Gui is an extremely talented, quick-thinking and experienced engineer. He always was eager to help with any technical problems I had on the marketing team at FundApps, and he is a fantastic teacher.

I greatly enjoyed working with Gui and the quality of his work was outstanding. Gui helped me fix critical problems with our corporate website and CRM, as well as wrote custom code to expand our functionality in HubSpot.

I'll always be grateful for the time Gui spent teaching me HTML and CSS concepts and best practise, and I'm a much more accomplished marketer thanks to the mentoring he gave me while I was at FundApps.

Guilherme Zühlke O'Connor is a passionated Front end Developer and architect located in London, UK

With as much passion for graphic work with colors, typography and layout as he has for coding, science and technology, he has been working on the web since 1997 for small and big projects as a free lance as well as a staff member of respected companies and has taken part on the development of awarded sites and has been awarded for innovation in science and technology for work on the web.

Naturally a generalist, I am a versatile problem solver, result of a lifelong passion for learning and discovery I carry with me a wide range of skills tuned over two decades of professional web and software development and academically by studying Architecture and Computer science.

The core of my experience is on web development —an interest that flourished in the late nineties when, having taken a visual design tangent on my architecture course, I connected to the programming skills I had developed earlier— which eventually led me to work in web giants like Yahoo and exciting and fresh startups like Snupps.

My experience, however, over the course of my career has been as diverse as working with the development of prototype mobile phones for Sony Ericsson in the period of fast change just before the emergence of smartphones, photographing theatre for The Old Vic, Lecturing compiler design on a University or organizing and lecturing courses on a variety of areas of knowledge.

The common ground between all those seemingly unrelated areas is a systematic, down to earth approach to innovation and problem solving, as well as the passion to create beauty on it's different forms, from the graphical appeal of photography to the conceptual beauty of mathematical formulae.
