I’m a Software Engineer with experience in C++ and Java development, focused on building reliable, maintainable, and performance-oriented software.

Recently, I worked as a C++ Developer in a production environment, contributing to online real-money game systems using C++17, Linux, Protobuf-based workflows, and internal tooling systems. My work involved debugging, performance optimization, and working with large-scale codebases in collaboration with QA and engineering teams.

Before that, I worked as a Java Backend Developer, building REST APIs, maintaining backend systems, and working with Spring Boot, Hibernate, JUnit 5, and Mockito.

At 42 Barcelona, I strengthened my foundations in systems programming through low-level and infrastructure projects such as:

🌐 WebServer (C++)
HTTP server implementation handling client requests, routing, configuration parsing, and basic HTTP protocol behavior, focused on networking, concurrency, and system-level programming.

🐳 Inception (Docker / System Infrastructure)
Infrastructure project involving containerization, service orchestration, and system deployment using Docker. Focused on Linux environments, networking, and multi-service architecture.

🐚 Minishell (C)
Unix shell implementation with process management, pipes, redirections, and signal handling.

🎮 Cub3D (C++)
3D raycasting engine focused on graphics programming, memory management, and performance optimization.

• C++ (17) / C
• Linux systems programming
• Debugging (GDB, Valgrind)
• Protobuf / JSON data pipelines
• Backend development (Java, Spring Boot)
• Object-Oriented Programming (OOP)
• Memory management & performance optimization
• Networking fundamentals (HTTP, sockets)
• Docker & system infrastructure
• Git, CMake
• Agile workflows (Scrum, Kanban)

• Modern C++ and systems programming
• Linux internals, networking, and concurrency
• Backend and low-level architecture design
• Performance optimization and scalable systems

• Minishell → Unix shell built in C (processes, pipes, signals)
• Cub3D → Raycasting engine in C++ (graphics, rendering, optimization)
• WebServer → HTTP server in C++ (networking, concurrency, HTTP protocol)
• Inception → Docker-based infrastructure setup (services, networking, system orchestration)
