American Axle Metal Forming — North Vernon, IN

• Work with manufacturing engineers to troubleshoot and diagnose issues with machines on the production line.
• Write Excel scripts with LLM assistance to automate machine-data analysis, cutting turnaround on production-line issues.
• Serve as sole on-site IT: administer and deploy all plant computers, and provide tier-1/2 support for plant hardware (workstations, printers, cameras).

• Developed full-stack features for a puzzle hunt platform using MySQL, a Node.js REST API, and Svelte, enabling teams to securely access and solve puzzles during live events.
• Designed and implemented responsive user-facing interfaces in Svelte, improving usability for puzzle navigation, puzzle tracking, and live event interaction.
• Collaborated with a four-person engineering team and coordinated with the client to refine requirements and adjust implementations based on feedback.

• Researched microkernel and monolithic kernel architectures to inform the design of a custom microkernel OS, with emphasis on process isolation, inter-process communication (IPC), and kernel responsibility boundaries.
• Performed in-depth analysis of process control block (PCB) designs in existing production-level operating systems to design and implement a PCB, weighing real-world trade-offs in scheduling, fault handling, and capability management.
• Designed and developed the in-RAM filesystem for kernel-bootstrapping programs.
• Developed the project's ELF loader based on the ELF loader specification.
• Modernized the project's build infrastructure by migrating from a Make-based system to Meson, improving maintainability and iteration speed for development.

• Designed and implemented a custom network driver and UDP network stack for the Xv6 operating system, enabling inter-machine packet transmission.
• Built support for Ethernet, ARP, and UDP, as well as packet construction/parsing.
• Implemented a socket API into Xv6, modeled after Linux sockets, supporting socket(), bind(), recvfrom(), and sendto().
• Debugged low-level networking in QEMU and with Wireshark, developing deeper understanding of protocol interactions and driver/OS boundaries.
