But Taiwan's largest EV network offered the opposite

🚀 THE RESULT
I redesigned the entire charging journey — from parking to full charge
Animation and haptics turn confusing steps into guided experience for drivers
World's 1st reservation solution guarantees available chargers for people in need
World's 1st App Clips in EV charging let new users charge instantly without complex signup
🧃 Impact
My design leadership delivered measurable turnaround for the product
Daily user complaints reduced
Charging failure rate reduced
App rating transformation
"Eric's passion, endurance, and flexibility make him a one-of-a-kind designer and project manager who delivered impactful results."

Key Learnings
Innovation doesn't mean the most advanced technology
My ideal hardware for reservation system exceeded the budget. But finding middle ground — semi-automated parking locks — still enabled the world's first EV charging reservation system without massive capital investment.
Technical constraints can unlock better solutions than perfect freedom
Instead of hiding EVALUE's counter-intuitive charging sequence, I transformed it into a guided experience using animation and haptics. The limitation became an opportunity for clear, deliberate user guidance that competitors lacked.
