Co-developed a functional IRC server supporting multiple concurrent clients with non-blocking I/O for real-time chat.

• Socket architecture with multiplexed event loop
• Protocol-aware parsing + robust connection handling
• Focus on correctness, latency, and clean state management

Designed and deployed a multi-container stack: Nginx (TLS), WordPress (PHP-FPM), and MariaDB with networks, volumes, and automation.

• Secure networking + persistent storage via volumes
• Reproducible orchestration with Docker Compose
• Operational mindset: configs, hardening, deploy flow

Built a ray tracing engine from scratch: intersections, lighting, shadows, and scene parsing to render realistic 3D images without external graphics libraries.

• Ray-object intersections + camera transforms
• Scene parsing + stable rendering pipeline
• Attention to correctness and visual quality

Implemented a Bash-like shell: command parsing, pipelines, redirections, heredocs, built-ins, and env handling with careful memory management.

• Lexer/parser-driven execution model
• File descriptor discipline and error handling
• Valgrind-first mindset to avoid leaks
