I have extensive design experience (over 15 years) as a design engineer in overseas, working in Saudi Arabia, UAE, Qatar, Indonesia, Singapore, Sri Lanka and the Philippines. Currently I am based in Qatar, leading design teams on various projects. My design experience involved HVAC system, plumbing and fire protection system for medium and high-rise buildings, office and residential apartments, hotels, hangars, hospitals, and industrial applications in accordance with International Standards such as ASHRAE, NFPA, CIBSE and BS
