TECHNICAL PRODUCT BUILDER
I build software that survives production.
Tech Lead · Product Owner · Fullstack Engineer
I turn complex business problems into reliable production systems — from product discovery and system architecture to engineering, infrastructure, and delivery.

ENGINEERING JUDGMENT
Good engineering is not about choosing the most complicated technology. It is about making the right trade-offs.
Why PostgreSQL instead of MongoDB?
CONTEXT
A business system requires strong relationships, transactions and reporting.
DECISION
PostgreSQL
TRADE-OFF
More structured data modeling, but stronger consistency and relational querying.
Why Docker Compose instead of Kubernetes?
CONTEXT
Early-stage enterprise systems with single-node or vertical scaling requirements.
DECISION
Docker Compose
TRADE-OFF
Reduced operational complexity and maintenance overhead, at the cost of automated horizontal scaling.
Why separate staging and production?
CONTEXT
Replicating production issues and testing deployments without affecting real users.
DECISION
Fully isolated environments
TRADE-OFF
Increased infrastructure costs, but significantly reduced risk of production downtime.
How do we deploy without downtime?
CONTEXT
Business operations that cannot afford maintenance windows.
DECISION
Blue/Green or Rolling Deployments
TRADE-OFF
More complex CI/CD pipelines, but seamless user transitions and instant rollback capability.
I started by writing code. Then I learned to build systems. Now I care about the whole product.
DEVELOPER
Learning to build software.
FOUNDER
Learning product, customers, and business.
TECH LEAD
Learning architecture, teams, and delivery.
TECHNICAL PRODUCT BUILDER
Connecting product, engineering, infrastructure, and operations.
THANH HAU — NOW
I enjoy working on difficult problems where business requirements, technical constraints, and real-world operations collide.
BUILT FOR PRODUCTION
I don't just build software. I run it.
01 / ISOLATION
Strict environment separation between staging and production to ensure zero-impact deployments.
02 / OBSERVABILITY
Integrated monitoring and logging at every layer of the stack for proactive incident response.
03 / AUTOMATION
Fully automated CI/CD pipelines with containerized workloads for consistent delivery.
