About

I build apps.
And tell the story.

I'm Carolane, aka Okeep online. iOS developer, tech entrepreneur and content creator since 2020.

I started coding without an engineering degree, just with the drive to build things. Today I ship my own apps, coach other devs, and share everything I learn along the way.

The journey

From beginner dev to tech entrepreneur

The key moments that brought me here.

2020

First steps in iOS dev

I discover Swift and SwiftUI. Instant love for the Apple ecosystem and the feeling of creating something that fits in your hand.

2024

Going online

First tech content on Instagram, TikTok and YouTube. The idea: make tech accessible and show what dev looks like behind the scenes.

2025

Keepio, Caffio, Tanukia

Three native iOS apps back-to-back. Each with its own story, struggles and lessons. The start of the solopreneur ride.

2026

Guides, courses & community

I turn my experience into concrete resources: Claude Code guides, coaching, and building a real iOS dev community.

My beliefs

What I believe in

The principles that guide my work and content.

Ship, don't wait.

Shipping an imperfect app teaches more than ten months of planning. I believe in fast iteration and real feedback.

Tech for everyone.

Dev shouldn't be a closed club. I make accessible what felt blurry when I started.

AI as a copilot.

Claude Code, automations, workflows. AI doesn't replace devs, it accelerates them — if you know how to use it.

Build in public.

I share everything: wins, fails, numbers and struggles. Transparency builds trust.

Guides & courses

I also write iOS guides on KeepOS.

Practical guides for indie iOS devs: Claude Code, App Store publishing, automations. Lifetime updates, no fluff. Available on my learning platform KeepOS.
