Steve C. Email & Phone Number

Plano, TX

Low level software development for 5G radio products.

• Manage software development process, provides process training. Manage software release process. Manage offsite team. Perform task prioritization, feature requirement analysis, scheduling, and development. Brought in.
• Train and lead new team of software engineers offsite. Created various forms of training documentation to assist bringing new team members on board (coding standard, software development process, and existing software.
• Test and evaluate components. Worked with RF Engineers to determine and document micro-controller requirements. This includes software controlled bias loops, local oscillator nulling, automatic transmit power control.
• Design included one binary to support ten different hardware implementations (for different RF bands), and both TX and RX modules.
• Document micro-controller design. Lead team in India to implement and test.
• Ported device driver from similar Ethernet switch to new radio (BCM 53125M).

TX

• Member of the Media Pump team on Cisco's CTS-3000/TX-9000 immersive TelePresence video conferencing systems. Team responsible for moving audio and video between network interface and Digital Signal Processors. Linux.
• Implemented/documented enhanced call statistics feature with remote cross functional team.
• Resolved hundreds of static analysis issues and compiler warnings with no collateral damage.
• Team lead for IPv6 feature on media subsystem. Analyzed current IPv4 implementation, designed dual stack approach with local and remote team members.
• Feature lead for "Flux" protocol used for used for media resiliency under impaired network conditions. Documented requirements, design, test cases, and project plan.
• Took responsibility for lab infrastructure maintenance and upgrades (additional build servers, port capacity, IPv6 readiness, etc.).

TX

• Member of the Outdoor Mesh Access Point Team, for Cisco's WiFi Access Points (AP) (Cisco IOS based) and Wireless LAN Controllers (WLC) (Linux based).
• Setup and documented local build environment for APs and WLCs. Decreased AP build time from 4 hours to 20 minutes, and WLC build time from 10 hours to 1 hour.
• Analyzed difficult problem of Mesh APs not joining parent AP when un-related code changes were made (day one bug in IOS, fixed by IOS team).
• Assisted and documented build environment setup for a new AP, including source control repository setup.
• Led daily bug scrub meetings.
• Researched and presented "Transfer of Information" on how mesh APs determine a parent, and join a WLC, for Technical Assistance Center personnel.

TX

• Part of a two person team responsible for customer demonstrations of Cisco’s BWX 8305 WiMAX Base Station.
• Demonstrated effect of beamforming technology on bandwidth and “signal to noise” ratio.
• Managed product trials in Europe.

TX

• Provided assistance to Technical Assistance Center personnel to resolve field issues.
• Performed field test in Bulgaria and Mexico that validated interference reduction algorithm and base station to CPE handoffs.

TX

• Member of a team responsible for validating custom SuperCarrera ASIC.
• Validated ASIC and device driver performance for 10 port GigE Mapper card.
• Implemented software work around's in driver that enhanced silicon performance.
• Led team of five engineers to accelerate tests before ASIC spin. Documented validation procedures, analyzed test results.

TX

• Member of Device Driver Team.
• Developed device drivers for off the shelf ASICs used in line cards. This allowed bringing a new product to market faster, using commercial off the shelf silicon.
• Developed device driver for custom ASIC used in a single replacement line card. This allowed introduction of a cheaper, more capable line card.
• Designed and developed a pluggable daughter card object, used to change line card capabilities. Utilized C++ inheritance.

TX

• Added capability to both OC48 and OC192 for System Fast Reserved Switching, a form of automatic protection switching in the event of a signal failure. Switch times met system requirements with 50% margin, down from two.

TX

Developed VxWorks based device driver and embedded application software.

Germany

Developed automated T1 Modem Test Station.

TX

Analyzed test needs, and did preliminary design for all program test equipment for a Local Multipoint Distribution System.
