AI and blockchain backends in Python, Go, and Rust

About this Gig

Most web3 games fail on the technical side contracts that leak value, on-chain calls that make gameplay feel broken, AI agents that are really just scripted dialogue.


I build the backend and on-chain layer for web3 games: smart contracts for in-game assets, the infrastructure connecting your game client to the chain, and AI agents with real behavior rather than fixed responses.


What I build

  • NFT and token contracts for in-game assets tested, gas-optimized, audit-ready
  • AI agents and NPCs with memory and adaptive behavior (Python, LangChain)
  • Game backends in Rust or Go that handle real concurrent players
  • Chain integration on Ethereum, Base, and Solana
  • Wallet connection and transaction flows that don't interrupt gameplay


How I work


I build the backend, contracts, and AI. If you need a Unity or Unreal client, I'll integrate with your game developer rather than pretending to be one.


I'll tell you upfront when something belongs off-chain. Most games put too much on-chain and pay for it in cost and latency.


Message me with what you're building and I'll tell you honestly whether I'm the right fit.

    I would definitely recommend him to anyone looking for a reliable and skilled Solana developer. Overall, I would rate my experience as 5 out of 5 stars. The quality of the work was remarkable. Bojan's expertise in Solana and blockchain technology was evident, and their innovative approach to solving complex problems impressed me.
