Tantan

Objective-C iOS

Tantan is currently the largest dating app in China, with over a hundred million registered users. As a founding team member, I had the great opportunity to work on the iOS app from scratch, thereby witnessing the scaling from zero users all the way to millions of people using the app on a daily basis. Most of my work consisted around the UI; building various views and animations, and making sure that everything runs smoothly on device. I was also in charge of a cooperation together with Qualcomm, where the iOS and Android clients integrated Qualcomm’s upcoming LTE-Direct technology to enable direct device-to-device communication. On the 23rd of Februray 2018, it was announced that Momo, the Chinese location-based social networking app, aquired Tantan for around $735 million.

Sthlm Travel

Swift iOS watchOS

Sthlm Travel is the fastest and most convenient way to get realtime and trip information about the public transport in Stockholm (SL). I started this project together a friend in late 2014, and it was my first introduction to Swift and to watchOS. The app was first released in March 2015, which at the time was one of the first Apple Watch apps released on the Swedish App Store. Throughout the years, the app has been featured under many categories and collections on the Nordic App Stores.

P1

Objective-C iOS

P1 is a photo sharing app for urban trendsetters sharing their love for style, fashion, and unique lifestyles. I was part of a small (two person) team which built the app from scratch, where most of my responsibilities revolved around the user interface. Various pictures feeds, grids, and animations were built by me. Being my first larger app, it taught me a lot about building a maintainable and scalable application.

SMS Park

Swift iOS

With SMS Park, you’re able to quickly pay for your parking - anywhere in Sweden. I had the pleasure to be involved in this project a few years ago, when they were just getting started. Working together with a team very of tech savvy and passionate people, I was given a lot of freedom to further develop and (to some extent) design their iOS app.

Cryptoverter

Swift iOS

The fastest and most convenient way to convert between crypto and fiat currencies, designed and developed by me. The app contains over 1500 cryptocurrencies and over 30 fiat currencies. The main difference to other similar apps, besides from the UI, is that Cryptoverter supports conversion between crypto and crypto, crypto and fiat, and of course fiat and fiat.

Squares

Objective-C Swift iOS

Squares is a simple game which challenges your eyes and your reaction time. This was my first iOS game, initially built in late 2014. Most of it is written in Objective-C, but a few parts are written in Swift. The app is mostly popular in China, and has reached a high ranking on the Chinese App Store a few times.

Skötrumskartan

Swift iOS

A simple app made for finding restaurants that have baby changing tables in Stockholm. Created for a group of friends, who saw the need for it, and had gathered all the data themselves. The app has been featured in a few magazines in Stockholm, and hopefully it can expand to a few other Swedish cities in the future.

The Pepper Club

Objective-C iOS

My at the time employer was given the responsibility over a campaign led by Dr Pepper Sweden. A code was placed under the caps of Dr Pepper bottles, for people to enter in their app to accumulate points. Points could either buy merchandise, or be saved, for the chance of winning a grand prize (if you held the most points). As a Dr Pepper lover myself, it was a great honor building their iOS app.

Open Source

Proxy Switcher

Theos iOS Jailbreak

ProxySwitcher is a tool for jailbroken devices that lets you easily toggle a WiFi-proxy on and off. Tired of having to manually enter proxy credentials for every new WiFi-network, I built this to make my day to day mobile usage easier. Building this gave me some insight to how a few private API:s work, as well as how to build and communicate with a daemon in the iOS system. ProxySwitcher has been written about in two different articles, from the Jailbreak news reporting sites Redmondpie and iDownloadBlog.

WeChat Envelope

Theos iOS Jailbreak

WeChatEnvelope is a simple, UI based tweak to open red envelopes inside of WeChat. Made for fun and for research purposes, it also serves as a proof-of-concept how simple it is to create touch based tweaks to manipulate apps or games to one’s advantage. While my tweak directly calls code within the app, this could easily be replaced by simulation of touches to further prevent detection.

Facebook Image Picker

Swift iOS FBSDK Cocoapods

A simple and lightweight Swift library for choosing an image from Facebook. With minimal and straightforward code, it can either be used out-of-the-box, or serve as a great stepping stone to build something with more functionality.

Language Switcher

Swift iOS

A sample Swift project on how to handle internal localization switching. Contains a helper class I built to easily add and switch between languages, as well as accessing localized content within the app.
