What I'm looking for

I seek senior roles applying ML-driven threat hunting and scalable data architectures in a collaborative, mission-focused team with opportunities to research, innovate and deploy production cyber-defence solutions.

I am a senior cyber security researcher with over 17 years' experience in research, software development and system architecture within Singapore's national defence R&D environment. I have deep expertise in cyber security, data analytics, threat hunting (MITRE framework, Cyber Kill Chain), and machine learning including Transformer models/LLMs, and I have led projects integrating proprietary algorithms with COTS big-data platforms (HDFS, Kafka, ELK) and Apache Spark for distributed processing.

My work includes developing host monitoring agents, penetration-testing to generate evaluation data, resource-allocation optimization algorithms, and practical exploits and reverse-engineering during my master's research in the USA. I am an effective communicator accustomed to collaborating with customers and international teams, and have been recognized with national and organizational awards for cyber security innovation.
