Jakkapan Sirirat

Backend & Full-Stack Engineer

I build backends and full-stack systems with Go and NestJS, take them to production with Docker and CI/CD, and automate business workflows with AI (n8n and LLMs). I care more about things working in production than looking good on a slide.

About

Making things that work

I work across the whole stack but spend most of my time on the backend.

GoNestJSKubernetesTypeScript

I'm a third-year Computer Engineering student at Kasetsart University with over a year of professional experience in software engineering and AI automation. I've shipped production systems โ€” a platform for KU's national agriculture fair and backend services for the university โ€” and I'm building a rental marketplace startup.

Day to day it's mostly Go and NestJS, with Next.js when I need a frontend. I like things simple, observable, and actually holding up when real people use them.

Kubernetes, GitOps, CI/CD โ€” the boring stuff that matters

Distributed Systems

Event-driven with Kafka & Redis when you actually need it

AI Automation
