Mimo

Introduction

Mimo is an app that lets you learn several programming languages through daily lessons. The teaching methodology is similar to the one used by Duolingo for language learning.

In each lesson, you will respond to questions and do small exercises that you'll have learned how to approach beforehand in a very clear way. And it has a very clean interface that helps you concentrate on learning.

Mimo is an excellent tool to learn all sorts of programming languages no matter how much you already know. A terrific way to study at your own pace and from any location.

Mimo had more than 10 millions downloads.

My missions

I was working as an Android developer with a team of three. When I arrived at Mimo, there was no app on Android so we had to develop it from scratch. We started by designing the architecture of the app and developing the most important feature like the in-app subscriptions, the authentication and the lesson view with all the different types of interactions.

Then, we were working on new features that add more value to the learning of the user. We closely worked with product owners and designers to create the best product and give the users the best user experience as possible. Working in a startup allowed me to come up with my own ideas and implement them or giving my opinion about a feature.

We also worked on A/B tests to increase app monetization through new ways like partnerships, free trial and advertisement.

From the technical part, we used Kotlin, MVVM architecture and libraries like Firebase, Coroutines & RxJava2, Retrofit, OkHttp, etc...

Cashquizz

Introduction

Cashquizz is a trivia game app. You can play daily tournaments to earn coins, gems or real prizes. You can also challenge your friends on a specific topic. When you have enough coins, you can redeem them to earn rewards.

The app already has more than 1 million downloads.

My missions

I worked as an Android Lead Developer in a team of 4 people composed of two CEO, a back-end developer, an iOs developer. My mission was to handle the implementation of the Android app from the mockups until the final testing and the release.

I was working closely with the leadership team to define development plans and to estimate tasks. The tasks consisted of developing new features but also refactor, improve the code and fix bugs.

When implementing new features I was totally free of choosing the architecture, libraries and design patterns to use. That's why I started applying the MVVM structure, using RxJava and write clean code.

Being Lead Android Developer in that project taught me a lot. I had to respect deadlines, being able to fix any issues on my own and handle the project complexity in a short amount of time.
