.js Expertise

Proficient in the cutting edge of the React ecosystem — React Server Components, Next.js App Router, streaming SSR, server actions, parallel routes, and intercepting routes. Your project benefits from the latest performance and DX improvements.

Accessible & Inclusive

Every component I build meets WCAG 2.1 Level AA standards — semantic HTML, ARIA attributes, keyboard navigation, focus management, and screen reader testing. Accessibility isn't a checkbox — it's a fundamental quality of well-built software.

Mobile-First Responsive Design

Pixel-perfect responsive implementations that adapt fluidly from 320px mobile screens to 4K displays, using modern CSS techniques like container queries, clamp() typography, and CSS Grid for robust, maintainable layouts.

Full-Stack Capable

As a full-stack developer, I handle API routes, database queries, authentication, and server-side logic within Next.js — no separate backend team needed for most web applications, reducing complexity and cost.

Frequently Asked Questions

Common questions about my web development services — pricing, timeline, process, and more.

How much does it cost to build a web application?

A marketing website or landing page typically costs $2,000–$6,000. A mid-complexity web app (dashboard, SaaS frontend) ranges $8,000–$20,000. Complex e-commerce platforms or full-featured SaaS products start from $20,000+. I provide fixed-price quotes after a discovery session where we define scope together.

What is the difference between SSR, SSG, and SPA?

SSR (Server-Side Rendering) generates HTML on each request — best for dynamic, SEO-critical pages. SSG (Static Site Generation) pre-builds pages at deploy time — fastest loading, ideal for blogs and documentation. SPA (Single Page Application) renders entirely in the browser — best for interactive dashboards and internal tools. Next.js lets you mix all three approaches in one project.

How do you optimize for Core Web Vitals and SEO?

I optimize Largest Contentful Paint (LCP) through image optimization, SSR, and CDN caching. First Input Delay (FID) is minimized by reducing JavaScript bundle size and using code splitting. Cumulative Layout Shift (CLS) is prevented with proper image dimensions, font loading strategies, and skeleton screens. Plus semantic HTML, structured data, and meta optimization for technical SEO.

Can you work with my existing design or design team?

Absolutely. I work from Figma, Sketch, or Adobe XD designs and implement them pixel-perfectly. I also collaborate directly with design teams, providing technical feedback on feasibility, animation performance, and responsive behavior during the design phase.

Do you build e-commerce websites?

Yes, I build custom e-commerce platforms with Next.js. This includes product catalogs, search with filters, cart management, Stripe/Razorpay checkout, order management, and Google Shopping structured data. For simpler needs, I also integrate with Shopify Storefront API as a headless frontend.

How do you handle content management?

For content-driven sites, I integrate headless CMS platforms like Contentful, Sanity, or Strapi. This gives your marketing team a user-friendly editing interface while the frontend remains fast, secure, and fully customizable. Content updates publish instantly via webhooks and ISR.

What is your approach to web accessibility?

I follow WCAG 2.1 Level AA guidelines — semantic HTML, ARIA labels, keyboard navigation, focus management, color contrast ratios, and screen reader testing with NVDA and VoiceOver. I use axe-core for automated audits and supplement with manual testing to ensure truly inclusive experiences.

Do you provide hosting and deployment?

I deploy to Vercel (recommended for Next.js), Netlify, or AWS depending on your requirements. Deployment includes SSL, CDN configuration, environment variables, preview deployments for PRs, and CI/CD pipeline setup with GitHub Actions for automated testing and deployment.

Can you migrate my existing website to a modern stack?

Yes, I regularly migrate websites from WordPress, jQuery-based sites, and older React/Angular codebases to modern Next.js with TypeScript. I handle URL redirect mapping, SEO preservation, content migration, and phased rollout to avoid traffic disruption.

What about ongoing maintenance and updates?

I offer maintenance packages covering dependency updates, security patches, performance monitoring, Lighthouse score tracking, content updates, and feature iterations. Monthly reports include Core Web Vitals trends, traffic analytics, and recommendations for improvement.
