Janne T.

I build complete Shopify stores, rebuilds, and custom themes from supplied designs, wireframes, or HTML/CSS. I also provide ongoing technical care for existing stores, including custom Liquid functionality, app and theme troubleshooting, mobile UX improvements, performance work, and production-safe fixes.

You get a polished, responsive storefront built around usability, maintainability, and commercial goals. I create flexible Online Store 2.0 sections, blocks, and templates so your team can manage content through Shopify’s theme editor after launch.

I’m a Top Rated Plus Shopify developer with 70+ five-star Upwork reviews and experience across 90+ Shopify projects. I’m also a Shopify Partner with 20+ years in IT and a verified Liquid Storefronts for Theme Developers certification.

— HOW I WORK —
You work directly with me throughout the project. I remain responsible for scoping, technical decisions, communication, and final quality.
I clarify requirements, identify technical risks early, and explain trade-offs in plain English. Where appropriate, I use preview themes, version control, structured QA, backups, and rollback planning to protect the live storefront.
I also build for the people who will manage the store after handoff. When useful, I provide Loom walkthroughs and clear documentation so your team can confidently operate the finished solution.
