Senior🎓
Top SchoolMartinus Alexander is a Senior Data Scientist based in Singapore with 10 years of experience building production ML systems across fintech and e-commerce. He has delivered recommendation and search engines that measurably improved user engagement and penetration—leading projects that boosted mAP@20 by 6% and search penetration by 5%—and has hands-on experience with Spark, Scala, Java, Python and Elasticsearch. His background includes credit scoring and risk models that raised approval rates while holding default rates steady, plus NLP and image-recognition prototypes from earlier research roles. Now at GXS Bank after a senior stint at Atome, he combines product-facing teamwork with the engineering discipline to move models into low-latency, production environments. Colleagues know him for bridging deep technical work with practical business impact and for shipping end-to-end pipelines rather than just prototypes.
