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!

My Software Development Work
I've been building software for about as long as I have been talking; for big multinationals, small companies, and individuals. Whether it's setting up a company's architecture, or jumping in to provide extra development muscle at short notice, I've seen and done it all in the last 15 years. I also enjoy helping non-technical people to realise their dreams, whatever their field of expertise is. So please email me if you have any software-related questions.

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 technological advancement, 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 multimedia performance, to backend development. I've built services 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.

A few of my favourite things
These are some of the technologies which I enjoy using the most, or have been using recently. I can do others; just ask.

Current Projects

Own Apps

These are my self-published apps. These are mostly rapidly developed to fulfil some personal need, or just for fun.

iOS App Store
Android Play Store

  • 600 000+ downloads
  • Hands-free Browser app App Store rankings:
    • Overall top 5 in 8 countries for iPhone.
    • Utilities top 10 in 29 countries, in key markets: #2 iPad and #5 iPhone in France, #8 China, top 20 in Germany, Belgium, South Africa, India, Finland, Israel, South Korea.

Emerging Technology Consultancy ("Industry 4.0": e-Health, sustainable business, and IoT)

One of the grounds for optimism in these turbulent times, is the coalescing of various technologies into the basis of a new, more sustainable, economy. This will be a huge growth area in the forseeable future; I'm recommending all my customers to become acquainted with this field.

Interconnected, powerful, inexpensive, wireless devices have the potential to reduce environmental costs, and manage smarter distribution of resources, on a massive scale.

There has been an even greater parallel explosion in the potential of personal devices for healthcare, but these possibilities have barely been explored. I'm consulting with companies in the healthcare industry, to use emerging technologies to improve everyone's health.

Nocturnal Entertainment

Nocturnal Entertainment. Co-founder and Director. We released a crowdsourced Game Boy Advance game and an online, real-time collaborative development system. We tried this way back in 2002, before Google Docs, GitHub, or Kickstarter. We also made a space gardening game for Wii and Wii U: Flowerworks.
Multimedia Production
I've worked with media artists for the last 15 years, including: Mari Velonaki, Kate Richards, Anne Roquigny, and Martine Neddam. In Berlin, I mostly work with wearable touchscreens, using LEDs.

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

Wearable Tech

I develop bespoke fashion technology for fashion and performance productions. I have worked with Telekom Fashion Fusion, Marina Hoermanseder, and R. O. T. Records. I want to advance the aesthetic use of display technology beyond kitsch: From Christmas Tree Lights to Contemporary Art - the Aesthetics of Wearable LEDs - regarding moving beyond kitsch with wearable lighting technology.

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.
More details here.


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.
