Java Software Engineer at Agile Actors, contributing to Interamerican’s multi-currency reinsurance redesign and REST APIs.

Greece
Message

At Agile Actors, I work on Interamerican’s core insurance platform, contributing to a redesign of its reinsurance module for expansion into Romania. The redesign added multi-currency support while keeping existing portfolios, including Property & Casualty, backward compatible.

I’ve also contributed to REST APIs documented with OpenAPI, taken part in moving API specifications to IBM API Connect, and maintained SOAP services. I integrated external geospatial services so insured addresses carry coordinates used in pricing.

At the Technical University of Crete, I implemented SaaMS, a microservice-based system for scalable stream summarization using Java, Apache Kafka and Kafka Streams. My thesis work was published in Information Systems (Elsevier).
