// Two crafts, one obsession: systems that think, and worlds that breathe.
// From zero to deployed -- backends, frontends, AI integrations, and everything in between.
// If it thinks, automates, or integrates -- I'm the one building it.

AetherTable – AI Dungeon Master
Play tabletop RPGs with an AI game master that narrates, remembers the campaign, and rolls real dice. Open source, bring-your-own-key.
- Multi-provider – Gemini, OpenAI, Ollama or LM Studio behind one interface; runs fully local if you want it to.
- Persistent saga memory – rolling summarization folds old turns into long-term memory so campaigns survive context limits.
- Voice mode – speech in, narrated speech out, over a WebSocket stream.
- Real dice – the model emits
[[ROLL:1d20+5]]tags resolved by code, so it can never invent a number.

MTG Stock Market – Arcane Exchange
Full-stack Magic: The Gathering card price tracker – think Bloomberg Terminal, but for cardboard.
- Backend – FastAPI + SQLAlchemy + SQLite. JWT auth, freemium roles, price history, news scraping, ML-based 7-day price predictions via scikit-learn.
- Frontend – React + TypeScript dashboard: trending cards, portfolio tracker, price alerts, community comments, Pro-only AI recommendations engine.
- Infra – Fully Dockerized (per-service Dockerfiles + docker-compose). PWA-ready with Workbox service worker.

Windows Back Catalog – Every Windows ISO, Back in the Dropdown
Microsoft still hosts the ISO for every Windows release it ever shipped. The download page just stopped listing them. This puts them back.
- One console snippet, or a bookmarklet, rewrites the edition dropdown on Microsoft’s own download page with the product-edition IDs it quietly stopped listing.
- Windows 7 SP1, 8.1, 10 22H2 and Windows 11 24H2/25H2 in x64 and Arm64, straight from Microsoft’s CDN: no third-party mirror, no torrent, no bundled “activator”.
- Not a downloader and not a bypass – it only repopulates a
<select>and fires achangeevent; Microsoft’s own flow issues the signed link. - Documents what will bite you: VPN and datacenter IPs get refused, links expire in 24 hours, and an ISO is still not a licence.

MoneyControl – Personal & Business Finance
Mission control for money: personal budgets, savings goals and business invoicing in one dark-first cockpit.
- Accounts, transactions, budgets, goals and recurring expenses, split across personal and business scopes.
- Client directory, invoicing and line items for the freelance side of the ledger.
- Shared single sign-on with the rest of the platform; every query scoped by owner.

Dopamine – Shopping Simulator
The experience of online shopping, without spending real money.
- Thousands of real products across four parody marketplace skins, with a full cart and “checkout” flow.
- Hard safety invariant – no payments, no personal data, no real purchases, enforced by a
connect-src 'self'CSP that blocks every off-origin request at the browser level. - Offline-capable: ships with a bundled catalog seed and needs no external API to run.

Link Shortener & QR Generator – Free, No Account
Paste a URL, get a short link and its QR code in one step. No account, no ads, no tracking pixels.
- Custom aliases, click counts, and a delete token that is the only proof of ownership (no accounts to breach).
- Generated share cards name the real destination, because a shortener that hides where it goes is a phishing tool.
- Rejects every scheme but
http/https, rate limited per address.
