Development Staff Engineer

Tools: used: C/C++, Python, QT, Matlab, Atlassian tools, NSIS, numpy, scipy, Eclipse, scope, visual studio, google set(google drive, docs, aodocs etc.), lucidchart, slack

Responsibilities:

• Leaded python-only project for next generation of a complex automation test system. I joined the designing of its architecture and function specifications, documenting, developing and debugging code, writing unit-test cases.
• Developed drivers for different preamp cards.
• Designed and developed pattern quality metrics tests, write current optimization test, SAM error test, gray code error test, fast-vga test, and modified SEAM test to check quality of media from different manufactures.
• Developed Prism test based on python, Matlab, and C/C++ on windows. It includes Prism server, client, and GUI development, and becomes one of the critical media quality tests used at all Seagate sites around the world.
• Developed Prism test including GUI purely based on QT, python, numpy, and scipy on RedHat Linux installed on Aperio box. It dramatically improves test performance.
• Wrote documents, maintained and added new features, and released prism test for several years.
• Using Atlassian tools to track bugs and progress, review and manage code, build and test releases.
• Providing Prism, Chirp, and other support for different sites across the world.
• Developed APIs to call xyratex functions direct from python using C/C++ in Visual studio 2010 (VS2010).
• Porting FCL test scripts into python code.
• Tested heads and media for new products, processed, analyzed, and interpreted the test results, then optimized these tests.

Software Engineer

Tools: used: C/C++, Python and packages, GUI, XML, SQLite, Ultra-sound systems, Scope, Subversion, NSIS, Jira, Eclipse

Responsibilities:

• Developed FirstAssist to simulate different probes to detect defective channels in ultra-sound systems and report test results in PDF format. It includes a GUI developed by Python, wxPython to control system settings, test cases, test suites, graphics display, and interactions.
• Developed firmware for FirstAssist hardware using C, Silabs USBEXpress, and Keil embedded development tools.
• Developed an interface to flash new firmware. It is developed using Python, C, and Silabs USBExpress dynamical libray.
• Integrated database with FirstAssist using SQLite so that it can keep test results. Managed source code using subversion and tracking bugs using Jira.
• Wrote documents for FirstAssist verification and validation.

Senior Software engineer

Tools: used: Python, C/C++, Matlab, GUI, Bash, Linux, Eclipse, Scope, MDW

Responsibilities:

• Developed Aperio online help function and a bi-directional file transfer function between the control center and Aperio boxes, which dramatically improved users’ convenience.
• Developed an Aperio package to control power board automatically, and an auto-update module to upgrade python packages and distribution in Aperio.
• Developed python and Matlab programs for Aperio data post-processing, which is more than 10 times faster than the legacy code.
• Fixed socket bugs between the control center and Aperio boxes.
• Optimized hardware system configurations for a new media (DTR) and tested its compatibility
• Tested different hard drive media (DTR) from different manufactures.

Developer & Researcher

Tools: Used: C/C++, Perl, Cshell, Java, Matlab, HTML, GUI, SQL, GMT, MS Access, Digital Signal Processing, Filtering.

Responsibilities:

• Java programming for processing instrument responses which speeds up one-third comparing with some other commercial software.
• Joined the Fissure-Matlab project to manage huge seismic data. My duties were to design and develop GUIs, write documentation, specify functions, test & debug, and maintain the software.
• Developed programs to automatically and remotely retrieve the GPS data, pre-processed them, converted and archived them.
• Developed programs to get the positions using GPS Point-Positioning strategy and ambiguity solutions etc. techniques.
