  • Building on Ethereum: With Solidity and React

    Futurescale, Inc.

    In-App purchases represent an undeniably huge potential revenue stream for any game or application. Consider that Fortnite sold over 1 billion dollars worth of in-game purchases in less than a year from its inception. Most traditional game platforms are "walled gardens" where all the assets that gamers purchase come straight from the company who wrote the game. That's good for the company; they're the only source of magic swords. But for the players, frankly, it stinks. With Ethereum, those…

    In-App purchases represent an undeniably huge potential revenue stream for any game or application. Consider that Fortnite sold over 1 billion dollars worth of in-game purchases in less than a year from its inception. Most traditional game platforms are "walled gardens" where all the assets that gamers purchase come straight from the company who wrote the game. That's good for the company; they're the only source of magic swords. But for the players, frankly, it stinks. With Ethereum, those assets could live on the public blockchain and actually be owned by the users, who could sell or trade them like CryptoKitties or any other ERC-721 Non-fungible Token (NFT). When a player tires of a game after a year or two, she could sell all her assets to other players to recoup her investment.

    This is the vision behind the In-App Pro Shop, an application the author built and describes in detail in the book. The source code is available on GitHub, so you can download it and follow along, learning the Ethereum development ecosystem as you go.

    Any developer seeking to learn Ethereum smart contract development will have many of the same questions:
    - What language(s) should I use?
    - What blockchain tech stack do I need to get started?
    - What framework(s) will I use to build the UI?
    - What should the project structure look like?

    The answers to these questions lead to even more, and the options can seem overwhelming. This book covers most of them, as well as many of the the eventual problems you'll face once you're project is growing.

    For instance, what happens when your contract reaches the maximum size and can no longer be deployed? Or, how can your contract get information from off the blockchain, like current Ethereum exchange rates?

    Gain hands-on experience with PureMVC, the popular open source framework for developing maintainable applications with a Model-View-Controller architecture. In this concise guide, PureMVC creator Cliff Hall teaches the fundamentals of PureMVC development by walking you through the construction of a complete non-trivial Adobe AIR application.

    Through clear explanations and numerous ActionScript code examples, you’ll learn best practices for using the framework’s classes in your day-to-day work. Discover how PureMVC enables you to focus on the purpose and scope of your application, while the framework takes care of the plumbing in a maintainable and portable way.

    * Get a detailed overview of the PureMVC process for developing your application
    * Model the domain by designing the schema and creating framework-agnostic value objects
    * Implement framework-agnostic View components that expose an API of events and properties
    * Use the Proxy pattern to keep track of value objects and hide service interaction
    * Facilitate two-way communication between a View component and the rest of the application
    * Stitch the Model and View tiers together with command objects in the Controller
    * Manage problematic View component life cycles, and learn how to reuse the Model tier

  • Page Fight

    - Present

    Page Fight is a gamified solution to collecting reader reactions to book marketing materials. While it is focused on helping authors and publishers determine the best titles, taglines, blurbs, and covers for their books before publishing, it also acts as a unique discovery service for readers.

    I designed and built the HTML5 single-page application from the ground up with a mobile-first design using Angular, Bootstrap, jQuery, Firebase, and Node.js on Heroku.

  • CWCT - CDL Waveform Compliance Tester

    -

    Secure communications between UAVs (Unmanned Aerial Vehicles, or 'drones') and other UAVs or ground stations using the CDL (Common Data Link) specification is an extremely complex proposition. And testing that a vendor's CDL implementation actually meets all the criteria of the spec is even tougher.

    Secure communications between UAVs (Unmanned Aerial Vehicles, or 'drones') and other UAVs or ground stations using the CDL (Common Data Link) specification is an extremely complex proposition. And testing that a vendor's CDL implementation actually meets all the criteria of the spec is even tougher. CWCT is a custom hardware and software solution for verifying standard CDL waveform interoperability between candidate platforms or terminals and network systems in both classified and unclassified environments.

    JITC (Joint Interoperability Test Command) chose CVG/Avtec to build the CWCT hardware, and Futurescale was chosen to build the GUI for the CWCT. I provided the entire client-side architecture and development of the first shipped version of CWCT.

  • ChannelMaster ELS (Enterprise Lending System)

    -

    ChannelMaster ELS streamlines the way correspondent lenders manage loans as they travel through the pipeline from lead to funding. By organizing loans in a central hub, it allows loan agents, processors, underwriters, closers, funders and others involved in the mortgage origination process to work on multiple loan files at the same time. The system also features lifecycle recognition ability, ensuring the processor completes required actions first and prevents noncritical actions from causing a…

I provided Adobe Flex development in support of the ChannelMaster customization for Chase Manhattan Bank.
