You will get I will build a custom AI agent that uses tools and automates your tasks
Project details
I build AI agents that don't just chat — they get work done. Using tool
use / function calling, the agent looks up live data, calls your APIs,
takes actions and completes multi-step tasks on its own, while you stay
in control of what it's allowed to do.
I've built a production AI agent that runs on WhatsApp for a real
operations team: 8 custom tools that query databases, pull live metrics,
log events and run engineering analysis on demand — with guardrails that
keep it from inventing answers or taking unwanted actions. It replaced
slow manual lookups and data entry with instant, reliable automation.
Whether you need an internal ops agent, a customer-facing assistant that
can actually do things, or an autonomous workflow that runs on a
schedule, I deliver a dependable, well-documented agent — not a demo.
Tell me the task, and I'll build an agent that handles it.

About Juan David
AI Automation Engineer | RAG Chatbots & n8n Workflows
Cali, Colombia - 7:04 pm local time
I specialize in three things, end to end:
• AI agents & chatbots — conversational assistants (WhatsApp, web) powered by Claude/GPT, with tools that query your real data and act on it.
• RAG systems — turn your documents and knowledge base into accurate, searchable answers (embeddings + vector search), with guardrails against hallucination.
• Workflow automation — n8n / Make pipelines that connect your stack (Sheets, Excel, Notion, Gmail, APIs) and remove manual work.
Recent production work (energy-sector operations):
• A WhatsApp AI assistant with RAG over 150+ technical documents + 8 custom tools — operational lookups went from minutes to seconds.
• A vision pipeline that turns photographed forms into structured Sheets/Excel data — eliminated manual data entry.
• A daily AI briefing + email triage system — cut review time and reduced LLM cost ~20x by batching.
I care about systems that actually ship and keep running in production — not demos.
Stack: Claude API · OpenAI · n8n · Make · Supabase (pgvector) · Python · Notion/Google/Microsoft APIs.
Tell me the manual process that's eating your team's time, and I'll tell you how to automate it.
Steps for completing your project
After purchasing the project, send requirements so Juan David can start the project.
Delivery time starts when Juan David receives requirements from you.
Juan David works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & task mapping
I review the task, the tools involved and the decisions the agent must make, then share a short plan of how it will work and what stays under human approval.
Tool & integration setup
I connect the agent to your systems and APIs (CRM, database, calendar, email, internal tools) and define each tool it can call.
