Working With Us

The Team

In this section

Founded in 1991, we have provided business and management consultancy services to government, academic and commercial organisations in the UK and internationally across a range of industrial sectors, but highly focused on farming, food and the environment.

The company's employees are predominantly science and engineering graduates and researchers. They are complemented by equally qualified and experienced administrative and commercial staff.

Our management team have decades of experience designing, developing and supporting our clients and improving the underlying technology that makes this possible.

Les O'Leary - Managing Director

Les has spent his career in the solid state electronics and information technology sectors with a special interest in systems design. A veteran of when an MSc, festivals and thought were free, Les enjoys working at everysite because 45 years after his first attempt at programming a computer, he does want to know if business too will always be NP-complete.

Sasha Rebmann - Creative Director

Sasha has been involved with everysite since its inception in 2002, and enjoys the freedom of working on anything from our strategic direction to tweaking high-performance code and making sure everything is coloured purple to bringing cutting-edge technology to the food and farming sector. Away from the computer he likes to get into the hills on his bike and still buys music on vinyl.

Amy O'Leary - Operations Director

Amy was involved in setting up everysite back in 2002.  Officially responsible for company operations, she can be found turning her hand to everything from delivering large government projects to making the tea. Amy enjoys working at everysite because of the value placed on the intelligence and creativity of all members of the team. Outside of work she has two cheeky kids to keep her busy and enjoys sewing when she gets time.

Dr Christopher Wise - Business Development Director

Chris worked in crop production for almost 30 years and was a founding father of Assured Produce, the fore-runner to the Red Tractor scheme. After a spell in construction, he is enjoying his return to agriculture and working with everysite. In his spare time he can be found wrestling in his barn with two old Reliant sports cars or getting in a pickle in his equally ancient sailing dinghy!

Arthur Burrows - Technical Manager

Arthur has been tinkering with computers for over half his lifetime, a profession in making them do his bidding was only natural! If he's not in the great outdoors or away exploring the world, he loves to make his own beer. Arthur takes great joy in seeing innovative systems become a reality at the hands of the talented everysite team.

Maïté Buns - Services Manager

Maïté spent her 20s working in the customer care industry for global companies before joining the friendly everysite team in their pursuit of better IT solutions. She is proud to work with fun, smart and badge-less people and enjoys learning something new every day. Away from the phone and her computer, she is a jewellery designer, a baker and a vintage sales rummager.

Afshan Jaffrey - Engineering Manager

Afshan has been working in the IT and software industry for over 10 years and specialises in Web Systems Development. She enjoys being a part of the everysite team because she gets to work with a talented group of people doing brilliant things and who are just as addicted to tea as she is.

John Jairo Palma Robayo - Engineering Manager

John has been working in the software industry for more than 9 years where he has been involved in projects ranging from business intelligence applications to back-end and web development. As part of everysite, he's happy to learn new stuff every day as a member of a busy team. On his spare time he writes (and listens to and reads about) music, plays (and reads about) games (and reads, when riding his bike is out of the question).


Stephina Pascho - Software Engineer

Stephina joined Everysite right out of university. She has enjoyed spending her workday learning more about software development and data. In her spare time, she enjoys binge reading fantasy novels, going on walks around town, and developing video games.
