Xiaoyan (Jessica) W.

As a member of the Software group, contributed to feature development, modernization, and support for mission-critical L3 applications across Windows, embedded Linux, and VxWorks platforms. • Led the end-to-end design and implementation of situation awareness features for a network management application. Developed an MVVM-based UI, used Windows service, and PostgreSQL/SciChart for live and historical data visualization. Provided full support from prototyping to customer deployment. • Served as a key developer for the UI of a next-generation vehicular intercom system. Assisted senior leadership in selecting development tools and built the UI framework from scratch, including UI menus, call panels, hardware settings, and firmware update panels. Utilized C++, SquireLine, and LVGL on an embedded Linux platform. • Developed a .NET application to emulate L3 modem behavior via TCP/IP and OpenAMIP protocols, enabling antenna vendors to validate hardware without requiring physical modems. • Debugged and resolved errors for the MIDS JTRS project, collaborating with multiple teams through weekly meetings to troubleshoot issues across various system areas. Worked with the Green Hills Integrity RTOS. • Integrated legacy MIDS-LVT message application with new sw development settings using VxWorks. • Enhanced a Network planning tool by integrating a debug logger parser, enabling automated analysis of various modem logs. This feature filters relevant information, generates reports, visualizes system performance and errors, and simulates different networks. It significantly reduced debugging cycles and became a key selling point. • Upgraded Linkabit legacy windows form application, Python test automation and WPF tools with new features and compatibility fixes. Collaborated closely with the other teams. Ensured alignment with customer and internal requirements,

As a member of the Application Software for Windows Phone Group, helped to differentiate Nokia windows phones from other windows phones by developing and maintaining high quality applications. • Researched and prototyped the nearby share application on Windows Phone8.1 to ensure a very easy and pleasant experience with data sharing between devices. It used cutting edge technologies like 3D gesture recognition and Neighborhood-Aware Network technologies for nearby device discovery. • Key developer for access point settings application on WP7 and WP8. Participated from initial design to product release. Cooperated with Microsoft and Nokia testing teams all over the world to guarantee the network configuration on windows phone is able to work correctly with minimum user interactions. • Participated in design and implementation of On-device-diagnostic tool on WP7 and windows tablet to test multiple features on phone, including battery status checking, phone antenna switching, color display, gyroscope, life timer etc. Worked closely with test team and engine team to find the best solution for internal testing which ensured product quality. • Developed Nokia share application on WP8.0 which allows easy picture sharing between Nokia windows phone and Nokia windows tablet. • Insured WP7/8/8.1 application quality. Debugged and resolved application errors in different levels of the application, including driver, service and UI interface application parts.

Supported Nokia S40 GSM feature phones development in North America. • Led AT&T Address Book project. Played key role in feature implementation. Involved in software design, development, testing, cooperation with global teams and customer support. • Accomplished different carrier specific features development in a large range of UI components. E.g. Duel SIM support for provisioning; CMAS UI support; Java open API support in messaging; Phonebook server changes etc. • Acted as key UI developer on a challenged project which migrated Nokia S40 platform software to S30 hardware in a short period of time. Made sure basic UI functions working correctly. • Debugged and fixed software errors in many different UI components on Nokia S40 phones. • Successfully mentored new hires.

Ensured Nokia S40 CDMA feature phones software quality in North America. • Led team (promoted to team leader in April, 2006) to support UI platform, call app and message apps related software. Managed team resources and work load balance. Ensured team productivity. • A key UI support member for the smallest CDMA fold phone. Involved in both UI configurations and new feature development. Accomplished main tasks including: design and implement LED features on second display. • Responded quickly for in lab or on market product support, including trouble-shooting, error fixing, and software integration. Major focus area was UI platform which included panel library applications, layout, panel/menu server, common delegates etc.

• Participated in development of cable replacement SW for Bluetooth (BT) module. Wrote product specification and test case design document. Implemented configuration tool and test tool using MFC, TCP/IP, and CSR embedded BT stack. • Developed several RF test tools for Bluetooth module’s RF characteristic test, such as power consumption, modulation characteristic, adjacent channel influence etc. Used serial, parallel and GPIB port to control different test equipments for testing. Test equipment includes Agilent BT tester, signal generator, spectrum analyzer. • Enhanced control software for wireless communication between BT modules. Added new features and intergraded it with BT stack.
