AI Product Engineering

Build

Design and delivery of LLM features and AI products that real users rely on: RAG, AI agents, multi-model routing, moderation and AI-assisted workflows, built around cost, latency and quality.

At Iluy.ai, Pablo Italo designed LLM routing across OpenAI, Anthropic, Google and xAI and shipped web, SMS and WhatsApp access to 1,500 early users. At AorForms he delivered an AI-assisted voice-signature workflow tied to verification.

What it includes

Scope

AI Product Engineering: FAQ

FAQ

  1. 01

    What AI products has Pablo Italo shipped?

    Iluy, a controlled AI assistant with multi-provider LLM routing and content standards, used by 1,500 early users on web, SMS and WhatsApp; and an AI-assisted voice-signature workflow in AorForms, an e-signature SaaS with 20,000+ users.

  2. 02

    Which LLM providers and tools does he work with?

    OpenAI, Anthropic, Google and xAI models, with LangChain and the Vercel AI SDK, inside Next.js, NestJS and Django applications.

  3. 03

    Can you add AI features to an existing product?

    Yes. Most AI work starts inside an existing product: a feature is scoped around one user task, shipped behind guardrails, and measured before it grows.

  4. 04

    How are LLM cost and reliability handled?

    Through routing between providers, caching, fallbacks, moderation and evaluation on real prompts, so each request uses a model that fits its cost and latency budget.
