Built key back-end services (Apache Thrift and Jersey REST) that facilitated retrieval and storage of physician order content from HBase database to iOS application. Wrote modularized code using Google Guice as injection framework and JBehave-based functional tests.

• Facilitated manipulation and organization of registration form and photo content in HBase and Oracle databases by creating media and document management back-end services (Apache Thrift and Jersey REST).

• Modified existing and wrote new functionality for iOS / Android applications to interact with ApplicationXtender document management tool via HTTP.
• Crafted key frameworks and implementations for features such as connection pooling, REST unit testing and caching.

• Devised and constructed functional / integration test framework using JBehave supporting REST and non-REST services including automated prerequisite retrieval and creation.
• Contributed to rewrite of large number of centralized services to client-local REST services using FHIR-compatible endpoints by strategically leading team of 6 consultants as part of larger consulting initiative working across Cerner.
