How I work

One system, not a pile of parts.

I follow information from the interface to the infrastructure and back to the people operating it.

Read across boundaries. Keep the state explicit.

Public systems need useful speed.

At Da Nang IOC, I worked across map interfaces, Go services, IoT ingestion, and public monitoring for rain and flooding.

Interfaces and pipelines connected to real public-service operations.

State belongs in the design.

At TravelThru, I build transactional booking, driver, supplier, and synchronization workflows with explicit state transitions.

DDD-oriented services backed by MongoDB, PostgreSQL, Redis, and database transactions.

The edge cases are the integration.

I map partner APIs, timezones, webhooks, errors, and operational exceptions into workflows teams can run reliably.

From technical scope and estimation through production delivery and troubleshooting.

A practical toolkit.

Languages and platforms change. The constant is choosing what fits the system, team, and operating conditions.

Languages

TypeScript / JavaScript / Go / PHP / Java / C# / SQL

Backend and data

Node.js / NestJS / Laravel / PostgreSQL / MongoDB / MySQL / Redis

Web and maps

React / React Native / Expo / Vite / Google Maps / Mapbox / PostGIS

Infrastructure

Docker / Linux / AWS EC2 / Coolify / Nginx / Cloudflare / n8n

Read the whole system

Application code, databases, APIs, infrastructure, and operations are one problem surface.

Own the path to production

I am comfortable moving from requirements and architecture to delivery, debugging, and maintenance.

Use architecture to remove friction

Patterns matter when they make state clearer, failures safer, and operating work simpler.
