My name is Filipe Estácio. I'm a software engineer and cloud architect based in Caldas da Rainha, Portugal 🇵🇹, and I build AI systems that actually do real work — not flashy demos, but reliable helpers you can trust with the day-to-day.

Most people using AI today are chatting with it one message at a time. I go a step further: I build teams of AI agents that pick up tasks, do the work, and hand it back for a human to approve — with guardrails that stop them from ever going off the rails.

I run my own fleet of AI agents that work together like a small, tireless team — and I built the whole system underneath them. In plain terms, that means I know how to:

• Turn AI into a real workforce — multiple agents that plan work, write code, review each other, and tee it up for a human's yes/no. You stay in charge; they do the heavy lifting.
• Keep it safe by design — every agent runs in its own locked-down space with strict limits. The worst a misbehaving agent can do is suggest a change you still have to approve. Nothing reaches customers without a human saying go.
• Make AI trustworthy, not just impressive — automatic testing, code and security checks, and cost limits on everything, so you get the speed of AI without the nasty surprises (broken releases, runaway bills).
• Prove it works — dashboards that show what the AI did, on what, and what it cost, so you're never flying blind.

The goal I build toward: AI that handles the routine work on its own, and a human who simply reviews the results — getting the leverage of a bigger team without the overhead.

I'm taking on a small number of AI consulting projects on the side. If your team is curious about AI but not sure how to use it safely and for real work — beyond the chatbot — that's exactly what I do. I can help you:

• Find where AI will actually save you time and money (and where it won't)
• Set it up so it's reliable, safe, and cost-controlled from day one
• Get your team confident using it

• 🛠️ Software Engineer @ Aircall — building communications software used by thousands of teams.
• ⚡ CTO & Co-Founder @ My Utility Connection — a UK startup I co-founded and built from the ground up on cloud infrastructure.

Before tech, I was a civil engineer — I even helped run London's water networks during the 2012 Olympics. That mix of real-world engineering and software is how I think about AI too: powerful, but only useful when it's dependable.
