I studied various core concepts of programming and computer science, such as algorithms, network architecture, programming languages and artificial intelligence, while my focus was Software Technologies & Intelligent Systems. During this time, I learnt to code in C++, Java, C#, HTML, CSS, JavaScript, PHP and Prolog, developing various projects and applications, oftentimes integrating SQL databases. My thesis was on Business Process Intelligence, Process Mining and the ProM Framework (available here in Greek).

I studied Advanced Software Development Technologies, familiarizing with some more advanced programming and architecture concepts, especially ones that are used in web-based technologies and modern desktop applications. During this time, I explored web and mobile development, as well as UI/UX design in more depth, while I became more fluent in JavaScript and PHP and had a chance to work with Firebase and cloud patforms such as Amazon Web Services (AWS) and DigitalOcean. My dissertation was titled Design, Development and Application of Advanced User Interface Software for Web Applications (available here in Greek).

I am the co-founder of the 30 seconds team and original creator of 30 seconds of code, a curated collection of over 300 modern JavaScript snippets, that can be easily copied into any new or existing project. The project has over 100 contributors and 35.000 stars on GitHub, while most of its systems utilize continuous integration tools to streamline the build and update process of the project. It's currently one of the most extensive learning resources for ES6 on GitHub. My core responsibilites as a mainter include, but are not limited to:

• Development, Indexing, Unit-testing, Maintenance and Documentation of a JavaScript (ES6) Codebase
• Development and Maintenance of Automation Tools and Continuous Integration (Node.js, Travis CI, Codacy)
• Content Management, Website Administration and Development (Node.js, GitHub Pages)
• Social Media Management (Facebook, Reddit)
• Package Deployment (npm, VSCode Marketplace)

I am the co-founder of the 30 seconds team, the team behind 30 seconds of code, 30 seconds of CSS, 30 seconds of Interviews and 30 seconds of React. I help curate and maintain all of these projects to different extents, participate actively in their development and contribute content from time to time.

I am the creator and maintainer of mini.css, a minimal, responsive and easily customizable alternative to popular CSS frameworks like Bootstrap and Semantic UI. It utilizes modern technologies, techniques and design patterns, such as the Flexbox module, CSS variables and material design, while it's written in SCSS without the need for any Javascript code. It runs on most modern browsers and is actively maintained and updated frequently. It was also the basis for my Master's Dissertation, which explored the application of UI/UX design principles in web interface design.

I built the Node Static Page Generator as a simple tool for creating static websites. The tool supports static HTML generation from Markdown files and metadata injection via JSON files, while it allows users to fully customize it by tweaking its code. The project is not actively maintained anymore.

I built the mocka placeholder to be a very simple, yet elegant content placeholder, used to enhance user experience when a page is loading. Crafted with customization in mind, it is written in SCSS, can be altered easily to accommodate any and all needs and runs on all browsers. The project is not actively maintained anymore.

I built CodeIgniter RAP as a set of helper functions that can be used to create RESTful APIs using PHP. While built for CodeIgniter, these helper functions are not dependent on it, allowing it to be used with other frameworks. The project has been tested thoroughly and used on various college projects, but is not actively maintained anymore.

I built Bootstrap Extend as a simple extension of Bootstrap 3, adding certain new components that extend and enhance the framework's functionality. These components include lightboxes, toggle switches, collapse boxes and custom styles for some common elements. This project has been discontinued since the launch of Bootstrap 4.

I built the HTML5 Template Generator as a replacement tool for all the boilerplates available online, so that anyone can quickly and easily create a simple HTML5-compliant page, without having to go through all the boring stuff. It supports exporting the templates to Codepen and JSFiddle, as well as defining a plethora of properties and generating certain framework boilerplates. The project is not actively maintained anymore.

I have built various demos and toy projects over the years. Here are some of the most interesting:

• I've tinkered with progressive web apps for a long time, producing a handful of demos, such as Mock PWA, Autumn Blog and PWApp Demo.
• I have dabbled in WebSockets a little bit, creating Cows.js, a simple chat platform powered by React.
• One of my earliest demos is Starclock-js, a beautiful astronomical clock built with JavaScript/jQuery, HTML and CSS.
• I built Reactor back in the days before create-react-app was the de facto choice for kickstarting React projects. It's a simple set of Bash/Batch scripts for creating a React project without having to set up everything yourslef.
• I've tried my hand at simple interpreters and parsers, producing Parse-MD.js for Markdown and brainsource.js for brainf**k, both written in JavaScript.
• While my experience with Python is quite limited, I have created a few demos, such as Unscrape, a simple image scraper for Unsplash, and Multisort, a sort of joke sorting algorithm.

I actively participate in the Q&A site Stack Overflow and I currently have over 4000 reputation points and a bronze tag badge in JavaScript. Most of my questions and answers are in the JavaScript, HTML, jQuery and CSS tags. Some of my top answers include:

• What is the difference between window.customElements.define() and document.registerElement()
• Vertical line with dots in ends and between
• Making an alarm clock with date time
• Fetch request to local file not working
• Why does 1+ +"2"+3 evaluate to 6 in JavaScript?

I actively participate in the coding challenge website Codewars and I currently have over 2500 honour points (3kyu). Most of my Kata solutions are written in JavaScript and Node.js.

I am somewhat active on Hashnode, a social network for developers, sharing short stories and articles about my experience with certain tools and projects.

I have actively participated in Sphere Online Judgle (SPOJ) in the past, ranking among the top 5000 users, as well as CodinGame, reaching level 10.
