About Me
I'm Chaidar, a backend developer and Physics student based in Madiun, Indonesia. My journey began with electronics and geophysics, but I quickly found my passion in building scalable web services and automation tools for disaster mitigation.
I specialize in Node.js, Redis, Docker, and ONNX/TFJS-based AI inference. I've developed government-level systems and led backend for AI-based evacuation projects that integrate real-time geospatial data and machine learning. I'm also comfortable working remotely and independently with modern DevOps tools.
When I'm not coding, I enjoy experimenting with ESP32 or writing about disaster tech. Let's connect and collaborate on something impactful.
