About

šŸ‘‹ Hey there! I’m a Senior Mobile Developer with over 10 years of experience building high-performance apps that make a real difference—across FinTech, MediaTech, and HealthCare. I specialize in Kotlin, Jetpack Compose, Flutter with Dart, and Kotlin Multiplatform (KMP) to craft seamless cross-platform experiences. My approach is simple: solve real-world problems with clean, scalable code and a deep focus on user experience. šŸš€ What sets me apart? I don’t just build apps—I build products that scale, delight users, and meet strict compliance & security standards (especially critical in banking and healthcare). šŸ’¼ A few highlights: šŸ’³ Built a secure digital payment suite for a leading FinTech startup, now serving 1M+ users with 99.99% uptime šŸ“ŗ Led mobile architecture for a MediaTech app with millions of video plays per day and real-time content updates šŸ„ Created a remote health monitoring app using Flutter & Bluetooth integration—currently used in 200+ clinics šŸ“± Delivered 15+ mobile apps end-to-end, across Android and iOS, with a focus on performance, accessibility, and maintainability 🧠 My mindset: Every bug is a puzzle. Every delay is an opportunity to optimize. I’m a strong believer in clean architecture, modular codebases, and team collaboration to ship great products faster and smarter. Let’s connect if you’re building something impactful—or just want to geek out over Kotlin vs. Dart šŸ˜„
