## About

```text
At Sika Financial Group, I develop Java and Spring Boot microservices for financial trading, FX pricing, rates, funding, and settlements. I designed a Parallel Rate Calculation Engine that aggregates liquidity-provider sources and calculates rates with confidence handling and immutable audit snapshots.

At Citibank – Risk Technology, I led the migration of a mission-critical risk platform from a monolith to cloud-native Spring Boot microservices on AWS, achieving 99.9% uptime and daily on-demand releases. I also developed distributed ETL services processing more than 8 million records per day.

At Oracle, I built a Spring Boot Operations Dashboard for consignment booking and tracking, supporting 12+ 3PL clients and 35K+ daily transactions. I also developed integration microservices and services for ship-node prioritization and notifications.
