About Me


Automation Authority

I am Zohaib Jahan — a TÜV Certified Functional Safety Engineer and DCS specialist with 11+ years of hands-on experience across the complete project lifecycle: Engineering, Commissioning, Startup, and O&M — for Worley on international Oil & Gas and Mining projects.

My technical scope spans Emerson DeltaV, ABB 800xA, Yokogawa Centum VP and Siemens PCS7. I apply IEC 61511 for functional Safety, IEC 62682 for alarm management programs, ISA 101 for high-performance HMI design, and IEC 61131-3 for DCS/PLC programming.

With 37,000+ LinkedIn followers in the I&C community, I am passionate about sharing practical knowledge — making complex standards like IEC 61511 and IEC 62682 accessible for automation engineers globally. Open to Pharma and Life Sciences projects in future.
