Building production systems — from AI pipelines grading thousands of exams to hybrid Kubernetes clusters with zero open ports.

About
I build backend systems, AI pipelines, and production infrastructure. My work includes an AI exam grading platform processing thousands of handwritten exams for Chulalongkorn University, a hybrid Kubernetes cluster spanning home servers and cloud edge nodes with zero open ports, and a C2C marketplace with custom escrow payments built in Go.
I co-authored a peer-reviewed paper presented at IEEE TALE 2025 in Macau, placed top 10 nationally in Thailand Cyber Top Talent 2025, and have won multiple hackathon awards. I gravitate toward problems that demand reliability at scale — async job pipelines with retry logic, vector similarity search for few-shot learning, and infrastructure-as-code across Terraform, Ansible, and GitOps.
Second-year Electrical Engineering student at Chulalongkorn University, specializing in Communication Engineering.
Currently open to software engineering internship opportunities.
