Dear client, I specialize in building HTML5 banners (and animation), animated gifs and static jpg/png in different fields for many media platforms such as Google Adwords, DoubleClick, Adform, Adroll, Sizmek, Adriver, AdFox, AppNexus, TradeDesk, Celtra, IAB, etc. Message me and I'll send you many examples. Also, I have great expertise in flash/swf. Working with me you will get a result in time and I will try to apply my 14+ years experience and the best practices to achieve the best result. Please note: I always try to produce high-quality products according to your needs and always keep agreements. HTML5 Tools: I prefer to create banners using plain html5 coding: html+css+js (Greensock/GSAP/TweenMax library for animation). Sometimes, I use special tools such as Adobe Animate (createjs) or GoogleWebDesigner Look banner's portfolio [censored]

Good working skills in HTML5 Game Development, Construct3, Construct 2, Flash game programming, flash designing and 2d Animation, E- Learning Presentations.

I am a software engineer with a B.S. in Computer Science and over ten years of professional experience in building web and mobile applications. I am skilled in all aspects of the full software development cycle, from requirements gathering and planning through development, release, and maintenance. In other words, I can do everything you need to build your app from the ground up and get it on the market. Whether you are starting with a rough concept or already have extensive specifications and wireframes, I will work with you to turn your idea into a reality. Looking for someone to do maintenance or upgrades on your existing project? I can learn your codebase quickly, fix bugs, refactor messy code, and add new features as needed. Looking for a top-notch developer with superior attention to detail for your government/military SBIR contract? I have 3 years of extensive experience developing training simulations, virtual classrooms, and other R&D applications for SBIRs. My rates may seem high, but that is because I am very fast and very good at what I do. Remember that the value you get from a freelancer should be measured in productivity per dollar, not dollars per hour. Less experienced developers typically take many hours or even days to complete tasks that I can complete in an hour; and end up costing you _more_ money despite their lower hourly rates. A few quotes from clients: "You've been one of the best connections through Upwork to date in every aspect" "Please understand that you are soooo much faster than anyone else I deal with. It's a gift" "I'm not exaggerating when I say this man is the best freelancer I've ever had the pleasure of working with." I specialize in the cross-platform development with frameworks like the Unity engine and Adobe AIR. These frameworks enable rapid development of cross-platform iOS, Android, and web applications at a significantly lower cost than developing native applications separately. My main focus is on the Unity engine and C# programming language. Unity is a cross-platform engine designed for 2D and 3D games and other real-time interactive experiences. I am an expert-level engineer with C# and with 2D, 3D, and VR game development in Unity. My skills encompass nearly all aspects of the Unity Editor, including scenes, UI, prefabs, extensions, assets, etc. I'm also an expert in ActionScript 3 (AS3) and the Adobe AIR framework, as well as the add-on Starling engine and Feathers UI library/SDK. I work quickly, design strong solutions, write clean and professional code, and learn and adapt skillfully to new challenges. My project experience ranges from productivity and social networking applications to educational software and 2D/3D games. Please review my portfolio for examples of my work. As a domestic developer and native English speaker, I offer higher quality of service and communication than most overseas providers. I pride myself on being faster, more responsive, and more dedicated than your average freelancer. Your satisfaction is my top priority. Freelancing is not a side-gig or hobby for me; it is my full-time occupation, and I bring all of the dedication and skill that entails. Your project will never be relegated to my spare time or "when I get around to it". Although my weekly availability may fluctuate as I manage projects with multiple clients, I can typically dedicated between 5 and 20 hours a week to a client depending on the needs of the project. -------- SERVICES: *Full-cycle software engineering --Cross-platform development for desktop, mobile, and WebGL --Consult with client on goals and strategy --Design of interface and graphics (if required), with mockups --Production of music (if required) --Development of clean, efficient code, customized to your application's needs --Responsive user interface code that looks good and works well on any screen size/aspect --Communicate with client on development progress and milestone completion, including providing testable builds to the client as work progresses --App Store/Google Play app publishing and descriptions (if required) --Customer service and support; handle customer bug reports, complaints, and feedback with friendly and positive attitude (hourly pay only) *C# *Unity *Java *Python *AS3 / AIR / Flash / Starling / Feathers / Flex *Git/Mercurial *GameSparks integration (frontend/backend) *Firebase integration (frontend/backend) *Image editing/texture editing/graphic design *Music *Copywriting, in-app text as needed *PHP / JS *Laravel 5 *MySQL While I have a wide range of skills, I am only one person and there are limitations to what I can realistically do.
