    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.

    From simple to complex designs, I can provide a path that will take your concepts to designs and prototypes. Using a formal engineering process, I can ensure design specifications are met within budget and time constraints. My Hardware expertise includes: circuit design and analysis, schematic capture and BOM generation, and PCB layout and assembly. I have experience using several processor architectures such as AVR, PIC, and ARM. My software expertise includes: C/C++, C#, assembly, Java, HTML, CSS, SQL. I have experience building barebones firmware and RTOS firmware for several microcontroller applications. For more complex and versatile projects, I have experience designing high-speed FPGA systems using VHDL. I am able to simulate and verify designs before hardware is used. I primarily use Altera’s development tools for FPGA software.

    I have years of experience working in many different fields. As a result I have developed multiple technical skills and an ability to adapt quickly to a variety of environments. I have a strong work ethic and am happy to work on my own or as part of a larger group. I am passionate about doing quality work. My strengths include problem solving, programming, learning new systems and languages, written communication, mathematics, attention to detail, and performing technical tasks with consistent accuracy. I have a Bachelor's Degree in Mathematics and Computer Science from the University of Oregon, and I have experience working in both a bio-informatics research laboratory and a network security lab. I have more than 10 years of programming experience (Python, Java, Bash, SQL, C, HTML, CSS) and have worked as part of a software development team. I am currently the manager of a local computer repair company that focuses on Apple products, and as a result I have acquired extensive knowledge about macOS and computer repair, including micro-soldering and motherboard repairs. I also have experience installing and using both Windows and Linux. In my free time I study Latin and other languages (German, Spanish, Mandarin, Russian, Greek), and I love learning and applying my knowledge to solve new problems.
