Most Shopify subscription problems aren't solved by switching apps. They come from billing logic, renewal workflows, and subscriber experiences that Recharge, Appstle, and Skio were never designed to handle at a custom level. That's specifically what I work on. What I specialize in: ✅ Custom subscription logic on Shopify - dynamic billing intervals, variable pricing rules, product swap and bundle subscription workflows, conditional renewal logic, and subscriber-specific discounts built against the Shopify Subscriptions API - not configured through an app's settings panel ✅ Shopify Checkout Extensions for subscription brands - subscription disclosure steps, upsell flows, custom field capture, and order validation using Checkout UI Extensions and Shopify Functions on Shopify Plus ✅ Recharge, Appstle & Skio integrations - connecting and extending these tools when their native functionality stops being enough, including webhook-driven workflows, custom subscriber portals built on top of their APIs, and migration between subscription platforms with zero renewal disruption ✅ Klaviyo & subscription workflows - renewal reminder sequences, churn triggers, win-back flows, and subscriber behavior-based automations wired directly into your subscription billing events ✅ Subscription UX on Shopify themes - subscription vs one-time pricing display, frequency selectors, subscriber account pages, and skip/pause/cancel flows built using Liquid and Shopify's Sections framework Industries I've worked in: - Pet food and pet supply (recurring delivery, frequency customization, multi-pet household logic) - Health and wellness (supplement subscriptions, compliance-aware checkout flows) - Coffee, beverages, and food (bundle subscriptions, flavor/variant selection, biweekly delivery logic) - Meal kits and consumables (skip/pause flows, complex fulfillment timing) - Digital memberships and access-based subscriptions How I work: Before touching any code, I map the subscription model - billing cycles, renewal state, edge cases, failed payment behavior - so the build reflects how your business actually operates, not a generic subscription template. I've been building ecommerce systems for 11 years. Subscription logic breaks in specific, predictable ways. I build to avoid them. If you're a Shopify subscription brand that has outgrown what your current app can configure, send me a message describing what you're trying to build. I'll tell you directly whether it's solvable and how. Tools & Platforms: Shopify Subscriptions API, Shopify Admin API, Checkout UI Extensions, Shopify Functions, Liquid, Recharge API, Appstle, Skio, Klaviyo, Stripe, Webhooks, JavaScript, Node.js
