Mobile Development Chief at LOi
As Head of Mobile Development at LOi, I led the mobile engineering division while serving as a principal contributor on the React Native codebase. Defined the architectural patterns, integration strategies, and performance optimization standards for the company's cross-platform mobile applications. Conducted continuous technical research to identify and evaluate emerging mobile technologies, frameworks, and platform-specific capabilities for production adoption.
Duties & Responsibilities
Core duties held during this position.
- Architect reusable component libraries and shared packages — define API contracts, versioning strategies, tree-shaking compatibility, and cross-project dependency management
- Ship user-facing features end-to-end — from component architecture and state management (React, Redux, Zustand) through API integration to production deployment and monitoring
- Solve complex UX problems through systematic decomposition — reduce cognitive load, eliminate unnecessary states, and design progressive disclosure patterns for power users
- Architect and ship native mobile applications (iOS/Android) — define navigation patterns, offline-first strategies, push notification systems, and app store optimization
- Coordinate cross-functional feature delivery — align engineering, design, QA, and product on scope, technical approach, and acceptance criteria from discovery through release
- Lead mobile engineering teams — define native/hybrid architecture decisions (React Native, Swift, Kotlin), establish release cadences, and drive platform-specific quality standards
- Identify technology inflection points — evaluate AI breakthroughs, platform shifts, and user behavior changes that create strategic opportunities or existential risks
- Integrate third-party APIs and external data sources — design resilient integration layers with retry logic, circuit breakers, rate limit handling, and response caching
- Triage and resolve production defects — prioritize by user impact and blast radius, implement fixes with regression tests, and conduct post-mortems on critical incidents
- Evaluate and adopt emerging technologies — AI/ML frameworks, new runtime environments, build tools, and developer productivity platforms through structured PoC processes
Key Contributions & Achievements
Initiatives I personally led, co-led, or was directly accountable for.
- Engineered the LOi mobile application from the ground up using React Native, implementing a shared codebase architecture for iOS and Android with native module bridging where performance-critical
- Achieved top-3 ranking in the App Store's most downloaded category for three consecutive weeks post-launch, demonstrating market-product fit validation
- Achieved top-3 ranking in Google Play's most downloaded category for three consecutive weeks, confirming cross-platform market traction
- Orchestrated the end-to-end publication and distribution pipeline across Apple App Store, Google Play Store, and ancillary marketplaces
- Developed a purpose-built Huawei AppGallery InstaApp variant, adapting the platform to Huawei Mobile Services (HMS) ecosystem constraints and APIs
