Backend engineer with 5+ years building production Node.js and TypeScript services, paired with 3+ years engineering DeFi protocols on Ethereum, Arbitrum, and Solana. I design and ship the full stack behind on-chain products: GraphQL indexers, REST and microservice APIs, Postgres data layers, AWS-native deployments, and the Solidity contracts they integrate with. Active blockchain security researcher with hands-on experience in Slither, Echidna, and Foundry fuzzing, applying the same rigor to backend systems through CI/CD, observability, and exploit-resistant design.
DeFi Lords
Lead backend development for a lending, borrowing, and yield protocol, building Node.js/TypeScript services backed by PostgreSQL and Prisma ORM, deployed on AWS. Designed and maintained GraphQL APIs for blockchain indexing across Pendle, Uniswap, and Balancer, exposing position state, vault metrics, and historical yield to web clients. Built CI/CD pipelines (GitHub Actions, Docker) for automated testing, contract deployment, and microservice rollouts, cutting release cycle time and reducing deployment errors. Architected the on-chain core in Solidity: collateral-free borrowing engine, tiered ERC-4626 yield vaults, and automated user onboarding, with security-first patterns and Foundry test coverage. Implemented real-time position tracking and protocol monitoring services, integrating CloudWatch alerts and on-chain event listeners to surface liquidation risk before it materializes.
NITDA (National IT Development Agency)
Drove Web3 adoption inside a national agency by training engineering teams on smart contract architecture, transparency tooling, and fraud-reduction use cases. Led Solidity development for pilot programs, optimizing gas usage and applying security best practices that reduced transaction costs by 30%.
Independent / Multiple Clients
Built backend services and Solidity contracts for NFT marketplaces with OpenSea/Blur-style features, including order matching APIs, indexer pipelines, and metadata services. Engineered a production NFT minting platform processing 3,338 mints at 0.025 ETH each ($330K+ transaction volume), with gas-optimized batch minting and delayed-reveal mechanics. Developed real estate tokenization infrastructure with custom paymaster contracts and automated account creation, abstracting wallet UX away from non-crypto-native investors. Implemented gasless meta-transactions across multiple client products, owning both the relayer service (Node.js + AWS Lambda) and the Solidity forwarder logic.
