The product

Jiffy Shirts is a U.S. based e-commerce company for blank apparel and custom printing. They sell DTF transfers, stickers, and on-demand printed goods to creators, small businesses, and enterprise clients.

Fast fulfillment and clear pricing are a big part of the product. Customers browse the catalog, customize items, and checkout with upfront costs and delivery timelines.

I worked on the Rails+Vue frontend across catalogs, customizations, cart, checkout, accounts, and print workflows.

Live store work

My responsibility varied from fixing bugs on the live store, where broken UI or wrong prices could block purchases, to building new features for the product catalog and checkout flows.

I traced pricing mismatches across product and checkout flows where the price on screen did not always match what customers were charged. After finding the bad state handling, I shipped a fix so pricing matched from the product page through checkout.

I also fixed cross-browser rendering and responsive layout bugs by reproducing issues in specific browsers, tightening layout rules, and checking fixes across viewports.

I built the cookie consent banner for production so it met compliance rules without getting in the way of browsing or checkout.

Outcome

I cut down layout shift on product pages by fixing how content loaded in. Pages stopped jumping around as images and prices appeared.

I removed old A/B experiment code from the product detail page. That cleaned up the PDP and made later changes easier.

I added analytics and event tracking so product and marketing could track key flows. I also updated the company blog theme, built a responsive footer, and fixed mobile layout issues on several templates.

The stack is a Rails app on the backend with JavaScript, TypeScript, Vue, SCSS, and Tailwind on the frontend. I added stable data-testid attributes for automation and worked with CI/CD review environments and QA before shipping to production.

The frontend is in better shape for day-to-day work and holds up better on mobile.
