PROFESSIONAL SUMMARY

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)
Self-employed · Remote · 01/2026 – 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
Gelt.Biz · Warsaw, Poland · 03/2023 – 12/2025
• 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.

• Delivered custom Shopify themes from scratch across multiple client projects, including multi-language stores, RTL layouts and
Shopify Plus-specific features.
• Promoted to Team Lead: managed 4–6 developers, introduced Git-flow standards and code review, reducing critical bug rate
by approximately 30%.
• 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.

Web Developer (Part-time)
Software Development Hub · Kharkiv, Ukraine · 05/2017 – 07/2020
• Built responsive admin panels and CMS interfaces integrated with Django templates, ensuring cross-browser and pixel-perfect

SELECTED PROJECTS

• Legacy to Online Store 2.0 migration — replaced a Theme Kit and Vue 2 build with OS 2.0 architecture, a full redesign and
GitHub-based CI/CD on a live storefront.
• App to native Metafields migration — rebuilt a paid custom-fields app's data layer on native Metafields and Metaobjects via
the Admin GraphQL API; recurring cost eliminated.
• Shopify Flow email automation — event-driven transactional and marketing email system with custom Liquid templates for a
