I am part of the product engineering team that implements features in the backend application for the Sphere product.
I also work as part of the core engineering team, which works with core software that provides data to all the other applications.

Currently, i am working on updating the application to adapt to a container based infrastructure as well as updating the applications from java 8 to java 21

• Migrate hard-to-maintain legacy application to Spring Boot microservices. Reducing the downtime in case of failure almost to zero. Released these applications without any downtime.
• Responsible for creating a web application for the customer service team to configure the core gateway application. Allowing them to be independent when handling external clients’ requests. This reduced the response time from days to seconds as well as the cost of 4 heads per change to just 1.
• Upgrade and containerize Java applications to the latest Java 17+. Expose REST APIs to abstract away internal as well as external resources.
• Research and develop proof-of-concept applications to test market needs.
• Additional work with applications in Python, Elixir, and DevOps tools like Ansible playbooks and Jenkins pipelines.
• Wrote extensive documentation on internal architecture.

• Use Test Driven Development to develop the core application. Focusing primarily on code quality and readability.
• Refactored legacy applications to Java 8+. Architected various integration services, adding more complex features such as tools for importing data or synchronization of files between the web application and a desktop app.
• Worked in a team of two to develop a reporting module for the BI team, allowing them to generate custom reports for each client.
• Maintenance work to release and upgrade the core system.
