Client's Recommendation

Jia Li, Development Manager, Kurt Geiger - London, UK

“Karthikeyan has worked as a front-end engineer in my team in the last few months. He has excellent react skills and helped us to deliver a couple of projects. I found him to be hard working, has a good attitude and communication skills. I look forward to working with him again in the future and highly recommend him for any role.”

Robin Fairless, Technical Director, Blok Solutions - London, UK

“I have been exceedingly fortunate to work with Karthikeyan on a daily basis, for the last ten months.

He is a gifted engineer with fabulous back-end development and DevOps skills. He was a key member of a team that managed to salvage a failing project and create something special.

Even when confronted with tasks outside of his existing knowledge base he knuckled down and mastered new skills and knowledge quickly and with enthusiasm.

Karthikeyan brought a happy, jovial but professional attitude to every interaction, even when there was a severe issue with the project. He never let the issues defeat him and always overcame them.

I can safely say that I would work with Karthikeyan on any project, and I cannot recommend him enough.”
