AI and blockchain backends in Python, Go, and Rust

I build AI systems that make it to production — not demos that break under real traffic. My work is AI agents, LLM integrations, and the backend underneath: pipelines, APIs, and services in Python, G...

About this Gig

If your backend can't keep up timeouts under load, an indexer falling behind the chain, an AI service costing more than it should that's the work I do.


I build production backends in Rust, Go, and Python for AI and blockchain systems. Not prototypes. Systems that stay up under real traffic.


Recent work: rewrote an overloaded Node.js service in Go with a Rust module for the compute-heavy path. p99 latency went from over 1s to under 100ms, on less infrastructure.


What I build

  • Backends in Rust (speed, memory safety) or Go (concurrency)
  • Python services with AI/ML HuggingFace, PyTorch, LangChain, agents
  • Blockchain integration on Ethereum, Base, Solana, other EVM chains
  • Smart contract indexers, oracles, on-chain data pipelines
  • REST/GraphQL APIs, databases, AWS/GCP deployment with Docker


How I work

I'll tell you upfront if your architecture is wrong or the job doesn't need the stack you're asking for. You get documented, tested code another engineer can maintain. Previously a senior backend engineer at pCloud.


Not a fit if you want a token launched fast with no testing.

Message me what you're building and I'll tell you honestly if I'm the right person.

    Bojan's work was nothing short of OUTSTANDING—attentive to details, highly professional, and went beyond what was expected. Working with him was an absolute breeze thanks to his politeness, seamless communication, and excellent collaboration skills. Highly recommend! 🙌
