John Grímsey

Freelance Angular and full stack JavaScript developer in London.


I've got four years full-time top ten agency experience and almost fifteen years of contracting under my belt. I've worked for agencies, start-ups and corporates.

I love to work in technical roles that allow for input on UX. I consider myself a both-sides-of-the-brain developer with an eye for design aesthetic and usability (without compromising on my coding).

I can be relied upon to be a client-facing techie. I am a highly organised developer with people skills. I understand the importance of communication and am passionate about helping team members and stakeholders to understand technical considerations. I enjoy solving deep problems and bringing order to chaos.

Senior Experience

I have plenty of experience in taking a project through from brief to execution.

Gathering requirements, wire-framing, planning for code that has to last and will scale. Developing myself and coordinating small teams of developers to deliver, both frontend and backend.

I work well with project managers and can be a highly effective go between for painful technical details and realistic planning. I have stood in for absent Technical Directors with major corporate clients in meetings.

I enjoy guiding junior developers, helping to strengthen both their problem-solving and coding skills.

Very much at home in an Agile environment. I've helped to refine Agile processes in some of the places I've worked.
