Summary
Senior Tech Lead at ROSHN Group in Saudi Arabia, owning the technology behind the home acquisition platform — the digital buyer journey that takes customers from browsing a property to closing the purchase. I'm responsible for frontend architecture, the in-house design system, performance, and end-to-end delivery for one of Saudi Arabia's flagship real-estate brands.
Previously at CARSOME, I architected Martech tooling that streamlined marketing operations and dramatically cut third-party costs. Today, I split my time between leading at ROSHN and co-founding two product companies — OpenGenX (SaaS & blockchain solutions) and SalesTub (CRM for Indian B2B).
