08.2021 - 03.2025

Firmware & Algorithm Development: Designed and implemented power-efficient, fixed-point algorithms in C for UWB ICs based on IEEE 802.15.4a/4z standards, including synchronization, CFO correction, STS, SRC, and payload processing modules.
DSP Block Verification: Developed and verified fixed-point implementations of core DSP blocks, including CORDIC-based trigonometric functions (sine, cosine, arctangent) to ensure accuracy, stability, and efficient hardware mapping.
Development Environment: Utilized Visual Studio Code extensively for C code development and advanced debugging; collaborated with firmware teams during system-level firmware debugging and performance validation on hardware platforms.
Version Control and Collaboration: Managed source control and code integration workflows using Git and SVN, ensuring traceability and collaborative development across algorithm, firmware, and verification teams.
Firmware Debugging and Validation: Assisted the firmware team in debugging embedded firmware flashed onto UWB ICs; supported system integration testing, fault isolation, and firmware-hardware co-verification.
ATE Validation and Hardware Testing: Conducted chipset validation using LitePoint (IQfact+) test equipment and Rohde & Schwarz signal generators; validated firmware-driven performance on Automated Test Equipment (ATE).
Cross-Functional Integration: Worked with SoC and RTL verification teams using UVM methodologies; gained hands-on exposure to Verilog, VHDL, and Perl scripting for simulation and debugging support.
Research and Optimization: Researched trade-offs between fixed-point and floating-point implementations to optimize power efficiency and computational complexity for hardware implementation.
Certification and Test Automation: Developed Python-based test benches using Pytest to automate FiRa certification workflows, supporting successful certification of UWB chip designs.
Technical Documentation: Authored detailed design specifications, technical reports, and customer-facing documents to support design traceability and compliance.
Mentorship and Team Contribution: Provided technical mentorship to newer team members and contributed to cross-functional design reviews to ensure overall product quality and robustness.
