Leading engineering at Contactter
I’m Tawan. I build AI products, connect complex systems, and turn curious ideas into software people can use, from Contactter, our automotive AI platform, to Opennan, every AI tool behind one API.
Based in Bangkok, Thailand.
From customer conversations to creative tools.
Different problems, the same hands-on curiosity.

I’m Thiatham Kongthong, Chief Technology Officer at Silent Partner AI (silentpartner.ai), the company behind Contactter. I lead the engineering behind its AI assistants, customer conversations, and dealership CRM integrations.
I started exploring programming through games and built my first websites before studying Computer Engineering at Khon Kaen University. Freelance projects grew into work on trading infrastructure, and then into my role as CTO at Silent Partner AI. I enjoy the whole process: understanding a problem, building the interface, connecting the data, and getting the product into people’s hands.
Outside the day job, that curiosity takes me into creative AI, trading tools, voice experiments, and game development. Space has always been part of the inspiration, too.
