Hi there, my name is Janaka. I'm a full-stack web developer currently living in Melbourne, Australia. I am passionate about building beautiful, interactive web applications with the best user experience. Besides the web, I'm interested in new technologies and DIY activities, mainly 3D printing and CNC-related projects.

I was born in Sri Lanka and moved to Melbourne in 2022. I earned my bachelor's degree in Chemical and Process Engineering. After graduation, I worked as a chemical engineer in the sugar manufacturing industry, where I held an executive role focused on workforce management and decision-making.

During the pandemic, I started learning to code with Java and then followed the online CS50 course at Harvard University. After moving to Melbourne, I joined Le Wagon coding bootcamp to broaden my skills. After working as a freelance web developer for one year, I decided to do my master's in Business Information Systems at Torrens University Australia to fill gaps in my business, project management and IT skills.

I primarily use Ruby on Rails for building full-stack web applications and React/Redux or vanilla JavaScript for front-end development. If you plan to build a web application, collaborate on something cool, or want to say hi, shoot me a message. Let's work together!

          My Portfolio Website

          My first personal portfolio website.

          This is the first version of my portfolio website. I created it using just HTML5, SCSS, and some JavaScript. All components and sections were designed and developed from scratch with plain HTML and CSS. My main goal was to build a fully responsive, accessible and high-performance website. Below is a screenshot of the Google PageSpeed Insights of this website.
