What I'm looking for

I’m looking for an Agile team where I can build secure, scalable backend services and user-facing React features—using clean architecture, REST APIs, and modern security (Keycloak/JWT)—while improving reliability with testing, CI/CD, and cloud deployments.

I’m a Full Stack Software Engineer with hands-on experience building enterprise-grade applications, with a strong backend foundation in RESTful API design and scalable system development.

At IronOne Technologies, I developed and maintained backend services for a wealth management platform using Java and Quarkus, designing REST APIs for scalability, maintainability, and secure data handling. I integrated Keycloak-based authentication and role-based access control, optimized SQL queries to improve API responsiveness, and managed schema versioning with Flyway. I also built responsive React.js and TypeScript components that connect cleanly to backend services.

I enjoy clean architecture, modular design, and collaborative delivery in Agile (Scrum), including code reviews and debugging to raise code quality. My projects reflect the same focus—event-driven microservices with Apache Kafka, JWT/OIDC security with Keycloak, and full-stack apps deployed with Docker and AWS.
