  • Integrate OpenAI/Claude APIs with a Next.js + Node.js backend
  • Vector search and RAG pipelines for your own data
What this service actually covers

Apps where AI isn't a bolted-on chatbot but part of the core logic — reasoning, decision-making, or multi-step action baked into the product itself.

Tech stack

React/Next.js frontend, Node.js/NestJS + PostgreSQL backend, Python for AI layers, LangChain and the OpenAI API for LLM orchestration, agentic frameworks for multi-step automation.

What "agentic" actually means here

Systems that can take a sequence of actions toward a goal, not just answer a single prompt.

Process

Discovery, architecture (where AI sits in the system, not just "add a chatbot"), build, integration testing, handoff.

Where this fits vs. plain Full Stack Development

This service is for products where AI is core to what the app does. Full Stack Development is for applications that don't need AI at all — see that page if that's a better fit.

The real difference

This page covers building new AI-native products. AI Automation (below) is about automating existing manual processes — different service, different starting point.

Real project
The ERP

One of the systems I built for an oil company is a good example of what "full stack with AI" actually looks like in practice, not just as a phrase on a services page. It started as a custom ERP covering every operation an oil company actually runs on — inventory, orders, procurement, workflow, internal notifications — and grew from there into a full automation layer sitting on top of that data.

Ecommerce + workflow

The ecommerce store sits on top of the same ERP rather than next to it, so an order placed on the storefront lands directly in the ERP's order queue instead of needing someone to re-enter it. From there, the workflow system takes over automatically — order confirmations, internal approval steps, and stock-level checks all fire without anyone touching the order by hand, and the email system sends the right notification to the right person at each step, customer or internal team, instead of someone drafting and sending it manually.

The AI chatbot

The AI piece is an internal chatbot layered on the ERP's real data — someone on the team can ask it what's low on stock, how many units of a product are currently in or out, or what needs reordering, and get a real answer pulled straight from the actual inventory numbers instead of digging through a dashboard or asking around. Between the automated workflow, the automated emails, and the chatbot answering questions on demand, most of what used to be someone manually checking, deciding, and following up now happens on its own.

FAQ

Common questions

What's the difference between AI automation and AI full-stack development?

AI Full-Stack Development builds new products with AI as core architecture. AI Automation replaces manual work in processes you already run.

Do you build the AI model, or integrate existing models like OpenAI's?

Existing models (OpenAI, Claude, etc.) via API integration — not training models from scratch.

Can AI features be added to an app I already have, or does it need to be built from scratch?

Both — AI features can be added into an existing app or built into a new one from the start.

What does "agentic AI" mean in a real product, not just marketing language?

A system that can take a sequence of actions toward a goal on its own, rather than just responding to a single prompt.

How do you handle AI costs (API usage) at scale?

Usage patterns and cost controls are part of the architecture discussion up front, not an afterthought after launch.
