James Hudson
I'm a freelance software developer and consultant based in Berlin. I work on complex, challenging, interesting, and worthwhile projects.
My Software Development Work
I've been doing freelance software development and consulting for about 15 years; for big multinationals, small companies, and individuals.

New technology opens up new opportunities every day; billion-dollar companies can now be run by a handful of people. A small, talented, specialist team can often outperform a large, traditional organization.

The world is filled with frustrating amounts of inefficiency and bureaucracy. Yet, in my experience, the latest technology can roughly double software productivity every year. This can also work for your business, in ways you might not have considered. By riding the wave of the current technological revolution, life can be made easier, happier, less expensive, and simpler, with surprisingly little effort. My customer's dreams are regularly manifested in a day; or for the really ambitious ones, a week.

To keep myself, and my customers, competitive, I work across a spectrum of technologies. I do everything from robotics to web development. I've built social networks and operating system components used by millions of people. However, I tend to specialise in graphics and multimedia.

Let's write a proposal together!

If your expertise is in something other than software, I'll work with you to select the right technology and design for your project and budget. I can also help with the technical aspects of your sales and marketing. Your "specifications" can be as little as the expression of a desire to "make something cool".

How I help you

You know your own business well, so I listen and learn in order to create something that helps you to do what you do, better. I think projects should be undertaken with as little waste of time and resources as possible, with stress-free customers and a great final creation as the goal throughout.

My engineering philosophy

The major problems which remain in software development are not technical, but organisational and social. A great product is made by considering the needs of the customer, the end users, and the developers who will maintain the project in the future. Even the best-programmed piece of software in the world would still be a failure if it didn't serve the needs of those who used it and paid for it.

A well-engineered product, whether it is a piece of software, a mechanical device, or anything else, is one which can be clearly broken down into its individual parts. Changes in one module should not require changes in others.

My Blog

I blog about how to get out of the daily grind, start your own business, and do better and more meaningful work. Some of the posts have led customers to me; so yes, the written word is still as important as ever in these days of newsfeeds and TL;DR!
In the News

Why I'm Happy
  • January 2018 - another year, another range of new skills gained. In 2017 I was developing commercial Linux hardware drivers and programming IoT devices over different networks. Now I am training up in Haskell and Ethereum dapp development to meet the extra opportunities that 2018 will bring.
  • December 2017 - I've had over 600 000 downloads of my personal apps.
  • September 2016 - ST VITO. Our technology/music/dance project got accepted into the Telekom Fashion Fusion program! So that means working with lots of good people to develop the project even further, and get it in front of a wider audience! I'm not mostly working on my own any more: we have an amazing, talented team! We've updated our costumes and concept with the help of the brilliant fashion designer Jasmin Lepore - we now have the most advanced LED costumes in the world (that I've seen)!
  • People are actually reading my blog about starting your own business! Find out how you can start doing what you want to do, instead of being told what to do by someone else.
  • Hands-free Browser App Store rankings:
    • Overall top 5 in 6 countries.
    • Utilities top 10 in 18 countries: top 5 in France, top 20 in Germany, France, Belgium, South Africa, South Korea.

  • My customers are really nice.

Technology Available for Events
Here are some projects I'm involved in which can be booked for events, conferences, workshops, or parties.


We've been taking this project around the world for performances, conferences, and parties. We bring together dozens of great media artists and performers, wherever they are in the world, to showcase the most thought-provoking, beautiful, and entertaining corners of the internet. The WJ-S system is a hardware and software installation which we set up at a venue. The system connects to a software service which allows performers from around the world to control the visuals and sound in the space.

Our project 111oOzOo111 has just finished 6 months of touring around France. It's a massive wall of recycled PCs and screens which brings the best of glitch art, net art, and lolcats, into a gallery context.



ST VITO is a multimedia performance project produced by Alma Edelstein-Feinsilber and James. It fuses live music, visuals, sensor technology, audience interaction, dance and theater into site-specific and walking-act performances. We are a group of professional artists, dancers, musicians and technicians. We reach out to the audience, letting them share the excitement and playfulness of public performance. By interacting with us physically, the audience becomes part of the creative process.

The Skin Orchestra project (the original skin touch sensor technology for ST VITO) is a collaboration between Alma Edelstein-Feinsilber, James Hudson, and Patricio Zarazaga.

The Novel
I've written a novel - The Disconnectionist.

A parable for our technological era?

Or an apocalyptic road-trip of mayhem, sex, love, and martial arts?

As a young warrior-priest in an idyllic mountain monastery, Cade longs to possess the technological miracles of his superiors. After all, who wouldn't want the power to read thoughts, dodge bullets, and remotely Connect to any mind on the planet?

When he gains these abilities, he uses them as any teenager would: he wreaks havoc. He flees from the consequences and begins a lonely and dangerous life in the city, protected only by the powers of a dead man's brain implant. Addiction and depression make him an easy target for those envious of his abilities.

A band of strange companions is drawn to him, each made an outcast by their own bizarre desires and fantasies. Their differences are an explosive mix, only partially restrained by their growing intimacy. As they draw closer, Cade's abilities become more unpredictable and dangerous. He will need to tap their deepest secrets as an unfolding conspiracy is turning friends to enemies, and enemies into something horrific.
