Senior Consultant

I have worked with Cartesian over the past 14 years, firstly as a customer receiving excellent quality people to help deliver my projects and then as an associate myself and now most recently converting to an employee, as a Senior Consultant. The projects I have worked on have been large complex projects and all part of a larger programme of work. These have significant impact to the UK public and carry great importance with each deliverable. Most enjoyably, I get to work with an excellent team of professionals who get the job done.

The time I spend interacting with my colleagues to solve problems for our client, is my favourite part of the day.

The new office location is near a vibrant street food market so it is possible to eat excellent food, reasonably priced, from all over the world on our doorstep. In one week you can cover multiple Asian food styles (i.e. Korean, Japanese or Chinese) and South American styles (i.e. Brazilian & Argentinian) along with traditional BBQ food, British Roasts or Spanish Paella and much, much more…

The Cartesian culture is an ethical one, aimed at delivering value for our clients, whilst we grow the business. Through all of this we have a supportive team and we aim to have fun along the way.
