    jpairetti/README.md

    Hi, I'm Joaquín

    CS student at FAMAF (Universidad Nacional de Córdoba). This portfolio spans projects from kernel-level concurrency to network protocol design and REST APIs — most developed as group coursework, with my individual contribution documented in each repo's README.

    Featured Projects

    Operating Systems

    • MyBash — Unix shell implementation in C, with pipes, I/O redirection, and background execution. Includes a demo video.
    • xv6 Kernel Concurrency — Kernel-level named semaphores (sem_open/up/down/close) in xv6-riscv, using spinlocks and sleep/wakeup.
    • FAT32 FUSE Filesystem ⭐ — A FAT32 filesystem in userspace (FUSE), extended with hidden activity logging via an orphan FAT cluster technique, plus unlink/rmdir support.

    Networks & Distributed Systems

    • hget — HTTP/1.0 client built from raw sockets, with a from-scratch DNS resolver over UDP (RFC 1035).
    • Game Backlog API ⭐ — Flask REST API for tracking a video game wishlist, integrated with Wikidata, with token-based authentication and automated test coverage.
    • HFTP over Tor — Custom file-transfer protocol over raw TCP (base64 and binary framing modes), deployed as a Tor hidden service.
    • TCP Congestion Control Simulation — OMNeT++ simulation of flow vs. congestion control, implementing a TCP-inspired sliding window algorithm (rwnd/cwnd, AIMD).
    • Shortest-Path Routing for Ring Networks ⭐ — Custom routing algorithm with dynamic neighbor discovery (HELLO packets), ~87% latency improvement over the baseline. Includes a full research paper and poster.

              Hi, I'm Joaquín
              CS student at FAMAF (Universidad Nacional de Córdoba). This portfolio spans projects from kernel-level
concurrency to network protocol design and REST APIs — most developed as group
coursework, with my individual contribution documented in each repo's README.
              Featured Projects
              Operating Systems
              • MyBash — Unix shell implementation in C, with pipes, I/O redirection, and background execution. Includes a demo video.
              • xv6 Kernel Concurrency — Kernel-level named semaphores (sem_open/up/down/close) in xv6-riscv, using spinlocks and sleep/wakeup.
              • FAT32 FUSE Filesystem ⭐ — A FAT32 filesystem in userspace (FUSE), extended with hidden activity logging via an orphan FAT cluster technique, plus unlink/rmdir support.
              Networks & Distributed Systems
              • hget — HTTP/1.0 client built from raw sockets, with a from-scratch DNS resolver over UDP (RFC 1035).
              • Game Backlog API ⭐ — Flask REST API for tracking a video game wishlist, integrated with Wikidata, with token-based authentication and automated test coverage.
              • HFTP over Tor — Custom file-transfer protocol over raw TCP (base64 and binary framing modes), deployed as a Tor hidden service.
              • TCP Congestion Control Simulation — OMNeT++ simulation of flow vs. congestion control, implementing a TCP-inspired sliding window algorithm (rwnd/cwnd, AIMD).
              • Shortest-Path Routing for Ring Networks ⭐ — Custom routing algorithm with dynamic neighbor discovery (HELLO packets), ~87% latency improvement over the baseline. Includes a full research paper and poster.
