About Me

I'm a passionate software engineering student at Iowa State University, with hands-on experience spanning full-stack development, cloud infrastructure, and cybersecurity. I'm currently working on the Cloud Security Posture Management (CSPM) team at John Deere, where I focus on securing AWS environments and implementing compliance frameworks.

Outside of work and school, I enjoy running homelab projects on my Raspberry Pi—from self-hosted NAS and monitoring stacks to game servers—and contributing to open-source projects. I believe in learning by building, and I'm always looking for the next problem to solve.

I hold the Microsoft Azure Fundamentals (AZ-900) certification and am currently pursuing the AWS Certified Cloud Practitioner, AWS Certified SysOps Administrator, and AWS Certified Developer – Associate.

Projects

Grade Predictor

AI / Full-Stack Web App

An AI-powered academic tool that helps students track grades, predict final course outcomes, and calculate what scores they need on remaining work to hit a target grade — all with local LLM inference so no personal data ever leaves the machine.

Parses PDF/TXT syllabi using a local Ollama (llama3.2) model to extract grading policies, drop rules, and category weights.
Interactive what-if analyzer and scenario engine (best-case, worst-case, current-pace) built with Chart.js for visualization.
Flask backend with a single-page frontend; all AI inference runs locally via Ollama — no grades or documents sent externally.

Course Connect

Android App

A Spring Boot-based social media style Android app enabling Iowa State students to rate courses, view peer comments, and generate an overall difficulty score for their schedules.

Served as backend developer; designed RESTful APIs for rating aggregation and comment retrieval.
Implemented difficulty-based course filtering with MySQL via MySQL Workbench.
Collaborated via Git following Scrum/Agile workflows including sprint planning and code reviews.

CyEval

Web Tool

A web-based academic performance visualization tool that lets users upload CSV/Excel files and explore their grades through interactive charts and breakdowns.

Supports CSV and Excel file uploads with client-side parsing.
Renders dynamic, interactive charts for grade analysis over time.
Built with vanilla JavaScript, HTML, and CSS—no backend required.

Raspberry Pi Home NAS

Homelab Infrastructure

Self-hosted network-attached storage solution built on a Raspberry Pi 5, with a full Docker stack, WireGuard VPN access, and system monitoring.

Deployed and configured Docker containers for network storage services.
Set up WireGuard VPN for secure remote access to home network.
