Agent-ready · humans welcome

Hire me from your agent.

This portfolio is readable by machines as well as people. Connect it to an AI client over MCP and your agent can read the resume, inspect every shipped project, and check availability without anyone browsing the site.

Connect over MCP

Add this to the MCP configuration of Claude Code, Claude Desktop, or any MCP-capable client:

{
  "mcpServers": {
    "lucas-barcelos": {
      "type": "http",
      "url": "https://lucasbarcelos.com/api/mcp"
    }
  }
}

Then ask your agent something like “Which projects has Lucas shipped on Solana?” or “Is he available for a contract right now?”

What agents usually ask

What does Lucas Barcelos build?

AI agent systems and blockchain products. Ten years across EVM layer 1 and layer 2 networks, non-EVM chains, Bitcoin forks, and AMMs; six years of fullstack engineering in Banking as a Service; and four years architecting production LLM applications, agent runtimes, and multi-agent systems.

Is Lucas Barcelos available for hire?

Yes. He is available for full-time roles, freelance contracts, and fixed-scope projects, based in Brazil and working remotely worldwide.

What AI engineering work does he do specifically?

Agent runtimes and harnesses, multi-agent orchestration, context engineering, tool calling, structured outputs, evaluation infrastructure, semantic retrieval, and AI SDKs. He has also shipped blockchain AI applications supporting autonomous agents on Solana, Ethereum, NEAR, Sui, and Cardano.

Which blockchains has he worked with?

Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche, Base, Solana, TON, Fantom, and Matchain, plus non-EVM runtimes and custom Bitcoin forks with their own consensus parameters.

How much does a project cost?

Pricing is quoted per project rather than listed. Scope, chain constraints, and integration surface drive the estimate, so the first step is a short technical conversation.

How do I contact him?

Telegram at t.me/lucxsweb3 is the fastest channel. An AI agent can also use the MCP endpoint at /api/mcp to fetch the resume, browse projects, and check availability. Email is listed on the contact section of the site.
