- Prototype/MVP: Four lane capable base station to allow drive-thru order takers to communicate with drive-thru speaker posts (microphone/speaker). System was built using Go (Golang) and Ubuntu Linux. Prototypes included: * Multi-homed Bluetooth units/headsets and single controller distributing audio via USB sound cards. Use CGO in conjunction with vosk for voice commands and Pulse Audio for audio processing. * Headsets attached to/controlled by Samsung Galaxy Tablets using cross-compiled GUI (fyne.io) and speech-to-text processing (vosk) for voice commands. Audio and control data shipped to Linux units at speaker post via Wi-fi through system controller.- Using Go, created an audio control system to feed audio to/from a Voice-Bot (audio from/to drive-thru speaker post via a proprietary serial port device). Provide ability to process operator interrupts and audio control via onboard GPIO (USB Serial). Audio supported via CGO/Pulse Audio libraries- Design/Develop/Deploy/Support and and handover of Go based distributed system to ETL Xenial Point-Of-Sale (POS) data, and send JSON packages to external end-points. Multiple services included: extraction of full daily transactions from MariaDb databases (8200+ stores), extraction of single POS transactions from Amazon SQS (3000-4000 transactions-per-minute, 1.5+ million per-day), and an overall controller/scheduler of extraction tasks. Services run as daemons and orchestrated via SystemD and RabbitMQ. Provided command-line utilities/reports appropriate for support personnel.- Development and deployment of various extraction utilities written in Go using MariaDB/Postgres to deliver translated data to external endpoints.

- Lead Developer for system which extracted/aggregated (ETL) from a variety of internal/external sources and normalized data from 23000 +/- restaurants worldwide, written in PHP and sent to external endpoints.- Extraction and posting system(s) for non-SICOM POS systems (which I reverse-engineered)- Systems an environments to facilitate electronic inventory ordering from restaurant food distributors- Focus on the next generation of SEMS (see below) brought virtualization (VirtualBox) and its issues, as well as standardized development environments. - Minor foray into Data Science/Analysis/Forecasting/Reporting using Python as the primary analysis tool. - Design/Develop an ETL system in PERL to automate the extraction of data delivered nightly from point-of-sale systems (POS) via email attachments (contents generally contained a large CSV file or multiple CSV and binary files). This system serviced three generations of POS systems. The data was transformed and loaded customer MySQL databases for reporting. - In addition to data posting tasks, other efforts included: creating reports (financial, inventory, product, etc) using PHP and the RLIB Open-Source reporting package for the web-based SICOM Enterprise Management System (SEMS). SEMS uses a proprietary framework developed using PHP/JavaScript/MySQL. The SEMS system (and its PERL ETL system) will see 20 years of service in December 2024

- LLC formed by myself to provide contract programming services. Services provided were primarily in the area of web programming (PHP/JavaScript and PostgreSQL). Highlights: - Car parts cataloging website with database manipulation and conversion from MS-SQL Server to PostgreSQL - Web-site for a t-shirt vendor where text could be placed dynamically on the t-shirt. - Visual Basic (Version 6) Plotting package for an HP Vector Network Analyzer. Plots included Return Loss, VSWR, Frequency Response, Extended Smith Chart, Time Domain, Group and Phase Plots

A startup company which provided internet access over cable through a cable box and a wireless keyboard.- Web based (FreeBSD) email client in PERL using a CYRUS IMAP Server (PostgreSQL was used for account information)- Application in the “C” programming language (early Linux) to handle up/down stream communications (send key-clicks to browser processor and returned images changes to client session). - As product deployment hit critical mass, developers were asked to help support and deploy the product in the cable plant. After several installations, I was tasked with the responsibility of managing Network Operation Center to provide both product technical/installation support. Additionally, analyzed service contracts, service level agreements, and Operation's processes.

- Product development of the “Sniffer”, a Continuous Emissions Monitoring System (CEMS) using C and Unix (SCO and Interactive).- Applications were developed in “C” (with an understanding of Federal/State Dept. of Environmental Protection Regulations) to report on power plant stack emissions, and track/report on operations - reports were submitted to Federal/Local EPAs. A proprietary language was used to download into/manipulate PLCs (no ladder logic written) and develop applications to communicate and manipulate gas analysis equipment via PLCs (GE & Allen Bradley).- Developers were required to field product support calls – I was given the opportunity to start a support department, developing pricing for support contracts, and initial processes and procedures.

As an Electronics Engineer I was introduced to the world of pure research and development in the area of applied sonar signal processing. Many tasks were related to the extension of older military hardware through commercial hardware integration: primarily Sun Workstations (UNIX-OS) and the C programming language. Research efforts included: creating signal processing systems using Matlab and then transferring them to C using LinPack libraries and other numerical recipes for speed enhancement and prototyping tactical displays in the X-Window system. In addition to programming, laboratory time was spent becoming proficient using 28/14 track analogue recorders, spectrum analyzers and related equipment to supply and analyze sonar data.
