Shopify Speed Optimisation Expert | Checkout Flow Specialist
Odogbolu, Nigeria - 2:24 pm local time
If you’re browsing Upwork trying to find the one not romantically, but the Shopify expert who gets what your store actually needs you have just landed in the right place.
Hi, I’m Olasubomi, a Shopify design and development expert with 5+ years of hands on experience helping brands (from scrappy startups to 7-figure E-Com machines) build, fix, redesign, and optimize their online stores.
No cookie cutter builds here. I treat every store like a living brand with its own voice, goals, and audience behavior. I dive deep into what makes your customers click, scroll, and buy, then craft a storefront that does what you hired it to do: convert.
💼 Services I Offer:
🎨 Shopify Design & Redesign (UX-Driven)
From-scratch builds & theme customizations
Mobile-first layouts designed to convert
Speed-optimized, branded UI with pixel-perfect detail
Custom code tweaks (Liquid, JS, CSS/HTML)
📈 Conversion Rate Optimization (CRO)
UX audits that go beyond it looks fine
Funnel fixes, product page enhancements, improved navigation
Reduce bounce, raise AOV, and increase add-to-cart flow
🛠 Ongoing Store Support & Maintenance
Troubleshooting themes, apps, bugs
Product uploads, inventory updates, app reviews
Monthly retainers available
🔌 App Integration & Tech Stack Setup
Loyalty, reviews, upsells, payment gateways & more
Expert app selection for speed & ROI
Clean installations that won’t tank your load time
🔄 Shopify Migrations
From WooCommerce, Etsy, Wix, Squarespace & custom platforms
Smooth transitions with no SEO panic
Data mapping, redirects, content styling, launch support
👥 Who I Work With:
DTC brands in beauty, fashion, wellness, pet, home & lifestyle
Startups needing a reliable, scalable launchpad
Agencies looking for a white-label Shopify pro
Established brands tired of mediocre performance
📊 Recent Wins:
Helped a beauty brand increase AOV by 28% with checkout & UX fixes
Migrated a crafts brand from Etsy and doubled sales in 6 months
Rebuilt a sluggish fashion store → +40% site speed → higher engagement
Manage seasonal updates for multiple stores on monthly retainers
