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.
Automation for your business
If you run a business rather than build software, this is what I can take off your plate. Get a free automation plan for your own case, or book a call.
For clinics, dental practices and labs
Automate the busywork around patients: appointment reminders and no-show follow-ups, intake and insurance forms that fill themselves, results and referrals routed to the right place, and the reports you need pulled together on their own — so your staff spend their time on patients, not paperwork.
For accounting firms, advisors and fintechs
Take the manual work out of the numbers: invoices and statements reconciled automatically, documents chased and filed, client onboarding and KYC handled step by step, and dashboards that update themselves — accurate, on time, and ready for an audit.
For any small business, or just for yourself
One-off automations for the jobs you still do by hand: inbox and calendar triage, quotes and follow-ups, data moved between the tools you already use, and an AI assistant that answers from your own documents. We start with the one task that wastes the most time.
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

What people say
“He isn’t someone you leave to work in the background on JIRA tickets… he is someone you want to bring to your product strategy meetings. He is someone you want to put in front of your clients.”
“He knows blockchain and crypto at every level of the stack… he’s ahead of the game when it comes to agentic solutions, AI automation, and bleeding edge technology… just hire him, he’s a rock solid engineer.”
“When assigned to a Solana project with no prior Rust experience, he dove in, rapidly mastered the language, and delivered the project seamlessly and effectively.”
