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 focused on ZK, privacy, AI, Cyber and blockchain infrastructure - building systems from the protocol layer up.
- 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.
-
Waldrop - Move files from any Web2 storage (S3, Dropbox, Drive) to Walrus on Sui.
-
Waldrive - Decentralized, encrypted file storage built on Sui, Walrus, and Seal.
-
SuiLearn - developer infrastructure for the Sui ecosystem. Used by devs across the network
- SUI Contract Playground - Explore, build, and interact with Move smart contracts on Sui
- gRPC Playground - explore every gRPC method interactively
- Walrus Scan - explore and inspect Walrus blobs
- Faucet - testnet tokens, 5K+ MAU
- 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.
-
Telumina - a Stellar wallet and payments application.
-
Fomly - decentralized alternative to Typeform on SUI & Walrus.

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
