Say hi

Senior AI Engineer · Alicante, Spain

Unai Garay.

I build agentic RAG systems and production LLM platforms — right now, one that drafts customer SMS behind guardrails, with humans in the loop and evals gating every change.

01 What I do

Retrieval that actually retrieves, guardrails with a human in the loop — and evals that gate every change.

I care about the unglamorous half: evals, guardrails, infrastructure. It’s what decides whether a demo survives contact with real users — and right now it’s most of my job, on an LLM retention platform at Inulti.

Shipping production AI since 2018 · 3 US patent filings · published research at CIARP 2018 (Springer LNCS).

Off the clock: music, bungee jumping, climbing, paddle boarding — and a lot of photography, at @ugmpictures.

  1. to now

    Inulti Now

    Senior AI Engineer

    An LLM retention platform on AWS, end to end: AI-drafted SMS replies behind safety guardrails with human-in-the-loop review, a CRM over ClickHouse, and LLM-as-judge and synthetic-call eval harnesses gating every prompt and model change. Also: real-time voice agents on LiveKit + SIP.

  2. to

    Tekever

    Senior LLM Engineer / Data Scientist

    A pipeline that turns Signal chats into Jira tickets: semantic and temporal clustering, then LLM-written structured tickets, on Airflow and GCP.

  3. to 2025

    Sorcero

    Senior AI Engineer

    Led AI R&D for an NLU platform over unstructured medical data — theme tagging, NER, summarization, recommendation and a custom neural search engine with RAG and agents. The work behind the three patents.

  4. to

    Accenture

    Data Scientist

    NLP and topic modelling over ticketing data to speed up resolution; skills-inference tagging for employee selection.

  5. to

    Smartloto

    AI Engineer

    Deep-learning image validation for lottery tickets on GCP, with on-device inference on Android and iOS.
