- Moved HCM & HN FCs off Google Sheets by driving system-based inventory adoption (stock ~98% accurate with continuous updates).
- Shipped a hybrid stock-counting flow (paper + app) to fit flexible warehouse workflows and cut time spent on discrepancy investigations.
- Rolled out app-based picking to reduce manual entry, improve productivity tracking, and keep fulfilment status up to date.

- Worked with risk/ops to implement auto-verification logic, cutting verification time to ~1 hour.
- Designed the internal ops console (onboarding, transactions, disputes, settlements) with role-based workflows.

Design Principle
USER -CENTRICITY
Pain first. Features later
Great design starts where users struggle. Friction, workarounds, and “small complaints” become the real spec. Once the pain is clear, design objectives write themselves.
USABLE BEFORE PERFECT
Make it happen first, perfect later
A clean v1 beats a perfect concept. The fastest way to learn is to ship the simplest path that works, then iterate with real cases instead of hypothetical debates.
ARCHITECT BEHAVIOR
Design the behavior, not the interface
The best products make the right action feel like the natural one. Clear defaults, deliberate sequencing, and guardrails reduce training, reminders, and manual policing.
