Experience

Serving as a Teaching Assistant for Artificial Neural Network and Data Mining courses, supporting students throughout the semester.

Led development of a real-time Facial Emotion Recognition (FER) system using deep learning for adaptive learning. Experimented with backbones (ViT-B/16, DINOv3, DaViT, EfficientViT, FaRL) for multi-head emotion classification. Evaluated image and landmark-based transformer pipelines via hyperparameter sweeps and ablation studies (PyTorch, W&B). Built dataset collection and configurable training infrastructure for scalable experimentation. Built the production inference API with FastAPI and ONNX Runtime, serving the FER pipeline via Docker and Gunicorn/Uvicorn with GPU acceleration.

Served as Teaching Assistant for Advanced Artificial Intelligence and Web Application Development. Designed live coding problems and authored midterm/final exams in Python. Supported 60+ students across courses with hands-on guidance and assignment grading.

Built a spam detector with DistilBERT and a multi-input BioBERT system that graded 51,890 medical articles across six quality categories. Development experiments reached 83.29% training accuracy and 0.87 ROC-AUC, while final held-out testing reached 61% accuracy and a 0.62 weighted F1-score, highlighting the impact of severe class imbalance.

Taught weekly lab sessions covering sorting algorithms, trees, graphs, and dynamic programming. Prepared live coding problems, graded assignments, and authored midterm/final exams in Java. Held office hours to help students debug and understand complex concepts.

Built a website for the village using ReactJS as the frontend and a Backend as a Service (BaaS) solution using PocketBase as the backend. Deployed the website on a Linux Virtual Private Server using Docker and Nginx as reverse proxy. Implemented rate limiting to prevent spam on the website.

Built a backend system in Golang using the Fiber framework, Docker, and PostgreSQL. Implemented authentication, authorization, and rate limiting to improve security and stability. Integrated Midtrans payment gateway to enable seamless transactions.
