About

Hey! I'm a data scientist/machine learning engineer who works on end-to-end artificial intelligence (AI) solutions from problem statement ideation, model development, all the way to production deployment in the financial sector. I have led and worked on AI projects that involve agentic large language model (LLM) systems, credit scoring, natural language processing (NLP), anti-money laundering (AML), nowcasting etc. I have also had the privilege of being the first data scientist/ML engineer at Aeon Bank, Malaysia's first Islamic digital bank, to build up an entire MLOps system on Kubernetes using open-source tools and productionize real-time predictive models. Occasionally, I develop Streamlit applications that consume and display model predictions because sometimes people need to see the magic in action to believe it! In a previous life, I was running around banks as an associate supervisor assessing their market, credit and operational risks. I was finding ways to make them manageable but eventually realized that the biggest risk of all was ignoring my growing interest in the field of artificial intelligence. That's why I had to make the transition. I'm also a strong believer in online education and continuous learning. In 2018, I enrolled in an online certificate program called the MicroMasters in Statistics and Data Science that claimed to offer graduate level university courses with the same rigor as the equivalent residential versions. The verdict: I entered a skeptical guy but left impressed and hopeful for the power and potential of online education. Finally, I enjoy mentoring people both in the technology space and in business/strategic thinking whenever I can squeeze in some free time. Young people inspire me because they have the courage to say and do the darnedest things.
