Zubair R.

Need a full stack developer to build or scale your lending, payments, banking or SaaS platform? I've architected systems that helped one client secure 100M euros in funding, and delivered 28 projects with a 4.98 rating on Upwork. I combine 12+ years of full-stack engineering with deep fintech domain knowledge, spanning digital wallets, lending marketplaces, KYC/AML compliance, and Open Banking integrations. On top of that, I build AI agents and automation systems, so I can add intelligent workflows, document processing, and conversational AI on top of the financial platforms I build. Few developers cover both the regulatory complexity of fintech and modern AI tooling. One client wrote: ⭐⭐⭐ "Zubair built a P2P fintech platform for us that helped us secure €100M in funding. His technical expertise, architecture decisions, and product thinking were instrumental to our success."
