Myself
I'm an IoT systems engineer based in Indonesia. At work I design, deploy and maintain complete IoT solutions: the hardware, the embedded firmware, the network, the cloud side and the operations after launch.
I hold a master's degree in information systems; my research classified deception from wearable PPG signals. Outside work I build developer tools and open-source software in Python, Go, Rust, C# and TypeScript.
