Thirty years of turning raw technology into working infrastructure.
Yen Choi is a technology and infrastructure strategist working across telecommunications, AI infrastructure, data centres, energy, and digital transformation. He focuses on the practical systems behind digital growth — connectivity, compute, power, cooling, data sovereignty, and commercially viable infrastructure delivery — with on the ground experience of over 2 decades across Africa, Asia, the Americas, and Europe.
Experience that mirrors technology development
Apple II, no floppy drive
Typing programs in by hand. Learning computing from first principles, when nothing was handed to you.
A BBS on a 1200 baud modem
Running his own online system years before the web existed — dial-up multi-user systems, message boards, file transfer. The pre-internet internet.
One of the first ISPs in Canada
Bringing 28.8Kbps dial-up internet to market when commercial internet access barely existed — turning a raw technology into a working business.
International calling, no computers required
A commercial discount calling platform built on custom VoIP over DSP boards connected to the PSTN, backhauled over international private leased circuits running IP — cheap international calls to ordinary phones, years before mass-market calling cards.
Pan-African broadband, built on the ground
Building the satellite broadband platforms, fixed-wireless networks, and enterprise fibre that carried connectivity across the continent — infrastructure that had to work in markets where nothing was handed to you.
Managed services and digital transformation
Running managed services and driving digital transformation — the bridge between raw infrastructure and what it actually delivers for people and business.
AI infrastructure, data centres, fintech, advisory
The same instinct applied to the current wave: identify the technology early, understand the physics and the economics, and make it commercially viable in markets others overlook.

How he thinks
Patterns across domains
As a member of Mensa International, it's all about pattern recognition — problems, solutions, and risks repeat across industries. Data-centre cooling logic applies to agriculture. Telecoms reliability practice applies to digital banking. Seeing the pattern is where the leverage is.
Making the complex clear
Infrastructure decisions are made by boards, investors, and policymakers — not just engineers. Moving fluently between the machine room and the boardroom is what turns technical judgement into real-world outcomes.
Commercial realism
Armed with an MBA in Finance and Accounting but sees beyond it. Technology that can't pay for itself doesn't scale. Every assessment starts with power availability, operating cost, financing, regulation, and demand — not the demo.
What he's known for
- Clear technical judgementTelecoms, networks, wireless, satellite, data centres, power, cooling, AI infrastructure.
- Commercial realismCosts, business models, financing, operations — what can actually work.
- Local context, anywherePower reliability, affordability, connectivity gaps, regulation, local capacity, data sovereignty — read on the ground, not from a report.
- Practical problem solvingNo vague future talk. No copied trends.
- Cross-sector thinkingTechnology × property, energy, finance, public policy, infrastructure delivery.
