Freelance AI agent development

Autonomous agents that turn manual operations into self-directed workflows, with reasoning, tool calling and guardrails built in.

What you get

An AI agent plans a task, calls your tools to do it and checks its own work. These are the parts I build.

Multi-agent planning and execution
A planner and specialist agents split a task into steps, run them and hand back one result.
Custom tool calling
Agents that act through your tools: Slack, your CRM, SQL databases and internal APIs.
Human-in-the-loop review
Review checkpoints before an agent sends, spends or changes anything that matters.
Token budgets and observability
Hard limits on token spend per run, and logs that show what each agent did.
2–3wtypical build for an autonomous agent or swarm. A focused first version can fit a 10–14 day sprint.

How it works

Four moves, from brief to production
  1. i.

    Scope

    Share the workflow you want automated. You get a scope and timeline estimate, with a direct reply within 12 hours.

  2. ii.

    Architect

    Agents, tools and fallbacks are planned before the first line of code is written.

  3. iii.

    Ship

    The agent goes live with its tools connected and its review steps switched on.

  4. iv.

    Harden

    Guardrails, token budgets, observability and model fallbacks keep it running when a provider does not.

Questions people ask

What is an AI agent?
An AI agent is software that uses a language model to decide what to do next, calls tools such as APIs, databases or messaging apps to do it, and repeats until the task is finished. A chatbot only answers; an agent also acts.
How long does it take to build an AI agent?
Typically 2–3 weeks for an autonomous agent or swarm. A focused first version can fit a 10–14 day sprint. The number of tools and integrations is the biggest factor. Read what changes the timeline.
Can the agent work with our existing tools?
Yes. Agents act through tool calls, so Slack, a CRM, SQL databases and internal APIs can be connected. Risky actions can wait for a human to approve them.
How do you stop an agent from going wrong or overspending?
Human-in-the-loop review before sensitive actions, token budget limits on every run, and logging so each step can be inspected afterwards.
