Case Study — FinTrack
A proof-of-concept accounting system built to validate systems-thinking capability: Telegram-bot input for non-technical operators, a constraint-first architecture, and a real production deployment.

Constraint-first, not theoretical
When designing systems — automation or software — I start from real operator reality: what can this person actually do, what constraints exist, and what can be standardized. That's the bridge between four months of manufacturing-floor fieldwork and FinTrack's architecture.
