"I want a keynote or training"

When I had a €5M/yr business I automated a lot with AI.
Now? I automate businesses & train their teams how to use automation. 
If this is what you need, throw me a DM.

"I want AI automation in my consultancy business"

Recently, I've seen dozens of hour-saving-GPTs for:

- Writing complex offers (saved days every week)
- Writing social media captions (saved hours a week)
- Onboarding new team members (saved days a month)
- Making User Requirements Docs (saved days a month)

You can have that too.

The workflow is pain-free:

1. Survey
2. You send me docs
3. I build a concept GPT
4. Revisions until it’s perfect
5. Delivery in 14 days flat (or sooner)
... Plus: Satisfaction guaranteed.

Ready to stop wasting hours?

You are feeling overwhelmed because of AI, wanna know why?

Because:
- you don't know your processes well enough
- you haven't done a lot of automation
- and there's SO much info out there

So you don't know where to start.

And AI is a mess, because everyone's selling hype, lead magnets, or copy-paste prompts.

Who to trust?

That's where I come in.

I’ve been deep in AI since 2013.
I’ve built 50+ GPTs for founders across industries.
And 10K+ people use my free tools.

I help small consultancies and firms implement AI to fix operational headaches—without hiring more people.

Think:

→ Automating repetitive workflows
→ Building custom GPTs that reflect how your team thinks
→ Light MVPs that work for, and work inside your business
→ Training your team to USE the tools and become more efficient

As a founder of several businesses, I’ve seen firsthand what works and what’s just noise.

My approach:

1. Business scan
2. Problem solving
3. Creating tools (optional)
4. Focused training (optional)

That's when you start seeing results.

If you’re a founder or operator inside a consultancy that’s doing well (but your systems are clunky, your team’s stretched, and AI still feels like a maze) DM me “Scan” and I’ll show you where to start.

The Idealists

I worked on their dashboard app that allows parties involved - investors experts. specialists,
users, and admin - to engage With and develop approved ideas into new companies.

Learning Goals:
- Work on a pre-existing codebase and learn new technologies (TypeORM, Styled Components) on
the we go. while further developing our skills in the technologies we've already karned (see belch"
for all technologies used)
- Experience working on a real-world project With an client/product owner
- Practice using agile methodologies in a scrum setup to efficiently work and communicate with
team mates
- Plan our work realistically to be able to deliver each part on time
- Gain more experience working with version control and github collaboration. reviewing each
others pull requests solving merging conflicts.
We were presented with 4 user stories and a short list of •nice-to-haves" and given just two weeks
to get accustomed with the code and technologies used and to deliver a new set of features
implemented and deploy-able.

Due to the circumstances during COVID-19 outbreak we found ourselves working remotely with
teammates we previously' never met in person. We had to rely on Zoom and Discord for our daily
standups and put extra attention in communicating our progress. This is where our kanban project
became really useful allowing us to track our progress and plan towards a deploy-able MVP.

Despite challenges had a lot of fun working on this project and managed to deliver all features
requested in the user stories.

Technologies used:
Client: React.js, React hooks, Emotion CSS, Material simple-react-validator, cloudinary-react
