    Software engineer

    Sweden - Last active: 06/06/2013

    Summary Ever since I can remember technology has been an important part of my life, this has taken me from founding my own small technology company back in Sweden to working on projects all over the world. This same focus on technology also allows me to have a broad understanding of how technology is evolving and it has given me the ability to widen my knowledge which is now spread across several different kinds of technological areas. References will be provided upon request. Specialities I am an experienced developer within the mobile sphere having built both back office software as well as fully fledged content delivery and billing solutions for some of the biggest carriers in the world. Ive had several titles in top lists in the apple appstore and on carriers across the world. While mobile has been my main focus the last couple of years my base lies in web where I have developed solutions to allow companies of all sizes to have a presence on the web. I’ve built systems and websites for everything from small local companies to big global companies. For the last couple of years my focus on web has been towards Ruby on rails using a BDD philosophy having finished both big and small sized projects by successfully leveraging cucumber acceptance tests and story writing as well as unit tests based around rspec. While being a partner in different businesses I have also gathered skills in business planning and management.

    Experienced Corona Mobile Game and App Programmer with Benefits

    United States - Last active: 1 day ago - Portfolio: 7

    Hello! I'm an experienced and published mobile app and game developer. I've primarily used the Corona SDK for my cross platform game development. I've worked extensively on: * Box2D physics * Many of the Corona plugins (analytics, Facebook, all Ad platforms, etc.) * Cloud services (AppWave and App42, etc.) * Real-time multiplayer * In-app Purchasing * Push notifications * Advertising monetization (video, banner, interstitial, incentive) * Data storage (SQLite, JSON, cloud) Aside from coding, I also do quite a bit of drawing for basic graphic assets. I've done 100% of the assets for each of my games. I wouldn't call my design abilities a core strength rather a supporting ability where I can draw UI controls, basic sprites, etc. without the need for an artist. I'm available full time or as needed starting any time. No preference for team size or project stage. I work well with small or large teams and don't mind jumping into an existing codebase or starting from scratch. As for the **benefits**, I also have an existing codebase for general services that I don't mind reusing (with no licensing attached). Services include: * Complete In-App purchasing store * Real-time multiplayer framework * Push notifications and deep linking * Cloud based promotional services * Progression features including player profiles, leveling, perks and rewards, etc. * Facebook Login integration * Analytics Prior to the recent time I've spent developing games, I worked as a lead engineer in the mobile telecom world for over 12 years as a server side enterprise Java developer and SDK/tools developer. **Portfolio** I have 15 games published on the Google Play store, and 15 on the App Store as well. These games were all solo projects. I've done all design, development, and publishing.

    Full Stack Web Developer

    Spain - Last active: 17 days ago - Tests: 7 - Portfolio: 4

    Hello, My name is Dani and I'm specialized in web application development. I'm also currently working with Prestashop, developing and optimizing modules, customizing templates, among on other needs that our clients request. I'm fascinated about new technologies and about all the engineering work they have in their background, but I also enjoy exploring the not so new ones, and that's because meanwhile the first ones increase our productivity significantly, the second ones allow us to really understand what's really "going on there" and, therefore, to open our minds when facing a new problem. My goal right now is to achieve some experience and to prove to myself that I'm able to be as good as much of the great freelancers I have seen here. Feel free to contact me for any issue :) Dani
