Work Experience

AI Engineer Intern | ClickNext Co., Ltd.Jan 2026 - Present
  • OCR & Frontend Services: Benchmarked and fine-tuned a Thai handwriting OCR model, reducing the Character Error Rate from 60.95% to 19.98%, and successfully deployed the solution through a Next.js frontend service.
  • Computer Vision & Speech Processing: Developed a computer vision and speech processing pipeline to extract structured data from live video clips.
  • Backend Development: Built a meeting summarization service utilizing FastAPI and LLM APIs, implementing structured text processing pipelines to optimize internal workflows.

Projects

Credit Risk Assessment & Lending SolutionsJan 2026 - Feb 2026
  • Built a predictive credit risk pipeline using machine learning models to generate reliable Probability of Default (PD) assessments from large financial datasets.
  • Enhanced lending decision strategies by integrating threshold analysis with risk-adjusted return optimization, enabling data-driven loan approvals that mitigate complex financial risks.
  • Applied isotonic regression calibration to ensure reliable and interpretable risk scores.
  • Identified an optimal PD threshold (22%) to maximize risk-adjusted returns and expected loan collection.
Video Anomaly Detection System using SlowFast and Adaptive MissionGNNAug 2025 - Mar 2026
  • Built a feature extraction pipeline using SlowFast (temporal) and ImageBind (semantics), generating high-dimensional combined representations from surveillance video data.
  • Extended the MissionGNN research model by concatenating SlowFast features with ImageBind features and evaluating the impact on anomaly detection.
  • Achieved 0.8484 mAUC on UCF-Crime and 0.7367 mAP on XD-Violence datasets.
Multi-Label Emotion Detection in Tweets (BERTweetMA)Jan 2025 - Feb 2025
  • Built a multi-label classification model using BERTweet with attention mechanisms on 38K tweets.
  • Designed emotion-specific attention blocks with sigmoid-based classification.
  • Achieved: F1-micro 0.728 | F1-macro 0.689 | Jaccard 0.699.
Task Tracking Web ApplicationMar 2024 - Aug 2025
  • Designed and developed a role based task management system for project tracking and cross-team collaboration.
  • Led frontend development and UX/UI design using NextJS to improve usability and workflow clarity.
  • Architected system structure including task status, role permissions, and project hierarchy to ensure scalable and maintainable design.
