Summary
Senior Platform Engineer @ PayPal with 9+ years of experience building and scaling high-impact web platforms used across 200+ countries.
Over the past 5+ years, I’ve evolved from an individual contributor into a de-facto tech lead—driving cross-functional initiatives across WebOps, SEO, AI/AEO, and platform engineering. I specialize in designing scalable systems using React, Next.js, Node.js, and microservices architecture, with hands-on experience in micro frontends, distributed systems, and cloud-native deployments on AWS (Docker, Kubernetes).
I focus on delivering real impact—improving developer productivity, enabling reliable systems at scale, and solving complex engineering problems with strong system design and data structures fundamentals. Highlights include reducing onboarding time by 40% and cutting deployment errors by 90% through automation, while maintaining zero critical production incidents.
Passionate about mentoring engineers, shaping architecture, and bridging business + engineering to deliver measurable outcomes.
