I'm Phil, founder of Candystore Studio, a Shopify studio. I've spent over 12 years building for the web and the last 6 on Shopify, including work for brands such as BrewDog, Hoodrich, Ooni and Vuse UK. Most of my work now is keeping Shopify stores working, secure and lean as brands do more themselves with AI tools and native Shopify features. Building a section with Sidekick or ChatGPT takes an afternoon. What takes the time is everything after: code that breaks on the next theme update, apps nobody remembers installing, scripts left behind by old apps, tracking that quietly stops. That is the part I take off your plate. In practice that means auditing what is installed and who has access, repairing and documenting AI-generated code, replacing single-job apps with native Shopify features or clean theme code, and monthly care for brands that want an expert watching the store. My core stack is Liquid and Online Store 2.0, JavaScript and TypeScript, and I work regularly with Klaviyo, Recharge, Rebuy, Algolia and Judge.me. When a project needs design or branding, Candystore's design team works alongside me. Every engagement starts with a fixed-price review and a written report you can act on with me or anyone else. Work happens on a duplicate theme and goes live only after your sign-off.

I am a frontend web developer with over 14 years of experience, specialising in Shopify and WordPress development. My focus is on building seamless, conversion-focused eCommerce experiences that combine clean design with high performance. I work with a modern tech stack that includes HTML, CSS, JavaScript (ES6+), Liquid, React, Tailwind CSS, and popular CMS frameworks. I am also experienced in integrating marketing tools such as Klaviyo, Mailchimp, and Google Tag Manager, helping brands automate and scale their online presence effectively. Some of the projects I am most proud of involve transforming underperforming storefronts into fast, mobile-first websites with measurable improvements in conversion rate and user engagement. My approach blends UX/UI enhancement, speed optimisation, and conversion rate optimisation (CRO) strategies to ensure every site not only looks great but delivers real business results. Whether collaborating with agencies or supporting in-house teams, I take a hands-on, performance-driven approach to development-turning creative ideas into high-impact digital experiences.
ShopiCraft | A Boutique Agency, Founded by a Former Shopify Employee I'm Daniel, and together with my co-founder Daulet, we run ShopiCraft — a boutique Shopify agency focused on solving the technical problems other developers won't touch. I spent years inside Shopify before going independent. Daulet brings 10 years of full-stack development experience from one of Europe's leading energy firms. Together, we help merchants turn their Shopify stores from basic storefronts into reliable revenue machines. We specialize in the technical work that sits between "good enough" and "actually scalable" — the custom apps, integrations, and automations that make your store work the way your business actually needs it to. What We Do: Custom App Development: Bespoke Shopify apps (public and private) built to solve specific workflow problems your business has outgrown. API Integrations: Complex third-party connections, ERP syncs, warehouse management systems, and custom data flows that need to just work. Store Builds & Redesigns: Full theme development, migrations, and rebuilds for brands ready to level up their storefront. Technical Consulting & Audits: Store performance reviews, app stack optimization, and strategic guidance on scaling your technical infrastructure. Automation & Workflows: Shopify Flow implementations, inventory systems, order routing, and multi-location logic that eliminate manual work. Training & Mentorship: Hands-on guidance for in-house teams learning to manage Shopify more effectively. How we work: Daulet handles all custom and public app development — the deep technical builds that require serious engineering. I handle client strategy, audits, consultations, store builds, and anything client-facing. This division means you get both: a developer who can actually build what you need, and a consultant who understands your business well enough to recommend the right solution. We work with brands that are either: Scaling quickly and need technical infrastructure that won't break under pressure Stuck with a Shopify setup that's actively holding back growth Tired of developers who disappear after delivery or agencies that can't execute custom work Our approach is different: We don't "sell" packages or push unnecessary apps. We diagnose what's actually broken, scope solutions honestly, and build things that last. No fluff, no vendor lock-in, no recurring retainers unless the work genuinely requires it. ShopiCraft is a boutique agency — which means you're working directly with the people who'll build your solution, not account managers reading from scripts. We focus on finding the most efficient, creative solutions to your specific pain points. If your developer ghosted you, your agency said "that's not possible," or you're pretty sure your store could do more but don't know where to start — that's exactly what we're here for. We're based in Dublin and Kazakhstan, working with Shopify and Shopify Plus merchants globally. Let's fix what's broken and build what's missing. 🔧

I’m a german Shopify developer with over 5 years of experience working on e-commerce projects. My work focuses on custom Shopify development, store optimization, automations, and SEO foundations. I build and customize themes and apps using Liquid, HTML, CSS, GraphQL and JavaScript, and I regularly work with Shopify Flow and n8n to automate workflows and connect external tools. Projects I’m especially proud of include custom Shopify theme builds, clean migrations from WooCommerce and Shopware, and automation setups that significantly reduced manual work for store owners. I value clean code, clear communication, and solutions that are easy to maintain and scale over time.
Checkout Plus projects that justify outside help
Each of these touches live orders, so mistakes show up as lost sales or support tickets, not as a broken layout.
Payment and shipping rules. Hiding a payment method for some carts, renaming a shipping rate, changing the order methods appear in. Every rule is a set of conditions, and one loose condition hides a method from everyone.
Order validations. Rules that stop checkout outright, such as an order over a quantity limit or one missing a required detail. They need a test cart for every edge case, because a false positive blocks a paying customer.
Upsells inside checkout. Warranties, shipping protection, gift wrap and auto-added gifts in the checkout steps. These need Shopify Plus and the Advanced plan. An expert decides which offer earns the space and where it sits.
Thank you and order status pages. Post-purchase offers and content on pages every store can edit. For a store not on Plus, this is usually the first project worth doing.
Fields and notes. Delivery instructions, gift messages, checkboxes and line item notes. Someone has to decide which are required and confirm the packing team sees the answers.
Brand styling. Checkout branding is on the Advanced plan. Matching fonts, colors and spacing to the storefront is standard checkout customization work.
A one-rule job. Hiding one payment method or renaming one rate is a few clicks in the app. Do it yourself and save the budget for the multi-condition setups.
How to pick a Checkout Plus expert worth the fee
A short call tells you most of what you need. Ask about your own store, not about checkout in general.
Ask what they can build on your plan. A strong answer splits the list without checking notes: rules, validations and thank-you page offers work on any plan, while upsells, fields and trust badges inside the checkout steps need Shopify Plus.
Ask how they test a rule. You want test carts for each condition, each market and each shipping profile, run before the rule goes live. "We'll watch the orders" is not a test plan.
Ask what else touches your checkout. Plus Apps says two apps that control the same payment methods, validations or offers can behave unexpectedly. A careful expert asks for your app list before quoting.
Signs they haven't used it. Quoting theme code edits for checkout, which the app doesn't need. Treating test carts as optional. Promising an in-checkout block to a store that isn't on Shopify Plus.
Pay for a contained first task. One payment rule and one thank-you page offer, each tested with real carts and written up with the conditions used. That shows how they document work you will maintain later.
If you need a block the app doesn't offer, that is custom development. Look at checkout UI extension specialists for that part.
Checkout Plus requirements and what uninstalling removes
Two gates decide every feature. Your Shopify plan and your Checkout Plus plan both have to allow it. Check both before anyone scopes the project.
Plus-only, inside checkout. Upsells, custom fields and checkboxes, banners, trust badges, free shipping progress bars, review widgets, delivery instructions and line item notes on the information, shipping and payment steps.
Any Shopify plan. Hiding, renaming and reordering payment methods, shipping option changes, order validations, the post-purchase upsell page, and thank you and order status page edits.
The free plan is for test stores. As of October 2026, the free tier covers development and staging stores only. Basic is $19 a month, Plus $49 and Advanced $99, with a 7-day trial. Yearly billing costs $168, $432 or $888.
No theme code. Plus Apps says the app works inside Shopify's checkout through the checkout extensibility framework, so checkout features don't require edits to your theme.
Uninstalling wipes the setup. All customizations and configurations are deleted permanently and don't come back if you reinstall. Checkout falls back to Shopify's standard version. Write down every rule before you remove the app.

Checkout Plus questions on plans, cost and other apps
Partly. Payment and shipping method rules, order validations, the post-purchase upsell page and thank you and order status page changes work on standard plans. Anything placed inside the checkout steps, such as upsells, custom fields or trust badges, needs a Shopify Plus store. The Basic plan at $19 a month is built around the features that work everywhere.
As of October 2026, Basic costs $19 a month, Plus $49 and Advanced $99, each with a 7-day trial. Yearly billing saves roughly a quarter. The free plan only covers development and staging stores, so a live store pays from day one. Any expert fee is separate and depends on how many rules and offers you need.
Usually, yes. Plus Apps says trouble starts when two apps control the same thing: both hiding payment methods, both validating orders, or both showing upsells on the same condition. Give each job to one app, then test a full order on every shipping method before launch.
Not for a few rules or a thank-you page offer. The app has a drag-and-drop editor and needs no theme code. Hire help when rules stack several conditions, when you sell in several markets or currencies, or when you are on Shopify Plus and want the checkout steps redesigned with offers and fields.
Your Shopify plan, the Checkout Plus plan you are on or considering, and a plain list of rules: which payment or shipping method, for which carts, in which countries. Add the offers you want shown, the discount codes you run, and every other app that touches checkout or the thank-you page.
