Lovro Bubanić · Founder of Neural LB

I build custom AI agents & productsthat are actually production-ready.

If you need a custom agentic system — not a ChatGPT wrapper, but something trained on your data, wired into your workflows, and built to scale — that's what Neural LB delivers.

ABOUT

Most businesses know they need AI.
Few know how to build it right.

I'm Lovro — the engineer behind Neural LB. I work with founders who need a technical co-pilot to ship fast, and companies that have an AI idea but no team to execute it.

With a background spanning full-stack development and AI engineering, I don't just connect APIs. I design the architecture, write the code, and ship a working product — not a prototype that falls apart in production.

Three focused offerings. Each one delivers something real.

Custom AI Systems

Agents and pipelines that know your business.

Custom RAG pipelines, LLM integrations, and AI agents trained on your data, products, customers, and context — built in code, not wrappers.

Langchain app with multiple AI Agents

AI Agents Article Debates

Langchain app with multiple AI Agents

A small Next.js app where multiple AI personas read an article you supply and debate it in turn—streaming replies in real time with a playful “agent window” UI (think classic chat bubbles, but draggable cards over the page). Built as a demo by Lovro Bubanic (“Neural LB”): paste a URL, extract the article, then let the agents argue, agree, or push back on each other’s takes.

AI Customer Support & Lead Gen Agent

AI Customer Support & Lead Gen Agent

A sellable, self-hosted web app: your customers talk to an AI on a public chat page, while you (the business owner) use a separate, private dashboard to view leads, upload business knowledge (text + PDFs), and see meetings the agent booked.

A full-stack web application that forecasts used and new vehicle prices over a five-year horizon.
