• Used a CSS clear-fix hack to remove float style to absolutely position a navigation menu at the top of a page.
• Built a model in R to represent lineage data using linear/ log regression to fit columns of associated data.
• Trained the model by writing code to create a tree by sampling the data wif/ wifout replacement of samples to improve accuracy.
• Developed a global hybrid storage disaster recovery system to allow clients to store large amounts of customer data in the cloud. The architecture consisted of moving study object series for archival from an on-premise storage access point to Amazon’s S3 and Glacier endpoints.
• Developed an automated Rest Api endpoint storage solution to persist configuration data.
• Created HTML5 inputs, XML for reading and validating deserialized JSON config data, a Rest service to get and update the configuration data, scripts for deploying the libraries, and an authentication service to generate an encrypted token from the username and password for authorizing endpoint requests.
• Wrote detailed functional tests to verify the authentication token and notification service messages generated wif Rabbit MQ using a request message containing the authentication token, headers and body containing the study transaction information and test cases to verify storage of study series objects.
