Principal Software Engineer and Architect │ Senior Staff Engineer• Architect on the SAGE product which is an IoT home automation and security system and served as team lead for a number of related sub-systems while establishing a control hub and remote client simulator used in early development and testing. • Created new procedures using the Lua programming language by integrating a new process into the existing build system to minimize adoption effort by reducing the lines of code required by 60 to 80% and development time by 70 to 90%.• Wrote a Java servlet based communications server used on SAGE product during development and testing. • Developed the original Android app that is the basis for the current SAGE app. • Lead team responsible for adding support for WebRTC to app while developing a WebSocket bridge server to be used for ICE/STUN/TURN and WebRTC startup negotiations.• Served as team lead for multiple projects including: a QAM based STB for multi-tenant units (MTUs), a satellite to QAM converter to allow satellite STBs to be used in MTUs and a digital off-air tuner dongle for STBs.• Created a GUI designer that allowed ‘drag-and-drop’ screen design to be used for automated testing as well as for set-top box development.• Developed an Eclipse based application to parse MPEG-TS packets and display them in a graphical tree view. This involved custom embedded code in a STB to capture the packet stream from the satellite feed. The parser was designed to be a universal bit-stream parser.

• Ported a third party RTOS to the Elastic modem which contained an embedded ARC processor.• Wrote the firmware design specification for the IEEE 802.1Q VLAN support for multi-port modems.• Worked with Board Support Package (BSP) and device drivers which included UART, multi-port DMA, HDLC, Ethernet, and QAM.

Delray Beach, Fl

Senior Firmware Developer │ Chief Software Architect • Developed firmware for the Broadframe ADSL DSLAM/router emulator which included an ATM SAR driver, Ethernet driver, TCP/IP stack, Windows user interface, and firmware upgrade via user interface.• Developed a multi-port ISDN router/access concentrator and ISDN terminal adapter.• Designed a new runtime loadable low level driver subsystem, time division multiplexed bus driver, and Serial I/O communications drivers (Async, HDLC, inter-chip, etc.).• Created an ISDN telephone system, which routed voice packets via UDP/IP as a technology demonstrator for a US military IP based field telephone system project. • Developed a well-defined and documented interface that allowed protocols and device drivers to be plugged into the existing code base and thereby drastically reducing delivery of solutions for new platforms from 4-6 months to 2-3 weeks.

Boca Raton, Fl

Developed firmware for ISDN terminal adapters. These terminal adapters were for both the US and Japanese markets. My efforts included:• Design of a technique for automatic baud rate detection for the UART.• Integration of V.120 and PPP protocol support.• Design and development of a FLASH EEPROM firmware upgrade utility.• Support for telephone (POTS) connections to provide voice communications.• Development of a Windows based configuration and product registration utility.Developed Fax/Data/Voice application software for the Boca Research line of modems. This Fax application was written in Borland's Delphi (Object Pascal.) and required work in the following areas:• Database access programming.• Windows screen design and management.• Graphical image display and manipulation.• Windows inter-process communications.• Design and implementation of Delphi VCLs (VBX like modules).• Design of Delphi VCL 'wrappers' for DLL libraries.• Integration and enhancement of Visual Basic VBXs in the Delphi environment.

Boca Raton, Fl

• Developed the ROM based configuration utility (system setup) for personal computers. These efforts included UI design, memory map, and foreign language support.• Created test automation tools for the Personal Computer group including testing methodologies, hardware design specification, documentation, and project leadership.• Produced firmware and device drivers for various IBM minicomputers including I/O channels to IBM mainframe computers.• Developed compilers for IBM computers including the first C compiler for the processor that eventually became the PowerPC.
