ZJNSBF Ltd is a Belfast-based technology and business solutions company, operating from Unit 8 at Blackstaff Mill on Springfield Road — one of Belfast's established business hubs.
We work with organisations of all sizes, delivering practical, effective technology solutions that are built around real business needs — not off-the-shelf packages that sort-of fit.
We follow a clear, four-stage process: understand your needs, plan a precise solution, build it properly, and then support you long after go-live. Every engagement is structured around outcomes, not activities.
No unnecessary complexity. No scope creep. Just well-engineered technology, delivered on time and within budget — backed by a team that actually picks up the phone.
Longhe Zhu founded ZJNSBF Ltd with a vision to bring sharp, results-focused technology services to businesses operating from Northern Ireland — combining deep technical expertise with a commitment to outstanding client service.
Based in Belfast at Blackstaff Mill, Longhe brings an international perspective and a hands-on technical background to every project. He works directly with clients to ensure that solutions are not just well-built, but genuinely aligned with their business objectives.
"Technology should make business simpler, faster and more competitive — not more complicated. That is what we set out to deliver, every single time." — Longhe Zhu.
We are small enough to care deeply about every client, and experienced enough to solve problems at scale. That combination is rare — and it is exactly why our clients stay with us.
You speak directly to the people solving your problems — no sales layers, no handoffs. Faster decisions, better outcomes.
We guarantee a response to all support and enquiry requests within 24 hours — and usually far faster.
No hidden costs, no scope creep and no surprises on invoice day. You know what you are paying before we start.
We bring genuine engineering expertise — not just project management. We understand what we are building, end to end.
We are local. Based in Belfast's Blackstaff Mill, we can be on-site when it matters and we understand the local market.
We build solutions that grow with your business — not ones you will outgrow in 18 months. Future-thinking is standard.
ZJNSBF resolved in a week what our previous IT supplier had been struggling with for months. Longhe came in, understood the problem quickly and delivered a clean, well-documented solution. Outstanding technical ability and professionalism.
We needed a bespoke system built fast and built right. ZJNSBF delivered exactly that — on time, within budget, and with full documentation and support. Their approach is methodical and the communication throughout was first class.
Switched our entire infrastructure to cloud with ZJNSBF handling the migration. Zero downtime, everything worked perfectly and they trained our team patiently on the new setup. We've saved significantly on IT costs since and the performance is far better.
