Multi-service scam-detection platform for job postings. A React frontend routes through a Node.js gateway to two specialized backends: a Quarkus/Java service for WHOIS domain-age lookups and a FastAPI service that streams LLM analysis via a local Ollama instance on a Jetson Orin Nano. Flags suspicious postings in seconds using domain age, linguistic red flags, and recruiter patterns.

Personal wellness tracking app where users log symptoms, moods, sleep, and daily habits. A FastAPI backend aggregates the entries and sends them to a locally-hosted LLM (Ollama on Jetson Orin Nano) to generate personalized pattern insights — no data ever leaves the home lab.

Personal finance dashboard with a composite PulseScore (1–10) built from RSI, MACD, EMA crossovers, Bollinger Bands, options flow, insider activity, and earnings proximity. Tracks watchlist stocks with intraday snapshots, 7/30/90-day verdict accuracy tracking, a paper trading ledger, AI-powered chat analysis, and real-time WebSocket announcements. Fully self-hosted on Kubernetes.

Makes IETF RFCs easier to read: enter an RFC number or search by title and get plain-language section summaries, ASCII-art diagrams re-rendered as real Mermaid diagrams, and a glossary of key terms alongside the original text. Processed on demand via a local Ollama LLM and cached in SQLite.

Study site for the CompTIA Security+ SY0-701 exam: notes broken down per exam objective with a quiz at the end of every section, whole-domain quizzes, timed 90-question mock exams weighted like the real test, acronym flashcards, and dense cheat sheets.
