Engineered a race-free simulation of Dijkstra's Dining Philosophers using pthreads and mutex locks; built async monitoring routines with microsecond-precision timers preventing thread starvation and deadlocks.

Building a non-blocking HTTP/1.1 server using epoll I/O multiplexing, with stateful request parsing, NGINX-style config parsing, and CGI execution.

Architected a multi-container infrastructure with Docker Compose on Alpine Linux; isolated containers for NGINX (TLS/SSL), WordPress, and MariaDB with bind mounts and internal bridge networking.

Implemented a POSIX-compliant shell with an AST parser enforcing operator precedence, nested subshell forks, and quote-aware tokenization; zero leaks via Valgrind.

Engineered a Unix pipeline engine replicating shell redirection (< file1 cmd1 | cmd2 > file2) using fork, pipe, dup2, and execve; implemented POSIX process synchronization, multi-fd stream redirection, and PATH resolution.

Built a terminal-based banking and ATM system in C++ with bitmask user permissions, transaction audit logging, and file-based persistence.

Developed a 3-tier desktop application separating UI, business logic, and data access layers; used parameterized T-SQL queries to prevent SQL injection.

Built a dual-stack radix sort on array stacks with coordinate compression, bounding passes to log2(N); added lookahead bit-checking in Stack B to cut redundant transfers, with dedicated solvers for N ≤ 5.
