## Work Experience
### Senior Software QA Engineer @ Tesla
Jan 2025 – Present | Palo Alto, California, United States
UI Media Team - Validation Lead

### Software QA Engineer @ Tesla
Jan 2023 – Jan 2025 | Palo Alto, California, United States

### Software Engineer @ Ratio Finance
Jan 2022 – Jan 2022
- Developed smart contracts using Rust + Anchor (Project Serum) to allow users to earn yield on deposited collateral and mint USDr (stablecoin) on Solana
- End-to-end implementation of Admin Panel control of yield farm, allowing a superowner's wallet to create new yield farming pools, set relevant fees, pause minting of USDr, etc
- Integrated Saber yield farms with Ratio's platform, enabling users to deposit collateral into Saber's yield farming pool and mint USDr against it
- Implemented Instaswap using Raydium to allow users to directly swap for LP tokens on Ratio's platform

### Embedded Software Engineer @ Deep Trekker Inc.
Jan 2021 – Jan 2021 | Waterloo, Ontario, Canada
- Independently designed and implemented new magnetic calibration algorithm in C using least-squares sphere fitting to calculate magnetic bias values and gyro data for sample point selection, reducing calibration error by 59x
-Programmed new state translation system for Pivot ROV, reducing state interdependencies by 72% and eliminating potential race conditions
- Implemented EEPROM I2C failure handling into the Revolution ROV's primary bootloader
- Reduced pub-sub message queue overflow occurrences by 18% by improving task prioritization

### Windows Core Software Developer @ AMD
Jan 2020 – Jan 2020 | Markham, Ontario, Canada
-Refactored Radeon kernel-debug tool's code repository to make files easier to find and amended the CMake build architecture accordingly
-Implemented new commands and unit tests for the Radeon kernel-debug tool using C++ to make driver debugging easier for developers
-Added Radeon kernel-debug tool support to new areas of driver code using C++, allowing developers to easily extract new information from the live ASIC
-Wrote a C++ class to export Radeon telemetry data to MongoDB, rather than storing the parsed data in a CSV file as it was previously
-Programmed Python script to backup SQLite3 database files every 2 weeks to ensure telemetry data isn't lost when raw dumps are deleted

### Embedded Developer @ ecobee
Jan 2020 – Jan 2020 | Toronto, Canada Area
- Improved firmware for thermostat temperature slider to allow for greater degree of parameter customization, including slider sensitivity, scroll speed, and inactivity distance
- Designed and facilitated user tests with new thermostat firmware to determine most preferred combination of temperature slider parameters
- Developed solution to customer issues with slider sensitivity by designing and prototyping buttons to be used with the thermostat slider to allow for more precision when adjusting the temperature
- Programmed new QA PCB added to existing thermostat HVAC simulators using Python
- Developed numerous UI screens for new thermostat installation flow using C++ and created automated tests with Python to ensure functionality
- Created new thermostat pop-up alerts using C++ to address user experience concerns

### Embedded Test Developer @ ecobee
Jan 2019 – Jan 2019 | Toronto, Canada Area
- Independently designed and programmed a Sensor Simulator using C++ to test the functionality of the SmartSensor and the SmartSensor for Doors and Windows, enabling the automation of 50+ test cases which previously took one week of manual testing
- Used principles of Object Oriented Programming to create a virtual sensor base class which allows integration of the ecobee's different sensors into one sensor array
- Programmed Python script to parse and analyze sensor packet data to make product decisions, including how often and how far apart retry packets should be sent
- Automated 15+ thermostat integration tests using Python
- Designed integration test plan to verify functionality of production units of the SmartSensor, which was used for all customer-facing releases
- Assembled and tested the hardware for HVAC simulator circuit boards used for QA

### FIRST Robotics Team @ Robo Sapiens - Team 5699
Jan 2014 – Jan 2018 | Toronto, Canada Area
- Designed, built, coded, and tested a robot each year for FIRST Robotics regional competitions - Programmed autonomous code to interface with sensors and driver controls for robot using Java
- Worked with motors, gears, pneumatics, and conveyor belts to create systems capable of grabbing, lifting, and outputting objects
- Organized and led meetings for the team of 24 members
- Reached out to companies and obtained sponsorships totalling $3000 for the team
