> I design complex financial and AI products that ship. Most recently, sole founding designer at OCTA (Abu Dhabi, $5.6M funded) — built 2 products from scratch, cut enterprise reconciliation from 2 hrs to 30 min. 14+ years, 80+ products, 26 designers led across 3 founding-team roles. I prototype with Claude and Cursor daily, from problem to testable interface in hours. Clients across the UAE, the US, and 6 countries. Available immediately.
