• Engineering lead for turnkey projects in Southeast Asia, spanning Xylem’s product portfolio, including disinfection, aeration, and pump systems.
• Managing a cross-functional team and led the preparation of detailed engineering documentation for client submissions, securing project approvals. Adapted designs to align with client specifications and design.
• Key projects delivered or being executed include:(i) Ozone disinfection system for Rasau 700 MLD WTP in Malaysia.(ii) Five diffuser aeration systems for PUB Changi and Tuas WRP in Singapore.(iii) Over 30 pump projects.
• Enrolled in Xylem’s Innovation Technology Leadership Program and developed a Generative AI-driven web-scraping tool that reduced lead identification time from 3 hours to 10 minutes for sales teams in the US and Europe.
• Designed an ultrafiltration-reverse osmosis emergency drinking water system capable of treating variable salinity feedwater to provide for 1,000 displaced individuals during disaster relief.

• Collaborated with the National University of Singapore to create a machine learning model that integrates reaction kinetics to predict chlorine concentrations in the drinking water pipelines and co-authored a research.
• Conducted hydraulic simulations of Singapore’s drinking water network using EPANET as part of the research project. As a Kaizen initiative, I wrote a Python script that processes data into string files that can be read.
• Provided market intelligence insights using Python web scraping and Natural Language Processing to support the Business Development team.

• Contributed to the project management, process design, and commissioning activities for the Marina East Desalination Plant in Singapore, the world’s first dual-source desalination plant capable of taking in seawater.
• Package-in-Charge of several system suppliers: Aqseptence Johnson Intake Screens, Nijhuis DAFs, Amiad Strainers, Pentair Ultrafiltration, Nitto Denko Reverse Osmosis, Energy Recovery Inc’s Energy Recovery Device, IM.
• Evaluated and optimized vendor engineering designs to ensure compatibility with overall plant systems, addressing integration challenges and improving efficiency.
• Oversaw Factory Acceptance Testing to confirm compliance with design specifications, resolved punch list items, and ensured system functionality.
• Served as one of four lead engineers during plant commissioning, coordinating the seamless operation of all systems to achieve target plant throughput.
• Played a pivotal role in the thorough evaluation and refinement of process designs for multiple water packages essential for the Singapore Tuas Nexus Waste-to-Energy Facility and the Hong Kong Integrated Waste.

Singapore

• Led the engineering design of cutting-edge membrane filtration systems with the use of Cembrane’s flat sheet ceramic membranes across several industries in Southeast Asia.
• Served as the technical lead for high-impact tenders:(i) Ceramic membrane bioreactor (MBR) facility bid at PUB’s Changi Water Reclamation Plant with Ovivo.(ii) Developed a proposal for a ceramic membrane-reverse.

Singapore

• In charge of structural engineering and the design of ex-proof analyser containers to house analyser systems for measuring process stream conditions for petrochemical plants.
• Design, built and delivered 52 ex-proof analyzer systems (USD 7M) to ExxonMobil Singapore, enabling real-time process data measurement for butyl rubber production.
• Engineered and supplied 208 explosion-proof containerized analyzer systems to Kuwait National Petroleum Company (USD 25M), the largest project in the department’s history.

• Responsible for the process design, piloting and commissioning of ultrafiltration systems using LiqTech’s silicon carbide ceramic membranes.
• Provided technical support directly to the General Manager in penetrating the markets in Malaysia, Indonesia, Australia, China, Thailand, South Korea and Japan.
• Conference speaker at IndoWater 2013 (Indonesia) on the subject of ‘Application of Ceramic Membranes in the Oil Industry’. Generated new leads with Pertamina; Indonesia’s state-owned oil and gas company.
• Key projects include:1. Delivery of an ultrafiltration skid for the treatment of highly alkaline wastewater (Singapore, Mar 2013).2. Pilot study on the dewatering red algae for the manufacturing of health supplements.
