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.
AI Engineer · LLM agents and automation in production since 2025 · 30 years in IT
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?
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.
Every solution comes from a real problem. Recognise any of them?
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 SolutionClients 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 SolutionEnquiries that ask for information and disappear. Time spent on people who were never going to buy. I solve it with automatic qualification.
See SolutionAnswering emails eats up hours that should go into the business. I solve it with automatic triage, replies and scheduled follow-ups.
See SolutionInformation 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 SolutionDocuments to review, reports to prepare, routine decisions. I solve it with assistants that do that work for you.
See SolutionDifferent problems, tailor-made solutions. Choose your sector.
Patients who call after hours and cannot book an appointment.

The Problem: Patients calling after hours to book, no answer, no appointment. Implementation of automated WhatsApp service with booking and reminders.
The Problem: Portal leads arriving without a timely reply: the client had already gone elsewhere. Automatic qualification system integrated with property management.
The Problem: The receptionist on the phone instead of serving clients in person. Gaps and no-shows in the schedule. Automated booking with confirmations and waiting-list management.
Problem: Legal research, contract review and email triage consuming days of the lawyer's work.
Solution: A research and drafting assistant tailored to the firm, aggregating legal codes, analysing contracts and drafting from structured templates. The lawyer always has the final word.
Typical task: 30 min AI-assisted and 30 min of review. In production since November 2025.
Problem: Technical and documentary answers depending on whoever knows where the information is.
