Mykola Havrylov

Shopify Developer with 4+ years on the platform and 8+ years in web development. I own the full storefront cycle — from Figma and pixel-perfect Liquid implementation on Online Store 2.0 to GitHub-based deployment and performance optimization.

Improved Core Web

Vitals (LCP, CLS, INP) by 30–40% across projects and contributed to 15–20% organic traffic growth on high-traffic stores. I also replace paid third-party apps with native Metafields and Metaobjects logic — fewer dependencies, lower recurring cost, faster storefront.

Former Team

Lead of 4–6 developers: I write code other people can maintain, and I review theirs.

Shopify Developer — Independent Contractor (B2B) at Self-employed (2026-01 – Present)

Ongoing Shopify work under NDA through long-term B2B contracts. Client names and identifying business details are confidential; technical scope and implementation decisions can be discussed during an interview.

• Leading a legacy theme migration to Online Store 2.0 alongside a complete storefront redesign, replacing an unmaintained Theme Kit and Vue 2 build.
• Replaced a paid custom-fields application with native Shopify Metafields and Metaobjects via the Admin GraphQL API, removing a recurring subscription and an external dependency from every page render.
• Introduced Git-flow and Shopify GitHub integration on a store previously edited live: branch-based development, code review and safer releases.
• Refactored legacy frontend code and improved image loading, theme performance and long-term maintainability.
• Developed new storefront functionality, Shopify Flow automations and custom Liquid email templates for a subscription-based e-commerce project.

Shopify Developer / Frontend Developer at Gelt.Biz (2023-03 – 2025-12)

• Architected scalable Shopify storefronts on custom Liquid themes built from Dawn, using Sections Everywhere, Metafields and Metaobjects so content teams could ship without a developer.
• Improved Core Web Vitals (LCP, CLS, INP) by 30–40% across 3 projects through code splitting, critical CSS extraction, WebP and lazy-loading image strategy, and legacy JavaScript refactoring.
• Connected Shopify stores to GitHub for version-controlled theme development, introducing branch-based workflow and code review in place of editing live themes.
• Built complex interactive storefront components with GSAP and Styled Components for product and campaign landing pages.
• Developed quiz funnels in GoHighLevel integrated with Meta Pixel and custom conversion events, giving marketing accurate campaign attribution.
• Built custom WordPress themes from scratch with Sage (Roots.io), Blade and ACF, following a Figma to markup to theme workflow.

• Optimized high-traffic e-commerce sites for technical SEO (structured data, page speed, Core Web Vitals), contributing to 15–20% organic traffic growth across key accounts.
• Resolved critical issues across 6–8 concurrent Shopify projects under tight deadlines, maintaining a consistent on-time delivery record.
• Mentored 3 junior developers from onboarding to independent delivery within 3–4 months.
