Deep Dive Into the Machine

Bridging hardware architecture with resilient software engineering.

I'm a software engineer with a relish for low-level languages and systems programming. I thrive on diving deep into the intricacies of code, optimizing performance, and understanding precisely how hardware and software interact.

My journey has led me to explore languages like C, C++, and Assembly, where I’ve honed rigorous skills in memory management, complex data structures, algorithm design, and efficient problem-solving. Understanding how CPUs execute instructions and being able to read compiler-generated assembly is both fun and essential to my engineering mindset.

I’m constantly exploring new frontiers: whether it's experimenting with microcontrollers, developing lightweight operating system kernels, analyzing compiler design, or constructing secure backend APIs.

Systems Programming

C, C++, Assembly, explicit memory management, pointer arithmetic, and CPU cycle optimization.

OS Internals & Kernel

Developing lightweight OS kernels, context switching, interrupt descriptors (IDT), and memory paging.

Backend Architecture
