He started his sustainability and building physics career in Dar Group as part of the Beirut office Sustainability team, and later on co-founded specialised consultancy firm "SEEDS International", where he led the company's various departments and successfully directed turnkey high-profile projects across the MENA region, among which the Dubai Expo 2020 UAE Pavilion, SABIC HQs in KSA, Meydan One Mall in Dubai, Bahrain Airport new terminal building, and the Lebanon Waterfront City.
