About

I studied at the University of Edinburgh and spent a decade in enterprise technology consulting, leading data engineering teams for tier-1 organizations known for their complexity and scale. Most recently, I served as Director of Data Engineering at one of Asia's leading banks, where I led the team that delivered a data platform serving over a thousand active users and millions of customers — and drove the organizational changes behind it.

The hardest problems in data engineering are never technical — they are organizational

Today, I teach at the National Economics University in Hanoi — one of Vietnam's most prestigious universities for business and finance students — across six courses spanning fintech, leadership, strategy, technology, and professional development. Technology leaders need to understand business context and how to develop people, not just systems.

Outside of organizational leadership, I build AI data products as a practitioner — including multi-agent orchestration platforms — giving me a hands-on view of where AI creates real value and where it falls short.

Expertise

Enterprise Data Engineering

Leading teams that deliver data platforms at banking scale — zero-trust architectures, self-service analytics, and governance frameworks that enable rather than restrict. The best governance is structural, not procedural: design the architecture so policy enforcement is built in.

Technology Leadership

Leading and reorganizing engineering functions through periods of rapid change. Cross-cultural leadership across four countries, building high-performing teams, and making architectural decisions that shape how entire departments operate.

Education & Future Leaders

Developing the next generation of business and technology leaders at one of Vietnam's most prestigious universities. Six courses — from fintech to leadership — built around one conviction: the world is splitting into those who know how to deeply leverage AI and those who don't. I teach on the right side of that divide.
