SUMMARY
Java Backend Developer with 2 years of experience building backend systems for fintech and crypto/AML
products. Worked with Java, Spring Boot, PostgreSQL, Redis, Docker, and Jenkins. Built external provider
integrations, asynchronous workflows, webhook-based communication, and backend services for crypto
transaction monitoring and AML checks. Contributed to performance and reliability improvements by moving
long-running synchronous operations to asynchronous processing, implementing observability with Grafana
and OpenTelemetry, and introducing the Outbox pattern for more reliable event delivery. Comfortable with
REST APIs, integrations, production logs, unit tests, and integration tests.
