About

I am a hands-on Mobile Engineering Leader with 11+ years of overall experience, including 8+ years building secure, scalable mobile products and 3+ years leading engineering teams. My background spans the full mobile engineering journey from building native iOS applications from scratch to designing modular architectures, SDKs, secure networking, CI/CD systems and reliable mobile platforms used by millions. I have also scaled an iOS team from 1 to 20+ engineers while remaining involved in architecture, technical reviews, production reliability, and critical engineering decisions. At Snabbit, I work across Flutter architecture, performance, security and release engineering. I reduced application launch time by 50%, built multi-platform CI/CD workflows and implemented mobile security controls including App Attest, Play Integrity, Firebase App Check and SSL pinning. As a Mobile Platform Engineer, I built a reusable AI document processing platform using Apple Vision, Core ML, TensorFlow Lite and LLM APIs. The platform supports document scanning, QR recognition, OCR, on device inference, offline workflows and backend assisted verification reducing processing latency by 30%. I also designed an AI Workspace for iOS using SwiftUI, MVVM, Clean Architecture and async/await with an extensible architecture for OpenAI, Gemini and Claude integrations. At slice, I helped build and scale the iOS platform and engineering organization. Outcomes: • Improved application stability from 85% to 99% through crash analysis and error handling redesign. • Reduced release time from 250 to 60 minutes and manual effort by 70% through automation. • Reduced build times by 40% across Jenkins, Bitrise and GitHub Actions. • Led the evolution from MVC to VIPER/MVVM and developed reusable SDK ready components. • Mentored senior engineers and helped scale the iOS organization to 20+ engineers. Strengths: • Engineering management, mentoring and technical strategy. HLD, LLD and TRD review. • Native iOS development with Swift, SwiftUI, UIKit and Combine. • Flutter, mobile platform architecture and modular SDK development. • AI/ML integration with Apple Vision, Core ML, TensorFlow Lite and LLM APIs. • Fintech, secured mobile systems, performance, reliability, CI/CD and release engineering. • Architecture and cross functional execution for high scale fintech products. I am interested in Engineering Manager and Staff Mobile Engineer opportunities where I can combine hands-on technical depth with team leadership and platform level impact.
