  • Magento 2 Front-end Optimization to Pass a Core Web Vitals Audit

    Optimized a large Magento 2 store so that it would pass a Core Web Vitals audit and achieve a good Google PageSpeed score. I implemented the following to achieve the goal:
    • Compressed fonts.
    • Minified and preloaded assets.
    • Preconnected origins.
    • Created critical CSS to eliminate render-blocking assets.
    • Deferred and delayed third-party scripts, such as live chat, tracking, and analytics services.
    • Eliminated theme layout shifts during page load.
    • Connected image compression service and configured CDN.
    • Configured varnish to minimize TTFB and set the leverage browser cache.

    Before implementing all of this on a real-world store, I had to do a lot of R&D because there are very limited resources that describe how to apply these techniques for Magento.

  • WordPress and Magento 2 International Site for Bulldog Skincare

    Migrated a Magento 1 site to a new Magento 2 build that was integrated within WordPress with 20+ store views for different countries. As one of three developers, I focused mainly on the front end, implementing the design for the category page, product page, some CMS widgets, and flexible content elements for WordPress. I also migrated a few modules from the legacy Magento 1 build.

  • Automated UI Tests for a Magento 2 Store

    The site had a poorly implemented legacy extension for privilege cards, which was developed by the previous agency. The client couldn't afford a complete rebuild of this extension, but any minor changes in the logic and UI of this extension caused complex issues and bugs. Therefore, the client wanted to raise the quality of testing before any live deployment.

    I designed and implemented a range of automated Selenium unit tests that used BrowserStack to emulate real user interactions with their Magento 2 site. I also created a single-page dashboard to track the execution and results of the tests. Organized as suites, their purpose was to check key user journeys: adding a product to cart, checkout, login and registration, and applying discount codes and privilege cards.

  • Data Migration from Magento 1 to Magento 2
