Kridsadar Ngankhayan
Full‑Stack Developer & IT Systems Engineer — from Arduino to enterprise servers.
10+ years turning IT support tickets into full-stack products: web, Windows, mobile, IoT and the infrastructure that keeps it all running. Based in Prachinburi, Thailand.
On the Job
Screens, cabinets and code from real deployments — dashboards, IoT builds, computer vision and networking.
Programmer at heart,
sysadmin by necessity.
I started in IT support — fixing printers, wiring networks, keeping servers alive — and grew into a full‑stack developer who still understands the infrastructure underneath the code. That combination means I build software that actually survives contact with real hardware and real networks.
Over six roles since 2013 I've shipped web apps, Windows software, mobile apps, Arduino/IoT devices, and the ERP, CRM, barcode and networking systems that hold a factory or hotel together.
