📌 About Me

I am a systems-focused engineer specializing in low-level C++, real-time embedded firmware, KiCad PCB design, and deterministic robotics navigation.

⚡ Upstream Open Source: Active contributor across premier infrastructure codebases — cURL (curl/curl), FreeRTOS (FreeRTOS/FreeRTOS-Kernel), Espressif Systems (arduino-esp32), The Algorithms (TheAlgorithms/C-Plus-Plus, TheAlgorithms/Python), NVIDIA (cuda-samples), Arduino Foundation (ArduinoCore-API), and OpenCV Foundation (opencv/opencv).
🏎️ Autonomous Robotics & Control: Real-time pathfinding algorithms, dynamic potential fields, continuous-curvature kinematics, and deterministic sensor fusion.
🔭 Core Specialties: Interrupt Service Routines (ISRs), FreeRTOS multi-core SMP concurrency, peripheral drivers (I2C/SPI/UART/RMII/CAN/TWAI), and low-level memory safety.

🚀 Upstream Open Source Contributions

Organization / Repo	Pull Request	Technical Impact
cURL `curl/curl` 37.5k ★	PR #23850 `fix(hsts): store CURLOPT_HSTS_CTRL flags`	Resolved defect where `CURLHSTS_READONLYFILE` was ignored by persisting option bitmasks to cache instances and handle duplicates, preventing read-only HSTS cache files from being overwritten on cleanup. Extended `tests/unit/unit1660.c`.
The Algorithms `TheAlgorithms/C-Plus-Plus` 31.1k ★	PR #3268 `feat(cpu_scheduling): Round Robin scheduling`	Engineered modern C++17 preemptive Round Robin CPU scheduling engine with cyclic time-quantum preemption, Gantt timeline tracking, and mathematical invariant self-testing.
The Algorithms `TheAlgorithms/Python` 190k ★	PR #15361 `sorts: make tree_sort accept any Comparable`	Upgraded `tree_sort` and `Node` dataclass to sort arbitrary `Comparable` items using PEP 695 generic type parameters (`[T: Comparable]`).
FreeRTOS (AWS) `FreeRTOS/FreeRTOS-Kernel` 18.6k ★	PR #1535 `fix(tasks): idle task affinity default in SMP`	Resolved multi-core scheduler hang and infinite yield loops by ensuring idle tasks explicitly default to `tskNO_AFFINITY` when `configIDLE_AFFINITY` is 0, preventing idle tasks from inheriting restricted task affinities.
Espressif Systems `espressif/arduino-esp32` 14.5k ★	PR #13092 `fix(network): lock TCPIP core in hostByName`	Resolved critical lwIP concurrency kernel abort (assert in `udp_new_ip_type`) by enforcing TCPIP core locking around `dns_clear_cache()` during network reconnects.
Espressif Systems `espressif/arduino-esp32` 14.5k ★	PR #12931 `fix(zigbee): zero-init report_attr_cmd`	Fixed uninitialized stack memory defect across 12 C++ Zigbee endpoint classes (`ZigbeeAnalog`, `ZigbeeTempSensor`), enforcing standard manufacturer code assignment.
Espressif Systems `espressif/arduino-esp32` 14.5k ★	PR #12911 `feat(timer): std::function callbacks`	Engineered modern C++ lambda callback support for `timerAttachInterrupt()`, resolving ISR use-after-free race conditions across ESP32-S3/C6/P4.
Espressif Systems `espressif/arduino-esp32` 14.5k ★	PR #12908 `fix(periman): correct ETHERNET_MCD typo`	Aligned Peripheral Manager (`periman`) and Ethernet HAL with IEEE 802.3 Ethernet Management Data Clock (MDC) standard, providing 100% backward-compatible enum aliasing.
NVIDIA `NVIDIA/cuda-samples` 6.4k ★	PR #462 `fix(test-runner): executable discovery on Win32`	Resolved `[WinError 2]` path execution failures in `run_tests.py` on Windows by implementing cross-platform path separators and `.exe` binary filtering.
Arduino Foundation `arduino/ArduinoCore-API` 1.2k ★	PR #284 `feat(CanMsg): RTR frame support`	Implemented SocketCAN-compliant bit-30 Remote Transmission Request (RTR) arbitration handling, accessors (`isRtr()`, `isRemote()`), and Catch2 test suite across the official Arduino CAN abstraction layer.
Arduino Foundation `arduino/ArduinoCore-API` 1.2k ★	PR #282 `fix(IPAddress): IPv6 tautology`	Optimized core C++ IPv6 parsing logic by removing tautological bounds checks in `fromString6()`.
OpenCV Foundation `opencv/opencv` 79.5k ★	PR #29978 `doc(js): fix opencv.js URLs`	Resolved precompiled WebAssembly distribution endpoints across official OpenCV 4.x/5.x documentation pipelines.
