Full stack and blockchain developer with a focus on developer tooling, DeFi protocol engineering, and smart contract security. I build end-to-end — TypeScript CLI tools, Python SDKs, React frontends, Solidity/Clarity/Rust smart contracts, and backend indexers — and I ship independently without a team.

Grant recipient from the Arbitrum Foundation and the Stacks Foundation. Active security researcher with 20+ confirmed High/Medium findings across Sherlock, Code4rena, Cantina, and Immunefi. Polkadot Technical Fellowship candidate and Polkadot Blockchain Academy graduate, with open-source contributions to paritytech/polkadot-sdk. I audit the same protocols I know how to build, which means I find what others miss.

CLI development environment for Arbitrum Stylus (Rust) smart contracts. Think Hardhat, but for Stylus.

Arbitrum grant-approved. Shipped both milestones.

MCP framework that lets AI agents autonomously manage DeFi positions on Rootstock/Bitcoin — with policy enforcement and session-scoped spend limits.

        ├── get_protocol_data  → Money on Chain + Tropykus RPC
        ├── simulate_swap      → viem call/estimateGas (no broadcast)
        ├── execute_intent     → Session validation → Policy engine → sendRawTransaction
        ├── get_position_health → Tropykus health factor
        └── get_wallet_balances → RBTC + ERC-20 balances

5 hard-coded policy rules block every unsafe action before broadcast — zero-address transfers, selfdestruct calls, single-tx values over 10 RBTC, spend cap overflows, and non-whitelisted contracts. Every decision (allow or deny) is written to an audit log.

Protocol integrations: Money on Chain (MoCState — BTC price, coverage ratio, BPRO/DOC rates) · Tropykus (Compound fork — supply/borrow APY, per-account health factor)

Python SDK for the Rootstock (RSK) blockchain — wallet management, ERC-20 tokens, smart contracts, RNS domain resolution.

from rootstock import RootstockProvider, Wallet, ERC20Token

provider = RootstockProvider.from_mainnet()
wallet   = Wallet.from_private_key("0x...", chain_id=30)

# ERC-20 in 3 lines
rif = ERC20Token.from_symbol(provider, "RIF")
print(rif.balance_of_human(wallet.address))   # "150.5"
receipt = rif.transfer(wallet, to="0x...", amount=100 * 10**18)

# EIP-1191 Rootstock-specific checksum
addr = to_checksum_address("0x5aaeb6...", chain_id=30)

Covers: Wallet create/import/encrypt · RBTC transfers · ERC-20 (balance, transfer, approve) · arbitrary contract call/transact · RNS forward + reverse resolution · gas estimation · mainnet and testnet

Non-custodial sBTC yield optimizer on Stacks — compare live APY across Bitflow, ALEX, Zest, Velar, and Hermetica; rebalance in one atomic Clarity call.

;; vault.clar — core deposit/withdraw, 5% performance fee on yield only
(define-public (deposit (amount uint)))
(define-public (withdraw (amount uint)))
(define-read-only (get-position (user principal)))
(define-read-only (get-accrued-yield (user principal)))

;; yield-source trait — every protocol adapter implements this
(define-trait yield-source-trait
  ((get-current-apy  ()    (response uint uint))
   (deposit-sbtc     (uint) (response bool uint))
   (withdraw-sbtc    (uint) (response bool uint))))

Adding a new protocol = one new adapter contract. Core vault never changes.

Beyond my own repos, I contribute directly to protocol-level infrastructure used by other teams:

• Bitcoin Dev Kit (BDK) — Added a fuzz/ crate with three cargo-fuzz targets: apply_update (fuzzing Wallet::apply_update with arbitrary txs/anchors), create_tx (fuzzing build_tx with arbitrary fee rates, amounts, and RBF), and descriptor_parse (fuzzing arbitrary bytes through IntoWalletDescriptor, covering miniscript/key-path/checksum handling) — plus a fuzz.yml CI workflow that builds on every PR and runs extended 60-second fuzzing sessions weekly with crash-artifact upload. (issue #61)
• Polkadot SDK — Open and merged pull requests on pallet-revive's Ethereum JSON-RPC layer, part of ongoing Polkadot Technical Fellowship work. (view my PRs →)

20+ confirmed High/Medium findings across Sherlock, Code4rena, Cantina, and Immunefi. The same protocol knowledge that lets me build DeFi tooling also lets me find what breaks it.
