At Octopus Cards Limited (Appnovation Secondment), I delivered native Swift features for the Octopus app, aligning architecture, logic, and UX with the Android team. I also integrated iAM Smart OAuth 2.0 and designed a web-to-native setup for React JS components.
At Hang Seng Bank (GreenTomato Secondment), I created an iOS proof of concept in SwiftUI and resolved concurrency issues in cloud-deployed workflows. I implemented unit testing to 85% code coverage and delivered three major releases with the Android team.
Outside client work, I designed and operate a multi-agent AI automation system with provider failover and OAuth token lifecycle management. I also built a Python wrapper for ComfyUI workflows, with scheduled runs, output checks, and a cloud fallback.
