Reliable online HVAC & MEP freelancer highly responsive, client-focused, and committed to clear communication throughout every project. I’m a Senior Mechanical Engineer with 19+ years of experience in HVAC & MEP design for hospitals, commercial buildings, hotels, offices, and industrial facilities. I deliver clear, code-aligned design packages you can build from: load calculations (HAP), equipment selection, duct/pipe sizing, layouts, and coordinated AutoCAD drawings. What you get: • Heating & cooling load calculations (HAP) + summary reports • HVAC system design (ducted/VRF/mini-split) and equipment schedules • Ductwork/pipework layouts, risers, details, BOQ support • MEP coordination and clash-ready drafting (AutoCAD) If your project is urgent, I can start immediately and deliver an initial layout within 24–48 hours after receiving the DWG and requirements. I help clients design and deliver HVAC and MEP systems that work in real buildings, not just on drawings. I have designed HVAC and mechanical systems for hospitals, hotels, office buildings, commercial developments, and residential projects, including high-risk and technically sensitive environments such as operating theatres, isolation rooms, and critical facilities. My practical background includes: • HVAC system design (chilled water, VRF/VRV, DX, ventilation, heat recovery) • Load calculations, equipment selection, and energy-efficient system strategies • Healthcare, hotel, office, commercial, and residential MEP coordination • Code-compliant designs aligned with ASHRAE, CIBSE, HTM, NFPA, and international standards • Design reviews, value engineering, and constructability-focused solutions • Supporting permit submissions, tender packages, and contractor clarifications What clients value most is that I design systems with execution in mind. My solutions are buildable, coordinated, and realistic, reducing site issues, redesign cycles, and operational problems. I can support projects as: • HVAC & Mechanical Designer • MEP Design Reviewer • Technical Advisor for healthcare and complex buildings • Short-term problem-solver for urgent or stuck projects If you need a reliable engineer who understands both design intent and site realities, I can help. Designing building systems is not just about calculations and drawings. It’s about safety, comfort, efficiency, and long-term performance — whether the project is a hospital, hotel, office building, or industrial facility. I am a Mechanical & MEP Engineer with 19+ years of experience, delivering HVAC and building services solutions for healthcare, hospitality, commercial, and industrial projects across Europe and the Middle East. I work across the full project lifecycle — from concept and tender design to construction supervision, testing & commissioning, and final handover — ensuring systems are practical, compliant, and buildable on site. My background includes complex environments such as hospitals and healthcare facilities, as well as hotels, office buildings, and industrial/workshop projects, where airflow control, safety, comfort, and reliability are critical. ⸻ Core Expertise • HVAC & mechanical design for hospitals, hotels, offices, and industrial facilities • Critical environments: operating theatres, ICUs, isolation rooms, clean areas • Comfort ventilation, exhaust systems, dust and fume extraction • Medical gases, firefighting, drainage, water supply, and utilities • Compliance with ASHRAE, CIBSE, HTM, NFPA, JCI and international codes • Coordination with architectural, structural, electrical, and site teams ⸻ Project & Leadership Experience • Founder of Nilgoon Consulting Engineers, delivering 40+ MEP projects • Consultant for WHO-guided airborne isolation room projects (Ministry of Health, 2018) • Speaker at the National Congress on Hospital Construction & Healthcare Management (2019) • Proven ability to deliver projects on quality, schedule, and regulatory compliance ⸻ How I Can Help You Clients work with me to: • Design or review HVAC & MEP systems • Solve airflow, pressure, comfort, or compliance issues • Upgrade existing buildings to meet international standards • Support projects from early design through commissioning I am available for design packages, technical reviews, troubleshooting, and long-term support.
