Experience
API for a Soccer Score Prediction Game
https://github.com/facup94/wc-2022-predictorAs the main back-end developer, I designed and implemented the back end application, which included defining the technology stack and storage system, planning the high-level architecture of the API, and implementing the endpoints used by the mobile application for the game user interface. I collaborated with the Android developer to integrate both parts of the app and the product designer to refine and estimate his requirements.
Slack Bot for On-call Schedule Members
I designed and implemented the API that receives notifications from Opsgenie and uses the Slack API to send messages to the person in charge of resolving the incident. I did this after reading and learning from the Slack API and Opsgenie documentation pages. I also collaborated with the DevOps team to define and polish their requirements.
