What I do

Mobile apps

Native mobile apps for Android and iOS that stay reliable under real-device limits.

In plain words

Apps for Android phones and iPhones, built natively so they feel right on each. I pay particular attention to the things that go wrong in real life, like a weak connection, a battery saver, or an older phone.

What this involves

I build native mobile apps for Android and iOS. On Android I write Kotlin and Jetpack Compose; on iOS, Swift with SwiftUI and UIKit. The parts I care about are the ones that break on real phones: offline data, background work, notifications under battery limits and performance on low-memory devices.

Questions people ask

›Do I need to understand the technology?

No. I explain things in plain language and will stop and explain again if something is not clear.

›Can we work together if I am in another country?

Yes. I work with clients anywhere, remotely, by message, email and video call, and I am comfortable working across time zones.

›What happens in the free consultation?

You tell me what you want to achieve, you ask your questions, and I tell you honestly what I think and what the next step could be. There is no obligation.

›Can you work on something that already exists?

Yes. I can fix, speed up or take over a website or app that someone else built. We would start by looking at what you have.
