Metrify

[IOS] [ANDROID] [AGENTIC AI] [RAG]

A full-stack iOS and Android fitness app I founded and build solo. It pairs a chat interface with the tracking accuracy and persistence of a traditional fitness tracker — an agentic AI coach logs food, exercise, and weight through natural conversation, using RAG over a vectorized nutrition database and deterministic tool calls so entries actually land correctly. Currently in internal beta with about 30 testers.

JustAnAI

[FASTAPI] [RAG] [OPENAI] [DOCKER]

RAG-powered personal portfolio chatbot. You're talking to it right now. Built with FastAPI, SQLite, sentence-transformers embeddings, and OpenAI. The chatbot retrieves relevant chunks from a vectorized knowledge base about my background and projects, and answers recruiter and interviewer questions in real time.

03 · DEEP LEARNING

Keystroke Synthesizer

[PYTORCH] [DEBERTA-V3] [TRANSFORMERS]

A deep learning model that learns individual human typing behaviors and generates synthetic keystroke dynamics from any text input. Uses a DeBERTa-v3 transformer with heteroscedastic regression to predict dwell time, flight time, and typing speed per character — with calibrated uncertainty. Try the live demo in the Keystroke Sandbox.

ReGen

[PYTHON] [LLMS] [QUARTO]

Automated document intelligence pipeline. Feed it URLs, PDFs, Word docs, CSVs, or Excel files — it extracts structured data via LLM map-reduce, clusters sources by topic, synthesizes cross-source findings, and generates polished reports rendered with Quarto. Built with collaborator Ben Warring.

AutoVideoProducer

[JAVA] [OPENAI API] [FFMPEG] [REMOTION]

Fully automated multi-channel YouTube Shorts pipeline. GPT-4o scrapes trending stories, OpenAI TTS narrates them, Whisper generates word-timed captions, FFmpeg trims gameplay backgrounds, and Remotion renders 1080×1920 MP4s — all uploaded to five YouTube channels on a 5-hour rolling schedule. Built June 2025.

AIECODE

[SQL] [NODE.JS] [REST APIS]

Agile project management platform focused on education and students. I redesigned the SQL schema and moved arithmetic into SQL views for a substantial speed improvement, maintain the production database serving 100+ users, and built REST API endpoints for AIE5 — the next iteration of the platform.

Battle for Rome 2

[PYTHON] [PYGAME]

A fully-playable 2D side-scrolling action game I built in Python with Pygame during my sophomore year of high school — before any formal CS coursework. Multi-phase boss fights (Julius Caesar, Cleopatra), melee and ranged combat, platforming physics, and parallax backgrounds. Preserved as-is to show where I started.
