Portrait of Theeraphat Chueanokkhum
Full-stack + platform engineer Open to the right opportunity

Theeraphat Chueanokkhum

I design, build, and operate software from the interface to the cluster.

Five years across product UI, backend services, enterprise data, and Kubernetes. Currently shipping a nationwide oil-control platform for Thailand's Excise Department.

01 / Scope

I work across the handoffs.

The best systems are not a collection of disconnected layers. I stay close to the whole delivery path so decisions made in the interface still make sense in production.

Currently building and operating OCM, a nationwide oil-control system for Thailand's Excise Department.

Product delivery / platform ownership / production support

  1. Interface

    01

    Make complex work feel direct.

    I turn operational workflows into focused interfaces with clear states, fast feedback, and details people can trust every day.

    Next.js / Angular / TypeScript / Figma

  2. Services

    02

    Design services around the real workflow.

    I shape APIs, background jobs, and integrations so product behavior stays understandable as systems grow.

    NestJS / FastAPI / Node.js / Python

  3. Data

    03

    Keep critical records dependable.

    I work across enterprise and open-source databases, with attention to contracts, migrations, and the edge cases behind production data.

    Oracle / PostgreSQL / SQL

  4. Platform

    04

    Own the path into production.

    I package, deliver, observe, and operate the same software I build, using GitOps and Kubernetes to make releases repeatable.

    Kubernetes / ArgoCD / Harbor / Vault

02 / Selected work

Systems with real users, real constraints, and a production address.

My strongest work sits where product decisions and operational reality meet. Some projects are public; the enterprise systems are presented at the level their confidentiality allows.

OCM — Oil Control Management

The enterprise system I work on daily: oil-control management for Thailand's Excise Department. I build and operate it end to end — NestJS + Next.js microservices on Oracle and PostgreSQL, running on Kubernetes with a full GitOps pipeline.

03 / Experience

Built by shipping, then staying for production.

My work has moved from focused web applications into enterprise systems and platform ownership. The common thread is responsibility after launch.

04 / Working stack

A broad toolkit, with a deliberately narrow core.

I choose tools for maintainability and operational fit. These five sit at the center of my current work; the capability index below shows the wider range I can bring to a team.

  1. 01

    Next.js

    My go-to React framework for production apps

  2. 02

    NestJS

    Structured Node.js backend for enterprise services

  3. 03

    Oracle / PostgreSQL

    The databases behind the systems I run

  4. 04

    Kubernetes

    Where everything I build actually runs

05 / Credentials

No badges to show yet

I learn mostly by shipping. Right now I'm going deeper on Kubernetes operators and platform engineering — real certificates will land here when I've earned them.

06 / Contact

Need someone who can own more than one layer?

I am open to thoughtful freelance work and full-time roles where product engineering and platform responsibility belong in the same conversation.
