AI Development Workflow

How I use AI tools like Cursor and GitHub Copilot to build, improve and ship projects faster.

Codebase analysis

I use AI assistants to quickly understand unfamiliar parts of the codebase, trace data flow, and spot edge cases that are easy to miss in manual reviews.

Implementing new features

For new features, I pair program with AI to sketch components, API calls and state management, then refine the implementation to match the product vision and code style.

Refactoring components

AI helps me refactor large components into smaller, reusable pieces, improve naming, and modernize patterns while keeping behavior and UI consistent.

Developer productivity

By automating boilerplate, tests and repetitive changes, AI tools free up time to focus on architecture, performance, UX and solving the actual product problems.
