Turning Shopify traffic into profit through Conversion-optimized Landing Pages, CRO strategy, and offer-driven design that scales DTC brands. ⚠️ Your store probably doesn’t have a traffic problem, but has a conversion problem. You’re paying for clicks, but too many leave without buying. That’s where my work comes in. I build Shopify Landing Pages, Product Pages, and Funnels that turn paid traffic into profit. Everything is built around CRO, offer-driven design, and real buyer psychology. Landing Pages that don’t just look clean but actually convert. Over the past few years, I’ve helped Shopify brands generate $325M+ in new revenue, double their conversion rates, and get more profit from the same traffic. When we work together, you get landing pages that: • Match your ad promise and stop revenue leaks • Build trust fast and move visitors to checkout • Are tested and optimized for real performance • Give your brand a clear, conversion-focused framework for growth If you’re ready to scale your Shopify store with pages built to convert, not just look good - let’s make it happen. 💬 Send me a message and let’s turn your traffic into consistent, scalable revenue!

I am a front-end developer with over 10 years of experience working with startups, solo founders, and small businesses. I help turn ideas and designs into clean, responsive, and reliable Shopify stores that look good, work smoothly, and grow with your business. My focus is on the front-end and technical side of Shopify — from full theme builds to adding custom sections, landing pages, features, and improvements to existing stores — making sure everything feels solid, consistent, and works well across all devices. ➤ WHAT I DO • Custom Shopify theme development – Build themes from scratch or from a starter theme based on designer mockups or requirements. • Theme additions, landing pages & feature development – Add custom sections, landing pages, theme features, layout changes, and front-end functionality to existing stores. • Store setup & full Shopify builds – Set up new stores end-to-end, from structure and theme implementation to launch-ready polish. • App integration & front-end customization – Integrate third-party apps and adjust the front-end so everything looks and works as expected. ➤ A FEW NOTES • I focus exclusively on Shopify front-end development and theme work — I don’t offer SEO, marketing, or copywriting. • If your budget allows, I recommend hiring a UX/UI designer. This leads to cleaner layouts, stronger visuals, and better brand recognition. • For tighter budgets, I can start from a premium or free Shopify theme and customize it to fit your brand and goals. This approach is more budget-friendly and lets you get your store up and running more quickly than a full custom build. I focus on making Shopify stores that are clean, reliable, and easy to grow. Whether it’s a full build or adding new features to an existing store, I’d love to help bring your ideas to life.

My Work Approach: Understanding Requirements: I begin by thoroughly understanding the project requirements, design specifications, and any additional functionalities. Clear communication with the team and stakeholders is crucial to align expectations and plan the development phases. Development Best Practices: I adhere to coding standards and best practices, such as modular coding, proper indentation, commenting, and naming conventions. Using Git for version control ensures that every change is tracked and can be reviewed if needed. Comprehensive Testing: I employ a multi-faceted testing strategy, including: Integration Testing: Ensuring that different modules and components work together seamlessly. Cross-Browser Testing: Testing the website across multiple browsers to ensure compatibility and a consistent user experience. Mobile Responsiveness: Rigorously testing the design on various devices and screen sizes to ensure it is fully responsive and mobile-friendly. Manual Testing: Performing extensive manual testing to catch any edge cases or user interface issues that automated tests might miss. Performance Optimization: I use tools like Google PageSpeed Insights and Lighthouse to check and optimize the performance of the website. Image optimization is also crucial, ensuring all images are web-optimized without compromising quality. Code Review and Collaboration: Peer code reviews are an integral part of my process. This helps in getting feedback from other developers and catching potential issues early. Collaboration with designers ensures that the implementation matches the design specifications accurately. User Acceptance Testing (UAT): I involve stakeholders in UAT to ensure the final product meets their expectations and requirements. This step is crucial for validating the user experience and making necessary adjustments before deployment. Final Checks and Deployment: Before the final deployment, I use a comprehensive checklist to verify that all aspects of the project have been addressed, including functionality, design, performance, and SEO. The code is first deployed to a staging environment to test it in a production-like setting. Continuous Improvement: Post-deployment, I gather feedback and monitor the website for any issues. This feedback loop helps in making continuous improvements and ensuring the website remains optimized and functional. Let's Connect!
