• Referent for system modules and projects: Take ownership of modules developed by me or colleagues from Italy. This involves providing support to coworkers in the country and making decisions on enhancements.• Technical analysis (TA) per analyst business requirements: Analyze the current codebase and create a document, that explains at a technical level, the changes to be made, the new feature to implement according to the Business Analyst (BA) or the required fix. This is created so the developer, that takes in charge the ticket understands what needs to be made and the lead understands what's going to be implemented/changed.• Optimizations for data processes: Reduce the time for API calls made by the client and internal processes. So, the current task returns a faster response and can be improved upon. Made by analyzing the flow and implementing refactors.• Integration of external providers: Be asked to integrate external services like payment gateways, physical cards services or credit score providers. This was done by reviewing all the available documentation on the desired service and work with the provided information or tests made to their testing APIs.• Development of new features: Implement a new feature that could be an improvement or something new.• Migrations: Migrate processes from old systems to something new, so the backend could be more optimal, maintainable and understandable by other developers with a look to the future. A refactor of endpoints, DB connection, logs, reports and the required logic has been made.• Resolution of problems in production: Analyze the error by checking logs and the response returned to the client. Also, the process that occasioned it, so it can be replicated on testing environments. After that create a TA and start working on the solution.
