Generative AI & LLMs
Natural-language interfaces and agents that understand intent and answer with each domain’s context.

Arturo
Nieve
AI Systems Engineer & Founder
I build AI systems that work in the real world —LLMs, RAG, vector search, knowledge graphs and computer vision— with a human in the loop when the decision matters.
Stack · Python · LLMs · RAG · Vector DB · Knowledge Graphs · Computer Vision · Flask · Django · Azure · Wear OS · Offline-first
Capabilities
From a question to a system that answers with sources.
The building blocks I work with, and how they fit together.
RAG
Retrieval-augmented generation: the model answers from the organization’s own documents, not from memory.
Retrieval · Chunking · Grounding
Vector search
Semantic retrieval over vector databases to find what is relevant even when the words don’t match.
Embeddings · Vector DB · k-NN
Knowledge graphs
Structured relationships between entities so answers carry context and can be traced.
Entities · Relations · Traceability
Computer vision
AI-assisted facial comparison to search for missing people, always with human verification.
Face comparison · Thresholds · Human review
Multichannel agents
Industry-specific agents on WhatsApp, Instagram, Messenger, Telegram and voice, with CRM, calendars, payments and human handoff.
WhatsApp · Voice · Handoff
Cybersecurity & forensics
15+ years in security: controls, risk management and digital forensic investigation.
Controls · Forensics · Chain of custody
Systems
Systems in production, not demos.
Each case with its problem, architecture and stack. No business figures, no named clients.
Problem
In a disaster, power and networks fail exactly when information matters most. People need to call for help, find family and locate shelter, and no AI match can be taken as true without review.
Architecture
Stack
Python · LLMs · RAG · Vectors · Geospatial · Vision · Wear OS · Offline · Azure
Problem
Businesses get more messages than they can answer. They need an agent that resolves the routine with the business’s own knowledge and hands the rest to a person.
Architecture
Stack
LLMs · RAG · Vector search · Graphs · APIs · Automation · Multichannel
Problem
The corner store keeps selling through blackouts, with no data and a line of customers. The point of sale can’t depend on the network, and an AI suggestion can’t charge on its own.
Architecture
Stack
Native Android · Offline-first · USD · Bs. · Sync · Voice
Problem
When agents do the work, it is easy to lose track of what they are doing. Mundo makes it visible: every real process shows up in a 3D headquarters, and nothing ships without human approval.
Architecture
Stack
Three.js · Python · WebSocket · AI agents · Observability
Problem
Sell, issue and validate tickets for concerts, sports, theater and corporate events without lines or fraud, with capacity control at the door.
Architecture
Stack
Ticketing · QR · Access control · Security · Analytics · Automation
Models I have trained
Machine learning with metrics, not adjectives.
Models I trained and evaluated, with their algorithm, task, validation metrics and the chart that backs them up.

- Task

- Algorithm

- Validation
- Clases disjuntas entre entrenamiento, validación y prueba; detector de fugas por píxel.

- Margen sin afinar0,091
- Margen afinado 8 épocas0,293
What I learnedOcho épocas no superan todavía al modelo preentrenado en Top-1, pero triplican el margen entre acierto y fallo, que es lo que decide cuándo puede contestar la app sin equivocarse.
There are 6 more models, trained for private projects: they are not published.
Model cards are written in Spanish.

AI principles
High-impact AI, with a human in the loop.
«At CIVIS, no facial match is accepted without human verification.»
I learned it building emergency systems, where a false positive has a first and last name. It is also where my work is heading: reliability, alignment and interpretability.
Where I’m heading
- AI reliability
- Alignment
- Interpretability
- Human-centered AI
01
Reliability
Fewer false positives over more answers. Careful thresholds, and when in doubt, ask instead of guessing.
02
Privacy
Only the data each task needs, protected and out of public view.
03
Traceability
Every answer with its source, every action with who did it and when.
04
Human in the loop
AI proposes; a person verifies and decides when the stakes are high.
