I was trained classically, writing C and C++ code for Wall Street trading powerhouses like Goldman Sachs and Lehman Brothers. Running on advanced Unix systems, these lightning fast applications pioneered the field of today’s realtime global Fintech. As the Internet spawned open source platforms like Linux, MySQL, NodeJS, and AWS Cloud API’s, my skillset evolved into a full stack portfolio, where I built powerful back-end server software and the front-end web portals to deliver large, complex datasets via intuitive web portals. The maturing of JavaScript as the main language of the web, both on the front and back ends, has validated my decision to adopt NodeJS as my main coding platform in 2011. Today, JavaScript forms the glue of most of my applications, running on Node on the server, and in the browser up front. After moving to the West Coast in 2016, and spending time in Silicon Valley, I ventured away from financial systems to innovative applications like Blockchain Protocol coding and Video Streaming/Ffmpeg. I also coded network traffic optimization software down to the fundamental layers of the TCP/IP stack. All these big data applications naturally led me into the design and coding of custom algorithms. Whether compressing/chunking a video stream to play on a low powered mobile device, parsing network packets for suspicious traffic, or generating large NACHA files, the ability to code an algorithm in plain C can make the difference between a successful production deployment, and non-performant code that never leaves the github repo. From my early career, I have made Database structure the centerpiece of my application design. Again, classical training in Dr. E. F. Codd’s model of Relational Databases has always informed my philosophy of how to structure an application’s data repository. With web-scale data, this field has grown to NoSQL and Graph databases. Now, huge datasets underpin the training of AI/ML models. I have kept my skills updated on these data technologies, and I combine the relevant elements of each to define the most appropriate data repository for my software.
