At Zup IT, on the Porto Seguro project, I improved Pix PF features and built Claude skills for test generation and code review. The test-generation skill raised coverage from about 30% to about 100% for unit-testable code, reduced test creation to around 10 minutes per feature, and surfaced four production-code bugs.
At PicPay, I led iOS development of high-traffic financial features for 200K+ users, including BACEN-regulated PixBet flows. I used Instruments to find and fix a retain cycle behind unbounded memory growth, then verified a stable heap.
At Bornlogic, I cut build time from eight minutes to two by modularizing the app, and built a VIPER scene generator that reduced scene setup from over an hour to about 10 seconds. I also architected a media feed with background downloads and offline caching, and created ComposableKit, an open-source Swift macro library for SwiftUI apps.
