Web Development - SEO/GEO - AI-Ready Sites & Workflows - Hosting - since 1990
Digital solutions that work for you
Web development, applications and AI-enhanced workflows, with SEO/GEO and ad management for businesses that want to stay ahead. From Athens, for Greece and Europe.
The ecosystem
One identity, all your tools
You sign in once. One account, one central entry point, and from there you reach every app you have activated. No separate passwords, no remembering what belongs where.
One account
A single sign-in for Ekkremés, MS-Finance, LogicInvoice and the Support Portal. You connect to MS-Logic and the ecosystem recognizes you everywhere.
One balance of units
The assistant runs on units, shared across Ekkremés, MS-Finance and LogicInvoice. Buy them once, spend them wherever you like. The monthly units in your subscription are valid within the month; purchased units never expire.
Smart assistants
Every app has its own assistant, specialized in the work it does. The LogicInvoice assistant knows invoices and myDATA, the MS-Finance one knows finances, the Ekkremés one knows how to organize.
For individuals and teams
An organization has a shared pool of units. The administrator sees consumption per member and sets limits, while each member sees their own picture.
Your data stays yours
Hosted in the EU, no ads and no trackers. Payments are handled securely through Stripe, and every purchase issues a legal invoice.

SEO & GEO - Bring your project to the top
Organic visibility on Google, Bing and AI-powered search - so the right clients find you
From technical SEO to AI Overviews
Search is changing fast. Beyond traditional results, AI-powered answers (Google AI Overviews, ChatGPT, Perplexity) are rewriting the rules. I optimize your content so AI models cite you as a trusted source in their answers - we build your presence in both.

Testimonials
What my clients say
Before working with Michael I simply had no website. Now, both in Greece and abroad, everyone who sees it asks me who made it. He is always on time, and he often makes the changes that are needed on his own initiative. I can send my site anywhere and it represents me - it honours what I do. I would not trade him for anything.
I am completely satisfied with our collaboration with MS-Logic for the design and upgrade of my website. The result was a site that is more functional, more modern and more representative of my professional image, while my presence on Google improved significantly. What stood out was the professionalism, the consistency and the real knowledge of the subject. Our collaboration did not stop at delivery: every time I needed something, the response was immediate and substantial. I wholeheartedly recommend MS-Logic.
Support
AI chatbot, ticketing & client portal
I don't just deliver a site and disappear. My clients get organized support with an AI chatbot, a ticketing system and a client portal to see the status of their services at any time.
First-line AI chatbot
Instant answers to common questions 24/7, with escalation to a regular ticket when a human is needed.
Ticketing system
Every request becomes a ticket with a number, history and priority, so you always know where it stands and who is handling it.
Client portal
Access to a dashboard with your domains, hosting, maintenance services and task status - no more digging through emails.

FAQ
Frequently asked questions
How much does a website cost?
Development starts at 450 EUR for a simple presentation site. A complete, serious corporate site typically lands around 1,000 to 1,200 EUR. Depending on complexity, an e-shop or a custom application can exceed 3,000 or 4,000 EUR. All prices exclude VAT. After a short conversation about what you need, I give you a clear, detailed quote with no hidden charges.
How long does a project take?
A simple presentation site is completed from one week. A full corporate site takes a few weeks, while more complex projects such as e-shops and custom applications take 4 to 8 weeks. Timing depends on complexity and on how quickly we have the content, and we set a realistic timeline from the start.
What is GEO and why does it matter to me?
GEO (Generative Engine Optimization) is optimizing so you appear in AI answers (ChatGPT, Gemini, Perplexity). More and more customers ask AI instead of searching Google. If your site isn't properly structured, you stay invisible in this new, fast-growing channel.
What is the difference between SEO and GEO?
SEO aims to rank you higher in Google results, while GEO aims to make you the source the AI cites in its answer. SEO works with keywords and links, GEO with structured data (schema), content clarity and authority signals. In practice you need both: SEO for classic search, GEO for the AI answers that are rapidly gaining ground.
Do you take on sites you didn't build?
Yes. I take on the maintenance, optimization or rebuild of existing sites, after first doing an initial check of their condition.
Where are you based and who do you serve?
I'm based in Athens and work with clients across Greece and Europe. Collaboration works smoothly remotely, with clear communication at every step.
