Experience & Education

Professional engineering roles, applied AI research, and academic milestones.

Work Experience[ 04 ROLES ]
June 2026 – Present
IT Intern (ML & Data Science)
PT Astra Visteon Indonesia
  • Developed a data-driven monitoring system for industrial air compressors, analyzing 150K+ operational records to identify maintenance-critical conditions and support earlier intervention.
  • Introduced the company's first AI-based predictive maintenance system, improving maintenance-critical event detection recall from 0% to 60% through feature engineering and recall-focused model optimization.
  • Built an end-to-end monitoring pipeline with Python, SQL, and FastAPI, enabling real-time anomaly detection, automated alerts, and live operational monitoring.
Sept 2024 – Present
AI Engineer (Part-time)
HPC Universitas Gunadarma (HPC-UG)
  • Built a production-ready AI laboratory assistant that helps students troubleshoot laboratory systems and programming issues using a fine-tuned Qwen3-8B model and Retrieval-Augmented Generation (RAG).
  • Published peer-reviewed research applying deep learning (CoralNet, InceptionV3, MobileNetV2) to automate coral bleaching detection, achieving 89% accuracy to support marine biodiversity monitoring.
  • Deployed distributed AI workloads on NVIDIA DGX-1 and DGX A100 with infrastructure teams using Docker.
Feb 2025 – Aug 2025
International AI Summer Course Instructor
Universitas Gunadarma
  • Delivered hands-on training on Generative AI, NLP, and LLM applications to international students and academic faculty, bridging AI theory with practical implementation workflows.
