Hi, I'm CornersOfTheCity

Web3 Backend Engineer | Cosmos Ecosystem | Smart Contract Integration

GitHub Cosmos Backend

About Me

I mainly work on Web3 backend infrastructure: chain integration services, transaction state tracking, event scanners, payment/wallet flows, and admin APIs for blockchain products.

My current focus is the Cosmos ecosystem, especially Cosmos SDK / CosmWasm / CW20 / Injective-based chains, plus cross-chain backend design around IBC, Peggy, Hyperlane, Wormhole, and Skip-Go.

Current Focus

Cosmos / Injective     CW20 deployment, CosmWasm interaction, protobuf tx construction
Backend Services       Go, Node.js, TypeScript, workers, REST APIs, PostgreSQL
Bridge Infrastructure  ETH <-> Injective/Peggy, relayer state, token mapping, fee controls
On-chain Data          Event scanning, confirmations, reconciliation, monitoring dashboards
Contracts              Solidity, Foundry, Hardhat, contract deployment and integration

Tech Stack

Go Node.js TypeScript PostgreSQL Cosmos SDK CosmWasm CW20 Injective IBC Solidity Foundry Hardhat
