Systems Engineer & Embedded Specialist Architecting low-latency, memory-safe systems at the hardware-software interface.
I am a Computer Science undergraduate specializing in Systems Programming, Embedded Linux, and High-Performance Computing. My philosophy prioritizes rigorous memory management, cache locality, and zero-cost abstractions. I am currently focused on optimizing application-layer logic for bare-metal and kernel-space environments.

System Simulation & Architecture
- Objective: Architected a cycle-accurate RISC-V CPU simulator in C++17.
- Mechanism: Modeled a 5-stage pipeline with software-defined hazard detection and custom ISA extensions (LNZ/ZMUL).
- Metric: Achieved 3.01x speedup on sparse matrix workloads via architectural optimization.
- Stack: C++17, RISC-V ASM, CMake
Systems Security & FUSE
- Objective: High-performance user-space ransomware detection system.
- Mechanism: Real-time Deep Content Inspection (LibMagic) and Entropy Analysis to detect encryption.
- Metric: 11x Performance Gain achieved by rewriting core logic from Python to C; < 7MB Memory Footprint.
- Stack: C (libfuse3), Linux API
OS Development
- Objective: Custom Linux OS build for legacy x86 hardware.
- Mechanism: Replaced glibc with musl, implemented BusyBox, and stripped RootFS.
- Metric: Reduced OS footprint to < 50MB with sub-second boot times.
- Stack: Buildroot, Linux Kernel v6.x, BusyBox
