Software engineer with 4 years of experience, focused on blockchain, smart contracts, digital asset security and custody. Bulding scalable and reliable back-end services that bring blockchain innovation into real-world financial solutions. My experience involves developing microservices using Java Spring Boot, with expertise in MySQL, Kafka/Pub/Sub and GCP cloud environments, among other technologies. I have also worked as a mobile developer with Flutter/Dart. This background has given me a broad perspective on system integration and how different layers of technology connect to deliver a seamless product experience. Passionate about technology that creates real impact — especially when it blends security, innovation, and collaboration. 👩🏽‍💻 Github: https://github.com/vivianeor Blockchain | Smart Contracts | Custody | Security | Java Springboot | MySQL | Kafka | Pub/Sub | GCP | Datadog | Flutter | Dart | Mobile
