New tech hits different
when you ship it.

Hi, I'm Roman. I build agentic AI systems.

AI that actually works in your business

Whether you already use AI or are just getting started, I identify where it adds value in your business and build it into your daily workflows.

How it works

1

Find the leverage

We look at how you work and where AI actually helps: what comes in, the decisions you make, what comes out.

2

Build

Each step becomes part of the system. The fixed logic sits in code, the judgment sits with the AI model.

3

Harden

Validation, error handling and your real data, so it holds up in practice and not only in a demo.

4

Deliver

Finished, branded output: documents, reports, decks, generated automatically and the same every time.

Best fit: agencies and companies that want to make complex workflows autonomous and repeatable, to save time, enable scale, and reduce operational load.

My projects

Agentic SEO Harness

AI workflow

A full SEO audit process built as an AI system, from the briefing all the way to finished, branded Word, PowerPoint and Excel reports. It runs as a Claude Code harness with its own data connections and a set of specialised agents.

Open sourceGitHubLive demo

An AI training coach built as an agentic multi-agent system: an agent is simply a Skill + a model. Capabilities are declared as modular Skills, each represented as a full SKILL.md folder (following the Agent Skills standard). A generator agent spawns an evaluator and iteratively refines outputs until an LLM-as-judge evaluation harness approves the result. With this coach, I cut my half-marathon from 1:39 to 1:28.

About

Roman Reinelt, Founder of RNLT Labs
Roman Reinelt
Founder

What drives me is working on the gaps most people ignore: repetitive work, broken workflows, inefficient processes and opportunities hiding in plain sight.

I enjoy the entire journey. Understanding the problem. Designing the system. Building it. Testing it. Shipping it. Taking full ownership from concept to launch and maintaining it over time.

Diving into emerging technologies early helps me understand how they can accelerate delivery and keep both my clients and me ahead of the curve.

Some of that work becomes products of my own. Some of it helps businesses replace hours of manual work with AI systems they can actually rely on.

Either way, the goal stays the same: find leverage, build the thing, and make it useful.
