I build Shopify stores, landing pages, and lead systems engineered to turn traffic into buyers, booked calls, and trackable opportunities. Most ecommerce and service-business sites look fine but leak sales through slow pages, weak offers, checkout friction, missed inquiries, and unclear tracking. I fix that with conversion-focused design, clean development, SEO/AI-search structure, and practical automation. What clients hire me for: - Shopify store setup, custom themes, product pages, and template customization - High-converting landing pages built around the customer journey - CRO: product pages, checkout flow, upsells, trust, analytics, and testing ideas - SEO + AI-search optimization: structured content, intent mapping, schema, and FAQs - Lead capture systems, AI chatbot/receptionist flows, CRM handoffs, and follow-up automations - Facebook Ads setup, GA4 tracking, Looker Studio dashboards, and marketing automation Why me: - $5K+ earned and 780+ hours worked on Upwork - Delivered for brands in the US, Canada, Mexico, and Latin America - Fully bilingual in English and Spanish - Design, development, copy, SEO, and automation in one practical build process - Clear communication and fast response times Free audit: share your site or project brief and I will send back a 3-point breakdown of what is costing you sales or leads and the quickest fixes to start with. Message me or invite me to your job. I take on a limited number of projects at a time so each build gets focused attention.

I lead web strategy and demand generation for SaaS companies, where I own paid media, SEO/AEO, web development, and measurement across four distinct properties. I help businesses turn their websites into measurable revenue engines, not just digital brochures. What I do best: - Conversion rate optimization: I audit funnels, structure experiments, and fix the measurement gaps that hide where revenue leaks. I work from data, validating assumptions before concluding. - SEO and AEO: I resolve keyword cannibalization, build content routing strategies, and optimize for both traditional search and AI answer engines using tools like Screaming Frog, GSC, GA4, Semrush, and Peec AI. - Web development and CRO infrastructure: I bridge strategy and execution, from cookie consent and tag governance to experimentation platforms and clean analytics implementation. - AI-augmented web management: I use AI to accelerate audits, content workflows, and reporting so teams move faster without sacrificing rigor. I bring an operator's perspective: I think in terms of cost-per-SQL, attribution, and pipeline impact, not vanity metrics. Clear communication and reliable delivery are how I work.

Founder of Ecom Surge | 7+ Years in CRO | Shopify Plus Partner I've run over 100 A/B tests for ecommerce brands and helped generate $10m+ in additional annual revenue. My clients typically stay 2+ years because the results compound. Some recent wins: ⭐ 300% conversion rate increase in 2 months ⭐ +$100k additional monthly from two tests (48% RPV lift on Collection Page + 18% lift in RPV on homepage in month one) ⭐ 33% lift in AOV through one test For brands doing $1m+ in annual sales, I guarantee 5x ROI within 3 months or I work for free until we hit it. The problem I solve: You're driving traffic but conversions aren't scaling with it. You've tried tweaking things yourself or worked with agencies that handed you off to account managers who don't actually understand CRO. You're stuck guessing what to test instead of knowing. How I'm different: No account managers. No middlemen. I'm the strategist, and I handle everything directly: data analysis, user behavior research, test ideation, and prioritization. My team of designers and developers executes, but I'm in the weeds with you from day one. This matters because CRO isn't about running random tests from a "best practices" checklist. It's about understanding where your funnel is leaking, why visitors aren't converting, and building a testing roadmap that compounds gains over time. What working together looks like: 1. Funnel analysis - I dig into your analytics to find where revenue is actually being lost. Not surface-level bounce rates, but the specific friction points killing conversions. 2. User behavior research - Heatmaps, session recordings, and qualitative data to understand the "why" behind the numbers. 3. Test prioritization - Not every idea is worth testing. I prioritize based on potential impact and confidence level so we're not wasting time on low-yield experiments. 4. Execution - My team designs and develops every test. You're not stuck trying to implement recommendations yourself or hiring separately. 5. Analysis and iteration - We don't just call winners and move on. I analyze why tests won or lost so each experiment informs the next. What clients say: ⭐⭐⭐⭐⭐ "In the first month of our partnership, not only did Ecom Surge perform an in-depth audit that paved the way for our collaboration, but they also ran two successful A/B tests. The first test resulted in a 48% increase in traffic through the collection page, and the second test led to an 18% increase in the conversion rate through the homepage." ⭐⭐⭐⭐⭐ "First when we hopped on our consultation call Sagi had experience and data behind every action he recommended. I could tell he was a pro with real industry experience. After just 1 week of adjustment recommendations my website conversion rate increased by 200%." ⭐⭐⭐⭐⭐ "They analyze your website and provide data-driven insights to increase conversions like no other. They are the best team you can hire when trying to find ways to improve sales on your website." Who this is for: Ecommerce brands serious about growth. I work across all platforms, not just Shopify, though that's where most of my experience sits. If you're doing meaningful revenue and want to scale conversions without the agency runaround, we should talk. Who this isn't for: Brands looking for a quick fix or someone to just "make the button green." CRO is a process. If you want sustainable, compounding growth, I can help. If you want magic overnight, I'm not your guy. Send me a message and let's see if there's a fit.
