I'm an Industrial Software Engineer based in Cikarang, West Java, working at PT. Tosei Indonesia under the ACCRETECH brand. My career has taken me from writing PLC programs for precision measurement machines to programming ABB robots and deploying IoT API systems for major automotive manufacturers.

What makes my profile unusual is the full stack of industrial engineering I carry: I can read electrical schematics, configure servo motors, write ladder logic, build the HMI screen, develop the desktop application, and wire up the API that connects it all to the cloud. Clients include Toyota (TMMIN/ATI), Astra Honda Motor, Sunstar, Musashi, and more.

I thrive in environments that demand both hardware-level precision and software engineering discipline — factory floors where downtime is measured in millions.
