Highlights

• During my time with the Standards team at GreatMinds, I worked as a fullstack developer on a project focused on improving the management of educational standards for the content team. My main responsibility was to develop internal tools that allowed for more efficient updating, editing, and viewing of standards. The backend was developed using Node.js, and we handled the operations through AWS Lambdas and a dedicated SDK, which allowed for streamlined communication with internal services. For manual interactions, we built a system using React and Strapi. This work helped streamline the team’s workflows, reducing operational time and improving the quality of the standards management process.
• In the Branch Strategy initiative, I worked on creating a standardized format for commit messages using GitHub Actions and on defining a baseline branching model across our projects. As part of this effort, we adopted a trunk-based main branch standard, unifying how branches were managed in all repositories. These changes were implemented via forks to prevent work from being blocked, which helped streamline our continuous integration and deployment processes and improved the consistency and efficiency of our development workflow.

Highlights

• In this project, as the only developer, I was responsible for the end-to-end development of a tool that connected two different APIs and automatically executed asset control. This involved designing, implementing, and ensuring the proper functioning of the entire system. The solution was implemented using AWS Lambda functions, enabling the process to run efficiently, scalably, and without manual intervention. This automation facilitated data synchronization between systems and improved asset traceability and control.
