At CoinRoutes.com, I designed and built a real-time risk-management system that evaluates and restricts orders in under 1ms. It applies configurable exchange-, coin-, and organization-level rules and handles 100 requests per second for 70 clients.
I also cut inter-service latency by over 30% by moving feasible WebSocket communication to gRPC and Protobuf. I tuned PostgreSQL queries on Amazon RDS, reducing one slow query from 2 minutes to 20 seconds.
At K•tim LLC, I led development of Java and Spring Boot APIs for user management, integrating Keycloak with Active Directory for OAuth 2.0 and OpenID Connect authentication. I also decoupled the service from its policy engine with Apache Kafka and Spring Batch, processing up to 250 requests per second.
Across fintech, crypto trading, and property platforms, I’ve developed backend services and integrations, including a remittance and foreign-exchange platform at Al Ansari Exchange that processed 120k–150k transactions per day. I have 10+ years building distributed systems and microservices, primarily with Java and Spring.
