Projects
Selected work across ERC-4626 yield infrastructure, EIP-712 signed-order settlement, live marketplace delivery, verified token-sale systems, DeFi integrations, on-chain operations, backend services, blockchain tooling, and programmable payments.
Selected work
Adaptive Yield leads with ERC-4626 vault design, Aave V3 and Morpho integrations, constrained rebalancing, Base fork tests, fuzzing, and stateful invariants. OrderForge demonstrates signed-intent design, replay protection, and exact partial-fill accounting. CookingPro anchors the portfolio in sustained ownership of a live two-sided product.
DeFi protocol engineering where ERC-4626 accounting, external-strategy trust boundaries, liquidity, risk constraints, and adversarial testing have to agree before any capital is considered.
A risk-aware ERC-4626 USDC yield-optimization protocol on Base with Aave V3 and Morpho adapters, constrained rebalancing, fork testing, fuzzing, and stateful invariants.
Signed-order protocol engineering where cryptographic intent, lifecycle state, settlement math, and adversarial testing all have to agree.
A non-custodial EIP-712 signed limit-order settlement protocol with partial fills, ERC-1271 smart-wallet signatures, replay protection, and stateful Foundry invariants.
Production restaurant operations and customer ordering across three mobile applications.
A production restaurant-management and customer-ordering platform spanning an Android management application plus Android and iOS customer experiences. I contributed across product functionality, mobile workflows, supporting APIs, quality, and releases.
Hackathon builds
CSPR AgentPay Guard and CupTreasury remain together as clearly scoped, reviewer-facing hackathon builds.
A policy-controlled payment firewall for autonomous agents using HTTP 402 and Casper Testnet proof recording.
A policy layer binds payments to exact requests, applies allowlists and spending limits, rejects replay attempts, and exposes a Casper verification path without giving the hosted app access to private keys.
My contribution: Designed and built the policy engine, HTTP 402 flow, Casper integration path, audit trail, tests, and reviewer-facing dashboard.
A self-custodial football team treasury with deterministic approvals and WDK-guarded payment intents.
The prototype models squad contributions and match-day expenses, then turns role-based approvals into exact payment capabilities with policy simulation and safe no-broadcast signing.
My contribution: Designed and built the treasury product, Captain/Treasurer approval model, guarded payment-intent flow, WDK proof surface, and automated verification.
More case studies
Verifiable token-sale infrastructure with escrowed payments, phase-aware pricing, refund protection, vesting, and a fully documented Sepolia release.
A verified Ethereum token-sale reference on Sepolia with escrowed payments, oracle pricing, exact-asset refunds, vesting, and Foundry invariant testing.
A complete V2 liquidity-management integration covering token approvals, swaps, LP custody, one-sided entry, single-token exit, dust refunds, live on-chain state, transaction simulation, and realistic fork testing.
A non-custodial Solidity and Next.js application for exact-input token swaps and one-click Uniswap V2-compatible liquidity management on Arbitrum, including one-sided pool entry, standard LP removal, and single-token exit.
Aviation turnaround operations modeled as on-chain workflows.
A blockchain-based aviation turnaround management dApp where each flight turnaround is represented by a smart contract that tracks ground tasks, deadlines, KPIs, and on-chain certification.
A complete DeFi swap integration built around explicit execution guarantees, temporary allowances, and reproducible protocol testing.
A security-aware Uniswap V2 integration covering ERC-20 approvals, router quotes, exact-input swaps, bounded slippage, deadlines, temporary allowances, and reproducible Arbitrum fork testing.
A Web2/Web3 vacation-rental platform focused on trust, search, and smoother guest/host interactions.
A vacation-rental platform combining Web2 product functionality with Web3-oriented features, focused on trusted listings, user verification, search experience, and smoother guest/host interactions.
Unified blockchain, market, and developer data for the Casper ecosystem.
A Web3 platform for the Casper ecosystem combining blockchain data, GitHub project data, and cryptocurrency market data into a unified backend and frontend experience.
A Ganache-like local testing environment for Casper smart contract workflows.
A blockchain application suite and Ganache-like testing environment for the Casper blockchain, packaging CCTL functionality in a Docker-based UI to improve local development and testing workflows.
15+ DeFi and smart contract systems covering swaps, liquidity pools, yield farming, lending, token mechanics, and security patterns.
A hands-on portfolio of 15+ blockchain projects covering DeFi protocols, token systems, smart contract security, and production-oriented Solidity patterns.
Internal translation API with provider abstraction, caching, PostgreSQL statistics, and CI/CD.
An internal translation API built for A3M to provide multilingual translation services through multiple third-party providers with caching and statistics.
End-to-end MERN application for user registration and interactive kata creation.
A MERN-stack web application that allowed users to register, create katas, and interact with them.
