Summary

I’m a Full Stack Engineer with two years of production experience currently building in blockchain

and I’m reaching out because this company is the kind of team I want to grow with.

What attracts me to Web3 is the combination of software engineering, distributed systems,

security, and protocol-level architecture. My approach is entirely hands-on: I build projects

end-to-end, from contract design through to the frontend that users interact with. I’ve shipped a

DeFi staking dApp and a crypto banking platform both with full Web3 frontend integration using

ethers.js and MetaMask and I maintain 6 active blockchain repositories on GitHub, with NFT

contracts and additional protocols in progress.

My smart contract work is grounded in OpenZeppelin standards (ERC-20, ERC-721, Ownable,

AccessControl) and I test thoroughly with Foundry both unit tests and fuzz tests. Fuzz testing in

particular is something I apply deliberately: feeding contracts randomised inputs to surface edge

cases and unexpected behaviour before anything goes near a testnet. I understand that

deployed contracts are immutable, and that discipline in testing is what separates solid on-chain

code from vulnerable code.

My full-stack background is a genuine asset in this space. I can write the contract, build the

interface, integrate the wallet, and think about the user experience without needing separate

teams for each layer. I’ve shipped production software, debugged complex systems, and

integrated external APIs, which means I move fast and don’t need hand-holding on

fundamentals.

I’m looking for a team where I can grow as a blockchain developer while contributing across the

full stack from day one.

All my projects and repositories are on GitHub. I'd be glad to walk through any of them in a call.

Thank you for your time and consideration.

Best regards,

Sara Deleyto
