Hire the Best Shopify Developers in Illinois

Hi, I'm Jakub a Shopify developer and designer with over 5 years of experience helping brands launch and scale their eCommerce stores. Whether you’re starting from scratch or want to optimize an existing store, here are some: 🛠 Common Problems I Help Solve ❌ Tired of developers breaking your site with every update? ✅ I build your store with fully automated testing scripts so updates don’t break anything. Ask your current developer if they write tests for Shopify. ❌ Is your website loading slow? ✅ I optimize image formats and use smart caching to consistently get load times under 1 second. ❌ Website broken or messy on mobile? ✅ Most of your traffic is mobile. I make sure your store looks and works great on every device and browser. ❌ Too many third-party apps making your site look off-brand or bloated? ✅ I have my own prebuilt custom solutions that I can quickly brand for your store. This saves you money on subscriptions and keeps everything consistent. ❌ Low conversion rates? ✅ Are you using aftersell offers? Klaviyo email flows? Abandoned cart recovery? A/B tests? I can give you a full plan to improve every step of your funnel. ❌ Overwhelmed or unsure what to do next? ✅ Along with development, I bring experience working with teams running Shopify stores that generate over $1M in annual revenue. I can help you prioritize and improve how your team operates. 🥇 Achievements & Highlights 🥇 Designed Kickstarter assets for SeatMate: (can send links)   • Split Ottoman Dog Ramp – raised $274,620   • Pet Office Furniture with Ramp – raised $488,623 🥇 Boosted conversion rates for Shopify stores with $1M+ yearly revenue (active clients) 🥇 Active Upwork Shopify contract with over $10,000 in billing   • See In Progress Tab below   • Website Rebrand + Conversion Rate Optimizations 🥇 5 years as a developer with thousands of commits annually (GitHub Jakub003) 🥇 Top Rated on Upwork ⭐ (see blue badge) 🥇 Known for above-and-beyond service with 100% success score (check feedback & reviews) 🥇 Worked on 100+ eCommerce projects (portfolio link available after message) 📩 Send me a message and I’ll give you a complimentary audit of your store, including actionable improvements you can make yourself to increase your conversion rates.

Your Shopify store is often the first impression customers get of your brand. It should look premium, be easy to navigate, and give you the flexibility to manage it yourself after launch. That’s what I help businesses build. I’m a Shopify Designer & Developer with 10+ years of experience creating custom, conversion-focused stores from design through development. I start with the design, not the code. I first create your store in Figma so we can work through the layout, visual direction, and user experience before development starts. You can see how everything will look, give feedback, and make changes before we move into Shopify. Once the design is approved, I build it on Shopify 2.0 using clean, modular sections and blocks. The goal is to give you control over your store after launch. You’ll be able to update content, replace images, and rearrange sections directly through the Shopify Customizer without needing a developer for every small update. I also work with existing designs. Whether you have a Figma file, PSD, or static HTML/CSS design, I can turn it into a pixel-perfect, responsive Shopify store while keeping the original design and functionality intact. I also use Shopify’s AI tools when they actually make sense for the project. Shopify Magic can help speed up product content and copy, AI-assisted design and image tools can reduce repetitive work, and AI-powered product recommendations can make it easier for customers to discover relevant products. The goal is to use AI where it adds value without making the store unnecessarily complicated. Recent Projects QualityDoor Shopify Plus - Converted the existing design into a pixel-perfect Shopify Plus store, rebuilt product pages and navigation, and organized the theme into clean, editable sections. bouff - Built the store from Figma into a responsive Shopify 2.0 site with modular sections that the client can easily manage without editing code. I’ve completed 268+ Shopify projects on Upwork, with a 99% Job Success Score and Top Rated Plus status. I’ve worked with startups, DTC brands, and established businesses on both new stores and existing Shopify stores that needed a redesign or modernization. What I do best: • Figma to Shopify, PSD to Shopify & HTML to Shopify • Custom Shopify & Shopify Plus theme development • Shopify Liquid, 2.0 sections, metafields & custom functionality • Modular sections and blocks that are easy to manage • Premium UI/UX design focused on usability and branding • Shopify AI tools, content assistance & product recommendations • Full Shopify store redesigns and customer journey improvements • App integrations and advanced Shopify features • Landing pages and conversion-focused layouts • Ongoing Shopify maintenance, updates & support I don’t believe every brand needs the same template or approach. I first understand your brand, products, and customers, then design and build a Shopify store around them. If you need a Shopify designer and developer who can take your idea from design to a polished, manageable store, feel free to reach out and tell me about your project.

I help ecommerce brands build Shopify stores that are not just visually polished, but structured to convert traffic into revenue. Most freelancers are strong in only one area. They can either design, or develop, or give general advice. That usually creates problems: - weak UX - slow execution - poor communication - messy theme setups - app bloat - stores that look fine but do not convert I solve that by combining Shopify development, conversion-focused design, and CRO thinking in one What I help with: Shopify design and development: - Full Shopify store builds - Shopify redesigns - Theme customization - Custom Shopify sections and templates - Shopify 2.0 / OS 2.0 builds - Figma to Shopify implementation - Landing pages for paid traffic - Product page and collection page optimization - Mobile-first UX improvements - Speed and performance optimization CRO and ecommerce optimization: - Conversion-focused homepage, PDP, cart, and checkout improvements - AOV optimization with upsells, bundles, subscriptions, and offers - Better customer journeys for cold traffic - Trust-building UX and messaging structure - A/B testing strategy and implementation - Heatmap and analytics-based improvements - UX audits and prioritization roadmaps Shopify migrations and technical work: - WooCommerce to Shopify - WordPress to Shopify - Wix to Shopify - Theme reworks and rebuilds - Catalog-heavy stores - Multilingual stores - Subscription flows - App integrations - Klaviyo, reviews, loyalty, subscriptions, tracking, and upsells - Ongoing Shopify support and maintenance What makes me different: I'm not a generic freelancer I specialize in Shopify ecommerce growth. That means we think beyond visuals: - how users navigate - where they drop off - what causes hesitation - how to improve trust - how to increase add-to-cart rate - how to improve conversion rate and AOV - how to build a store that is easy to scale and maintain I have worked with brands ranging from early-stage startups to established 7- and 8-figure ecommerce businesses. Clients usually come to me when: - their site looks outdated - conversion rates are low - mobile experience is weak - the current theme is messy - previous freelancers left technical debt - they need a store that feels premium and performs well - they want a team that can actually execute without hand-holding The process We use a structured process designed to reduce risk and keep projects moving: 1. Audit the current store, goals, and bottlenecks 2. Define the UX, CRO, and development priorities 3. Design and build with scalability in mind 4. QA across devices and browsers 5. Launch cleanly and support post-launch improvements You get clear communication, professional project management, and a team that knows Shopify deeply. I'm a strong fit if you need help with: - Shopify store setup - Shopify redesign - Shopify CRO - Shopify landing pages - Shopify theme development - Shopify product page optimization - Shopify migration - Shopify subscription setup - Shopify app integrations - Shopify speed optimization - Shopify UX/UI improvements - Shopify support and maintenance If you are tired of hiring freelancers who only solve one part of the problem, let’s talk.
