As part of the Apple Developer Academy, an initiative by Apple that fosters innovation and creativity in app development, I have direct access to workshops, conversations, and testing sessions with Apple engineers and designers. Founded my own indie Development Studio called B-yond Studio with a designer. Tixer: Led the development team to create a powerful iOS app that revolutionizes time zone management and facilitates scheduling calls, meetings, or coordinating with friends and colleagues across different time zones. Coordinated agile development methodology and code reviews. Developed with SwiftUI, Holidays API, and Apple's TimeZones API. Available on the AppStore with over 100 downloads.Memora: Created an iOS flashcard app to enhance learning and features shuffling cards through interactive widgets. Designed using Figma and built with SwiftUI. Available on the AppStore with over 350 downloads and 26k appstore impressions.Keepi: Led the development team to create an expense tracker focused on mindfulness and financial self-discovery. Coordinated the backend implementation with Firestore and Firebase Auth. Available on the AppStore with over 70 downloads.JugglingFruits: Developed a juggling game using SpriteKit/SwiftUI. Available on the AppStore with over 100 downloads and promoted with Meta ads (also working with in-game ads through AdMob, in-app purchases, and Game Center leaderboards).• Mazí App: Event management and networking tool to enhance presenters' audience engagement.Already adopted by PUCPR University with more than 200 concurrent users and in community events such as GDG and CocoaHeads. Currently available at www.maziapp.io.

• I led the development of 15+ custom, reusable components for Domino’s new app, used by over 10 million daily users while ensuring 95% test coverage across unit and UI tests. By streamlining processes, our team reduced the project timeline by 50% in the first quarter, accelerating delivery significantly. Collaborating closely with designers and the Android team, we ensured consistent design standards across platforms, meeting Domino’s rigorous performance and usability criteria.

• As a Data Engineer at MUTANT, I independently developed 8 end-to-end data pipelines using Airflow and Spark to leverage different companies' data analyzing business intelligence. The system handled daily traffic between 20TB and 80TB of data, coming from emails, telephone bots, messaging bots and passing through GCP cloudstore, all the way to Big Query for data dashboards. Helped in the migration of the pipelines from Databricks and Azure to GCP and it reduced operational costs up to $1,700 per day. I also created a generic reprocessing pipeline in Python and Pandas, streamlining repetitive tasks. The migration to GCP, which used Terraform for infrastructure and IAM for security, ensured no service interruptions.

• SERASAI played a key role in a major project to migrate data from an on-premise environment to a new architecture in the AWS Cloud. My responsibilities included data preparation, validation, and treatment, using tools like Kafka, Airflow, Rundeck, and Jenkins. Through my expertise with these tools, I was able to ensure a smooth and successful transition to the new architecture

• Learned the principal processes: turning, drilling, and milling. And other operations like turning, drilling, and milling.
