Building and scaling the core payments and notifications infrastructure that powers hundreds of millions of transactions daily.

Led the architecture and implementation of a high-performance batch processing pipeline handling ~750M financial records per day, leveraging Couchbase for real-time data transformation and microservices-based caching to serve downstream applications reliably at scale.

Drove a foundational overhaul of PayPal's transaction processing architecture — introducing asynchronous stage processing and message queues for post-payment workflows, resulting in a 46% improvement in transaction processing speed and a 72% reduction in failures during high-volume peaks. Applied two-phase commits and rigorous data validation to eliminate consistency issues at scale.

Championed engineering excellence across the team — leading CI/CD automation and code quality initiatives that cut release cycle time by 50%, enabling faster, safer deployments without sacrificing reliability.

Passionate about distributed systems, high-throughput financial architecture, and building engineering cultures where quality and ownership are non-negotiable
