About

I build decentralized applications end-to-end from writing and testing Solidity smart contracts to shipping production backend infrastructure and connecting it all with a clean frontend. I design systems that are deterministic, state-consistent, and resilient to on-chain event ordering issues bridging blockchain data with reliable backend architecture.

I've worked on a variety of projects, from simple websites to complex web applications. Here are a few of my favorites.

NFT Marketplace

A fully decentralized NFT marketplace running on testnet that enables users to mint, list, buy, and manage NFTs. Built production-grade backend with real-time event indexer reducing API response times 30x (from 3s to <100ms). Features crash recovery, gap-fill algorithm, and deterministic event ordering using composite indexing (blockNumber + logIndex). Serves data via PostgreSQL-backed REST API with 99%+ uptime.

ContractLens

Smart contract static analysis engine analyzing verified contracts across Ethereum, Polygon, Arbitrum, and Linea. Implements weighted heuristic risk scoring (0-10 scale), automatic proxy chain resolution (UUPS vs Transparent detection), and security pattern analysis. Optional AI layer translates technical findings into structured explanations.
