Analysis, development, and maintenance of functionalities for an ERP and for the operational staff's mobile application.

My role involves developing web components for the ERP frontend, components for the mobile application, and the microservices that feed both; advising the client at all times to help them in decision-making.

The mobile application must also be tolerant to lack of coverage, having a synchronization system between the remote database and the local database.

Analysis, development, and maintenance of small web applications.

Occasionally, I collaborate on software projects for small businesses, from content management sites to software for automating tasks.

In this experience, I am learning to establish early contact with the client to understand their needs and offer them the best solution.

Analysis, development, and maintenance of functionalities for the migration of a service hiring platform, as well as resolving incidents and hotfixes for the old platform.

Regarding the legacy application, **I contributed to code improvement, reducing the average daily production incidents from 20 to less than 1**.

Meanwhile, I collaborated on the migration of this platform to more modern technologies: developing the microservices architecture, the frontend architecture, the development of functionalities, and a plan for both applications to coexist in production, so that users could use the web application without noticing this coexistence. This also allowed for a very simple and reliable rollback system.
