What I build

Selected work in computer vision, agentic AI, and backend systems.

Computer Vision

Mining Eyes: Real-Time Safety Monitoring Across 15+ Mining Sites

Seven computer vision products running on 24/7 CCTV feeds from more than 24 cameras. Two years of work that cut workplace incidents by 40% and lifted operational compliance by 60%.

Computer Vision

Pushing Mining Detection to 86.5% mAP@50 with YOLOv8 and BGF-YOLO

My final project at ITB, and the direct answer to what YOLOv4 kept getting wrong in production: small objects, bad lighting, and confident false detections.

LLM & AI Agents

An LLM Agent That Runs the Entire Sales Flow, From Browsing to Payment

A multi-agent system built on LangChain and LangGraph that handles product discovery, cart operations, shipping quotes, order creation and payment inside one conversation. 60% faster than the standard checkout flow.

LLM & AI Agents

Agentic AI for Sales and Lead Generation, Shipped as a Real Product

Multi-agent bots for sales and lead generation, plus the unglamorous half nobody writes case studies about: authentication, plans and billing, built end to end across Rails and Vue.

Computer Vision

Real-Time Text Detection in Video with EasyOCR and OpenCV

A lightweight OCR pipeline that reads text frame by frame, draws it back onto the video and writes an annotated output file. Small project, direct answer to a common video analytics need.
