// about me

Who Am I?

Iโ€™m an Electrical Engineering and AI/ML engineer building practical AI systems from research to deployment.

My work spans deep learning and computer vision research, LLM-based applications, and IoT systems. I build conversational AI with FastAPI and the OpenAI SDK, run open-source LLMs and vision-language models on local GPU infrastructure, and turn trained models into usable applications and APIs. I also work with ESP32 and embedded systems to connect AI with real-world devices.

My foundation is in deep learning and computer vision, with hands-on experience in PyTorch, data pipelines, model evaluation, and deployment. I am interested in the full AI engineering stack, from model development and prompt engineering to API design, local inference, and edge deployment.

I use autonomous coding agents to move faster, but I do not outsource the engineering thinking. I make the architectural decisions, understand the systems I build, and stay responsible for the implementation from end to end.

My Journey

AI Researcher โ€” Coffee Bean Grading System

Syiah Kuala University

Aug 2025 - July 2026

Developed an end-to-end computer vision pipeline in Python and PyTorch for automated coffee bean defect detection. Built an auto-labeling tool used to annotate 11,000+ images, trained and benchmarked multiple object detection models, and developed a Mosaic Packed Augmentation method for dense-scene detection. Results exceeded 85% mAP on the test set, with 3 research papers authored from the work.
