I've built high-availability Java and Kotlin microservices for HYPR's distributed SaaS identity platform, including secure REST APIs and authentication services using OAuth2, OIDC, and Keycloak.
I improve reliability and performance through Redis caching, SQL optimization, load testing, production incident response, and root-cause analysis. I've also resolved high-severity security vulnerabilities and supported automated CI/CD release processes.
As Integrations Lead at Crqlar, I led system design, planning, and code reviews while building Java/Kotlin services connecting third-party systems. I optimized external-data pipelines through batching, caching, API improvements, and efficient PostgreSQL schemas and queries.
My background also includes backend development for ERP and CRM systems, database migrations and validation, and teaching Java, Spring, Hibernate, SQL, and backend development programs.
