Career Profile
With over 16 years of diverse technical experience spanning healthcare IT and quantitative finance, I bring a unique blend of domain expertise and technical depth. My 10 years in healthcare have focused on transforming healthcare delivery through technology—modernizing Hospital Information Systems (HIS), developing intuitive clinical interfaces, and creating integrated data access platforms that enable healthcare providers to retrieve patient information from a single platform. Prior to healthcare, I spent 6 years in quantitative finance, designing and implementing quantitative algorithms, building time-series data warehouses, and developing trading models for financial products. This cross-domain experience, combined with expertise in modern infrastructure (microservices, Kubernetes), AI, and data science, allows me to excel in system architecture, data management, and data analytics applications.
