WORK EXPERIENCE

Team Lead, BlackBerry OS / Wireless Groups
February 2012 - January 2014 (2 years)

Led a team of 4 developers assigned to time sensitive projects in need of technical expertise and leadership

• Performed issue triage and codeline integrations in addition to being a productive developer on the team
• Exposed to agile methodologies; adopted principles from Scrum & Kanban suited to team and projects
• Emphasized software quality; established clear coding guidelines; thorough design and code reviews and use of wikis, continuous integration (Jenkins), static code analysis (Klocwork), unit and functional testing tools (Check, Robot Framework)

Project: Integration of a new Wi-Fi chipset on BlackBerry10

• Led project team of 6 developers spread across multiple development sites
• Managed relationship with a large chipset vendor and worked together to implement and support:

• Hardware bring-up and porting to QNX/BlackBerry 10 OS
• RF hardware calibration and validation at the factory
• Station mode, Mobile Hotspot and Wi-Fi Direct/P2P functionality including Wi-Fi Display
• Product Wi-Fi Alliance certification

• Implemented functionality between the BlackBerry proprietary WLAN Manager, customized version of the open source WPA supplicant and a network driver within the QNX io-pkt stack (based on NetBSD)
• Led investigation and resolution of complex system level issues ranging from subsystem interaction during startup to poor battery life performance

Key Accomplishments:

• Achieved fastest productization of a new Wi-Fi chipset on a BlackBerry phone, with KPIs (throughput, power, driver stability) meeting or exceeding mature solutions
• Championed and established processes for effective joint development with vendor

Project: Design of telephony middleware for BlackBerry10

• Led a project team of 9 developers, a majority of whom were new to QNX and C development
• Designed and built a critical system service from the ground up which provided:

• A framework to support call control, call history and settings for multiple phone “lines”
• Utilities for phone number manipulation (formatting, “smart” dialling & canonical representation)
• A cellular phone “line” (for both GSM & CDMA technologies) as per requirements from carriers
• High availability and reliability for emergency call scenarios

• Implemented modules for a QNX Persistent Publish/Subscribe based JSON API parser/dispatcher; state machines for the phone/call and audio subsystems and other core framework components responsible for threading, event management and logging

Key Accomplishments:

• Achieved design goals of building a reliable service capable of recovery from a process crash mid-call; passed architecture review board and security research group audits with no resulting change requests
• Successfully staged deliverables to aggressively enable alpha, pre-certification and field testing
• Mentored and built an effective agile team whose “definition of done” set a high quality bar

Software Developer, QNX Platform Team
February 2011 - February 2012 (1 year 1 month)

Member of a rapid prototyping team on the leading edge of BlackBerry’s transition to the QNX OS

• Messaging, SMTP functionality on Personal Information Manager (PIM) prototype on PlayBook
• Networking functionality on a BlackBerry JVM on PlayBook email over Wi-Fi demo
• Basic Facebook functionality (get friend list, post to wall) for a native application demo
• Driver for a tunable capacitance controller (STHVDAC-303) for a hardware team prototype

Software Developer, WLAN Radio & IP Transport
June 2008 - February 2011 (2 years 9 months)

WLAN Protocols & Firmware Developer, Intern

May 2006 - September 2007 (1 year 4 months)

Member of a team that worked on the first dual-radio Wi-Fi capable BlackBerry devices

• Maintained the core Wi-Fi stack and ported multiple vendor network drivers to the BlackBerry RTOS
• Implemented standard and proprietary IEEE 802.11 features covering power management, quality of service, call admission control, regulatory domain, rate adaptation, connection and scan management

• Experienced in IEEE 802.11 and TCP/IP protocol analysis through numerous investigations of connectivity and Wi-Fi interoperability issues reported by customers and field testers
• Implemented a DNS stub resolver for the BlackBerry IPv4 stack; also maintained DHCP, ARP clients
• Devoted significant time and effort to maximising battery life performance; BlackBerry’s “always on” Wi-Fi use cases required aggressive power saving techniques with complex trade offs

• Profiled and improved TCP and UDP throughput performance on multiple hardware platforms
• Eliminated all instances where the Wi-Fi stack starved JVM UI threads beyond 60 fps budget
• Recognized by team for taking initiative to improve code quality and eliminating technical debt

• Developed a popular tool to perform “shelving” on Perforce clients (before it was added in version 2009.2)
• Mentored new employees and delivered Wi-Fi training to remote product development sites
• Involved in Wi-Fi chipset evaluation and selection for future products

Key Accomplishments:

• Led efforts to port the core Wi-Fi and VPN stacks to the Qualcomm REX OS to support CDMA device variants; the resulting code reuse was considered a big win for the department as highlighted by the VP
• Led Wi-Fi development on several BlackBerry phones (Storm2, Tour2, Curve 8530, Style), from hardware bring-up of chipsets to supporting Wi-Fi Alliance certification programs
