Smart Contracts
Solidity, EVM, ERC-20, ERC-721, ERC-4337, access control, modular state design, and gas-aware implementation.
Blockchain Engineer · Web3 Protocol Builder
I build Web3 and EVM protocols that move DeFi value.
Blockchain Software Engineer focused on EVM-compatible protocols, secure smart contracts, cross-chain liquidity, and production-grade DeFi architecture.

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.
Project Experience
Protocol work presented as employer-ready case studies.
Each project shows a different part of the blockchain stack: contract architecture, DeFi mechanics, wallet integration, backend support, analytics, and security testing.
Nexus StableCoin Protocol
Built an over-collateralized stablecoin protocol for depositing WETH and WBTC, minting NexusUSD, repaying debt, redeeming collateral, and liquidating unhealthy positions.
Integrated Chainlink-style price feeds, health-factor risk controls, DAO governance, MetaMask, a responsive Next.js dashboard, and Foundry unit, fuzz, invariant, and integration tests.
Algorithmic Decentralized Stablecoin ($DSC)
Over-collateralized stablecoin system with Chainlink pricing, liquidation routines, and protocol health checks.
I integrated Chainlink Price Feeds for tamper-resistant asset valuation and built Foundry invariant and stateful fuzz tests to challenge the protocol's solvency assumptions.
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.
I integrated MetaMask and Ethers.js for wallet connection, token purchases, transfers, withdrawals, inventory tracking, and network validation. I also implemented secure token-logo uploads to IPFS through a server-side Pinata API, added automated tests for core workflows, and deployed the tested application on Vercel with a custom domain.
Blockchain Real-Estate Marketplace dApp
Peer-to-peer property marketplace with Solidity transaction flows, decentralized media storage, and wallet onboarding.
I connected Polygon smart contracts to a dynamic Next.js frontend and integrated Pinata IPFS gateways so property media and metadata could be stored through decentralized infrastructure.
NFT Marketplace Protocol
NFT marketplace combining Solidity contracts, a React / Next.js client, and a Node.js / Express backend.
I built backend error handling and MongoDB schemas for marketplace state, then abstracted contract interactions into reusable React hooks to keep wallet and transaction flows cleaner.
Supply Chain & Logistics Tracking Protocol
Polygon Amoy shipment lifecycle tracking with escrowed test POL and event-driven frontend synchronization.
I deployed a shared Solidity contract for shipment creation, dispatch, delivery, and escrow settlement, then connected it to distinct V1 and V2 Next.js interfaces with MetaMask network enforcement and Amoy-compatible transaction handling.
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.
DeFi Lending Architecture
CDPs, liquidation engines, health factor design, stablecoin solvency, AMM integration, and MEV-aware liquidation considerations.
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.
