C / Systems

• Designed and implemented a shell handling concurrent jobs and async signals under strict memory constraints.
• Engineered custom memory tracking to ensure zero leaks across complex fork/exec stress tests.

C++ / ROS2

• Architected a navigation stack reducing localization drift over 10-minute high-frequency runs.
• Developed high-throughput C++ sensor drivers with sub-millisecond interrupt latency for real-time IMU fusion.

Embedded C / ARM

• Built a preemptive scheduler optimized for context switching overhead of <5µs on ARM Cortex-M.

Feb 2026

Through this project, I realized that C isn't just a programming language; it’s a direct bridge to the heart of the operating system.

Jan 2026

Implementing high-frequency IMU fusion with EKF to maintain sub-centimeter accuracy in mobile robots.

ROS2 Developer (Internship) | KarthiKesh Robotics Private Limited July — Aug 2025

• Optimized industrial sensor firmware, achieving a 20% reduction in power consumption through peripheral power-gating.
• Resolved race conditions in multi-threaded RTOS environments using JTAG and logic analysis.
