Electrical Engineer | IoT Development · AI Engineer · PCB Design · AI Annotation

Electrical and Electronics Engineer with hands-on experience delivering end-to-end engineering solutions across embedded systems, AI-based computer vision, and PCB design.
I have built and deployed a custom object detection pipeline using YOLOv11s achieving 98.4% mAP@0.5 handling everything from raw image collection and manual annotation in LabelImg to GPU-accelerated training and real-time inference. I understand AI datasets from the inside, which means I annotate accurately and efficiently.
On the hardware side, I develop ESP32 and ESP8266 IoT systems with web dashboards, sensor integration, and relay control. I have also designed custom PCBs in KiCad including a redesigned ESP-01 breakout board that resolved voltage limitations and breadboard incompatibility in the official module.
My professional background includes RF network optimization at Huawei, where I audited live 2G/4G/5G parameters across 5,000 to 10,000+ base stations on the XL Smart Indonesia network building complex Excel workflows and delivering weekly summaries to GSC China frontline teams.
I take every project seriously regardless of size. Message me with your requirements and I will tell you honestly whether I can help and how quickly I can deliver.
