Timeless Ambition: Faith & Tech
I’m back after being away for a long time.
Exploring my journey in mainframes and faith through technology and LDS temple visits worldwide.
Timeless ambition 无限雄心
Tech Journey
Exploring the intersection of faith and technology in my life.
SAFE on DOS/VSE IBM 4361
My professional journey in enterprise IT began with the IBM 4361 system, running the DOS/VSE operating system. Started by writing programs in COBOL and Assembler on the SAFE system, DL/I and CICS, laying the foundation for my career as a mainframe system engineer.
VSE/SP for CARS, MERVA
Migrated to the VSE/SP system with CICS and DL/I, developed China’s first and revolutionary ATM network system (CARS), and maintained China’s SWIFT messaging system (MERVA).
MVS OS/390 for ABCS
Continued my mainframe journey on MVS and later migrated to OS/390, with extensive work on CICS and DB2. Successfully implemented Sysplex for code and warm backup/recovery to support the ABCS core banking system.
z/OS for zCITA

A Tribute to Dr. Gene Amdahl and the Legacy of IBM Mainframe
My deepest respect and gratitude go to Dr. Gene Amdahl, a founding father of IBM’s OS/360 and the visionary behind Amdahl Corporation. His pioneering work laid the foundation for modern enterprise computing and changed the direction of my life.
It was through the IBM Mainframe system—born from Dr. Amdahl’s vision—that I first touched the heart of system architecture. I began my career programming COBOL and Assembler on the IBM 4361 running DOS/VSE, and from there, my journey unfolded across generations of mainframe innovation: from DOS, VSE, MVS, OS/390 to z/OS, with CICS, DB2, IMS, and beyond.
But this journey was more than technical. Working with IBM Mainframe systems taught me discipline, logic, and structure. These qualities became the framework not only for my profession, but for my personal growth. Over time, this clarity helped open my heart to something greater than code—a spiritual awakening that led me to faith in Jesus Christ, and eventually to be part of The Church of Jesus Christ of Latter-day Saints.
Tambition—Timeless Ambition came from AMDAHL, reflects a vision that goes beyond technology.
