For a new app, that means identifying the core features and planning development around your priorities. For an existing product, it means reviewing the codebase and dependencies before making changes. Throughout development, I focus on clear communication, practical technical decisions, and code your team can maintain and extend. Have an app idea, Figma designs, or an existing application that needs improvement? Send me a brief overview of your project and what you want to achieve, and we can discuss the next steps.
