Experience
Here is a quick summary of my most recent experiences:

- Configured third-party services, such as, Fastlane, Firebase, Sentry, AWS, as well as Google Play Store and Apple Store Connect.
- Configured Github Actions to run CI/CD, in both, mobile and api repositories to run, tests and deployments.
- Led product A/B testing, analyzing user's feedback and needs and transforming them into a backlog of, features, bugs and wishes to clarify roadmap and give users top-notch features quicker.
- Improved team working peace by identifying bottle-necks in sprints, such as blocking tasks (i.e: UI missing), resulting in 20% faster working peace on the following months.
