Hi, I'm Junghoon Ban 👋

Backend & Blockchain Engineer building DeFi infrastructure across off-chain systems and on-chain smart contracts.

Currently working on GnoSwap, a concentrated liquidity AMM DEX for the Gno.land ecosystem.

I like building systems that connect:

  • reliable backend infrastructure
  • blockchain execution layers
  • smart contracts
  • product-facing applications

What I work on

  • DeFi applications and DEX development
  • Smart contracts on Gno.land
  • Backend systems for blockchain products
  • Event-driven systems, data pipelines, and APIs
  • Developer tools and infrastructure

Tech Stack

Backend

  • Golang
  • Kotlin, Java, Spring Boot
  • Kafka, Redis, MongoDB, PostgreSQL, MySQL

Blockchain

  • Gno.land / Gnolang
  • Cosmos / IBC
  • DeFi, AMMs, staking, token mechanics

Frontend

  • TypeScript, Next.js

Philosophy

I don't believe one technology solves every problem.

I care about choosing the right tool for the right layer — from backend systems to smart contracts, from infrastructure to user-facing products.
