Built and evolved BetterUp's native iOS (SwiftUI) and Android (Jetpack Compose) applications, delivering product initiatives across coaching, leadership, and AI experiences. Partnered with Product, Design, and Engineering teams to improve mobile experiences through experimentation, A/B testing, and behavioral analytics, helping identify user friction and inform product decisions that increased engagement and platform adoption. Established AI-assisted engineering workflows by creating reusable documentation, agent skills, and MCP-based development practices (Xcode, Git, Jira, Atlassian), improving engineering productivity and enabling a small mobile team to deliver complex initiatives more efficiently. Contributed across mobile, backend (Ruby), and web (React/Ember) codebases when needed, reducing cross-team dependencies and enabling faster end-to-end delivery of product initiatives. Evolved the native architecture through SwiftUI, Jetpack Compose, automated testing, and modern engineering practices, improving maintainability, scalability, and long-term development efficiency.

Improved property discovery by redesigning custom map marker rendering for GetYourNest, eliminating performance bottlenecks and delivering a significantly smoother map experience. Built the mobile platform from the ground up for Reibus, enabling a scalable mobile experience that supported the company's digital marketplace growth. Delivered high-security mobile applications aligned with global PCI compliance standards for PCI Security Standards Council, enabling secure mobile workflows for payment security initiatives. Reduced development time across multiple client products by establishing reusable mobile architecture, shared components, and CI/CD pipelines (Fastlane, Bitrise).

Built the official mobile platform for Uruguay's public education system, enabling nationwide digital access for teachers and families through applications with more than 500,000 downloads. Replaced paper-based classroom operations with the first nationwide mobile solution for teachers, enabling real-time attendance, grading, and student management across more than 10,000 educators. Expanded the platform to iOS and Android, connecting schools and families through real-time communication and improving access to school information. Transformed the national enrollment system by implementing a mobile school registration module within the family app, successfully digitizing an infrastructure that previously relied entirely on manual paper forms and in-person queues. Collaborated with backend teams to scale APIs and data infrastructure supporting nationwide adoption and high-volume student data synchronization.

Developed native Android and iOS applications for international clients, contributing to consumer-facing mobile products and strengthening expertise across the Apple and Android ecosystems.

Developed secure, data-sensitive banking and payment systems under strict regulatory compliance, optimizing backend systems to ensure reliable and high-volume financial transaction processing.
