Hire the Best Shopify Developers
in Colombia

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).

I build the parts of Shopify most developers won't touch — checkout UI extensions, B2B purchasing flows, and metafield architecture that holds up as the catalog grows — and I came to it from 7 years as a UX/UI designer, so what I ship doesn't look like a developer designed it. That combination means one person handles the whole path from Figma to production. No handoff gap, no "technically it works" compromises, no second contractor to brief. Recent work: inventory-validation extensions at checkout, B2B blocks scoped to company context, custom Online Store 2.0 sections built from Figma files, carrier-calculated shipping diagnostics on live Grow-plan stores, metafield structures for catalogs past 100k products, and a Shopify app running in production. ⭐ Checkout & Post-Purchase Extensions — React-based UI extensions, validation logic, Shopify Functions ⭐ B2B — company-scoped catalogs and pricing, purchasing-company logic, B2B-specific checkout targets ⭐ Metafields & Metaobjects — data architecture for large or messy catalogs, plus migration and cleanup ⭐ Theme Development — Online Store 2.0, Horizon, Liquid, sections and blocks built to be edited safely ⭐ App Development — Node/Remix apps, webhooks, deployed and maintained, not just prototyped ⭐ Design Execution — Figma to pixel-accurate implementation; responsive systems, typography, layout I'm most useful when something is broken in a way the theme editor can't fix, or when structure needs to be built correctly the first time rather than refactored later. I document what I hand off. Send me the requirement — checkout logic, a B2B rollout, a catalog that's outgrown its data model — and I'll tell you straight whether I'm the right fit for it.

Most Shopify stores doing $50k–500k/mo lose 15–30% of their revenue to problems the owner can't see. I find them, put a dollar value on each one, and fix them myself. $100K+ earned here across 84 contracts, 2,900+ hours, 100% job success. I've never left a client hanging. What I do now is narrower than what most of that history shows. Here's the gap I fill: Most CRO consultants can tell you what's wrong but can't touch your theme. Most Shopify developers can build anything but can't tell you what's worth building. I do both. 14 years of engineering, 6+ in Shopify (themes, Liquid, custom apps, Plus, headless/Hydrogen). I read the data, form the hypothesis, and ship the fix myself. WHAT I DO 1. Revenue Leak Audit: 72 hours I go through your store, analytics, speed data, and checkout flow. You get a 20-minute walkthrough video plus a written report: your top 10 revenue leaks, ranked, each with an estimated dollar value per year, the effort to fix, and the expected lift. 2. Conversion Sprint: 30 days I implement the highest-impact fixes, run A/B tests, and report before/after with real numbers. 3. Ongoing CRO retainer Continuous hypothesis → test → ship → report. HOW I PRICE RISK If the audit doesn't surface opportunities worth at least 5x its cost in projected annual revenue, you don't pay for it. TECHNICAL DEPTH Shopify (Liquid, Online Store 2.0, metaobjects, custom apps, Plus, Functions, checkout extensibility), Hydrogen/Oxygen, React, Node, GA4, GTM, Clarity, Hotjar, Core Web Vitals. Shopify Certified Developer. UTC-5, full US business-hours overlap. Fluent English, native Spanish. If your store has traffic and the conversion rate doesn't match it, send me the URL. I'll tell you what I see before you pay anything.
