👋 Hi, I'm D&J — an Android Developer focused on Kotlin, Jetpack Compose, and mobile architecture, with hands-on experience in Web3 products and a growing interest in AI-powered engineering workflows.

I enjoy building apps that are not only functional, but also clean, scalable, and maintainable.
Beyond shipping features, I care deeply about architecture design, engineering efficiency, code quality, and long-term product evolution.

• Mobile Development
  Android, Kotlin, Jetpack Compose, KMP, and building apps that scale well in real-world products.

• Architecture & Engineering
  Multi-module design, Gradle optimization, state management, maintainable codebases, and practical engineering improvements.

• Web3
  Wallets, on-chain interactions, asset-related features, and the intersection of mobile products and decentralized ecosystems.

• AI Engineering
  Agent workflows, MCP, RAG, and exploring how AI can improve real development productivity.
