Karahan Sarıoğlu

At The Despatch Company, I led the UX redesign of warehouse order-management modules used by 1,500+ daily active users across 40+ client warehouses. My work reduced picking and packing completion times by 18–25%, lowered usability-related support tickets by approximately 25%, and improved first-time configuration accuracy.

Previously at Innoscripta, I led and mentored a three-person design team while defining UX and brand direction for Turkish operations. I designed AI-powered project and document-management modules for 500+ enterprise users and led a rebrand that increased digital engagement metrics by 30%.

I've also delivered product, brand, and design-system work at Jeffromi Studio and Engcode, including DeFi, NFT, fintech, SaaS, food delivery, and consultancy products. I use research, usability testing, prototyping, and scalable components to turn complex workflows into clearer experiences.

I'm particularly interested in behavioral psychology, human-centered AI, and interactive systems, and I bring a computer engineering foundation to collaborative product design.
