I'm Pushpal Roy, a Senior Android Engineer / Android Technical Lead with 10+ years of experience building scalable, high-performance mobile products across banking, fintech, B2B, utilities, and enterprise domains.

I specialize in:

• Android native development with Kotlin, Java, Jetpack Compose, and modern Android architecture
• Kotlin Multiplatform and Compose Multiplatform for cross-platform product development
• Backend-integrated mobile systems using Ktor, REST APIs, GraphQL, WebSockets, SQL/SQLite, and SQLDelight
• Reusable architecture, SDUI, offline-first systems, and secure client-server communication
• AI-assisted engineering workflows using tools like Claude Code, Codex, GitHub Copilot, MCP, and project-specific prompt/skill systems

I enjoy turning complex product requirements into elegant, maintainable engineering solutions — and building things that are both technically strong and delightful to use.
