    I am a self-employed computer programmer who, for many years, has built reliable software systems that provide recurring profit to their owners and quiet enjoyment to their users. Whenever possible, I provide fixed-fee estimates to my clients to protect them from unexpected cost overruns. I have many years of proven results in diverse settings. This experience, supplemented by a BS/BA degree in Mathematics and Computer Science (Boston College), a Masters of Science degree in Computer Science (Fairleigh Dickinson University), two years of study in a Ph.D. program (Stevens Institute of Technology), and a Graduate Certificate in Object-Oriented Design (New Jersey Institute of Technology) facilitates a unique synthesis of formal scientific training to augment practical industry experience. I have years of experience with C++/C#/C, .NET, Desktop, JavaScript, Python, and various other web, mobile, desktop, and server development technologies. Many projects have included RS232, RS422, USB, GPIB, MIDI, Ethernet, and Bluetooth interfaces to external industrial controllers and equipment. My recent areas of research and self-study include the application of concurrent programming algorithms to complex problems that have, in the past, been addressed by linear/non-concurrent algorithms. To this end, I have purchased and configured an advanced 128 GB Windows 2025 server with a 48 GB NVIDIA RTX A6000 GPU and a 24-core Xeon processor. My recent successes include the design & development of a mobile (both iOS and Android) application deployed in a hospitality environment across several dozen venues nationwide. I have designed and developed the client-side application as an HTML5, CSS, JavaScript, JQuery, and AJAX cross-platform "hybrid" application. The device-side code runs within a C# (Android) or Objective-C (iOS) custom-developed "native shell" application that provides the HTML5/JavaScript application with device-specific functionality (e.g., hardware access, graphics) via an abstracted interface. I designed and developed the server-side as a custom-written Windows Server 2012 r2 RESTful Web Service written in C# with a SQL Server 2016 back-end. My experience also includes many years of successful desktop development for several local (NJ) pharmaceutical companies. Typical applications include advanced sales/marketing data analytic applications with graphics/charting interfacing with custom data back-end systems. I have extensive experience in consulting and off-site software development for organizations of all sizes. My skills include expertise in most major programming languages with extensive experience developing software applications in the C, C# and C++, Python, Ruby, VB.NET, ASP.NET, and JavaScript languages in the .NET/PC/Windows environment. I have developed stand-alone, networked, client/server, internet/intranet, and web-service applications for various management science applications. My experience includes over 25 years of customer-driven, results-oriented programming in the pharmaceutical, hospitality, and financial services industries with specialized expertise in off-site development, testing, deployment, and optimization of ad-hoc analytical applications for .NET, MS-Office, JavaScript, AJAX, ASP/ASP.NET environments. My commitment to quality, reliability, and honesty make me a significant asset to any information science undertaking. I am a US citizen. English is my first language. Thank you for taking the time to review my profile.

    I have designed and completed many iOS/Swift, Unity/C#, React Native/Javascript, and Flutter/Dart-based apps as a sole, lead, or co-developer and published them on the Apple App Store and Google Play Stores. As a contractor for NASA, I published a Unity/C# iOS/Android augmented reality app for their Visitor Center in Goddard, Maryland, called "WeatherSats AR." I am currently working on multiple contracts in Native iOS, Android, and Unity. On the backend, my expertise is in Firebase, Firebase Functions, and now Microsoft Azure. I co-founded two iOS startup companies with other developers. One is a social media app for craft beer, and the other is a SwiftUI animation-based app where you can draw a multiple-choice question animation and share it with and challenge other users. I have a B.S. in computer science from Rutgers University in 2004, graduating with a 4.0 GPA.

I'm an artist, game developer, project manager and teacher experienced in building custom apps and websites for small businesses as well as publishing my own projects. I'm a clear communicator and planner, eager to hear about your business goals. As a full-stack developer I can take your "back of the napkin" ideas all the way to working prototype, beta, production, and beyond by handling all database design as well as front-end code. As a game designer, I can take your game idea to new heights and create testable rapid prototypes for us to show to early testers before we create the next chart-topping Steam release. As a teacher, I'm comfortable working with beginners that have absolutely no programming experience. No challenge is too great for me! Happy to work within your budget to help you achieve your next project milestone.
