Mehdi Omidi Nobijari

As a Process Engineering Specialist with more than 13 years of experience in oil, gas, and water EPCM projects, I have contributed to all stages of engineering—from conceptual design and PDP through FEED, detailed design, and commissioning. My expertise includes process simulation, design optimization, equipment sizing, and hydraulic analysis. Combining this with hands-on experience in fabrication and field technical support enables me to deliver practical, client-centered solutions and maintain strong collaborative relationships.
