From slow to 95+ Lighthouse - with a written plan and real results
Core Web Vitals fixed, bundle sizes cut, LCP under 2.5 seconds. I audit, prioritize, and implement - or give you the plan to do it yourself.
A slow site doesn't just frustrate users - it costs you ranking positions and conversion rate. Studies consistently show a 100ms increase in page load time drops conversions by 1%. I've taken sites from 38 → 97 Lighthouse and know the exact sequence: measure on real users, find the 20% of fixes that unlock 80% of the score, and implement without regressions.

No upsells. No surprise change orders. One scope, one price.
Performance audit report
Full analysis with Lighthouse, WebPageTest, and Chrome UX Report (real-user CrUX data). Every issue severity-ranked by impact on LCP, CLS, INP, and TTFB - with implementation instructions.
LCP under 2.5 seconds
Largest Contentful Paint fixed via image optimization (next/image, AVIF/WebP, preload hints), critical CSS inlining, server response time improvements, and removing render-blocking resources.
Bundle size reduction
Webpack Bundle Analyzer or Rollup Visualizer teardown. Tree-shaking dead imports, code-splitting by route, replacing heavy libraries, and lazy-loading below-fold components.
CLS elimination
Every layout shift tracked to its source: unsized images, late-loading fonts, injected banners, dynamic content without reserved space. Fixed to 0.1 or below.
Server response time (TTFB)
Database query profiling, N+1 query fixes, Redis caching for hot paths, edge CDN configuration, and API route response-time instrumentation.
Before/after evidence
Lighthouse comparison, WebPageTest filmstrip, and a CrUX dashboard showing real-user improvement over 28 days. Stakeholder-ready results you can share.

How we'll work together
Predictable, written-down, no surprises.
- 01
Baseline measurement
Lighthouse + WebPageTest + CrUX field data. I measure on real mobile hardware, not just desktop. No fixing what we haven't measured.
- 02
Prioritised fix plan
Each issue gets an effort vs impact score. The top 5 fixes typically unlock 80% of the score gain. We agree on what's in scope before work starts.
- 03
Implementation
Fixes shipped in small PRs with before/after Lighthouse diffs. No regressions - Lighthouse CI gates every PR.
- 04
Evidence report
Final Lighthouse comparison, WebPageTest filmstrip, and 28-day CrUX trend. A document you can use to show stakeholders what changed and why.
AWS Certified
Solutions Architect
I'm Smit Parekh - a full-stack developer who writes every single line of your code
With 4+ years of experience shipping production systems for FinTech, SaaS, and AI startups, I work as a senior individual contributor - no juniors on your project, no account managers between you and the work. Every commit, every architecture decision, every deployment lands on my machine first.
I specialise in the TypeScript ecosystem - React & Next.js on the frontend, Node.js / NestJS on the backend, PostgreSQL for data, and AWS for infrastructure. I've built headless e-commerce stores, multi-tenant SaaS platforms, real-time dashboards, AI-powered tools, and performance-first marketing sites. The common thread: clean code, zero tech-debt handover docs, and measurable business results.

Me vs. an agency vs. hiring in-house
Three ways to get this built. Here's the honest comparison.
Best value Solo Dev (me) $80-$120 /hr or fixed | Agency $150-$300 /hr blended | In-house hire $80-$120K /yr + benefits | |
|---|---|---|---|
| Start date | 1-2 weeks from quote | 4-8 weeks onboarding | 8-16 weeks to hire |
| Who writes the code | Senior dev - every single line | Junior assigned to your account | Whoever you manage to hire |
| Communication | Direct - you talk to who codes | Via account manager first | Direct, but management overhead |
| Flexibility | Scale up or down any time | Locked to contract length | Fixed headcount, hard to change |
| Code ownership | 100% yours, full handover docs | Depends on contract terms | Yours, but bus factor risk |
| Risk | Weekly demos, fixed scope | Scope creep & handoff gaps | Wrong hire = months lost |
Questions I get asked first
Our Lighthouse score is good in the tool, but real users report it's slow. Why?+
Lighthouse desktop emulates a fast CPU and fast network. Real users on mobile 4G see different results. I always measure with CrUX (28-day real-user data) and WebPageTest on a throttled mobile connection. The lab score and field score often diverge significantly - field data is what actually affects your Search ranking.
Will improving performance affect our SEO?+
Yes, directly. Core Web Vitals are a confirmed Google ranking signal. Improving LCP, CLS, and INP to 'Good' thresholds on the CrUX field data removes a ranking suppressor. The effect is usually visible in Search Console within 4-6 weeks.
Can you optimize a WordPress / PHP site, or only React/Next.js?+
Primarily React, Next.js, and Node.js stacks. For WordPress I can advise on caching strategy, image delivery, and CDN configuration, but I won't implement PHP-level changes.
How long do the improvements last?+
Performance regresses when new code ships without measurement gates. As part of the engagement I add Lighthouse CI to your pipeline so every PR shows a Lighthouse delta - regressions get caught before they reach production.
