30 Years of Experience in Technology

André Carmo

The work that holds your business back.

I don't sell software. I listen to the problem, design the solution and implement it in days. Customer service, scheduling, client management: your business running without depending on you for everything.

About Me

A consultant who solves. Then implements.

30 years solving operational problems in Portuguese companies. My work starts with a simple question: what is costing your business the most time and money?

AI Technology

Why Work With Me?

I am an AI engineer specialised in automation. Since 2025 I design, build and run LLM agents and workflow automations in production for SMEs and professional practices: WhatsApp agents that answer, qualify and book 24/7, research and drafting assistants over company documents, and integrations between CRM, ERP, calendar, email and messaging. Behind it are 30 years in IT, including 5 years in software engineering teams at Altran and Capgemini Engineering and a decade running infrastructure. That is what makes the systems production-grade: scenario-based tests, guardrails and human fallbacks on every deployment. My work starts with a simple question: what is costing your business the most time or customers.

  • Free diagnosis of what is holding the business back
  • Tailor-made solutions, not off-the-shelf products
  • Implementation in 24-48h, with no impact on operations
  • Training included and ongoing support
  • No long contracts: results before payment
What I Solve

Does your business have one of these problems?

Every solution comes from a real problem. Recognise any of them?

Missed calls after hours

A customer calls after 6pm and nobody answers. By the next day they have chosen someone else. I solve this with automated 24/7 customer service.

See Solution

Gaps and no-shows in the schedule

Clients who do not show up, wasted hours, a receptionist stuck on the phone instead of serving people. I solve it with automated booking and reminders.

See Solution

Leads that arrive and never convert

Enquiries that ask for information and disappear. Time spent on people who were never going to buy. I solve it with automatic qualification.

See Solution

An inbox that never empties

Answering emails eats up hours that should go into the business. I solve it with automatic triage, replies and scheduled follow-ups.

See Solution

Data in different places, never connected

Information in Excel, more in the CRM, more in the invoice. Someone does the copy-pasting. I solve it by connecting your systems to each other.

See Solution

Repetitive tasks that steal hours

Documents to review, reports to prepare, routine decisions. I solve it with assistants that do that work for you.

How I Build

From Idea to System in Production

The technical layer behind every solution.

LLM Agents

Claude API and Claude Agent SDK, OpenAI API, tool calling and structured outputs, MCP. Conversational logic in code (Python and TypeScript) where visual flows hit their limit.

Orchestration and Integration

Self-hosted n8n, REST APIs, webhooks, WhatsApp Business API, Google Workspace and Microsoft 365, clients' CRM and ERP.

Documents and Knowledge

RAG with embeddings and hybrid search on Supabase/pgvector, answers with sources and handover to a human when confidence is low.

Quality

Scenario-based regression suite (pytest) on every prompt or model change, validation against the real calendar before the user sees the answer, defined fallback paths.

Operations

Docker on a VPS, managed platforms or the client's own server, structured logging with token and cost control per conversation.

Delivery

Discovery with the business owner, impact-based prioritisation, first release usually within 48 hours, documentation and handover.

Portfolio

Completed Projects
