Mobile Developer | iOS/Swift Engineer | Backend Contributor
I'm an experienced Mobile Developer currently focused on iOS/Swift engineering at Busbud. I specialize in architecting robust and scalable applications and have a strong history of working across the full stackβfrom building native mobile apps (iOS & Android) to contributing to backend services (Ktor, Rust, Elixir).
I am passionate about the intersection of clean code, elegant user experience, and data-driven decision making to align development work with broader business objectives.
These highlights demonstrate the high-impact work I've delivered in previous roles:
- Payment Architecture & Integration: Successfully architected and implemented secure payment flows by integrating new payment providers and deeply utilizing third-party APIs for Busbud.
- Mobile Gateway & Backend: Contributed to the app gateway (built with Ktor using Kotlin) at Epidemic Sound, building new endpoints and integrating mobile apps with other internal services.
- System Rewrites & Architecture: Individually engineered and implemented the entire iOS app architecture for a new native application, successfully replacing a legacy React Native app and ensuring feature parity.
- Cross-Functional Platform Improvement: Enhanced the developer experience at Pipefy by implementing core changes to both the backend (Rust, Elixir, and Ruby) and client-side applications (Swift and Kotlin).
- Mentorship & Feature Ownership: As a Senior Developer, I served as a feature architect, overseeing the full lifecycle from design to deployment, and mentored junior developers through pair and mob programming.
- Quality & Monitoring: Proactively improved app stability by filtering out irrelevant errors in monitoring tools like Sentry to improve the signal-to-noise ratio, allowing teams to focus on critical issues.
