01 / APPROACH

Not “AI for the sake of AI.” I find the manual bottleneck, shape the flow, and build the smallest product that solves it.

03 / ABOUT

I build at the intersection of product thinking and engineering.

Before writing code, I spent more than three years inside an EdTech business — working with LMS, CRM integrations, feedback systems, and operational automations. That experience shaped how I build today: start with the real process, then choose the technology.

I use AI coding tools as part of the workflow, while keeping architecture, product decisions, verification, and the final result under deliberate control.
