Digital mall kiosk — Tech Lead
I led development of an AI customer kiosk now live in multiple malls, with a national rollout planned for 162 locations.
For a major Japanese shopping-mall operator, I led a digital kiosk that helps shoppers find stores and services, and call a human operator by voice when they need help.
What I contributed
I elicited requirements, designed the solution, ran the project, and led development — coding myself while directing three engineers. I ran weekly meetings with the client in Japanese, stayed on call for support, and owned uptime, security, versioning, and rollout.
Stack
Python backend, Kotlin Android app on the tablet, React admin panel, AWS (EC2, Route53), WebRTC voice calling, LLM/voice APIs, PostgreSQL.
Outcome
The AI customer kiosk is now live in about five locations, with a national rollout planned for 162 locations across Japan.
