Assisted and advised on ad-hoc machine learning, visualization and automation projects. Prominent work involved writing a customized EM clustering algorithm to sidestep problems faced with conventional algorithms  helping the team to carve out an analytics project roadmap. Engaged CAAS’s Aeronautical Telecommunications & Engineering Division (AT&E) to identify advanced analytics opportunities Worked closely with the Surveillance Projects Section to develop a big data anomaly detection software Utilized PySpark to process transponder data to detect anomalous flight data transmission Constructed quality metrics and leveraged on Tableau (Reader) to provide low cost and user accessible visualizations Conducted pre-sales activities to understand the customer’s intent and vision Conducted presentations, workshops and active engagements to inform the customer on the Advanced Analytics (AA) landscape, helping them to align their business problems with AA solutions Efforts helped to pave open a project opportunity to enhance CAAS’s transponder processing and reporting capabilities Other key Activities: Rapidly developed a Topic Modelling Deep Learning library to increase value preposition for a project opportunity  Developed an integrated R and C++ “Mixed Distribution Mixture Model” clustering library for the team Developed customized fraud detection algorithms for NCS procurement fraud analytics product suite Actively participated in presales and tender activities, helping to understand customer’s objectives, assess their current capabilities and propose customized advanced analytics strategies to bridge the gaps Accounting and Corporate Regulatory Authority  Product Development (Manager), Information Resource Department       – Jun 13 – Oct 15 Identify opportunities to conduct statistical research and analysis to aid the organization in its policy and decision making process Provided insights and recommendations on policy making and operational process optimization to the Compliance Division by merging, analysing and forecasting huge complicated datasets. Collaborated with the enforcement department to leverage on analytics and visualization tools to raise Singapore’s corporate governance standards. Enhanced the product development process by complementing it with market segmentation theory to sieve out customer segments and analysing their needs. (Won 2nd prize in an internal competition for the project) Coded a range of market segmentation algorithms using new machine learning techniques and models. Fully establishing an array of clustering tools offering a choice of accuracy or speed.  Completed a working paper on: “Customer Segmentation using Dirichlet Process Mixture Models” Strategize and carve out new avenues to proliferate and enhance the use of Singapore’s business data to reduce information asymmetry and facilitate the business community’s inherent self-governance mechanisms. Conceptualized and initiated plans to leverage on cost effective Business Intelligence tools to increase the community’s awareness of ACRA’s rich datasets, understand its complexities and appreciate its economic value. Formulated novel business strategies to boost revenue for cost recovery and future system enhancements. Other notable experience and achievements: Involved in the full process of design, review and UAT of ACRA’s revamped IT systems. These includes ACRA’s intranet, public modules, BizFinx and QlikView Business Intelligence interfaces. Worked and engaged various HODs and colleagues to consult and advise on the adoption of analytic tools.
