Why I Started TechDoor
I started by just figuring stuff out. Taking apart old computers, fixing friends' and family's laptops for next to nothing, reading everything I could get my hands on about how networks and security actually work under the hood.
That curiosity eventually turned into something more serious. I trained as a SOC (Security Operations Centre) analyst — the people who sit in the background monitoring networks for threats and responding when things go wrong. I've seen the inside of real cyber incidents. I understand how attackers think, what they're looking for, and — crucially — how straightforward it is to stop them when you've got the right setup.
So I started TechDoor. The idea is simple: bring proper, qualified tech support and cybersecurity to the people who actually need it — at their door, with no jargon, at a fair price. Your nan deserves the same quality of help as a FTSE 100 company. She just needs it explained differently.
That's what I do. Come on in.
Why Choose TechDoor?
There are plenty of tech people out there. Here's what makes working with Jack different.
Genuinely Local
Based in Cardiff. Jack knows the area, comes to you, and isn't farming your job out to anyone else.
Fully Insured
Professional indemnity and public liability insurance — proper business, proper protection for you and Jack both.
No Jargon. Ever.
Jack will never talk to you in jargon. If he can't explain it simply, he hasn't understood it well enough himself.
No Call Centres
You call, Jack answers. You message, Jack replies. Same person, start to finish — no tickets, no queues, no hold music.
A Real Person — Not a Bot
There's no AI chatbot pretending to help here. Just a human being who actually knows what they're doing and cares about getting it right.
Cybersecurity Trained
Not just a repair shop. SOC analyst background and BSides speaker — so you get that expertise built into every job, not just the security ones.
Three Things Jack Actually Believes In
Honest
No hidden fees. No upselling things you don't need. If your laptop isn't worth repairing, Jack will tell you — even if that means he doesn't get the job. Long-term trust beats a one-off invoice every time.
Human
Real conversations. Real help. Jack remembers he's in your home, with your stuff, talking to a real person — not processing a support ticket. He'll have a cup of tea if you offer.
Helpful
Jack doesn't leave until it's fixed and you understand what happened. And if something comes up after he's gone — drop him a message. He doesn't disappear the moment he's been paid.
