As a dedicated back-end software engineer, I actively contributed to the development of a transformative healthcare platform aimed at enhancing consumer access and experiences, ultimately striving to improve health outcomes while minimizing overall costs. In this pivotal role, I was responsible for the following: • Complete back-end development cycle of micro-service web application components, ensuring seamless integration with cloud technologies such as Microsoft Azure. • Collaborating on documentation, promoting clarity and a shared understanding of the project's goals and requirements among team members. • Applying my technical expertise and passion for innovation to make a meaningful impact on individuals' health and well-being. Technologies used: Java 11, Spring Web-flux, Spring Cloud, Gradle, Microsoft Azure Services (AKS, EventHub, CosmosDB...)

As a key senior team member, I was actively involved in a high-priority project centered on enhancing customer service for our company. The project's primary objectives included optimizing resources, minimizing operational costs, and elevating client satisfaction levels. In my capacity, I was responsible for a variety of tasks, such as: • Developing innovative and well-tested features for both back-end and front-end components of a business-critical web application used by the country's largest telecommunications company. • Maintaining, refactoring, and augmenting test coverage of existing code to ensure continued efficiency and reliability. • Conducting code reviews and coordinating code merging, release, and deployment of project deliverables. • Collaborating closely with business stakeholders and product owners to design and refine feature requirements, providing expert advice and insights on effective implementation strategies.

As a versatile full stack developer, I played a crucial role in creating, maintaining, and upgrading a diverse array of web applications, websites, financial reports, and portals catering to both internal and external clients. Key accomplishments include: • Successfully migrating numerous applications running on JBoss and Apache TomEE application servers to Tomcat, as part of a strategic cloud migration initiative. • Overcoming the challenges of mitigating and addressing security vulnerabilities while transitioning applications, with a focus on meeting stringent security standards for financial data handling before deployment to production. • Key applications migrated encompass Mi Perfil (a credential reset tool for user access), Billing Web Portal (a billing and reporting platform), Payroll Manager (an employee financial records reporting generator), Web Link Proxy (a B2B credit information service), Application Manager, DC Web Portal, and Jobs Manager.

As a software engineer on the infrastructure team, I was responsible for building and maintaining an internal search platform that enabled applications to have efficient search capabilities. My role involved developing web services and back-end processes that supported and extended the search engine used by other teams. I was committed to ensuring that the search platform was reliable and performed at a high level for all users. Key accomplishments include: • Implementing a multi-threading solution with Apache Solr, a search platform to store information, which reduced the time required to load large volumes of data from 24 hours to 2 hours. • Lowering document management and archiving costs by implementing RESTful Web Services to store and retrieve electronic documents and images of paper-based information. • Enhancing user experience and usability of the search platform by implementing auto- suggestions and spell-checking features.

I had the opportunity to work on the development team at Bonanza, an auto repair shop specializing in the automotive market, including tires and lubricants. Our team was responsible for building and improving internal systems for accounting, human resources, and payroll. As a software engineer, my specific role involved upgrading these systems to Java web technologies and programming the web integration of an e-commerce site. This challenging and rewarding project allowed me to contribute to the success of the company by enhancing their internal systems.
