IP, tech, other interests
Welcome to my website. I’m a lawyer and minor softare developer, among other things, living in London UK. I mainly use it to write personal notes about topics connected to intellectual property, law, and technology and other things I find interesting (for example knitting).
I also publish and maintain BunTool, a free and open-source tool (without tracking, cookies, or any kind of data harvesting) for people to organise their papers for court and other legal settings. BunTool is a used by unrepresented people, charities, solicitors, barristers, mediators and some judges.
You can also find me on GitHub, LinkedIn, or email me. This is entirely a personal page and unconnected to my work as a partner in Bird & Bird’s IP team. If you’re interested in my professional work or looking for legal advice you won’t find it here — please go to Bird & Bird.
