I've spent my career on the technical side of customer support. I help customers at every stage, from onboarding and best practices to fixing hard production issues, and I mentor engineers and manage escalations along the way. What I enjoy most is taking a complicated problem and turning it into clear steps a customer can act on.

He has been extremely cooperative and a great mentor from the first day I joined his team. He is excellent at taking critical actions and making good decisions for our team on a daily basis, while his working ethics and IT skills make him a great asset to our company.

Hiring for a support engineering or team lead role? I'd love to hear about it. Email me, message me on LinkedIn, or grab my CV below.
I'm Irish, living in Ireland, and I like to stay active. Most days you'll find me doing calisthenics or lifting weights, which keeps me disciplined.
On weekends I go hiking around Ireland with my camera and photograph the landscapes along the way. I'm also into DIY. Fixing or building something with my own hands is really satisfying.
I love to travel, see new places and get to know different cultures.
I also make content online. You'll find all of it at shah91n.pages.dev.
