- Client
- PT Deva Indonesia Group
- Year
- 2021-2026
- Sector
- Industrial

Visitor management software for industrial sites, later reworked with a full PRD, system architecture and sprint plan.
Context
Industrial sites need to know exactly who is on the premises, when, and why, for safety, security and compliance.
The challenge
Visitor logging was manual and inconsistent, making it hard to track access or produce reliable records.
- Manual, error-prone visitor logs
- No real-time view of who's on site
- Compliance and security gaps
My role
- Founder
- Product lead
- PRD & architecture
- Sprint planning
Approach
How it came together.
- 01
Started as a focused tool, then re-grounded it in a full PRD and architecture as it matured.
- 02
Designed for the realities of an industrial site, not an office.
What changed
- A working visitor management system for industrial clients
- A clean PRD and architecture for future iterations
Rewriting the spec for a product that already exists is humbling, and the fastest way to see what you got wrong the first time.
