    Web specialist

    France - Tests: 3 - Portfolio: 4

    I am a seasoned SW developer specialized in building/improving web UIs, producing browser addons (Firefox&Chrome) & Web data scraping scripts. I have passion for everything touching Internet and more particularly by: - web portals and mashup sites - web and television convergence. Web UIs: I design and remodel web User Interfaces to align to standard practices and benefit from state-of-the-art ergonomy. I'm particularly interested in complex and dynamic UIs mixing all kind of data (maps, videos etc...). My background is more in technology than graphic design and I get my inspiration from existing best sites. Data scraping: I develop scripts for collecting information from various internet sources and utilize for mashups and any other application or website bringing added-value to users. From a work ethics, I do not participate to any data scraping activity intended at copying and redistributing commercial information in a different form. I have developed my own graphic scraping environment which allows turning data and generating scripts for customers in record time. Addons I have developed several browser extensions in domains as varied as commercial sites, greasemonkey applications, Cloud based applications etc etc ... Those addons improve productivity, consolidate data and bring added-value to users. I develop both Firefox and Chrome extensions. Finally I am interested in building lasting relationships with my customers. From language perspective, I am working on a daily basis with european, and NA based customers.

    Experienced Corona Mobile Game and App Programmer with Benefits

    United States - 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.
