Tuan NguyenFullstack developer in Houston, Texas
For more than twenty years I've designed, built, and shipped web applications for startups and established businesses — from the first line of code through launch, and the operational work that keeps a product healthy long after. I build the whole thing: the data model underneath, the interface on top, and the automation that removes the work in between.

02Capabilities
What I actually build.
- 01
Backend & APIs
Laravel and PHP services, relational data modeling that survives contact with real usage, and documented APIs other teams can build against without a call.
- 02
Frontend
React and modern JavaScript, with performance and interaction detail treated as requirements rather than polish added at the end.
- 03
SaaS architecture
Multi-tenant systems, billing flows, and deployment infrastructure on platforms like Railway — including the tenant isolation and idempotency work that only shows up under load.
- 04
AI integration
Practical AI inside products that already have users: retrieval, generation, and agent workflows wired into real data, not demo scripts.
- 05
Automation & CRM
Removing the manual steps between a lead, a project, and an invoice, so a small team can run an operation that would otherwise need hiring.
03Proof of work
Products running in the open.
The clearest way to judge a developer is to look at what they keep alive. These are mine — live, maintained, and open to inspection.
04Method
How the work gets done.
- 01
Scope
Start from the business outcome, not the feature list. Most briefs shrink once the actual constraint is named.
- 02
Architect
Decide the data model and the boundaries first. Everything expensive to change later gets decided here.
- 03
Ship
Small, releasable increments in production early, so feedback arrives while changing direction is still cheap.
- 04
Operate
Logging, retries, and rollback paths. A launch is the start of the work the product actually lives in.
05Editorial
Why I write here.
Ask Tuan is where I publish what building real products teaches me — the problems I hit, the decisions behind them, and how they turned out. The point is practical, experience-based writing on fullstack development, AI, SaaS, and automation. Not recycled theory, and not a summary of somebody else's documentation.
If something here is wrong, I'd rather hear it. Corrections go straight into the page and the review date moves with them.
