I help CRO teams and DTC brands turn fragile Shopify themes into stable, experiment‑ready storefronts. My work lives in Liquid, metafields and vanilla JavaScript, running theme‑level A/B tests through GrowthBook and Shoplift, with no flicker, no broken variants, and no impact on Core Web Vitals. I am not a general Shopify developer. I specialize in one thing: building and shipping Shopify experiments that protect revenue while testing bold ideas. I can join strategy calls with your CRO team, walk through the hypothesis, propose the cleanest architecture, and then go into the theme and make it real. 🎯 What I do for Shopify brands & CRO agencies — Theme‑level A/B tests using GrowthBook, Shoplift and custom feature flags (no overlay tools, no DOM swaps, no flicker). — High‑conversion PDPs for complex catalogs: metafield‑driven variants, coverage × material selectors, and size & fit UX that reduces friction instead of adding more clicks. — Mobile‑first PDP UX: sticky add‑to‑cart bars, clean buy boxes, and trust elements, reviews and FAQs placed where real users actually interact. — Cart drawer optimization: free‑shipping thresholds, discount clarity, total savings lines and cross‑sell placements that do not slow the store down. — Metafield architectures and Matrixify workflows so experiments scale across hundreds of SKUs without fragile manual hacks. ✅ What you get working with me — Clean, isolated, and documented Liquid code your team can review and roll back easily. — A duplicate‑theme build process that never touches production until QA is done. — Structured QA across devices, browsers, variant states, stock states, discounts and back‑in‑stock flows before anything goes live. — Clear implementation plans up front: which templates and snippets we touch, what metafields schema we use, and how we handle rollout. — A developer who stays available during launch windows to catch race conditions and edge cases before they touch revenue. 📂 Recent projects For a 4x4 accessories brand, I consolidated 200+ separate products into a single metafield‑driven PDP with a coverage × material selector, then wired it into a Shoplift A/B test running across 218 SKUs without touching checkout behavior. For a European lingerie brand, I rebuilt the entire mobile PDP and size‑selection UX: sticky add‑to‑cart bar, a size matrix showing stock and sale states per variant, and a cleaner minicart that makes discounts and final totals easy to read instead of confusing. 🛠️ Tech stack Shopify · Shopify Plus · Liquid · JavaScript · HTML · CSS · GrowthBook · Shoplift · Matrixify · Figma · GA4 · Klaviyo · Core Web Vitals 🏪 Best fit for CRO agencies running theme‑level experiments · DTC brands on Shopify or Shopify Plus · Teams that already have hypotheses and designs and need clean, QA'd Liquid implementation · Stores with complex catalogs (metafields, multi‑variant PDPs, 100+ SKUs). Invite me to your job, share your store URL, and I will come back with a quick audit and a concrete plan for your next test or PDP sprint.

Hey! Robin here. I help business owners integrate AI technologies into their workflows. Check out my 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗰𝗮𝘁𝗮𝗹𝗼𝗴 for budget-friendly, self-hosted AI solutions fine-tuned to your specific needs. ● 𝗔𝗯𝗼𝘂𝘁 𝗠𝗲 Hi, I'm Robin — a Mechatronic Engineer who was drawn to the “dark side” of software development early in my career. Always striving to stay up to date, I've gained real-world experience with most of today’s popular software development technologies (full list below). I take time to understand both the business goals and the technical requirements of your project before writing a single line of code. This ensures you're paying for solutions that truly work, pushing your project in the right direction with every sprint. I'm not the kind of freelancer who just completes tasks for the sake of getting paid. I've been working as a software developer since 2006 and on Upwork (formerly oDesk) since 2012. Freelance projects here put food on my table, so you can expect full dedication. I only take on one job at a time and always aim to respond quickly. I'm online during standard office hours, Monday through Saturday, and my time zone is GMT-5 (same as New York) year-round. ● 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀 Ongoing (Back-end Developer) Vagrant, RESTful 2018–2020 (Java Web Development) Spring Boot, JSF, PrimeFaces, JAXB, JAX-RS, SQL Server 2008 2017–2018 (JavaScript Mobile) Node.js, Express, React Native, iOS, Xcode, Blockchain 2013–2017 (PHP Web Developer) PHP 5, MySQL, Laravel, Lumen, AWS EC2, AWS RDS, AWS CodePipeline, AWS Elastic Beanstalk, Cloud9 IDE, GitHub, Bitbucket 2012–2014 (Java Desktop and Web) J2SE, Struts, Derby DB, MySQL, JDBC, Hibernate, Jasper Reports, NetBeans, Tomcat 2009–2012 (.NET Web Developer) Visual Studio 2008–2010, ASPX, ADO.NET, Silverlight, MVC (.NET), WCF, ADO.NET Data Services, MS SQL Server, Oracle, SVN, Scrum 2007–2009 (Windows Desktop Software) Borland Delphi 6, MS SQL Server 2000, Oracle, Firebird, JEDI Version Control System, PMP/Waterfall methodologies 2006–2007 (Hardware–Software Integration) C/C++, Borland Builder 5 & 6, OLE DB, ADO components
