## What I Build

I specialize in the full stack of privacy-focused Web3 applications: ZK rollup frontends, on-chain event indexers (Bun + MongoDB + Fastify), cross-chain bridges, TypeScript SDKs, AI agent systems backed by TEEs, and Phaser 3 browser games. I own every layer — UI, smart-contract integration, indexers, APIs, and SDKs — across all projects I ship at Cyphronix Software.

Core expertise: Aztec Network (ZK rollup, Aztec.js, private state), Sui Move contracts, Solana Anchor/Rust contracts, EVM/Solidity, Next.js 15, TypeScript, Bun, MongoDB, Fastify, Supabase, zkPassport, Jotai, shadcn/Radix UI, Phaser 3.

## Shipped Projects

### Raven House NFT Marketplace
- Live: https://app.ravenhouse.xyz/
- A privacy-preserving NFT marketplace on Aztec Network's ZK rollup. Solo full-stack build.
- Hard part: Aztec has no hosted event indexer. Built a custom Bun + MongoDB + Fastify indexer handling 8 event types (ListingCreated, ListingCancelled, ListingSold, NFTTransfer, OfferCreated, OfferAccepted, OfferCancelled, MetadataUpdate) with parallel Promise.all processing at 14 blocks per batch.
- Stack: Next.js 15, Aztec.js, Supabase, shadcn/Radix UI, TypeScript, Bun, MongoDB, Fastify

### Raven Bridge
- Live: https://bridge.ravenhouse.xyz/
- Cross-chain bridge between Ethereum and Aztec Network, integrating zkPassport identity verification so only verified humans can bridge assets.
- Uses @ravenhouse/omni-sdk for all contract calls.
- Stack: Next.js 15, Aztec Network, @ravenhouse/omni-sdk, zkPassport, Jotai, Supabase, TypeScript

### @ravenhouse/omni-sdk
- npm: https://www.npmjs.com/package/@ravenhouse/omni-sdk
- TypeScript SDK for the Raven House ecosystem. 60+ releases, 9 sub-module exports.
- Modules: L1 contract bindings, L2 contract artifacts, Ethereum utilities, React component library, zkPassport IdentityVerifier, AzGuard wallet integration, Vite plugin, CSS/Tailwind styles, config module.
- Used by both the Raven Bridge frontend and external consumers integrating with the Aztec ecosystem.
- Stack: TypeScript, Aztec.js, Vite, React

### Red Sentinel (formerly Sui Sentinel): AI Red-Teaming Arena
- Live: https://app.suisentinel.xyz/
- Crowdsourced AI prompt-hacking arena. Users deploy AI agents with custom system prompts inside a TEE (tamper-proof). Attackers pay tokens to try to jailbreak the agent within a 14-day lock-in window.
- Fee structure: 50% prize pool, 40% agent creator, 10% protocol.
- Three contract sets: Sui Move, Solana Anchor/Rust, Solidity (EVM). Custom ML training data for jailbreak resistance. Discord bot, admin dashboard, Mintlify docs, Rive animations.
- Stack: Next.js 15, Sui Move, Solana Anchor/Rust, Solidity, Bun, MongoDB, Fastify, Rive, TypeScript

### Phaser 3 Game Prototypes
- Live: https://space-monkey-one.vercel.app/
- Browser game prototypes: Space Monkey, Space Invader, Breakout. Sprite physics, game loops, asset pipelines.
- Stack: Phaser 3, JavaScript
