Professional work experience
Swish, 8.5M users - Currently crafting
I have been working on the Swish android app since August 2023. Swish is the Swedish mobile payment app that enables instant money transfers between users and businesses using phone numbers. It’s widely used for quick, cashless payments across Sweden.
Projects I have worked on
Payment cards: Creating an in-app wallet, so users can use Swish to add their debit/credit card and pay via NFC .
Automatic payments: Swish can be used now as a payment option at merchant sites to handle and keep track of your automatic payments (eg subscriptions).
Scan and Swish: Swish can now be used to scan items at stores, review your shopping list and pay from the app.
My tasks in these projects
Developing critical parts of the features: polling mechanism, parser, error handling, UI (I have worked with MVVM, MVI and MVP). I worked in all the architectural layers.
Technologies used: Kotlin, Kotlin coroutines, Jetpack Compose, XML, Ktor, Dagger Hilt, Lottie, JUnit, mockK and many more.
Creating a deep understanding about the backend services.
Staying on top of dependencies and blockers while actively contributing to the development of a strategic approach to implement features efficiently.
Proactively becoming the go-to person to know about project status within my team during the months close to the public release.
Being actively involved in meetings with stakeholders.
Presenting live demos to stakeholders to showcase features' current progress.
Proactively leading the internal collaboration within the team to create tools to test features




Swish Business, 300k users - Currently crafting
I have been working on the Swish Business app since August 2023. Swish Business is a mobile app merchants can use to charge customers with Swish.
My work at the Swish Business app:
Troubleshooting bugs
Implementing code changes to keep consistency in between both the Swish app and the Swish Business app
Helping out with code reviews, testing and the whole application release lifecycle.
Technologies used: Same as in the Swish app (Kotlin, Kotlin coroutines, Jetpack Compose, XML, Ktor, Dagger Hilt, Lottie, JUnit, mockK and many more.)
