• Developed security feature to enable car and energy product’s ECUs only accept firmware update from Tesla, which prevents cyber-attack and IP theft exposure on millions of microcontrollers.• Updated and maintained car’s computer BIOS firmware (Coreboot Software), include enable booting from multiple SPI ROM vendors, dynamically detect and configure devices, which enable company to have multiple options in sourcing new vendors while still support backward compatibility for old device. • Experienced with debugging car’s ECUs using UDS protocol, CAN trace, IDE for microcontroller such as CCStudio, Eclipse. • Utilized logic analyzer to develop and improve JTAG emulator on microcontrollers using state machine, which helps update Tesla’s FPGA remotely via JTAG interface.

• Developed python validation testing package for all car models media control unit (car’s computer), which test all sub modules of the computer such as CPU, dGPU, DDR, NVMe.• Used a variety of benchmarking tools such as stress-ng, memtesters, FIO to stress test the sub modules of car’s computers, which helps de-risk new product in the development phrase as well as narrow down problem in the existing product.• Wrote small software packages to help deploy/flash new boards, which accelerates the bring-up process.• Engaged in every process from develop, bring-up, test, debug car’s computer.• Designed test board schematic using Altium and Cadence tools, which save $30 per car’s computer in production.

• Implemented hardware abstraction layer for microcontroller’s peripherals, also ported freeRTOS to run on this chip, which includes modifying process scheduler, and managing memory.https://github.com/Purdue-SoCET/FreeRTOS/commits?author=ttntinn• Designed UART interface and wrote firmware/driver for UART module using Verilog and embedded C.• Improved and verified timer module for RISC-V CPU core microprocessor.

Linear Circuit Course• Lead and monitor office hours for 9 teams (36 students) weekly to increase students GPA• Developed approaches and strategy to solve homework problems

• Wrote software to do direct mesh manipulation to emulate surface roughness in nanoscale optical systemso Upgraded and used opensource package roughmesh to generate meshes with accurate autocorrelation and rms roughnesso Utilized object-oriented programs and GMSH, PythonOCC/Open Cascade 3D CAD library for mesh manipulationo Presented at COMSOL 2020 Conferenceo Submitted to International Conference: SPIE Optics and Photonics 2021o Incorporated into DARPA project to be presented at SPIE Defense + Commercial Sensing Conference

• Built an open-source package and documentation for Automated optimized and tracked layout of micro/nanodevices using GDSPY (GDSII)o Used Sphinx to generate automated documentationo Used gdspy – micro/nanofabrication python CAD packageo Package published under GPLv3 for public distributiono Submitted to SPIE Optics and Photonics 2021, Paper Manuscript in preparation

• Contributed to NEW RECORD deliveried packages per day.• Utilized Amazon back-end database to monitored and corrected live information regarding 30000+ of packages, 200+ staging areas corresponding to 8 delivery companies to maximize delivery rate• Pin-pointed errors either from humans or software and took corrective action to minimize the risk of wrong delivery and delay

• Built and maintained facilities such as wooden cabins, dining hall, meeting room using a variety of mechanical tools• Diagnosed and fixed broken appliances and camp’s properties such as canoe, both mechanical and electrical issues, to ensure safety for hundreds of kids

• Observed and monitored information from hundreds of students a day to increase students GPA. • Developed solving strategy to solve a problem as people have different ways to understand a problem• Communicated information and ideas in speaking so others will understand.

• Generated programs to calculate revenue by setting up functions on Excel and C• Processed information and data to develop marketing strategy• Collaborated with a designer from Parodise company to make the page’s logo

• Greeted and welcomed customer.• Simultaneously making beverage, communicating with customers and making payments.• Arranged furniture and set up tables.• Remembered special orders. • Mastered my ability to estimate measurements.• Listening to thousands of stories from thousands of people.
