Mykola S.

Shopify Developer | Speed & Conversion Expert | Functions + SEO

I build high-performance Shopify stores that hit peak performance targets and directly boost revenue for DTC brands. With over 6 years of frontend experience and 4+ years dedicated exclusively to the Shopify ecosystem, I turn complex Figma designs into scalable, pixel-perfect shops that load fast and convert. Proven Track Record: My approach combines technical excellence with a focus on business results. I maintain a 100% Job Success Score and have successfully delivered 33+ projects, ensuring that storefronts are not just beautiful, but also stable, secure, and high-converting. Expertise for Your Growth: Performance Optimization: I optimize Core Web Vitals (LCP lower than 2.5s, CLS lower than 0.05) within Shopify limits, ensuring your site passes speed audits even with heavy third-party apps. Advanced Shopify Development: Using Shopify Functions, Liquid, and Shopify APIs (Admin and Storefront), I build custom sections, smart discounts, and checkout customizations without the bloat of unnecessary apps. Custom OS 2.0 Themes: I create responsive, maintainable themes from scratch or Figma, utilizing clean SCSS and JavaScript for a unique and fast user experience. Seamless Integrations: I handle complex migrations and setups for Recharge Subscriptions, Klaviyo Automation, and Yotpo Reviews, ensuring your tech stack works perfectly from day one. Technical Mastery: My workflow is built on modern standards: Liquid (Advanced), JavaScript (ES6+), and GraphQL. I use Shopify CLI, GitHub, and Vite/Webpack to deliver professional-grade code that is easy to manage and scale. Ready to scale your store? Message me with your URL, and I’ll tell you if your current theme can hit sub-2s loading times. Let’s turn your visitors into loyal customers!
