I earned Top 5 national placement twice in the National Cyber League (NCL), a highly competitive collegiate cybersecurity competition in capture-the-flag (CTF) format, with over 8,500 to 10,000 students competing each season. For both performances, I received a trophy recognizing my placement among the top performers nationwide. In addition, I secured first place in the 2023 Mountain West Cyber Challenge (MWCC).
VowelFreq analyzes vowel frequency hotspots in over 400,000 dictionary words to optimize word structure patterns for password cracking. By identifying high-probability vowel positions, it reduces keyspace size and improves efficiency in Hashcat attacks—especially for longer password lengths.
UAP FILES is a platform that demonstrates how artificial intelligence can be harnessed to process and summarize large volumes of audio-visual content, starting with YouTube videos. Built entirely using Python, this project begins by automatically transcribing audio from videos in a given YouTube playlist. Each transcription includes precise timestamps, making it easy to trace the summarized content back to its original moment in the video.
Once transcriptions are generated, a local AI model—optimized for contextual summarization—crafts a clear, cohesive article-style summary for each video. These summaries are not generic or robotic; they are designed to read like human-written editorial pieces, condensing the core insights of the video into a format that’s accessible, searchable, and useful.
While UAP FILES currently focuses on videos related to Unidentified Aerial Phenomena (UAP), the entire system has been designed with adaptability in mind. The same workflow can be repurposed for different subjects, use cases, or industries—whether it’s for:
With the integration of local AI, the system operates privately and efficiently without needing to rely on third-party cloud services, ensuring faster performance and better control over sensitive data.
UAP FILES is more than just a showcase—it's a proof-of-concept for how AI can transform how we interact with spoken content. The goal is to offer this as a service or tool that can be tailored for clients who need smarter, AI-powered organization and discovery for their audio or video archives.

Fanbuild (2013–2021) was an eCommerce merchandising company I founded, focused on trend-driven apparel design. Over the course of the project, I created and sold more than 1,000 original designs, each tailored to current cultural and market trends. To scale operations efficiently, I developed a robust custom backend system that automated mockup generation, streamlined order management, and introduced a unique SKU system capable of tracking style, size, design, and color variations for bulk fulfillment. The success and sustainability of Fanbuild hinged on this backend infrastructure, which became the backbone of the business and my primary technical focus throughout its operation.
