@sanaullahasif
Senior FinTech engineer building PCI-compliant payment infrastructure and scalable gateway integrations.
BangladeshWhat I'm looking for
I’m a payment infrastructure specialist behind shurjoPay’s transaction engine, with 9+ years solving fintech challenges across PCI DSS compliance, bank/MFS integrations, and scalable architecture. I’ve built fraud detection and compliance modules to keep payment systems PCI DSS compatible, and I’m now applying that experience to build a more robust payment system.
In my recent work, I architected a patent-pending payment gateway and integrated 15+ payment processors and banking APIs, while also leading migration from a legacy PHP monolith to Node.js microservices. As a team lead (8+ engineers), I helped drive Bangladesh’s fastest-growing fintech platform, achieving 99.9% uptime, delivering ahead of schedule, and improving transaction processing speed by 40% while reducing technical debt by 30% through clean code and SOLID principles.
