Hello world. I'm
First-year cybersecurity student based in Tokyo, Japan
01 / about
I'm a first-year Cybersecurity student at Temple University Japan, based in Tokyo. I got into coding out of curiosity and found I genuinely love it I've worked through Python, C, Java, and web development as part of my degree. My biggest interests right now are cybersecurity and digital privacy, network security, operating systems, and AI and machine learning.
I've already had the chance to build a real-world project and place first in a hackathon, and I'm eager to keep growing. I'm looking for opportunities to collaborate, contribute, and learn alongside people who hold themselves to a high standard and push each other to be better.

Designed and coded from scratch to practice modern HTML, CSS, and vanilla JavaScript, with animations, responsive layout, and all. A project that's also the thing showing you the project.
A business website built for a freelance English teacher to advertise their services. Features a clean landing page, a services section, and a contact form. My first project built for a real client.
Temple University Japan — Tokyo, Japan
Competed with a team in a UI/UX-focused hackathon hosted by Temple University Japan. Our team took first place by designing and prototyping a clean, user-centered interface concept under a tight time constraint.
Shibuya, Tokyo, Japan
Built TabeTalk, an AI-powered dining app that removes the chaos of splitting restaurant bills. Guests sign in, provide a voice sample, and the app listens in real time during ordering to identify who ordered each item. When the check arrives, the host scans the bill, costs are assigned automatically, and everyone pays their share hands-free.

Used multiple programming languages and several API keys to integrate voice and payment workflows.
Open Network Labs, Lovable, Supercell, VoiceOS, RevenueCat, and ElevenLabs.
Fully developed by a crew of students from Temple University Japan.
Shibaura Institute of Technology — Tokyo, Japan
Built FocusHear in 48 hours, a real-time assistive communication platform tackling SDG 10: Reduced Inequalities. The core insight: 430 million people worldwide live with disabling hearing loss, yet no existing technology gives them the ability to choose whose voice they hear in a crowded room. Every captioning app today transcribes everyone simultaneously, flooding users with an unreadable wall of overlapping voices. We built something different.

Selective Listening (tap a face, hear only that person via ElevenLabs Scribe + lip movement detection), Sign Language Bridge (ASL fingerspelling via hand position tracking), and Chat Mode (voice-enrolled speaker diarization with color-coded live log).
ElevenLabs (Scribe transcription + speaker diarization), real-time lip movement detection, hand position tracking for sign language recognition.
Tokyo Student Network, Tokyo AI (TAI), TUJ CS Society, GDG on Campus at Sophia, IPUT, and Waseda University.
Hongo, Tokyo, Japan
Brought a massively rebuilt FocusHear to an invite-only "Build with OpenAI" event hosted by OpenAI and Tokyo AI. Since the original SDGs to Startups prototype, the app went through a full architecture rebuild: a GPT-4o + ElevenLabs Scribe AI pipeline, Supabase Auth with Stripe billing, saved voice and face profiles with automatic in-session recognition, a sound-alert and live-translation system, and a real ONNX-based LSTM sign-language model replacing the original demo classifier. Competed against strong international teams and advanced to the first round.

Vertical Slice Architecture rebuild, GPT-4o + ElevenLabs Scribe AI pipeline, Supabase Auth (email/password + Google OAuth) with Stripe Pro billing, saved voice and face profile recognition, sound-alert system with tone/intent badges and multilingual live caption translation, and a trained ONNX-based LSTM sign-language model.
Advanced to the first round against a strong field of international teams.

04 / my background
Lake Minneola High School — Minneola, Florida, USA
Completed a standard high school curriculum at Lake Minneola High School with coursework across core academic disciplines. Built foundational skills in mathematics, English, and the sciences while developing the study habits and work ethic that carry into everything since.
0842 — Field Artillery Radar Operator | Camp Hansen, Okinawa, Japan & Camp Lejeune, North Carolina, USA
Served four years as a Field Artillery Radar Operator, operating the AN/TPS-80 Ground/Air Task Oriented Radar, AN/TPQ-48 Lightweight Counter Mortar Radar, and AN/TPQ-46 Firefinder Radar (now retired). Worked as part of a cohesive team under demanding operational conditions and strict time constraints, contributing to the successful tracking of thousands of artillery munitions and delivering critical battlefield intelligence directly to commanders.
Concurrently held a secondary billet as a Key Management Infrastructure (KMI) Custodian, responsible for the secure handling, safeguarding, loading, and operational use of highly sensitive military cryptographic keys and associated intelligence materials.
Selected to attend two formal military schools, earning qualifications as both a Combat Marksmanship Coach (CMC) and a Combat Marksmanship Trainer (CMT). As a CMC, provided individualized coaching to improve Marines' fundamental rifle and pistol proficiency. As a CMT, operated full courses of fire, developed training curricula, and advanced modern marksmanship standards across the unit.
Temple University Japan — Tokyo, Japan
First-year coursework covering programming fundamentals in Python, C, and Java, introductory cybersecurity concepts, and core math for Cybersecurity at Temple University Japan. Learning to think like a security professional from the ground up.
