Experience

Premier Lacrosse League, Inc.

https://premierlacrosseleague.com/
I worked on Premierlacrosseleague.com to enhance overall site performance, security, and accessibility. My 1st step was to thoroughly audit the site’s Shopify apps and remove all unnecessary or redundant apps that were slowing down the store and complicating maintenance. I replaced these with custom Shopify coding solutions to streamline processes and improve site efficiency. To make the website more inclusive, I focused on ADA compliance improvements, raising the accessibility score to 85 by addressing key accessibility issues such as keyboard navigation, color contrast, ARIA labels, and semantic HTML structure. I also integrated Single Sign-On (SSO) functionality to provide users a seamless and secure login experience across multiple platforms. Additionally, I identified and resolved several critical technical issues impacting website stability, checkout flow, and overall user experience. These combined efforts resulted in a faster, more accessible, secure, and user-friendly Shopify store, meeting business goals and user needs.

Erlinger Sales LLC

I enhanced the Chemical Warehouse Shopify store by resolving critical functionality issues and implementing advanced features to improve user experience and performance.

I optimized the product filtering system, ensuring accurate search results and enhancing discoverability. Additionally, I developed a custom checkout extension to streamline the purchasing process and fixed cart display issues for a seamless shopping experience. To improve search efficiency, I implemented multi-parameter search functionality, resulting in a 30% increase in successful searches. I also integrated dynamic product updates on the collection page, allowing automatic price and stock status changes based on variant selection and improving inventory accuracy. My expertise in Shopify development significantly enhanced the store’s usability, functionality, and overall efficiency, providing a smoother and more intuitive shopping experience for customers.

Soul Chocolate

https://www.soulchocolate.com
Engaged with Soul Chocolate and took their website to the next level.

I worked closely with their team to translate their design vision from Figma mockups into a user-friendly and engaging online experience.

My main goal was to make shopping on the Soul Chocolate website a breeze. This meant streamlining the checkout process, making product browsing and selection more intuitive, and offering a personalized touch. I redesigned product pages, collections, and the homepage to reflect Soul Chocolate's unique brand and the delicious chocolates they offer.

Throughout the project, I worked with the Soul Chocolate team to get their feedback and ensure the final website exceeded their expectations. Using my skills in web design and eCommerce development, I helped create a website that captures the essence of the Soul Chocolate brand and helps them connect with more customers and boost sales.

Root Plants

https://www.rootsplants.co.uk
I joined this project to address compatibility issues on the Root Plants website, particularly for Google Chromebooks.

Diving into the website's CSS and JavaScript, I identified and resolved any problems preventing optimal display across Chromebooks, devices, and browsers. I enhanced the blog and article pages to better reflect the Root Plants brand, ensuring the design aligned with their branding strategy and providing a more seamless experience for users.

Additionally, I spearheaded the development of a custom app for their Shopify store, allowing customers to easily track their order status directly from the order detail page without leaving the website.

Stealth Vision

https://stealthvision.com
My primary role was transforming the Figma design into a fully functional end-user experience. I implemented design elements across the homepage, product pages, and collection pages, focusing on enhancing the overall customer experience. This involved optimizing the layout, improving navigation, and integrating interactive features to engage users effectively.

I customized the product pages to showcase Stealth Vision's products in the best possible light, leveraging visual elements and interactive features to highlight key selling points.

In addition to the front-end enhancements, I addressed styling issues with 3rd-party apps integrated into the website. This involved debugging and refining the CSS to ensure consistency and alignment with the overall design aesthetic.

Just Thrive Health

https://justthrivehealth.com
Just Thrive Health is a project for which I contributed as a Shopify developer, leveraging my expertise to enhance the functionality and user experience of the eCommerce platform. My role encompassed a variety of responsibilities, beginning with direct client engagement to understand their unique needs and business goals. This collaborative approach ensured that every update and enhancement aligned with the brand's vision. I managed the Recharge app's subscription model, a critical component for recurring orders, by optimizing its integration and ensuring seamless functionality, improving customer retention and satisfaction. Additionally, I focused on Shopify theme customization to deliver a visually appealing and responsive design that resonated with the brand's identity while maintaining a user-friendly interface. Code optimization was another key area where I streamlined and refined the codebase to improve site performance, loading speed, and scalability. By addressing these elements, I was able to deliver a robust, efficient, and aesthetically pleasing online store that supports Just Thrive Health’s mission to provide wellness solutions to its customers.
