Rotary Steerable Systems• Architect and develop embeded firmware to be used on the next generation of rotary steerable systems: C, RTOS, ARM7, 1553, CAN, SPI• Developed test firmware for a test fixture to qualify sensors used on drilling service: magnetometers, inclinometers, encoder, sampling at the early stage of the project.• Performed integration test of the new firmware code with surface software to qualify the new firmware for a release in a short time; got Applause Reward in Service Quality for this work.Quasar Pulse MWD/LWD tools• Performed the firmare changes and met the deadline on a short notice for redesigned boards on Quasar DM200.• Got MVP Award for this work. GeoTap IDS Tool• Contributed in developing embedded firmware for new features and bug fixes (as well as testing and finding bugs to fix).

• Designed and tested electronics hardware for downhole and surface tools targeted at high temperature (200C and above).• Developed and gained experience in embedded microcontroller-based system software architecture/design, device drivers, communication protocols, and hardware/software interaction.• Implemented functional GUI interface for system-level test to automatically control testing equipment.• Designed and supported .NET software programs to enable firmware engineers to visualize and analyze subsurface data.

•Fabricated thin film infrared sensitive material using sputtering machine.•Etched holes and lines in silicon wafer using the Reactive Ion Etch tool.•Measured and analyzed samples’ temperature coefficient resistivity.•Designed device layout using Matlab, MathCAD and Film wizard software.
