As a core team member worked on building risk platform for scalability and performance. Efforts included:

• Adopted event based architecture for each user interactions.

• Designing and developing service gateway for risk ecosystem.

• Defining service APIs for Risk, Compliance and Limits interactions in PayPal transaction flow.

• Defining the domain boundaries and rearchitecting the service/data interactions.

• Simplifying code base by refactoring it and creating abstractions based on domain models.

• Latency improvement by reducing the critical section and moving non-critical functionalities to non-realtime processing.

• Parallel data processing and Rule engine integrations for dynamic business logic injection.

• sharding and latency bridging enabled risk data model for scalability and geo partitioning

Worked for PayPal

• Worked on multiple projects related to fraud risk managements during pre and post transaction. Efforts included:

• Moving code behind the service and migrating clients to use the new service end points

• Code optimization and performance/latency improvement by reducing the critical section for database operations

• Built an orchestration service to interact with external vendors for KYC

• I mostly contributed to API changes related to aggregation and consolidation of results from various external apis.
