🚀 About Me

I'm a Senior Android Engineer with 10+ years of experience building Android and Kotlin Multiplatform applications across fintech, banking, B2B, utilities, and enterprise products.

I enjoy building products that are not just functional, but scalable, maintainable, high-performance, and pleasant to use. My work spans Android native, Kotlin Multiplatform, Compose Multiplatform, and backend-integrated mobile systems — from architecture and reusable components to performance, security, and developer experience.


🧭 What I Do

  • 📱 Build modern Android apps with Kotlin, Jetpack Compose, and clean architecture
  • 🌍 Create shared experiences across Android, iOS, Web, and Desktop using Kotlin Multiplatform
  • 🧩 Design reusable systems with modularization, offline-first patterns, and server-driven UI
  • 🔐 Work on secure mobile systems with SSL/TLS, certificate pinning, OAuth 2.0, JWT, Android Keystore, and E2EE
  • 🤝 Lead engineers through technical design, code reviews, mentoring, and delivery
  • ⚙️ Improve engineering workflows with CI/CD, automation, and modern developer tooling

🛠 Currently

  • Leading Android development for a US-based financial services product
  • Migrating legacy and WebView-heavy journeys into native Jetpack Compose
  • Building reusable Server-Driven UI components and scalable Android foundations
  • Working across GraphQL, backend integrations, and performance-focused mobile delivery
  • Exploring better AI-assisted engineering workflows with tools like Claude Code, GitHub Copilot, Codex, and Cursor
