I studied Biochemistry. Now I build DeFi protocols. š§¬āļø My path into blockchain wasn't traditional, but the engineering mindset is the same: understand the system deeply, find the failure points, and build something bulletproof. After 2+ years working on smart contract security and DeFi development, I'm now actively seeking a junior smart contract/Blockchain developer role. What I've worked on: ā Security research on protocols with $50M+ TVL (zero incidents) ā Cross-chain rebase token protocol using Chainlink CCIP ā Overcollateralized stablecoin with automated liquidation mechanics ā NFT marketplace with real-time event indexing ā ZENDER ā batch ERC-20 airdrop dApp across Ethereum, Base & Arbitrum I write secure, gas-optimized, auditable Solidity ā and I test everything before it ships. If you're building in Web3 and need a junior dev who treats code like critical infrastructure, I'd love to connect. š© [email protected] | github.com/0xAbiara #Solidity

Challenge 2 of Damn Vulnerable DeFi: Naive Receiver. Done. 1010 WETH. 2 transactions. That was the puzzle. My first thought - trigger 10 flash loans to drain the receiver. Then I counted. That's 10 transactions; I only had 2. Two bugs to chain: - The receiver had zero access control. Anyone could trigger loans on its behalf, it just paid every time - Pool read the last 20 bytes of calldata to identify callers. Append any address, impersonate anyone Packed everything into one multicall. 10 flash loans + a withdrawal disguised as the fee receiver. 1010 WETH to recovery. The 2 transaction limit wasn't the vulnerability. It was the constraint that forced me to actually think. [PASS] ā

Just did DVDF challenge 1 broke a flash loan vault with 1 token transfer `token.transfer(address(vault), 1);` The vault's assumed balance only changes via deposits. send tokens directly ā share/asset invariant breaks ā every flashloan reverts forever 1 line. vault bricked. gm š«”
