Super Malter | Top 5% of Malt freelancers
I am Wilfried Djossi, an expert Shopify and frontend developer specializing in Liquid, custom themes, technical SEO, and performance.
I assist brands and agencies on demanding Shopify projects: technical redesign, SEO optimization, advanced feature development, and performance improvements — with a strong focus on results.
What I do concretely
Development of custom Shopify themes (Liquid, sections, architecture), frontend integration of advanced designs, technical SEO optimization (Core Web Vitals, indexing, structure), clean and maintainable architectures, technical maintenance and evolution.
I do not work on simple projects. I intervene when the theme reaches its limits, when performance impacts revenue, or when custom solutions become necessary. Objective: fast, stable, conversion-oriented stores — without technical debt.
Experience with technically demanding projects, including a strategic migration for Davidoff involving a complete redesign and performance optimization.
I challenge you… to challenge me.
