At Sigma Software, I built and operated Kafka data-processing pipelines for ingestion, transformation, and enrichment, and developed Spring Boot microservices deployed with Docker, Kubernetes, and Helm.
I raised unit and integration test coverage by 60% and expanded test automation with JUnit and Cucumber. I also configured Keycloak security and documented backend services with OpenAPI.
On the Kanjigation Learning Platform, I designed, implemented, and deployed a microservice architecture for kanji, word, and sentence services. I led an international team of three from scope through release and built a reusable library for creating and transforming JSON objects.
At Table Nuevo Complex, I turned a plain Excel spreadsheet into a music database web service, working across its Angular frontend and Java backend. I covered the backend with unit tests to 80% and wrote a Python script to convert raw Word and Excel data into JSON.
