Terrible job with the website. I could’ve done better myself and for what I paid I feel robbed. They also managed to take a domain I had registered that I will get back

Job Success
Mohali, India - 9:09 am local time
I am a Shopify Plus Developer and Certified Shopify Partner with 10+ years of experience, 13,000+ hours on Upwork, 100+ five-star reviews, and $300K+ earned building and rebuilding Shopify stores for brands and agencies across Canada, North America, Europe, and Australia.
Every store I build or redesign is engineered for two things: clean code that performs and a user experience that converts. Not one or the other.
Custom Shopify Theme Development
New stores built from scratch using Figma, XD, or PSD files. Full Shopify 2.0 architecture with dynamic sections, blocks, metafields, and content-managed layouts. Pixel-perfect execution with clean, documented Liquid code your team can maintain after handoff.
Shopify Store Redesign and Revamp
Existing stores that have outgrown their current theme, look outdated, or underperform on mobile. I rebuild them with better UX structure, faster load times, and product page architecture designed to reduce drop-off and increase purchase confidence.
Shopify Plus Development
Checkout extensibility, Shopify Functions, Flow automation, B2B storefront configuration, multi-store setups, and custom scripts for brands on the Plus plan.
Figma to Shopify
If you have a design file, I build it exactly. Figma, XD, or PSD — complete translation from design to live Shopify theme without the revision cycles that turn a clean brief into a long project.
Shopify App Development and Integrations
Private Shopify app development, REST and GraphQL API integrations, and third-party app setup: Klaviyo, Yotpo, Recharge, Judge.me, Bold, and Gorgias.
Who Works With Me
Agencies who need a reliable senior Shopify developer for client builds — clean code, on-time delivery, no hand-holding required.
DTC brands with a Figma file who need a developer who executes it exactly the first time.
Shopify Plus brands building complex stores, launching B2B channels, or needing custom checkout functionality.
Store owners whose current theme is outdated or no longer matches their brand.
How I Work
I review requirements, ask the right questions upfront, and give you a realistic scope and timeline before work begins. Clean code. Clear communication. Documentation on delivery. No disappearing mid-project.
Share your design files or project requirements and I will send a direct scope assessment within 24 hours.
