Conversion Rate Optimization

Turn the traffic you already have into revenue

Funnel analysis, A/B testing, and friction removal - run by a developer who diagnoses the leak and ships the winning variant, instead of handing your team a slide deck.

Why work with me

You're already paying for the traffic. CRO is the cheapest growth you'll ever buy because it multiplies everything else. I find where users drop, form a real hypothesis, test it properly, and ship the winner - design, copy, and code in one pair of hands.

What you get

Everything included in every engagement

No upsells. No surprise change orders. One scope, one price.

Funnel & analytics teardown

GA4, heatmaps, session recordings, and event data combined into a clear map of where users hesitate, rage-click, and abandon - with the biggest revenue leaks ranked first.

Hypothesis-driven test backlog

Not random button colors. Each test is a written hypothesis tied to a real friction point, sized by expected impact and effort, so you run the experiments that actually move money.

Landing & checkout optimization

Above-the-fold clarity, trust signals, form-field reduction, and mobile-first flows. For e-commerce: checkout, shipping, and abandoned-cart fixes that recover revenue.

Proper A/B testing

Correctly powered tests with a pre-registered hypothesis and a minimum sample size, so you ship real wins - not noise dressed up as a 12% lift on 40 visitors.

Copy & messaging tests

Headlines, value props, and CTA language tested against real users. Often the highest-ROI change on the page is words, not pixels.

Winners shipped to production

Because I'm a developer, the winning variant gets implemented cleanly and permanently - no engineering backlog, no half-built test code left rotting in production.

Predictable, written-down, no surprises.

  1. 01

    Measure & diagnose

    Instrument the funnel properly, then find the real drop-off points with quantitative and qualitative data.

  2. 02

    Prioritise hypotheses

    Build a test backlog scored by impact, confidence, and effort. Run the highest-leverage experiments first.

  3. 03

    Test & ship

    Run powered A/B tests, call the winner with statistical honesty, and ship it to production cleanly.

  4. 04

    Compound

    Each win feeds the next hypothesis. CRO is a flywheel, not a one-off redesign.

Who you'll work with

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.

FAQ

Questions I get asked first

How much traffic do I need for CRO?+

For statistically valid A/B testing, roughly 1,000+ conversions a month per variant is ideal. Below that, I focus on qualitative research, heuristic teardowns, and bigger swings rather than tiny incremental tests - the gains are usually larger anyway.

Do you do the design and development, or just advise?+

Both. That's the point - I diagnose, design the variant, write the copy, and ship the code. You don't need to route my recommendations through a separate engineering team that's three sprints behind.

What tools do you use for testing?+

PostHog or GrowthBook for most product/SaaS work (open-source, dev-friendly, no flicker), VWO or Optimizely when a client already has them. I avoid client-side testing tools that hurt Core Web Vitals where I can.

Can CRO and SEO conflict?+

Occasionally - an aggressive CRO change can strip content SEO needs. I run them together so a conversion win doesn't quietly cost you rankings. See /services/seo for the organic side.
