His achievements were recognized by the university through the Excellent Service Award which he received for more than ten times throughout his career so far.   He is involved in quite a number of consultancy work, bearing the responsibility as a Consultant in different projects such as Petronas Rapid Project on Groundwater Hydrogeological Regime Study, Monitoring and Scientific Research Works at Lake and Wetland Putrajaya Hydrology Project, Kelantan Groundwater Monitoring, Dry Weather Flow and Sedimentation in ‘Upper Bisa wetland’ Putrajaya, Horizontal Collector Well Projects in Kelantan and also as Expert Advisor for Program Pasca Banjir under sponsorship of CIMB, Media Prima, and MAA in Kelantan back in year 2015. Program Pasca Banjir is one of his notable contributions in giving back to the community.
