About
I’m a blockchain and AI engineer. I build smart contracts, Web3 applications, and the autonomous LLM agents that interact with them.
I’m currently a senior engineer at Telegraph in Denmark, writing Solidity for cross-chain bridging and state verification, plus node infrastructure for decentralised AI compute. Before that I spent 2.5 years on AI and blockchain R&D at Antematter.
Most of my work sits where AI systems meet on-chain infrastructure. An agent that has to move money, read contract state or execute a transaction is a different engineering problem from a chatbot with an API key, and that is the problem I spend most of my time on.
I scope properly before building, document interfaces as I go, and hand over code your team can maintain without me. I’m based in UTC+5, with overlap into EU and US mornings, and open to freelance smart contract and AI agent work as well as senior engineering roles.
What I build
Blockchain & smart contracts
- Solidity contracts: ERC-20, ERC-721, ERC-1155, DAOs, DEXs, staking, vesting
- Contract review and security hardening before deployment
- Cross-chain bridging, state verification and trustless bridge logic
- Full-stack dApps: wallets, contract calls, event indexing, transaction handling
- Layer 2 deployment on Polygon, Arbitrum, Base, Optimism and zkSync
AI agents & LLM systems
- Autonomous and tool-calling agents; multi-agent orchestration
- Agents that transact: on-chain execution, wallet operations, verifiable actions
- RAG pipelines: chunking, embeddings, semantic search, reranking, evaluation
- MCP servers connecting models to APIs, databases and internal tools
Backend & automation
- Go and Rust services, gRPC, P2P networking, high-throughput systems
- Profiling and benchmarking for latency, throughput and cost
- n8n workflows and API, webhook and OAuth integrations
