Testimonials

Jag has worked on a number of contracts for Cambridge University Press over the years.

Most recently I hired him to lead on a greenfield development for our Higher Education website. As the technical lead for this project Jag formed an excellent working relationship with the product owner and quickly grasped the business context of the challenge. Using his extensive technical skills and experience he architected a solution and then subsequently went on to build out both front and backend applications. He wasn't just code focussed, he remained involved in all aspects of the product development including UX, the Agile approaches & process being utilised, and continuous deployment with Kubernetes. As we grew a team around Jag he on-boarded and mentored new team members and ensured appropriate best practices were in place throughout their work.

Jag is highly committed and passionate about his work and is also a great team player, working well with both technical and non-technical colleagues.

I am very happy to recommend Jag for work in future companies.

Scott Merrick LLP
I hired Jag on a contract basis to assist the in-house development team, with delivering a product in the AngularJS framework. Jag brought with him invaluable technical experience and a great attitude to the agile development process of the project. Being one of the first developers to start work on the project, Jag was pivotal in the important early foundation work and quickly estabilshed himself as a well respected member of the team. This meant that the in-house team and other contractors would often turn to Jag for his opinion and advice on approach and best practice. Jag also actively suggested ways of improvement throughout the project, as well writing examples of and training the team on testing for AngularJS. During his time with us, Jag actively contributed to AngularJS modules, services, controllers, custom filters, custom directives, OO javascript, Karma & Jasmine testing, Documentation, Bower setup, LESS & HTML templates. Jag clearly enjoys the work that he does, is self-motivated and is an invaluable asset to any team/project.

I hope to have the pleasure of working with Jag again in the future.

During my time working as a Senior DBA at Cambridge Assessment, I worked extensively for many years with Jag in his role as Senior Developer. Throughout my time working with him, he was an approachable and effective communicator, talented consultant, and reliable colleague. His work not only met our expectations but he excelled them. He consistently reflected solid development principles throughout and was a vocal and effective advocate for best practices and for getting this shipped. Jag not only ensured that he was thorough in his understanding and practice of core development techniques and best practices but also took a strong interest in staying ahead of the curve with new and emerging technologies. His approach ensured quality delivery and deployment of code and was a valued member across all teams in the organisation who required his skills and insights. I believe Jag will be an asset to any organisation he joins and will be able to flourish anywhere given his skills, adaptability and clear ambition to learn and succeed.

I look forward in working alongside Jag once more in the future should that situation ever arise.
