Blockchain Engineer · Sui Move · Rust · Web3 Infrastructure
I build protocol-level infrastructure for Web3. Most of my work lives at the intersection of distributed systems, cryptography, and developer tooling things that other builders depend on to ship their own products. I've also built consumer-facing products: wallets, payments, and onchain applications used by real people.
Currently deep in ZK, Privacy, AI, and Substrate - learning how blockchains are built from the inside out.
- Waldrop -> move files from any Web2 storage (S3, Dropbox, Drive) to Walrus on Sui.
- Fomly -> decentralized alternative to Typeform.
- KisanSteer — GPS guidance for tractors. Arduino firmware + Rust edge server + Next.js. Field data stored on Sui via Move contracts. Built from watching farmers navigate fields by hand.
-
SuiLearn - developer infrastructure for the Sui ecosystem. Used by devs across the network
- gRPC Playground - explore every gRPC method interactively
- RPC Playground — REST API sandbox
- Faucet — testnet tokens, no friction
- Transaction Explorer — on-chain tx viewer
- Wallet Utility — wallet creation tools
-
Nimora — a Sui wallet built around passkeys. No seed phrases, no extensions, just your device.

Things I've learned and written down so I don't forget:
- Polkadot Architecture — Relay Chain, parachains, XCM, consensus, coretime
- The ETH Merge — PoW → PoS transition, what actually changed and what didn't
