Initially developed Blockchain monitoring tool BlocWatch which later pivoted into SecureCloudDB.At BlocWatch, we created platform for performing blockchain monitoring, analysis, and, for private chains, configuration best practice verification.SecureCloudDB was a pivot to generalized database security monitoring and analysis. With SecureCloudDB, we built a scalable system that allowed advanced rules to be configured and verified enforced against cloud database systems.Technology used included: Java, Spring Boot, Kubernetes (EKS), Iceberg/Hive/Spark, AWS RDS, DynamoDB, Elasticsearch, Kinesis.
