About
Nguyễn Hải Đăng
Operations Digital Transformation Advisor
I digitalize factory operations — study how a line actually runs, then turn what lives on paper and in operators' heads into usable data. Over seven years I moved from the equipment side (SCADA, EMS, BMS, MES) to the software side, and now build the systems I used to only advise on.
What I do
Operations assessment & advisory
On-site assessment, mapping the real work and data flows, identifying where data breaks before discussing any software.
Industrial monitoring systems
Design and deployment of SCADA, EMS, BMS and MES for substations and plants — the IT/OT layer where equipment data reaches management.
Building operations software
Writing and operating CMMS and OEE systems — not reselling a vendor package, so the odd requirements of each site can actually be handled.
Credentials & education
Formal training behind the GxP content on this site. Verifiable on my LinkedIn profile.

Systems running in production
Most digital transformation consulting stops at the proposal. The difference here is something you can open in a browser: the systems below are running in production, used daily.
Industries I write in depth about
Each industry has its own operating standards, so the content follows those standards rather than staying generic.
Where to start reading
Each track starts with the industry standard, then moves to measurement and daily operation. Reading in order avoids missing context.

Why the content here is trustworthy
Everything published here is written from systems I build and operate myself. Below is what that means in practice — each point can be checked against the site itself.
- Written from systems in production
- The articles come from software running in real factories every day, not from vendor brochures. The links above open the live systems.
- Limits stated in every article
- Each piece ends with a transparency note naming what it does not cover and which parts you should verify against the original standard before applying.
- Cited to primary standards
- References point to source documents — EudraLex, ISPE GAMP 5, ISO 22400-2, SEMI, FSSC 22000, IATA — rather than to opinion blogs or reposted summaries.
- Corrected when standards change
- Clause numbers and standard versions shift over time. When a cited version is superseded, the article is updated rather than left as it was.
If you are weighing up digitalizing a specific operational area, describing the situation is enough to start.
