Founder Story

I build like an engineer. I decide like an owner.

My work sits where software and business meet: turning operational needs into systems that customers, teams, and founders can rely on.

As Co-Founder and Tech Lead at IPROG TECH, I lead Rails and mobile delivery, collaborate directly with CEOs, and ship systems that handle real production pressure.

That builder mindset extends to ventures like Ka Prets Pizza House, where software is shaped by actual customers and daily operations.
