Built and maintained responsive web applications within the company's internal tech stack, collaborating with designers and backend developers to ship production-ready features.

• Developed web applications using [PHP/Sass/WordPress], ensuring cross-browser compatibility and responsive design
• Collaborated with a team of 6 across design, backend, and QA to deliver features on schedule

POSIX-compliant shell written from scratch in C, replicating core bash behavior without relying on external shell libraries.

• Implemented a custom lexer/parser to tokenize and interpret commands, quotes, and expansions
• Managed child processes and inter-process communication via fork, execve, waitpid, pipe, and dup2
• Handled redirections (<, <<, >, >>) by manipulating file descriptors at the syscall level
• Built a signal-handling layer (SIGINT, SIGQUIT, SIGTERM) to match interactive bash behavior
• Developed 7 builtins (echo, cd, pwd, export, unset, env, exit) with correct exit-code propagation

Ray-casting 3D engine written in C, rendering a first-person view from a 2D grid map and letting the player navigate maze-like environments in real time.

• Implemented the ray-casting algorithm (DDA) to compute wall distances and project a 3D view from a 2D map at real-time framerate
• Wrote a custom parser for the map file format, validating layout, textures, and spawn position with granular error handling
• Applied texture mapping to wall surfaces, sampling bitmap textures per column with distance-based shading
• Handled player movement and wall collision detection using trigonometric projection and grid lookups

This is a web-based version of the eponymous board game. Built as a team of 5, the project is currently under development
