Designer, developer & maker

Arne Hendriksen

Creator of Megaproductive, FollowerBase, Chiefly, Username Alert, and Startup ebooks. Publisher of KerstmisGids (Dutch). Former netlabel owner. Open source contributor. Small-scale investor in digital assets and web properties. Occasional home studio musician. Productivity enthusiast and GTD adept.

Started out as a designer, took an interest in development, and have been starting web/creative projects ever since. My constant drive to create and improve turned me into a maker and serial bootstrapper. I'm not available for client work.

Web and creative


I've built a diverse portfolio of web and creative projects over the years, ranging from niche blogs and communities, to products and services for internet entrepreneurs. Some have turned into small ventures while others remain active as pet projects.

Here is a selection of my most notable projects. For a more extensive list of past and present projects, see this blog post.


Think of Megaproductive as an Evernote for actionable and reference items. With tags, advanced search filters, and smartlists, Megaproductive aims to level up your daily workflow, and help you identify the things that actually need to get done.


Your follower base is composed of potential leads, existing customers, and brand ambassadors (fans). It's time you got the full details of the people and businesses behind your follower count (or your competitor's).

Username Alert

A simple service that lets you submit a username that’s currently taken, and will notify you whenever it becomes available on any of the social networks you've selected.

Startup ebooks

A curated list of ebooks about entrepreneurship, startups, and bootstrapping.

Doing my part


Part of being a developer is writing clean and reusable code. This is a trait I still think is underrated by many. Even in the early stages of building something new, I always look for pieces of code to refactor, reuse in other projects, and/or turn into stand-alone packages. Most of these packages get published to public repositories under an open source license.

Aside from contributing to the open source development community, I'm also actively involved in the maker community, and am occasionally asked to write guest blogs about productivity, personal development, and bootstrapping.

Open source

Composer packages

My public PHP packages are available from Packagist, and can be installed with Composer. These packages range from vanilla PHP helper classes, to packages that add functionality to Laravel applications.

Guest blogger


I've been asked to become a guest blogger for Go-getters, which is a soon to be launched Dutch blog, aimed at people determined to get the most out of life. It will feature hands-on tips and guides about productivity, online opportunities, entrepreneurship, and finance.

Let's get in touch

I love connecting with new people, so feel free to contact me and introduce yourself. The best way to contact me is either through Twitter or email.

Not available for client work

Although I'm quite the busy man when it comes to design & development projects, none of these projects are actually commissioned work. Due to a non-compete clause in my job contract, I am currently unable to provide web design services to prospective clients.
