Senior Mobile Engineer
Building apps
people love.
From native iOS applications to cross-platform products, I build secure, scalable, and user-focused mobile experiences that people enjoy using.
Building mobile products with engineering excellence
Technologies, frameworks, and engineering practices I've used to build scalable mobile products across iOS, Android, Flutter, streaming, security, and fintech.
I build mobile products that scale, perform, and last.
I enjoy solving the kinds of mobile engineering challenges that users never notice—because everything just works. Whether it's reducing video startup times, building secure VPN tunnels, or designing architectures teams can maintain for years, I focus on creating reliable products that scale.
Outside of building products, I'm passionate about clean architecture, mentoring developers, and solving complex engineering challenges.

Complex engineering problems I solve
Media Streaming
Production Video Platforms
Designed and delivered premium video streaming applications supporting live and on-demand content with a strong focus on playback performance, content protection, and exceptional viewing experiences.
Playback Optimization
Engineered high-performance AVPlayer pipelines with adaptive bitrate streaming (HLS), offline downloads, Picture in Picture, AirPlay, Chromecast support, subtitles, and optimized buffering for seamless playback.
DRM & Content Protection
Implemented FairPlay Streaming (FPS) with secure license server integration, encrypted media delivery, certificate management, and protected playback for premium content distribution.
Streaming Infrastructure
Built scalable streaming experiences supporting Live TV, Video-on-Demand, playback analytics, and real-time monitoring using Firebase, Mux, and Conviva to improve quality of experience.
Performance Engineering
Optimized startup latency, memory consumption, buffering behavior, and rendering performance using Instruments and AVFoundation best practices to deliver responsive playback across iPhone and iPad.
Security & Enterprise Networking
Enterprise Security Solutions
Designed and delivered secure networking infrastructure for enterprise, fintech, and VPN applications with a focus on encrypted communication, strong authentication, and production-grade security.
VPN & Network Infrastructure
Built enterprise VPN solutions using WireGuard and Apple's Network Extension framework, implementing custom tunnel configuration, secure routing, connection lifecycle management, kill switch support, and reliable background connectivity.
Authentication & Cryptography
Implemented certificate-based authentication using PKI and client certificates (.p12), OAuth/JWT authentication, TLS 1.3, certificate pinning, biometric authentication (Face ID/Touch ID), and secure credential storage with Keychain.
Secure Communication
Developed secure networking layers with URLSession and Alamofire, supporting encrypted REST APIs, automatic token refresh, ATS compliance, custom URLSession delegates, resilient session management, and background networking.
Enterprise Security Practices
Applied OWASP Mobile Security recommendations, secure data storage, jailbreak detection awareness, defensive coding techniques, and end-to-end encryption practices to protect sensitive user and enterprise data.
Architecture & Scalability
Building Scalable Mobile Systems
Designed and evolved scalable mobile architectures that improve maintainability, accelerate feature delivery, and support long-term product growth across enterprise and consumer applications.
Architecture Design
Architected production applications using MVVM, VIPER, Coordinator, Clean Architecture, and Repository patterns, creating modular, testable, and maintainable codebases that support long-term scalability.
Reusable Foundations
Built reusable networking layers, shared UI components, dependency injection, and common utilities that reduced development effort, improved consistency, and accelerated feature delivery across multiple projects.
Engineering Leadership
Introduced modern architectural patterns, established coding standards, conducted code reviews, mentored developers, and promoted SOLID principles to improve code quality and team productivity.
Scalable Product Evolution
Designed systems that adapt to changing business requirements, enabling teams to safely extend applications, introduce new features, and refactor with confidence while maintaining production stability.
Performance Engineering
Building Fast & Reliable Mobile Experiences
Optimized production mobile applications for speed, responsiveness, and stability by improving startup performance, memory efficiency, rendering, networking, and media playback across enterprise and consumer products.
Performance Optimization
Improved application startup time, UI responsiveness, scrolling performance, and rendering efficiency through profiling, code optimization, efficient state management, and asynchronous processing.
Memory & Resource Management
Optimized memory allocation, eliminated memory leaks, managed background tasks, and improved resource utilization using Instruments, Memory Graph, and performance profiling to ensure stable long-running applications.
