Kam Yen Cheah is a software developer and project manager with 30+ years of hands-on experience building production systems on Windows and Linux. He has led full-stack projects in Python, .NET/C#, and SQL, designed company-wide applications, and coached teams on writing dependable, maintainable code. Kam’s specialty is turning one-off scripts into reliable services: scheduled jobs, safe database updates, logging/monitoring, and troubleshooting under real-world constraints. He teaches with a practical, step-by-step style—showing not just how to make something work, but how to keep it working unattended. When he’s not building tools, he mentors younger engineers on fundamentals, disciplined debugging, and professional practices.
