Most ecommerce brands don't know why their conversion rates are what they are. They have GA4 running, but the data isn't clean. Their dashboards don't tell a story. They run A/B tests without understanding the full customer journey. They're making decisions on incomplete information. I work with ecommerce brands and DTC teams to understand what's really happening and then fix it. I design GA4 implementations that actually work, build dashboards you can trust, run CRO experiments that inform strategy, and help you optimize across the entire funnel. After 14+ years helping Shopify and other ecommerce businesses scale, I know where the drops happen and how to fix them. What I own for my clients: Analytics & Measurement Foundations I design and maintain GA4 and GTM implementations that your team actually trusts. This includes custom event tracking, clean data architecture, custom dimensions, and ongoing audits to keep your analytics from degrading over time. Ecommerce & DTC Analytics (my specialty) I specialize in understanding user behavior across the full ecommerce journey from awareness to repeat purchase. I focus on where people drop off, why they convert, product performance, and multi-channel attribution. The goal is to see the real picture of your business. Experimentation & CRO I help teams run focused, disciplined A/B tests that actually inform decisions. Using tools like Google Optimize and Convert, we test systematically and learn what moves the needle. The goal is better decisions, not just higher conversion rates. Reporting & Strategy I build dashboards and reports that leadership can rely on clean, actionable, and built for decision-making. Not vanity metrics. Real insights that inform how you spend money and where you invest next. How I work: Long-term analytics & optimization ownership — I'm not a setup person who disappears. We work together continuously on what matters. GA4 audits and rebuilds — If your tracking is broken or incomplete, I find it, fix it, and rebuild it right. Conversion analysis and experimentation strategy — I help identify what's actually costing you conversions and test the fixes. Direct collaboration with your team — I work alongside your internal teams, agencies, and developers as a trusted advisor. I'm often treated as an extension of the internal team rather than an external vendor. If you're looking for someone to take ownership of your analytics and CRO strategy not just implement tools and partner with your team over the long term, we'll likely be a strong fit.

✓Top Rated Plus ✓ DataVinci CRO ✓ 30% higher conversions in 100 days Gurantee ✓ Free audit ✓ $50M Incremental Revenue Note: I only take 2 new CRO clients per month – to keep delivery quality and speed high. Also: You can go to my site and check my rates directly with the quiz. Guarantee: I guarantee a 30% lift in conversion rates within 100 days – or I'll work for free until you reach this. No games. No fine print. If this sounds like you, keep reading: ✅ You’re driving paid traffic (Google, Meta, TikTok) but ROAS is stuck or falling ✅ You’ve tried redesigns based on “opinions” – nothing moved the needle ✅ You feel like your site leaks money on every page – product pages, checkout, forms ✅ You’ve hired freelancers who promise data but deliver generic checklists ✅ You’re a small business owner (US, UK, CA, AU) doing $1M–$5M+ annually, and you want to scale profitably without doubling ad spend If that’s you – I’m your unfair advantage. What I do differently (and why competitors can’t copy this) Most CRO “experts” guess. They change button colors, rewrite headlines, run random A/B tests – and call it optimization. I am DataVinci. I use a systematic CRO process backed by: →Your analytics – where users actually drop off (not where you think they drop off) →Competition analysis – what your top 3 converting competitors do that you don’t →Voice of customer – heatmaps, session recordings, surveys, live user feedback →A/B testing – design, dev, and statistical validation, not wishful thinking Then – AND ONLY THEN – we redesign or optimize the leaky pages. No fluff. No long reports you’ll never implement. Just execution-ready changes that lift conversions. The results I’ve already delivered (not promises) 🏆 Top Rated Plus on Upwork (top 1% of talent) 🏆 4.9 rating on Clutch – verified testimonials 🏆 Featured on Upwork for systematic CRO & redesign 🏆 80% of clients become long-term partners – because I don’t disappear after one project Real client quote: “Silky’s team rebuilt our checkout flow. Within 60 days, the conversion rate went from 1.9% to 3.1%. ROAS doubled without increasing ad budget.” — Founder, DTC beauty brand (US, $3M annual) My “Done‑For‑You” CRO & Redesign Process : Phase 1 – Audit & Data (Free) →I audit your site – no charge. You get a 5‑page leak report (where, why, how much revenue you’re losing). →Baseline performance + 90‑day revenue roadmap. Phase 2 – Systematic Redesign (Not opinion‑based) : →UX/UI changes based on data, not trends →Copy & offer structuring that matches customer psychology →Mobile‑first – because 70% of your paid traffic is mobile Phase 3 – Development & Launch →Shopify, WordPress, Webflow, or custom (Liquid, PHP, React, headless) →I build it – you don’t touch code Phase 4 – A/B Testing & Iteration →Every change is tested against the original →Winning variants stay – losers are killed fast →You get weekly transparency dashboards, not guesswork What’s included (that others charge extra for) ✅ Free CRO audit – worth $1,500 ✅ No advance payment – you pay after milestone delivery ✅ Full NDA – your data and IP are safe ✅ Real‑time price quote – no hidden fees Here's the thing : Ad costs are rising. You can’t just “spend more.”! The only way to scale profitably is to convert more of the traffic you already have. But most agencies give you a 50‑page PDF audit you’ll never read. Or they run random tests that waste weeks. I give you execution. →Within 10 days, your first test is live. →Within 30 days, you see positive ROI. →Within 100 days, 30% higher conversion rates – guaranteed. Who I work with : Small business owners & DTC brands (US, UK, CA, AU, Europe) Industries: E‑commerce, SaaS, lead generation, service brands Revenue: $1M – $10M+ annually Current conversion rate under 3% – or you feel it’s underperforming Ready to stop leaking revenue?
