AI Integration & Development
When off-the-shelf tools do not fit, we build the system around how your business actually runs.
What it is
Here's the short version.
AI Integration & Development is PerezCarreno & Coindreau's engineering service for businesses that need custom AI software shaped around their workflow, not a generic template. The systems we build most often: voice AI receptionists that book appointments, qualify leads, and route calls 24/7; custom AI agents that handle research, document generation, data entry, and decision support; knowledge base search (RAG) over your documents and internal wiki; messaging AI for WhatsApp, SMS, and chat; API integrations connecting platforms that do not natively talk to each other. Engagements typically run 4 to 8 weeks, delivered by Armando and a small team with 18+ years of production software experience. Everything is architected to evolve as the underlying AI capabilities advance, version-controlled, documented, and handed over with full ownership.
Timeline

Best for
Businesses ready for AI-powered products and advanced automation
What you get
Everything in the box.
Each engagement is scoped and quoted up front, so the work is clear before we start.
- Technical discovery and architecture design
- Custom software build (TypeScript / Python / Node)
- LLM integration (OpenAI, Anthropic, or self-hosted)
- Vector database setup for RAG use cases
- Auth, logging, observability, and cost monitoring
- Documentation and runbook for your engineering team

Who it's for
Is this a fit for you?
Companies with internal data or domain knowledge that off-the-shelf tools cannot reason about
Teams building an AI-powered product feature
Businesses that need an AI agent tied to proprietary APIs or databases
Founders who need a trustworthy senior engineer, not a junior contractor
How it works
4 clear steps.
Architecture
We sketch data flow, model choice, and cost envelope before committing to a build.
Prototype
A working prototype in 1 to 2 weeks to de-risk the hardest part of the system early.
Production
Hardened build with auth, observability, retries, and cost controls. Deployed to your infrastructure.
Handoff
Docs, runbook, and optional ongoing retainer for improvements and new features.
What you walk away with
The outcomes.
Custom AI systems that speak your domain
Production-grade code, not notebooks or prototypes
Full IP and ownership, deployed to your cloud
Predictable LLM costs through caching and routing
FAQ
AI Integration & Development: questions we hear
- What qualifies as "AI integration and development" versus regular automation?
-
Regular automation connects tools you already have using off-the-shelf logic. AI integration and development is when you need custom intelligence: a RAG system that answers questions from your private knowledge base, an AI agent that handles a multi-step customer workflow, a voice AI that replaces a phone tree, or a custom model fine-tuned on your data. Timelines run 4 to 8 weeks, and pricing is quoted after a free discovery call.
- Do I need my own data to do RAG?
-
Yes, that is the point. RAG (retrieval-augmented generation) pulls from your documents, tickets, product docs, policy manuals, or whatever corpus you have. We handle data ingestion, chunking, embedding, vector storage (usually Pinecone or pgvector), and the retrieval pipeline. Typical corpus sizes are 100 to 50,000 documents.
- Is this production-ready code or a prototype?
-
Production-ready, with proper error handling, logging, monitoring, rate-limit handling, fallback paths, and deployment infrastructure (usually Cloudflare Workers, Vercel, or your existing cloud). Prototypes are faster and cheaper, and we will tell you up front if that is what fits the budget. We do not ship prototype code pretending to be production.
