Selected Work
Cross-platform mobile work at scale
Two examples from Citi Mobile Rewards showing how I combine hands-on engineering with delivery and reliability.
Citi Mobile Rewards
Deliver Android and iOS rewards features for 14M+ monthly users
Dual-platform ownership
Scope
API-driven features within the Rewards workstream, including Benefits dashboards, personalized flows, feature-flagged releases, analytics, and accessible UI.
What I do
- Own production Kotlin and Swift implementation.
- Guide design, code reviews, testing, and release readiness.
- Coordinate backend, QA, product, design, and analytics partners.
- Support releases and production follow-through.
Engineering pattern
Use REST APIs, MVVM, reusable components, and feature flags to keep implementation consistent across mature mobile codebases.
Mobile Modernization & Reliability
Improve code quality without slowing product delivery
Quality + Reliability
Challenge
Modernize mature Android and iOS code while protecting release quality for a high-traffic consumer app.
What I changed
- Converted Java code to Kotlin and cleaned up legacy paths.
- Advanced MVVM and API migrations with reusable components.
- Expanded JUnit, MockK, and XCTest coverage.
Reliability
Resolve crashes and UAT defects, take ownership of late-stage issues, and coordinate emergency changes, testing, and approval when a release is at risk.
How I Operate
Hands-on leadership from implementation through production
Launches
Connect design, implementation, testing, release readiness, and production support across both platforms.
Reliability
Use test coverage, crash investigation, incident response, and disciplined change coordination to reduce release risk.
Engineering Leverage
Use reusable components, feature flags, automation, and reviewed agentic coding to reduce repeat work.
Team Influence
Guide design and code reviews, mentor engineers moving into native mobile work, and interview candidates.
