I am a Senior Software & Mobile Engineer with 10+ years of professional experience specializing in Native Android development, backed by robust full-stack capabilities across modern web and enterprise backend architectures.
My core strength lies in my versatility. While my deepest expertise is in architecting high-performance Android applications, I seamlessly bridge the gap across cross-platform teams with intermediate experience in React frontend, Node.js/Express, C# .NET backends, and a foundational knowledge of iOS.
I actively leverage modern workflows to accelerate product delivery. I utilize advanced Prompt Engineering to optimize code quality, automate testing, and streamline documentation. Furthermore, I practice Spec-Driven Development (SDD), transforming technical specifications into precise, AI-assisted implementations to ensure tight alignment between engineering design and business requirements.
Mobile Mastery: Android SDK, Kotlin, Java, Jetpack Compose, iOS foundations Web Frontend: JavaScript, React Backend & API: Node.js, Express.js, C# .NET Databases & Tools: MongoDB, Git, CI/CD, Azure Architecture & Patterns: MVVM, MVI, MVC, Clean Architecture, Spec-Driven Development (SDD)
