About

I am a Principal Engineer with more than 15 years of experience in software development, specializing in Swift/iOS, mobile platforms, React Native, Go, observability, and full-stack engineering. I am technology-agnostic and choose solutions based on business needs.

I have worked across iOS, Android, React Native, backend services, web applications, databases, CI/CD, and system architecture. My experience includes leading platform initiatives, designing cross-platform solutions, mentoring senior engineers, writing technical RFCs, and improving engineering productivity.

At PicPay I shipped Swift work across the mobile app, created the platform that supports React Native inside a brownfield iOS and Android codebase, and architected a Go service that converts mobile observability signals into OpenTelemetry Protocol, cutting troubleshooting time across the company and enabling a Low-Code platform that lets non-engineers deploy mobile updates without a release.

At Uber I architected and implemented the audio recording feature on iOS (Swift and AVFoundation) and architected the Android side so both platforms were equivalent, used by millions of riders and drivers under peak global load.

Career Highlights

• Built a Go-based service at PicPay that converts mobile observability signals into OpenTelemetry Protocol.
• Created a Low-Code platform enabling non-engineers to deploy mobile updates without waiting for a release.
• Developed a React Native platform adopted across multiple product squads.
• Designed Uber's Safety Media audio recording framework using Swift and AVFoundation.
• Architected equivalent iOS and Android solutions for a safety-critical platform used by millions of riders and drivers.
• Shipped Nubank's Virtual Card feature using XCTest, TDD, and Clean Architecture.
• Delivered mobile, backend, and frontend features using Xamarin, C#, Python, Django, JavaScript, Swift, and Ruby on Rails.

Notable Projects

• PicPay mobile platform and observability initiatives
• PicPay Low-Code mobile deployment platform
• PicPay React Native platform for brownfield iOS and Android applications
• Uber Safety Media audio recording platform
