What I'm looking for

I'm open to customer support, technical support, QA, and project coordination roles.

I built a system that runs the business of 20+ rental apartments, handling guest requests and coordinating cleaning and maintenance. AI answers standard questions within 1 to 5 minutes, and the client communication rating has stayed at 4.9.

At a trucking dispatch CRM and driver app company, I tested the iOS app and web CRM, wrote test cases and bug reports, and triaged requests and bugs. I also built CRM features and REST APIs, and coordinated client requests and releases with a 7-person team.
