About

Me

I am a web developer with a focus on Minimalism, Sustainability and Free Open-Source Software. These three cornerstones help me build a product that is purposeful, functional and long-lasting.

I live in the Netherlands and enjoy greatly the natural expression of this earth (nature) and the essential human expression of vibration (music).

I practice Mindfulness (as in intentional sitting, walking, speaking, listening). I am a member of the Metal Business Club; what a great combination that is!

I am a proponent of Free and open-source software (FOSS) with which I have built this website. You can read more about this in the Software section.

Consulting

Sustainability is always on my mind. Minimalism in presentation (e.g. no pictures if not necessary, no clutter) can help with data load,improves performance and eye strain. Hosting that is carbon-neutral (at least) is always a plus and often overlooked.

Sustainable Web Strategy

I help create lean, efficient websites that minimize environmental impact. From reducing unnecessary assets to choosing eco-friendly hosting, I ensure your site is both effective and sustainable.

Accessibility & Inclusive Design

Ensuring your site is accessible to everyone is essential. I help you improve design for better readability, usability, and inclusivity, making sure your site complies with accessibility standards and is easy for all users to navigate.

Performance & User Experience Optimization

A slow, cluttered website frustrates users and drives them away. I analyze your site’s structure, design, and content to improve speed, clarity, and overall experience.

Design & Content Overhaul

If your website feels outdated or overwhelming, I help refine it—removing distractions, improving navigation, and creating a clean, focused design that enhances engagement.

Sustainability Report & Recommendations

I provide a comprehensive sustainability report that evaluates your website’s carbon footprint, energy consumption, and efficiency. This helps identify areas for improvement and ensures your digital presence aligns with sustainable practices.

Software

In current times, there is virtually an endless amount of technologies one can choose from. There is only the question: What do I know how to use and what do I need for this project?

Tech Stack (ioannishariskos.com)

Here are the technologies I used to create this website: Astro, Tailwind CSS, and Netlify. Not only are these some of the fastest technologies available, but they are also more sustainable (JAMstack) than traditional tech stacks.

Setup

I use software that follows the FOSS principles. Supporting these companies and communities ensures that the internet and computing in general stays a public good.
