ISMS Station Management.
One system for a whole service station, across every branch.
A service station runs fuel, LPG, a car wash, a shop, a pharmacy and payroll on separate tools, and the owner can't see the whole business in one place.
Every part of the station in one place.
A multi-tenant station ERP: fuel and LPG, water production, automotive, car wash, POS for the mart, pharmacy, restaurant and bakery, Kenyan payroll, CRM and finance, plus a Flutter mobile app.
Choices that made it hold up.
Refresh-token rotation with reuse detection
A stolen refresh token is detected the moment it's used twice, and the session is killed.Why: station staff share devices
Alert on new IP addresses
Sign-ins from a new network are flagged to the owner.Why: early warning of misuse
Station-scoped access
Every role is limited to its own station and modules.Why: one owner, many branches
Production launch after UAT on the AWS staging environment.
