Experience

  • PatchStyles
    https://www.npmjs.com/package/patch-styles

    A declarative way for patching styles and switching to CSS/SCSS modules with just a few lines of code in React. It's providing a single component to apply around your code and provides the classNames object; then, it will automatically apply the CSS/SCSS module to your React components.
    The traditional way has an issue with testing as you can assume that you need to use the same style for querying elements, but you shouldn't. With PatchStyles, you never change your className-s nor tests.

  • Caganddot

    This was a project for selling pets, pet food, or supplies. It was an eCommerce application with a simple eCommerce API and simple eCommerce UI. It also had Angular Universal implementation and was SSR rendering pages. The UI was using Angular Material, which was a bit modified to correspond to the design.

  • SmartSpending Extension

    This is a browser extension for Chrome, Firefox, and Edge which is showing you available offers on the retailer websites.
    First, you have to sign in to it with your RewardGateway account, and then it'll start showing you offer popup when you visit an online shop. For not being annoying the popups are being automatically snoozed for a while after first navigation on the website. You can manually un-snooze them by clicking on the extension icon when you're on the website and it'll show the offer popup again. Also, you can manage your account by visiting the extension's options page.

  • Ext JS Bundle Tool

    This is a bundling tool for Ext JS files that helps to optimize the speed of script loading of vROps (vRealize Operations). For a certain network connection, it optimized more than six times.
    Due to VMware's NDA policy, I can't share any link or a source for it.
