Thanks for visiting Sullen Art. For more than 25 years I’ve run companies providing a whole range of software development services, particularly to the mobile data industry. I can offer everything from client-facing requirements gathering, design and development to documentation and installation. I have personal expertise in Kotlin, Java and C/C++ for embedded and Android development, and Kotlin, Java and node.js for back-end cloud hosting services. But I can also just as happily lead a development team, locally or remotely. You can see see my CV or you can contact me with any questions. While you’re here have a look through the blog posts for a whole range of topics – computing, electronics, woodwork and anything else that takes my fancy.
