End-to-End Delivery
DeFi protocols secured by testing and informed by finance.
Core Skill Set
Blockchain depth with product delivery range.
My strongest work sits where protocol design, financial risk logic, and usable Web3 interfaces meet. I can reason about contract behavior, test assumptions, and still build the frontend flows users need to interact with the protocol.
DeFi Protocols
CDPs, over-collateralized stablecoins, AMMs, Uniswap v3, staking, lending pools, health factors, and liquidations.
Testing & Security
Foundry unit tests, integration tests, fuzzing, invariant checks, oracle-risk awareness, and edge-case coverage.
Web3 Tooling
Foundry, Hardhat, Ethers.js, Web3.js, WalletConnect, MetaMask, Alchemy RPC, Chainlink, CCIP, IPFS, and Pinata.
Frontend / Backend
TypeScript, JavaScript, Next.js, React, Node.js, Express.js, MongoDB, dashboards, wallet flows, and contract interactions.
Finance-Aware Engineering
MSc Finance background supporting better judgment around collateral, liquidation paths, solvency, and DeFi risk controls.
Core DeFi Project
DeFi systems built around risk, liquidity, and secure smart contracts.
These projects focus on the parts of DeFi that matter in production: collateral movement, pricing assumptions, liquidation paths, vault accounting, tokenized claims, liquidity design, and tests that challenge the protocol before users do.
Nexus StableCoin Protocol
An over-collateralized decentralized stablecoin system engineered around explicit solvency constraints, oracle-aware collateral valuation, liquidation logic, and adversarial tests.
Stablecoin systems fail when price assumptions, collateral accounting, or liquidation paths break under adverse conditions. The design must remain understandable under stress, not only during normal operation.
Aegis Bank
A non-custodial lending market exploring isolated risk pools, utilization-based interest rates, health factors, oracle validation, liquidation incentives, and bad-debt containment.
Tokenized Private Credit
A permission-aware credit protocol for originating loans, tokenizing lender claims, accruing interest, processing repayments, and representing default or recovery states on-chain.
Orbis AMM Lab
A concentrated-liquidity AMM study paired with a risk simulator, exploring price curves, LP fee economics, slippage, impermanent loss, and adverse market conditions.
Liquid Staking Vault
A liquid-staking architecture focused on exchange-rate accounting, validator allocation, reward accrual, withdrawal queues, slashing exposure, and liquidity under stressed redemption demand.
Broader Blockchain Delivery
Other shipped Web3 products beyond DeFi.
These projects are not pure DeFi protocol work, but they show production delivery across token launches, marketplaces, NFT flows, wallet UX, metadata storage, and event-driven dApps.
Crypto ICO Marketplace & ERC-20 Token Launchpad
Full-stack Web3 launchpad for creating ERC-20 tokens, launching ICOs, managing token sales, and running the complete on-chain workflow on Polygon Amoy.
Integrated MetaMask and Ethers.js for wallet transactions and network validation, secured token-logo uploads through a server-side Pinata API, and tested the core workflows before deployment on Vercel.
Unlock Estate — Web3 Real-Estate Marketplace
Full-stack decentralized real-estate marketplace built with Next.js, Solidity, Hardhat, MetaMask, Pinata/IPFS, and Ethers.js, with smart contracts deployed on the Polygon Amoy testnet.
The platform supports property listing, purchasing, ownership transfer, price updates, listing fees, and on-chain reviews. I connected the contract layer to a responsive Next.js frontend and integrated Pinata/IPFS so property media and metadata can be handled through decentralized storage.
Artefact — NFT Marketplace
Full-stack ERC-721 marketplace for minting, listing, discovering, and purchasing digital collectibles.
I built and tested the smart-contract purchase flow with separate seller and buyer wallets, connected MetaMask through Ethers.js, and deployed the responsive marketplace interface on Vercel.
Supply Chain & Logistics Tracking Protocol
Ethereum-based shipment state tracking with role-based access control and event-driven frontend synchronization.
I restricted shipment updates to approved dispatch roles and built Ethers.js providers for MetaMask synchronization, contract event listening, and reliable frontend shipment updates.
Security & Testing
Built around the failure modes that matter in DeFi.
I approach blockchain development as adversarial engineering. Contracts need to work under pressure: unexpected user actions, unsafe prices, liquidation edge cases, access-control mistakes, and broken accounting assumptions.
Invariant Testing
Protocol properties checked across stateful user actions.
Fuzz Testing
Edge cases explored beyond the normal happy path.
Access Control
Clear permissions for sensitive state changes and administrative paths.
Oracle Risk
Price feed assumptions considered in collateral and liquidation logic.
Advanced Research Areas
Where I’m pushing deeper.
Tokenized Ownership
RWA ownership claims, property transfer logic, ERC-based asset representation, permission boundaries, and finance-aware settlement flows.
Cross-Chain Interoperability
Chainlink CCIP concepts, cross-chain message passing, token transfer design, and multi-chain synchronization risks.
Account Abstraction
ERC-4337 smart accounts, UserOperations, paymaster concepts, gasless execution, and alternative signature validation patterns.
Finance × DeFi Expertise
Where finance and investment meet DeFi protocol engineering.
MSc Finance and InvestmentUniversity of Wales, Wales, UK | 2013
Finance-informed DeFi judgment Applying finance and investment judgment to collateral design, cash-flow logic, incentives, liquidity, solvency, leverage, and risk transfer in smart contracts.
Solvency
Keep liabilities covered under realistic collateral, oracle, and price-stress assumptions.
Liquidity
Separate recorded protocol value from available exits, withdrawals, and liquidation capacity.
Incentives
Model how borrowers, lenders, and liquidators behave when pressure or profit appears.
Risk controls
Encode limits, permissions, circuit breakers, and failure containment directly into protocol logic.
Open Channel
Building financial infrastructure on-chain?
I’m open to DeFi protocol, Solidity, smart-contract testing, RWA tokenization, and full-stack Web3 opportunities with teams that value explicit risk reasoning.
