Full-stack / Platform Engineer
Louis Wen
I design, build, and operate automation-heavy systems across hotel platforms, internal tools, IoT, and infrastructure workflows. My strength is turning repetitive, fragile business operations into reliable software systems — from backend architecture and cloud infrastructure to team rollout and production maintenance.
