About
I’m Sundara Pandian, a staff-level full stack software engineer with 20+ years of experience building high-impact fintech and payments platforms, including 15+ years at PayPal. My work focuses on consumer P2P and payments, open banking integrations, and compliance/risk systems—bringing together strong Java/Spring backend foundations with modern web engineering using React, Next.js, TypeScript, Redux, Node.js, and GraphQL.
I enjoy leading cross-functional delivery with Product, Design, Backend, Risk, and QA, and I’m especially proud of shipping production-ready features with near-zero defect rates. I’ve led initiatives like PayPal Link (reusable link-creation flow) and Fee Transparency improvements, modernized frontend architecture across multiple money-related flows, and helped teams move faster with AI-assisted development and improved test tooling. I’m also passionate about mentoring engineers and raising the bar through architecture and code reviews.
