Operating principles

Built on solid engineering logic.

</>

No-hype solutions

If a simple script works better than a neural network, I build the script. Function over trends.

Speed to execution

From concept to working implementation in weeks, not quarters.

🛡

Reliable security

Your data integrity and system vulnerabilities are assessed with uncompromising rigor.

🌐

Global, bilingual

Location-agnostic delivery for clients worldwide, in English and Spanish.

Core capabilities

Fixed-quote AI engineering.

Stop paying for open-ended consulting that leads nowhere. I define the scope, set a fixed quote upfront, and deliver a specific technical outcome.

Assistants / RAG

AI assistants trained on your documents

A chatbot that answers accurately from your own documentation — support, internal knowledge, or client-facing. No invented answers.

Agents & automation

Custom AI agents & automation

Automate the bottleneck: reports, data cleanup, email workflows, multi-step processes. AI that finishes the job, not just chats about it.

Security & rescue

AI audits, security & rescue

Already launched an AI feature that's slow, expensive, insecure or wrong? I audit it, test it against prompt injection, and fix it.

About

One engineer, end to end.

I'm Jesús Devesa. I work alone, which means the person who quotes your project is the person who builds it — no account managers, no handoffs, no agency overhead in the price.
