## About

I work through code like I'm taking a system apart: find what's broken, rebuild it, then ship something that actually works. As an AI Engineer, Software Developer, and Researcher, my job is connecting three worlds into one: machine learning models that are accurate, web applications that are stable, and research that actually gets used, not just published and forgotten.

## Projects

### CritLit (cdl-ai.id)

Adaptive AI Education Platform. Adaptive AI platform built to measure and improve Critical Digital Literacy among teachers in Indonesia. Uses an IndoBERT based classification model to automatically detect 6 types of cognitive bias and framing with high accuracy, plus an adaptive testing system.

Tech: React.js, FastAPI / Python, IndoBERT Model, PostgreSQL
Live: https://cdl-ai.id
Metrics: 6 bias & framing types detected
Problem: Teachers in Indonesia need a practical way to measure and improve their Critical Digital Literacy, and spotting cognitive bias or framing in a text by hand does not scale.
Approach:
- Built the platform around an IndoBERT based classification model that detects 6 types of cognitive bias and framing.
- Served the model through a FastAPI backend, with a React frontend and PostgreSQL for data.
- Added an adaptive testing system on top of the classifier.
Result:
- Live and in use at cdl-ai.id.

### Desa Jagara (jagara.jastik.site)

Role: Research Assistant, AI System Development (Jul 2025 - Oct 2025)
Problem: Behavioral analysis experiments needed face, pose, emotion, and text models working together in one system, instead of as separate scripts.
Approach:
- Integrated pre-trained models (ArcFace, YOLO-Face, pose and emotion models) into a Flask API pipeline for experimental data processing.
- Built React interfaces and an interactive analytics dashboard to visualize the results.
