Esdras Caleb Full Stack Developer

My Expertise

I'm a Full Stack Developer and Game Programmer from Brazil

Code Stack

I’ve been working with web development since 2008, building solutions across frontend and backend. My main programming languages are PHP and JavaScript, with strong familiarity in TypeScript, Python, HTML, CSS, SCSS, SQL, and JSON. I also have experience with Java, C#, C, XSLT, Lua, and NCL, allowing me to work comfortably across different platforms and architectures.

Frameworks

I work across web, game development, content management, and machine learning. In web, I use Laravel, React, jQuery, Bootstrap, and Node.js, with strong experience customizing Moodle and WordPress. I also use OAuth for secure system integration. In games, I work with Unity, Godot, and Defold for cross-platform 2D/3D development. For machine learning, I use LLMs with Hugging Face, llama.cpp, and TensorFlow. This versatile stack lets me adapt quickly and choose the right tools for each project.

DevOps

I manage Linux (CentOS, Fedora, Ubuntu, Debian, Manjaro), Windows, and macOS systems. My DevOps skills include Apache, Nginx, Docker, and Git with GitHub/GitLab, including CI/CD pipelines. I work with MySQL, PostgreSQL, Adminer, MinIO, and CapRover. In networking, I handle LAN/WLAN, enterprise Wi-Fi with RADIUS (e.g., eduroam), DHCP, and system-wide authentication. I also use NX NoMachine and OpenVNC for secure VPN access and remote administration.
