About Keisan

Get to know us a bit better

Creativity is intelligence having fun - Albert Einstein

Keisan ® was founded in February 2015 by Jillur Quddus, a computational mathematician and polyglot software engineer, with the goal of applying advanced analytics, machine learning and distributed technologies to vast volumes of disparate and unstructured data in order to solve real-world social, economic and geopolitical problems. We help organisations derive actionable insights from their disparate data assets by architecting, engineering and deploying scalable, resilient, high-performance and secure data intelligence platforms based on open source technologies and frameworks. Most importantly, we passionately believe in our 6 core values - Collaboration, Innovation, Imagination, Simplicity, Education and Dedication - whilst delivering real business value and driving organisational change.


温故知新 Learning from the past to understand the future

The name Keisan (pronounced 'K-San') comes from the Japanese word 計算 of the same pronunciation, meaning to compute or to calculate. Before Keisan was founded, Jillur worked across the world architecting and engineering distributed, scalable, resilient, high-performance and secure solutions used to combat serious organised crime, cyber-enabled crime, financial crime and fraud. Jillur has extensive experience of working within central government, intelligence, law enforcement and banking, and has spent many years leading high-profile and cutting-edge projects in Japan, Singapore, Malaysia, Hong Kong, Australia and New Zealand. Many of the themes found in Keisan are inspired by the Japanese language, including Ramus Mori 森, Bonsai 盆栽, Kodama 木霊 and of course our company name Keisan 計算!
