Full-stack developer & automation engineer — I build the systems that run your business behind the scenes, not just the parts people see.
Got a workflow eating your time? Client intake, follow-ups, data that lives in five different tools? I connect it, automate it, and make it run on its own.

Industrial Design student on the side — which means everything I build looks intentional, not like every other Fiverr template
