Shopify Developer | Liquid, Custom Themes, Klaviyo & CRO

I help ecommerce brands build, fix, and optimize Shopify systems—from custom Liquid development to Klaviyo automation and conversion improvements. If your theme limits the customer experience, an integration is unreliable, or your store receives traffic without converting effectively, I can identify the technical and customer-journey problem, define the scope, and implement a maintainable solution. SHOPIFY DEVELOPMENT - Custom theme development and theme customization - Shopify Liquid, HTML, CSS, and JavaScript - Reusable sections, blocks, templates, and storefront features - App, API, and third-party integrations - Technical fixes, responsive improvements, and maintenance - AI agent and ecommerce workflow integrations KLAVIYO & RETENTION - Shopify–Klaviyo integration - Welcome, abandoned cart, browse, post-purchase, and win-back flows - Signup forms, pop-ups, segmentation foundations, and testing ECOMMERCE OPTIMIZATION - Shopify store and conversion audits - Product-page, navigation, cart, trust, and mobile UX improvements - Analytics readiness and prioritized growth roadmaps ECOMMERCE MARKETING STRATEGY - Shopify marketing strategy: positioning, channel priorities, and growth roadmaps - Aligning marketing plans with what the store and tech stack can actually support - Email/retention strategy alongside acquisition efforts, so campaigns and flows work together - Prioritized recommendations based on business goals, traffic, and available data HOW I WORK 1. Clarify the business goal, user problem, and technical constraints. 2. Define deliverables, access, dependencies, and acceptance criteria. 3. Build or optimize in a controlled environment. 4. Test, document, and hand over clearly. I'm best suited to clients who value sound implementation, thoughtful communication, and long-term maintainability—not shortcuts or unsupported guarantees. Send me your store URL, the problem you want solved, and your desired timeline. I'll reply with the most practical next step and any questions needed to scope it correctly.
