• Manage a team of eight developers, located in different geographical regions, in a pseudo Agile/Scrum environment. Team members range from co-op students to Principal System Software developers.
• Responsibilities of the team include: WLAN chipset bring up, OS driver maintenance, evaluation of new chipsets for future devices, performance improvements (i.e. throughput, CPU usage, battery life, etc.), WFA.
• Complete employee year-end reviews, regular 1-on-1 meetings, goal setting, and compensation reviews.
• Conduct interviews (technical and behavioural) for co-op, developer, and lead positions.
• Lead weekly sync. calls with the three vendors currently being used to source WLAN chipsets. Chipsets used include: TI’s 128X family, Broadcom’s 43XX family, and Qualcomm’s WCN3660.
• Perform triage of incoming bug reports. This includes doing first pass analysis, determining if a bug fix or a new feature is needed, estimating effort, and setting priority and target release.

• Maintained, designed and debugged the WLAN subsystem for all BB10 devices (25 devices launched to date).
• Led code reviews for WLAN service layer applications, WPA Supplicant, and OS drivers.
• Debugged system issues including problems in the chipset firmware, system interface (SDIO/PCI intf., DMA, OS and IP stack interface), Physical Layer, MAC/Data Link Layer, and Networking Layer (protocols such as ARP.
• Supported WFA Certification efforts by updating the Sigma Sample DUT (i.e. WTE) for new test plans and debugging failures in existing test programs including 11a/b/g/n/ac, Wifi Direct, WPA2, PMF/MFP, WPS, Miracast.
• Designed the development process used by a 25-person team. This included creating the tools and rules to make it easier to checkout code from several repository control systems, post to code review systems and update.
• Designed new white box and black box unit tests for use by the testing teams.

• Project Lead for Sangoma’s next gen SS7 library. Wrapped Trillium’s SS7 stack (OS abstraction, MTP2, MTP3, and ISUP) in a multi-threaded C API library that allowed it to be used by the FreeTDM signaling module of.
• Lead developer for hardware test bed. This involved developing and maintaining Bash scripts, Perl scripts, and multi-threaded C applications to unit test PCI/PCIe and USB telephony (T1, E1, PSTN) interface cards.
• Responsible for developing and debugging patches for Linux and Windows kernel drivers. This involved dealing with new APIs as new kernels were released, debugging PCI/PCIe, DMA, and IRQ issues.

• Managed the technical support team that grew 300% during my term. The team was responsible for installing, configuring, maintaining, and validating installations of Sangoma’s hardware and software products for.
• Ensured that Sangoma’s technical support was of the highest quality by creating documentation (wiki pages, how-to’s, and white papers) and training six support and field application engineers. Areas of support.

• Architected and coded a SIP call monitoring application using Visual Basic, C++ and C. A C++ DLL was created to allow the VB UI to access data from a C wrapper library of TShark.
• Designed a 4-layer, 4-port T1/E1 to PC/104 PCB layout.
• Created a custom CSA approved chassis for the next generation of products.
• Provided technical support for PRILink’s line of ISDN-PRI protocol monitoring equipment including troubleshooting hardware, software, protocol, and traffic management issues.
• Represented PRILink at ITU Telecom World 2006 in Hong Kong, China.
