Amr Ibrahim
Senior HVAC & Mechanical Engineer • MSc • PhD Researcher
Twenty years across oil & gas facilities, pharmaceutical cleanrooms, industrial HVAC, and heavy process plants — from initial design through installation, commissioning, and field diagnostics. If it moves air, controls temperature, controls humidity, or maintains pressure — I have built it, fixed it, and designed it from scratch.

How I Can Help
Three Ways, I Can Help You
Whether you need a senior engineer on your team, expert consultancy for a specific project, or professional training for your engineering department — this is what I do.
Hire a Senior Engineer
I am open to the right senior or leadership-level role — in pharmaceutical manufacturing, oil & gas, or heavy industrial engineering. 20+ years of field experience, GMP compliance knowledge, and a track record delivering on large, complex projects across MENA and East Africa.
HVAC Consultation, Design & Site Visits
Facing a system that's underperforming, a facility that failed a GMP audit, or a new project that needs to be done right the first time? Specialist HVAC and mechanical engineering consultancy — from cleanroom pressure cascade design to field diagnostics.
Professional HVAC Training
Structured technical training for engineering teams and individual professionals — covering GMP-compliant facility design, HVAC fundamentals, cleanroom system operation, and industrial troubleshooting. Built from 20 years of field reality, not textbooks.
The Difference Between a Pretty Layout and a Compliant One
Most design firms produce impressive 3D renders. An experienced pharmaceutical engineer spots the GMP violations in minutes. Below is a real layout submitted as GMP-compliant — it contains five critical audit failures that were never flagged before review.
Fatal Pressure Cascade
Class D at 60 Pa adjacent to Class C at 50 Pa — pushes contamination backward into the cleaner zone.
Missing Airlock (PAL/MAL)
Direct personnel flow from Class C corridor into Class B sterile core with no gowning step-up.
Gowning Violations
Class B sterile garments shown in lower-grade Class D areas — destroys sterile integrity.
Incomplete Washing Room
Should be divided into Dirty, Washing, Drying, and Clean zones. Shown as one undivided space.
Corridor Classification
Main clean corridor must be Class D with secondary change rooms for Class C access.
