Systems Programmer | x86_64 Assembly & Low-Level C Specialist

Location: The South

I'm a low-level developer focused on x86_64 assembly and performance-critical C for Linux systems. My projects are useful for embedded, firmware, kernel, or optimization work.

• x86_64 Assembly Language (NASM): Deep knowledge of the System V AMD64 ABI, registers, calling conventions, stack management, and optimization techniques.
• Low-Level C: Building shared libraries, custom data structures, recursive algorithms, and memory-safe code (Valgrind-clean).
• Data Structures & Algorithms: Pure assembly implementations of balanced trees, dynamic structures, and utilities.
• Systems Programming: Dependency-free designs ideal for constrained environments—no external libs (with exception of libc).
• Proven memory safety and correctness in complex, recursive code.

Lightweight Client-Server RDBMS in C/C++14 (Linux)

• Bash, C, C++14, Make, AutoTools, Linux Service Setup, Sockets, MultiThreading, Synchronization, NCurses
• Persistent B+Tree Storage Engine, Persistent JSON Schema, SQL Recursive-Descent Lexer/Parser/Compiler, Byte-Code Virtual Machine
• SQL Data Definition Language (DDL), SQL Data Manipulation Language (DML), SQL Joins (INNER, LEFT, RIGHT)
• Encrypted Authentication, System Privileges (global server actions), Object Privileges (access to specific database structures)
• LOAD INFILE (high speed loading of CSV data), SOURCE (execute SQL script files)
• Dependencies: libc, ncurses readline, glib-2.0, json-glib-1.0, libgcrypt-1.6.1 or later
