What I teach and Learn

In the large JavaScript Ocean, I am exploring few of the Islands. On my way, I love to guide through those islands for beginners and professionals

  • HTML, CSS and Everything

    User interface is an art. HTML5 and CSS3 are the tools to create UI for web. Most web developers start their learning journey with HTML and CSS. Its easy to learn HTML and CSS, but takes a lot of practice to master this art.

    HTML, CSS and Everything
  • JavaScript++


    JavaScript world has grown into an multi-verse. You can create any kind of applications targeting desktop, web and mobile using JS. Lot of people have JS fatigue too due to number of frameworks and libraries in JS πŸ˜‰

    Ease of development and maintainability is the key for software development. React has been the game changer in developer experience. More and more developers are learning react based web and mobile stack to boost up their career opportunities.

    Flirting with Native

    I use both react native and flutter for mobile development, I love both and felt flutter is better in some aspects. But so far, I have released only react native apps to production. Love to learn more and teach more in mobile development through React Native and flutter 😎

  • Gatsby Party

    Isn't Gatsby belongs to React ecosystem? Yes it does. But I want to keep a special mention for this awesome framework. Gatsby along with headless CMS will replace a lot of traditional decades old websites very soon. Oh boy, this is just a leaf out of whole Gatsby plant, I can't wait to see when the plants becomes a beautiful garden.

  • Django++ for rapid prototyping

    Django++ for rapid prototyping

    I believe in horses for the courses, if there is a requirement for rapid prototyping for basic rest API or website. I prefer Python / Django over JS based stack. After all, tools are chosen based on what we want to accomplish 😊
