Continued to expand the functionality of the Java REST service I had been working on as a Junior engineer, but with more of a leadership role. By now the domain expert on the team and "go-to person" across the org for related topics, with the deepest knowledge of the data model, I frequently mentored interns and junior engineers, and worked with leadership to shape the roadmap in a way that created for the largest customer benefit. I decreased response times on a selection of key, underperforming API's by as much as 95% through code refactor, tweaking DB schema, and adding targeted indexes, with all changes done online with immediate roll-back available. Helped migrate the service to AWS using Kubernetes, including planning and implementing a migration strategy for moving DB LOB storage to S3 and implementing a more robust encryption procedure with regular key rotation. I also was deeply involved in the legacy monolithic application that the service was decomposing (Java/SQL Server/EclipseLink). With almost non-existent documentation and large amounts of dead or orphaned code, I frequently had to reverse-engineer and analyze prod data to determine the actual behavior, developing strong SQL querying skills in the process. This led to me frequently building ah-hoc (and sometimes complex) SQL queries for business partners to answer questions and fulfill critical requests. Continued a heavy focus on production support, moving from NewRelic to AppDynamics, and adding container resource management and tuning to the mix.

Scaled and built out a REST-based Java web service that provided business-critical work-flows, with high availability and wildly variable load. Quickly moved from a junior role to taking on heavier tasks, such as designing new endpoints/workflows, creating data model changes and online migration scripts, while expanding knowledge of a highly complex domain (US payroll taxes). Supported the product end-to-end with monitoring and alerting (Splunk, NewRelic), taking the lead in eliminating alerts that were non-actionable, while fixing root causes of the more frequent ones.

Started my journey from C++ engineer to Java expert and learned what real enterprise software engineering looked like (first exposure to CI/CD, automated test suites, etc). Finished my 'summer internship project' in 3 weeks (password lockout feature for internal web tool - LDAP, Oracle, Java, Apache Flex) and began picking up regular sprint work. Had some fantastic mentors and learned much more than I had imagined I would. Skills: Java
