IT Strategy & Governance
I set the technology roadmap against the business strategy, the growth plan and what operations can actually absorb.
I own the IT budget, procurement and lifecycle planning, and I negotiate the vendor contracts behind them.
Driving innovation and transformation across logistics, healthcare, defence and education.
Fifteen years building and running secure, cloud-first platforms for government and regulated enterprise clients.
Based in Singapore. Available by email.
Who am I
Christopher Cai
蔡亦展
Co-founder and CTO, Intrasys
I co-founded Intrasys in 2011 and have led every technology function since — infrastructure, applications, cybersecurity and operations.
I set the technology strategy and stay accountable for what it delivers — the cloud foundations, the security baseline, the applications on top and the firmware in the field. I own the budget and the vendor contracts behind all of it, and I do this for Singapore Government agencies in healthcare and defence, and for regulated enterprise clients, where uptime and data sovereignty are not negotiable.
I spend as much time translating technical roadmaps for non-technical stakeholders as I do building the teams that deliver them.
What I own
Cloud & Infrastructure
On-premises and cloud, network, endpoint and AV — for our own operations and for what we deploy to clients.
Azure governance across 10 subscriptions, AWS platform architecture, and operations standardised on ITIL-aligned practice.
Cybersecurity & Data Protection
Data sovereignty is the first constraint on a design, not a review step at the end of one.
The secure device baseline is mine: Azure AD join, MDM enrolment, USB blocking, encryption and patch compliance.
Selected work
Prism
RFID readers and cameras produce signals that never reach the people running the floor.
A sensor-fusion platform that streams those signals into visual workflows, so an operation can be watched as it happens rather than reconstructed afterwards.
prism.intrasys.aiPresto
A web app cannot reach a label or RFID printer without a driver and a print dialog in the way.
A print fabric: one small native service that prints from the browser to label and RFID printers over a secure local connection, with neither.
presto.intrasys.aiPulse
Nobody can say who is around today or what the team is actually working on right now.
Ordered per-person priorities, live presence and one real-time dashboard, on web and mobile, with share links for an office screen and no login.
pulse.intrasys.aiJapan Post Warehouse Control System
Every stock movement is reconciled against the system of record, so equipment, inventory and host never drift out of agreement.
Real-time control layer between the warehouse floor and the host WMS, binding Mitsubishi PLCs, SICK machine vision and conveyor motor to Toshiba WMS over a strict-timing MQTT backplane.
10 / 10 strokes
AI Strokes
A research-to-classroom AI/ML project for Chinese-language stroke-writing instruction, aligned to the Singapore MOE primary-school syllabus.
I led delivery of an iPad application for students and a real-time companion web app for teachers in React.js, streaming each student's stroke-by-stroke writing live for in-classroom observation.
I integrated an ML scoring model assessing stroke count, individual stroke formation and stroke positioning, with exportable results for offline teacher review.
I engineered the platform on AWS — Beanstalk, IoT and Cognito — to support 40 concurrent students per session. It was piloted at Northshore Primary School in 2022.
