I developed two premium content-streaming Android applications and their library. This application has millions of users across the world. The most significant thing I've done was making the UI code more robust. Until then, there had been more than two bug fixes per week on the UI. After that, we only changed the UI if the specifications changed.

I worked as the sole senior Android engineer building an MVP of the app from scratch to publish and was in charge of publishing new updates. This is one of the two enterprise apps that I did for FocustApps.

I gave a speech titled "From Android Beginner to A 5-Star Freelancer." This was my first professional talk and I enjoyed speaking and sharing my knowledge on freelance work. After the speech, I obtained one business deal and a few developers who came up to me for a job—which was great!
The link attached is an article written about the talk (in Croatian).

I co-founded the startup, TaxiCentral. Our goal was to make a super easy-to-use app for people who want to order a taxi in Zagreb. Basically, the Uber for taxi companies.

From the start, I was responsible for the full development and everything in between—working on the architecture, documentation, partial design, testing, publishing, and promotion. This was my first published application.

Most of my work on this project consisted of updating the UI and implementing Android Wear API for an urgent release of the podcast application. This was my first Kanban project, made in Android Studio, and hosted on GitHub.

I developed the Android part while my college peers implemented the web crawling for this project. We won first place and received other perks like free office space for a year. The link attached is our pitch for the project (in Croatian).

BookBottles helps nightclubs easily manage reservations, table inventory, guest lists, client profiles, and transactions. On this project, I implemented the communication between the client and our developer.

I worked on this mother-targeted app that was also #1 for downloads in its country. I specifically developed the Android version from scratch with another developer and was mainly in charge of the UI part. This was the most fun I had because of the various customization I needed to do.

For this project, I built an Android app with a Parse-based back-end from scratch for a pub-crawling brand. In addition, I set up everything so the founders could easily add the events to the Parse back-end.

The client’s goal was to publish a pub-crawling Android application to the Google Play Store. They chose me to develop it after I gave a review of the two previous developers' code.

On this project, I implemented the full development of the Android and Parse back-end, doing the weekly tasks that I had brainstormed with the client. I also migrated the app from Eclipse to Android Studio and the back-end from DreamFactory to Parse.

The client wanted the completion of a partially completed app (70%). They had previously employed four freelance developers; who, one after another, all worked on it a bit and then bailed on. The code was in the worst condition I've ever seen and the client had a very tight schedule.

I worked on the UI changes, database, and REST API without improving the code because of the tight schedule and budget limitations. The client ended up delivering a fully developed app on time.

For Insigter, I managed the project via Trello in the idea stage and then moved it to the Bitbucket issue list. I also led two Android developers, added Facebook likes, added Twitter followers, and fixed a few bugs.

Moviez is a social media app that makes movie recommendations and on this project, I managed the development. Eventually, we discontinued the development because of a lack of a good monetization strategy.
