Client feedback

Evidence from delivered work.

“I hired Alexis to audit a mobile app that I had hired someone else to develop originally. I also had Alexis help me get the app published on the app stores.”

About

Eleven years of building, publishing and maintaining apps.

I started developing professionally in 2015. Since then, I have worked both as an independent product creator and as a developer for clients worldwide.

That combination matters. I understand the code, but also releases, store policies, user feedback, monetization and the operational work required after launch.

Common questions

What clients usually need to know.

Do you only develop mobile apps?

Mobile development is my specialty, especially Flutter, iOS and Android. I also build the web applications, APIs and backend systems a complete product requires.

Can you take over an unfinished or outdated app?

Yes. I can audit the codebase, identify the highest-risk issues and propose a practical rescue plan before committing to a larger development scope.

Can you handle App Store and Google Play delivery?

Yes. The work can include release builds, real-device QA, TestFlight, store listings, policy requirements, subscriptions and production submission.

How do we start a project?

Send the product, current state, required platforms, timeline and approximate budget through the project brief. I will review it and recommend the next practical step.
