Chulalongkorn University Language Institute (CULI) · Aug 2024 — Present
Architected and deployed the backend infrastructure for an AI-powered exam grading platform at Chulalongkorn University Language Institute (CULI), reducing manual evaluation time by 50%.
Presented system architecture and research findings at the IEEE TALE 2025 conference in Macau. Also demonstrated the platform at the "AI for Smart Admincourt" roadshow at the Administrative Court of Thailand.
Engineered a high-performance REST API using FastAPI with async background jobs for batch-grading. Integrated GPT-4 for handwriting OCR and rubric-based scoring, backed by PostgreSQL with vector search.
Containerized the stack with Docker, deployed secure file storage via AWS S3, and managed infrastructure with Terraform. Built CI/CD pipelines via GitHub Actions with automated pytest routines.
