● Team leader in charge of all cloud backend services in all environments. Responsible for the full software lifecycle including build, testing, deployment, and monitoring. Led project to prevent downtime by standardizing instances and servers, updating the software stack, and reducing complexity of the software stack. This cut down the amount of downtime as well as greatly reduced the effort needed by DevOps to manage and provision new infrastructure.● Architected, designed, and led a new initiative for real time streaming architecture. By moving the application from a monolithic, stateful, and complex architecture to using technologies like Kafka, Kafka Streams, and Cassandra, I was able to create a microservice platform that will handle company growth in the form of data throughput and features well into the future.● Worked in concert with DevOps to create a continuous deployment and integration framework for the cloud backend applications, reducing deployment time and mostly eliminating manual intervention. This collaborative work led to best practices and greater quality due to removing the chance for manual errors.● Created and documented the standards for the application including root cause analysis. Decoupled the application into different repositories, standardized the use of Maven and unit testing, and documented the workflows which reduced developing time by almost a third and prevented costly production errors.● Developed a new REST API using Spring Boot and Maven. This replaced outdated SOAP APIs and created new functionality enhancing the capabilities of the application.

● Leader in my team to integrate and release a multiyear, first in its class functionality, long seek by customers, involving all the teams in the company. This functionality slashed hundreds of hours of error prone workflows for multiple users.● Owner of the full development cycle of multiple projects. From the initial problem, to the design, development, testing, and release of the final product in VB6, HTML, CSS, XML, XSL, and Cache/Mumps.● Team leader that regained the trust of international customers by deploying in a very short period of time a set of products that covered most of their needs after years of failed attempts by my team. These customers later praised our effort and products in a companywide customer meeting.● Eliminated inconsistencies and improved the selection of the provider in a hospital encounter. This consolidated many different applications’ workflows by providing an API, easing maintenance and support.● Mentor of multiple new employees, integrating them in the team and teaching them the company processes to make them successful developers in the team. Considered most valuable player in the team in 2013.● Leader of the reporting functionality in two teams. Increased the satisfaction, by offering multiple useful reports, to customers by listening to their needs. Removed the need of creating duplicate Crystal reports by creating User Defined Functions (UDF) in both Oracle and Microsoft SQL. ● Pioneer creating my team’s first Universe (SAP product) allowing non-technical end-users the ability to create their own analytical reports on the fly without the knowledge of the data model.

● Helped with the transitioning of one product management software to a new one.● Assisted employees with network and computer issues.● Implemented a system to automate the manual transition from one system to the new one. This helped save countless hours of manual and repetitive process as each product needed to be transitioned manually.
