Raymond Abiola — Blockchain Developer
01About

An engineer's mindset, on-chain.

I'm a Solidity developer with hands-on experience building smart contracts and full-fledged EVM-based systems using tools like Hardhat, Foundry, OpenZeppelin, and TypeScript.

Over time, I've designed and developed several blockchain projects that reflect both technical depth and real-world logic. What sets me apart is not just technical ability, but an engineer's mindset: I break problems into smart, testable units and build with maintainability and clarity in mind. I also reason deeply about protocol design, user safety, and gas efficiency.

My journey began on the non-technical side, four years in the blockchain space, including a community role on the youves DeFi protocol where I tested pre-release smart contracts on the Tezos ecosystem. That exposure to real protocol mechanics is what pulled me into engineering, and for the past two years I've focused entirely on building.

I'm now looking to bring that mindset to a serious blockchain team, one that values thoughtful engineering, curiosity, and clean architecture. Let's build something great.

Things I've shipped.

A selection of smart-contract systems and dApps; from a decentralized freelance escrow platform to peer-to-peer microinsurance. Open the case study for the full technical breakdown.

DeFi · Escrow

TrustWork

Decentralized freelancer escrow with DAO arbitration

A decentralized freelancing platform that locks client payments in escrow, releases them per milestone, and resolves disputes through a staked, randomly-selected arbitrator DAO. This is my team's capstone project at the Web3Bridge bootcamp and we were a team of five.

Governance · DeFi

FedVote

Tamper-resistant on-chain national voting

A decentralized national voting platform that prevents double-voting through cryptographic identity hashing and rewards civic participation with tokens and soul-bound NFT badges. Built leading a team of five for the Hedera hackathon.

DeFi · Insurance

SafeCircles

Peer-to-peer microinsurance for trusted groups

A peer-to-peer microinsurance protocol where small trusted groups (5–30 members) pool weekly contributions, file photo-evidenced claims, and vote on payouts via on-chain governance. Built as team lead in a one-day Monad hackathon.

DeFi · Tokenomics

JudgeToken

ERC-20 governance token with tiered staking

A four-contract governance-token ecosystem with tiered staking, pro-rata quarterly rewards, early-withdrawal penalties, and role-based treasury management. Deployed and verified on Sepolia.

Infrastructure · Security

MultiSig Wallet

Configurable multi-signature wallet + factory

A multi-signature transaction wallet with configurable quorum, role-based signer management, and a two-phase, time-locked signer-replacement mechanism. Deployable at scale via a factory.

Uniswap V2 Mainnet Forking

DEX swap integration tested against live liquidity

A swap-execution contract integrating the Uniswap V2 router with slippage protection, tested against real mainnet liquidity using Hardhat's forking at a pinned block.
