WELCOME TO MY GITHUB! 😼🐈

Software Engineer since 2019, passionate about understanding systems by rebuilding them from scratch.
I love reinventing the wheel, not for novelty, but for mastery.
Obsessively curious about how things work under the hood: memory, networking and protocols, database engines, operating systems, coroutines, I/O, async and real-time architectures, etc.
Terminal citizen, I rarely leave it. My daily environment is a finely tuned Linux setup powered by a fleet of CLI tools crafted for speed, productivity, and minimalism. NeoVim btw.
Technical books reader, and author of technical deep-dives on Medium to share what I learn.
Committed to code quality, performance, and clarity, experienced enough to write code that’s as elegant as it is efficient.

I enjoy writing code across paradigms and ecosystems. My stack includes but is not limited to:

Java & Kotlin : Networking, My JVM HTTP Client zhttp, Backend Services, RESTful APIs, Asynchronous (CPU-Intensive) Systems, Coroutines, Android apps.
C & C++ : Low-Level System Programming, My Heap Memory Manager zhmm, My Linux Shell zshell, My Garbage Collector, CLI tools, Data Structures and Algorithms.
Go (Golang) : Low-Level System Programming, Networking, My HTTP Server zttp, Database Engines/ORMs, Backend Services, RESTful APIs, Asynchronous (Concurrent) Systems, CLI Tools, Particle Systems and Game Engines.
Rust : Low-Level System Programming, My Java Virtual Machine zvm, Networking, Backend Services, Asynchronous (Concurrent) Systems, CLI Tools, Particle Systems.
JavaScript (Node.js) : Backend Services, RESTful APIs, Asynchronous (I/O) Systems, Integrations, Web Apps.
Python : Backend Services, RESTful APIs, Scripting, Prototyping, Automation.
Lua : My Personal Neovim Configs zvim and Tooling.
Bash : Scripting, Automation, Linux Tooling.

I'm not just good at it, I already created it before :)

Java Virtual Machine (JVM) Implementation in Rust : an educational, single-threaded, garbage-collected, zero-dependency implementation of the official JVM specifications.
TCP Socket HTTP Engine & Backend Framework in GoLang : routing, middleware, HTTP/1.1 parsing, cookies, cache-control, static file serving, keep-alive requests, connection management starting from raw TCP sockets, and other standard backend frameworks features.
JVM HTTP Client (targets all JVM Projects: Android, Spring Boot, Console, etc.) in Kotlin : manually handling generic requests, HTTP/1.1 parsing, and concurrency modeling running on all JVM projects (Spring Boot, Android, Console, etc.).
HMM (Heap Memory Manager) in C : malloc/free/calloc/realloc using a virtual heap mimicking the libc memory model.
Custom Unix Shell in C : with piping, in/out/err redirections, custom commands, and built-ins.
Custom Coroutines Model : building my own coroutines concurrency api model to suspend a function and resume it later in the future.
My Own Neovim Config in Lua : built from scratch using Lua, tuned for productivity and aesthetics.
