I steer the design, optimisation and start-up of major refinery units, turning process models into safe, reliable capacity. Leading a multi-disciplinary team, I convert early concepts into fully documented, operable plants. • Process simulation – Build rigorous CDU/VDU, NHT, DHT and Catalytic Reforming models using Aspen HYSYS/Plus, Aspen EDR and AFT Fathom; identify debottlenecking and >5 % energy-cut opportunities. • Engineering deliverables – Author PFDs, P&IDs and HMBs that anchor HAZOP reviews and drive flawless construction. • Energy integration & optimisation – Conduct pinch and heat-recovery studies. • Safety leadership – Facilitate HAZOP, LOPA and SIL workshops; embed API, ASME and IEC 61511 requirements from first sketch to hand-over. • Commissioning & start-up – Direct system checks, catalyst loading, line-up and performance tests; achieved first-oil KPI hits within 72 h on three units. • EPC & vendor interface – Single process focal for licensors, contractors and suppliers; resolve technical deviations, accelerate long-lead items and keep the critical path clear. My approach blends analytical rigour with frontline problem-solving, ensuring every project returns sustainable value—safer, cleaner and more profitable.

Senior Process Engineer

Jul 2023 - Jun 2024 • 11 mos

Passionate about turning complex processing challenges into streamlined, high-performing solutions. I lead the full lifecycle of oil-and-gas process design—from concept development through detailed engineering and continuous improvement—focused on: Efficiency & Profitability: Creating layouts and heat-integration schemes that cut energy use, reduce bottlenecks, and boost throughput. Safety & Compliance: Embedding HAZOP, SIL, and industry standards into every design to protect people, assets, and the environment. Sustainability: Integrating flare-reduction, waste-heat recovery, and low-emission technologies to meet ESG targets. Data-Driven Problem Solving: Blending rigorous simulation (Aspen HYSYS, Pipesim, CFD) with hands-on troubleshooting to deliver actionable, plant-ready solutions. Cross-Functional Leadership: Aligning operations, maintenance, and project teams to accelerate commissioning and hit performance guarantees on day one. I thrive on translating analytical insight into practical designs that keep facilities running safer, cleaner, and more profitably.

Process Engineer
