About
I turn repetitive work into infrastructure.
I'm Gian Benedict Bigay, an Automation Engineer who works mostly in n8n. For client brands I designed and ran the content engines, multi-platform distribution and CRM reporting that kept them publishing daily without anyone touching a keyboard.
Outside the pipelines I build the products themselves: an offline-first Flutter finance app, a booking system for my university, and a PHP e-commerce store. Same habits everywhere: shape the data once, fail loudly, make every run safe to repeat.

Have a process worth automating?
Send the brief the way you would explain it to a colleague. I'll propose an approach, you gut-check it, and I build the whole thing in one drop.
