Problem
Vehicle entrance weighing needs reliable software integration with scales, barriers, and alarm hardware in industrial environments.
Solution
Field integration: serial communication for weight reading, overload threshold detection, barrier/signal hardware interlocks. Documented interfaces for maintainability.
Key Highlights
- ▸Field workflow: vehicle on scale → software reads weight → triggers alarms → coordinates barrier interlocks
- ▸Advocated for team-aligned stack over individual familiarity
- ▸Documented interfaces and operational risks for next maintainer
- ▸Professional execution under non-preferred stack decision

What I Learned
Technical disagreements should focus on maintainability and bus factor; when the org picks a lane you don't own, execution quality and written-down risk beat hallway debate.
