Banknote Paper Mill Integration
Chunxiao Technology · 2018 – 2020
Role: Developer & Integrator
Cover
High-secrecy banknote paper mill on-site integration. Air-gapped environment with no internet access — offline laptops for data format analysis, in-plant testing, and external development cycles. Each site visit required ~1 week advance approval.
Delivered integration under strict secrecy, managed air-gapped deployment with controlled release artifacts
Problem
High-security banknote paper mill prohibits internet access on-site, making traditional development and deployment impossible.
Solution
Air-gapped workflow: offline laptops for format analysis and in-plant testing, external development cycles, controlled transfer paths for deployment. Small provable checkpoints per visit with transparent scheduling communication.
Key Highlights
- ▸Delivered under strict secrecy with no on-site internet
- ▸Formal access controls: ~1 week lead time per site visit
- ▸Air-gapped deployment with offline artifacts and rollback discipline
- ▸Aligned expectations via provable checkpoints per visit
Tech Stack
What I Learned
Air-gapped environments require extreme off-site preparation; expectation management is critical when access friction causes non-visible progress days; controlled deployment paths need extra packaging and verification.
