I build scalable Java backend, streaming, and financial reconciliation systems across global fintech and ecommerce operations.
United StatesWhat I'm looking for
At PayPal, I build transaction fee processing and reconciliation systems handling more than 2 million transactions daily across 25+ currencies and 200+ markets. I’ve reduced Snowflake batch processing from six hours to minutes, improved warehouse query performance by about 30%, and automated pricing reconciliation with agentic AI workflows that reduced manual finance interventions by 60%.
Previously at Walmart and Best Buy, I built event-driven Java and Kafka platforms for inventory, pricing, orders, and customer-facing systems. I’ve migrated high-traffic workloads to DynamoDB, reduced database response times, designed scalable streaming architectures, and delivered reliable Spring Boot microservices on AWS.
I enjoy translating complex financial and operational rules into dependable software, with a focus on data quality, observability, auditability, and failure-safe processing.
