I'm Tiago Peres, an AI Engineer & Full-Stack Developer in Portugal. I help teams and founders put AI into production: RAG systems, AI agents, LLM features and MVPs. I've shipped production AI at Nestlé and PwC, and I've spent 10+ years building software for enterprises and startups.
Some teams know what they want built. Some have AI in the plan and no idea where it fits. Some have a build that stalled. Whichever it is, you work directly with the engineer who scopes and builds it.
Live in production, not demos
- Nestlé: GenAI scientific-intelligence platform with hybrid retrieval over terabytes of internal data.
- PwC: AI-enabled internal-audit platform built for accuracy and traceability over sensitive documents.
- Legal AI: legal-research SaaS with citation-backed answers across 500k+ rulings and statutes, four jurisdictions, Arabic and English.
- Health AI: citation-backed medical search over peer-reviewed literature.
What you can hire me for
- MVP in 4 to 8 weeks for non-technical founders: a product real users can sign up to and pay for, with the code yours from the first commit.
- AI applications, integrations and chatbots over your own content and systems, with evals and monitoring.
- Practical AI for your business: find where AI pays and automate the workflows that hurt most.
- Digital transformation without the hype: start at the bottleneck and measure whether it moved.
How it runs: a reply within one business day, a free 30-minute call (no pitch), a fixed price in writing (or a weekly rate for ongoing work), then a working demo every week, not a status report.
Fully remote on EU and US hours. NDA-friendly.
Stack: Python, FastAPI, React, Next.js, PostgreSQL, LangChain, LangGraph, OpenAI, Kubernetes/OpenShift, Azure, GCP.

Our Story
I'm Tiago Peres, an AI engineer and full-stack developer in Peniche, Portugal. Tiago Martins Peres, Unipessoal Lda is my company, founded in 2021, and you work with me directly: I scope, build, deploy and hand over every project myself. I care about AI that holds up in production, not demos that impress once. That means a fixed price in writing before anything starts, a working demo every week, everything built yours to keep, and a straight answer when AI is not the right fix.
Meet the Team
Tiago PeresFounder, AI Engineer and Full-Stack Developer

What Sets Us Apart
You work with the engineer who builds it
The person on your first call is the one who scopes, builds, deploys and hands over the work. I read every message myself and reply within one business day.A fixed price, in writing
Scope and price are agreed in writing before anything starts, and any change is re-quoted in writing before it is built. You know the number before you commit.A working demo every week
You see working software every week, not a status report, so a wrong turn shows up in week two, not week eight.
