Hello, I'm Thuan
Building software.
Making it work for people.
I work across identity, software architecture and the many decisions that help teams deliver and care for their products.

A little about my work
Curious by nature.
Practical by necessity.
My work has taken me across many areas, but I would hesitate to call myself an expert in most of them. Identity management is where my experience runs deepest; in security, I am still learning every day.
I am the lead architect of Safewhere Identify, and I work with teams on identity platforms used by public and private organisations. Beyond that, my days can range from helping run RIT Vietnam and guiding projects to investigating a difficult production issue.
I enjoy connecting the details to the bigger picture: understanding what a customer needs, helping a team find a workable direction, and staying close enough to the code to see it through.
What I bring
Experience across the work
From the first conversation to the systems people depend on every day.
Architecture & engineering
Designing and modernising .NET systems, working through integrations and compatibility, and finding the cause of performance and production problems.
Projects & people
Turning business and regulatory needs into plans, priorities and practical designs. I work with customers, teams and other suppliers, and help support the day-to-day running of RIT Vietnam.
Security & AI in development
Helping teams build security into their work through threat modelling, reviews and testing. I am also introducing AI-assisted development workflows, with people reviewing the results.
