Lead Android Engineer | Kotlin Multiplatform (KMP) Architect | System Design & Performance | Global Remote | 10+ Years Experience

About

I am a Lead Android & Multiplatform Engineer with over 10 years of experience architecting and delivering high-performance mobile ecosystems. My focus is on technical leadership - acting as a force multiplier for engineering teams through system design, architecture ownership, and developer tooling. Currently, as a Lead Engineer at KPN Farm Fresh (Savo), I architected a unified application framework using Jetpack Compose Multiplatform and KMP to manage 3 global brands from a single shared codebase. I also engineered a custom Internal Device Inspector to optimize the developer experience and reduce QA cycles. Core Technical Achievements & Impact: System Integrity: Spearheaded an "Offline-First" transformation at Carnot Technologies, increasing data integrity from 60% to 98% and driving a 95% increase in business growth. Global Reach: Led the "Hills to Home" international rollout for Colgate-Palmolive across Thailand, Vietnam, and Mexico, collaborating directly with Global Engineering Directors. Architecture at Scale: Expert in transforming complex legacy stacks into modern, modular systems (MVI/MVVM/KMP) that support cross-functional pod delivery. Developer Infrastructure: Passionate about building internal tools (like Inspector suites and Design Systems) that empower teams to ship faster and with higher confidence. Specialized Expertises: - Kotlin Multiplatform (KMP) & Compose Multiplatform - Advanced System Design & Modularization - Offline-First Strategy & Data Synchronization - Technical Mentorship & Open Source Contribution I am passionate about building "Infrastructure, not just features" - tools and architectures that empower teams and scale businesses. I'm currently looking for Principal or Staff-level opportunities with globally-minded organizations or forward-thinking remote teams. ✉️ Feel free to reach out for technical discussions on KMP, Architecture, or System Design.
