Trading Automation for an In-Game Marketplace
Automation for a constrained external marketplace with strategy logic, execution control, and logging.
End-to-end
Strategy layer
Constrained external platform
Operational loop
Trade execution goes through service logic, not brittle UI automation.
The point is controlled execution, logging, and strategy, not automation tricks.

Problem
The platform was unstable enough that naive scripts failed quickly.
Solution
Designed the API layer, strategy controls, and execution loop from scratch, based on reverse engineering and the platform's actual behavior.
Impact
The system could keep running under platform changes instead of falling apart.
What I built
- Designed API interaction, execution control, and logging as one operational loop.
- Adapted automation behavior to real platform constraints instead of ideal assumptions.
- Kept the system supportable under frequent external changes.
What this proved
- Good automation starts with a stable service layer, not with UI macros.
- Reverse engineering is only useful when it becomes a maintainable interface.
