For most of my over 10-year career, I've written and debugged a variety of software and have solved various types of problems. At Techno-Sciences, this was primarily software which handled communication between hardware devices with different protocols, and getting them to work together as a maritime surveillance unit. With Polycom, it was software which handled communication between Polycom's DMA and external hardware components such as phones, web services, and video conferencing devices. Then, with Spectra Logic, I wrote automated test code to debug communication between Spectra's backup software and various hardware storage devices, as well as cloud storage services such as S3. Next, with RK Mechanical, I programmed software to import product and price data from various APIs and data sheets and consolidate it. After that, with Exolvo Designs Group, I am enhanced software for a search-and-rescue antenna configuration system. And now, with Versity, I've done Golang programming for a data storage analysis tool and am currently doing bats testing for an AWS S3 gateway. In addition to my current contract at Versity, I'm open to freelance work in any field I find engaging, fields where I can put software together to solve problems and improve my knowledge. Skills: * bash/bats * Golang * github-actions * REST API * React.js * Docker * AWS * SQL Server * Python * MongoDB * Java * C++
