Happy 65th Independence Day Cyprus!

As a Dutch native, I feel honoured to call this resilient island my home as it marks this historic milestone.

Wishing everyone a great celebration.

Very interesting article for anyone interested in the use of AI in education.

IMO domain-specific AI models instead of generic trained ones are essential to address many of the challenges mentioned and to effectively address concerns like feedback, bias, context, etc.

What's your opinion?

That said, we need to go further. IMO, domain-specific AI models are essential to address many of the challenges you mention and feedback, bias, and context.

Appreciate you sharing this — it’s an important and well-reasoned piece, and I agree with most of the concerns raised around AI in education.

I believe agentic AI, when grounded in Self-Determination Theory and constructivist principles, can help learners reclaim both autonomy and integrity.

Decentralized education is what got me passionate about Web3. Agentic AI was the missing link to make it truly decentralized.

So it should surprise no one that when I started @synthonyx.com, #EdTech became a core mission.

I’ve lived in 5 countries, including nearly a decade in a remote Bulgarian village (Slavovitsa, Pazardzhik). I enjoyed that more than any city.

Let’s see what life in a #Troodos mountain village will bring. Can’t wait!

One year in #Cyprus already!
When I arrived, the plan was: one year by the coast, one year in the mountains — then decide where to settle.

Tomorrow, I make the move to the mountains.

Curious how others approach language learning:
Do you start with grammar? Vocabulary? Listening? Full immersion?
What’s worked—or totally failed—for you?

Let’s share methods.

Instead of spreading verb tenses, moods, and aspects across multiple levels, I learn them all at once.

It works. Because it’s not about memorizing silly sentences—it’s about understanding the system behind them.

That’s why I go grammar-first. Once I understand the engine—tenses, syntax, structure—everything else starts falling into place. Vocabulary sticks better too when you know where it fits.

The CEFR focuses too much on memorizing situations—like how to order a coffee—instead of teaching you how the language actually works.

Why learn words if you don’t know what to do with them?

Hello fellow language learners! Let’s talk about how you learn languages.

I’ve lived in five different countries and always learned the local language. Now I’m learning Greek.

But I’ve never been a fan of the CEFR system (A1–C2) for learning languages. 🧵

Interesting to hear Musk talk about a US–EU free trade zone. That was actually the goal of TTIP, which aimed for zero tariffs and better regulatory alignment.

But the first Trump administration shelved it—Trump preferred one-on-one trade deals.

Funny how we’re back at the same idea full circle.

Follow for no-fluff insights on token design, startup execution, and web3 that actually works.

Tokenomics is the economic layer — incentives, supply, utility.
Token Engineering is the discipline behind it — modeling, simulating, pressure-testing the whole system.

It’s also not just tech.
It’s applied complexity science.

Real builders don’t just design tokens — they engineer economies.

If you’re designing a token or investing in someone who is, read this:

I wrote a deep-dive on why inflation-based tokenomics are not only valid, but might be the best choice for serious utility networks:

✔ Debunks the Bitcoin-maxi logic
✔ Breaks down Polkadot’s model
✔ Compares fixed vs inflation side-by-side
✔ Shows how good inflation = ecosystem growth, not dilution

Most founders still treat tokenomics like marketing — Make it sound good, pump the hype, and hope no one asks hard questions.

But if you're building real utility… You need an economy, not a collectible.

I only take 2 sprint clients per month, so we move fast.

Founders bring me in when it’s too early for a full-time CTO — but too risky to keep guessing.

It’s cheaper than one bad hire.
It’s faster than dragging through chaos.
And it sets you up to scale with clarity.

This is why I introduced 10-day CTO Sprints — short, focused, high-leverage engagements that:
• Audit your tech direction
• Define your execution plan
• Align founder vision with delivery reality

Clear output. No long-term lock-in.

When does CTO-as-a-Service make sense?
✅ You’re building an MVP
✅ You’re fundraising but tech is a question mark
✅ You’re stuck between freelancers, no roadmap, and growing chaos

This is where a sprint changes everything.

A fractional CTO saves you from:
💸 Overspending on wrong tools
🧱 Scaling too early
🔥 Hiring too fast
🌀 Devs building without direction

It’s risk management for your tech stack and your sanity.

You don’t need a “co-founder” to fix that.

You need a fractional CTO — someone who:
✅ Understands startup velocity
✅ Aligns tech with vision
✅ Calls out BS before it ships
✅ Builds systems, not spaghetti

Founders without a technical background often make the same brutal mistakes:
• Hiring devs before defining the architecture
• Outsourcing the MVP to a black box agency
• Overbuilding to impress investors, not users

It’s not stupidity. It’s a blind spot.

Most early-stage founders don’t need a full-time CTO.

They need a co-decider who understands tech.
They need CTO-as-a-Service.

Here’s when it makes sense — and how it prevents €100K+ mistakes 🧵

If your product doesn’t have users, it’s probably not a marketing issue, but a UX issue.

→ UX drives adoption
→ Adoption builds retention

Most techies (myself included) suck at UX.
But that’s no excuse to ignore it.

Bring in someone who gets it.
UX isn’t polish — it’s survival.

COBOL isn’t killing innovation.
You just don’t understand what it is.

Not a legacy GPL — but a rock-solid DSL for business, still running the core of banks, insurance, and governments.

Mainframes aren’t dying, but evolving. And rewriting #COBOL “for innovation” is how real tech debt gets born.
