About me
I am a full stack developer building web and mobile apps for startups and business owners. I work mainly in React, Flutter, and Python, taking projects from a rough idea through to something people can actually use. Clients usually come to me needing an MVP built fast or an existing app fixed and stabilized. I write code I am willing to hand off to another developer later, and I tell clients early if a timeline or scope isn't realistic. Past work onboarding flows, payment integration, cleaning up slow database queries.

After fixing the logout issue, Casey went through the rest of the authentication flow to make sure nothing else is missed. Every thing now works as it should and feel much more confident about the app
