PROFILE

Wobu

Worked on backend systems in Java, focusing on reliability and extensibility across two open-source repositories. In Apicurio/apicurio-registry, delivered an Avro Logical Type Converter SPI to streamline Avro conversions, making default converters public and removing duplicate decimal conversions. This improved maintainability and enabled easier integration with new Avro types, while code quality was enhanced through immutable collections and comprehensive Javadoc. Later, in apache/iceberg, addressed a critical bug in the manifest rewrite flow by correcting file copy logic and expanding unit tests to prevent regressions. Applied skills in API design, Avro, and unit testing to ensure correctness and long-term stability.
