Which technologies do you work with?

We work only with our own stack: PrestaShop, Next.js, Ruby on Rails and React Native. Stores on other platforms, such as WooCommerce or Shopify, are migrated to our stack.

Can you take over my existing store?

Yes. We start with an audit across Shops, Security and SEO. Then we migrate your store to our stack and to servers we manage directly, and take over full care. From then on you have one contact for everything related to your store.

Why only your own stack and your own servers?

Because only then can we take full responsibility for your store. We know every part of it - from the code to the server - so we react faster, optimise more effectively and never send you to third-party providers.

What does security care include?

It includes hosting on servers we manage directly, regular platform, module and server updates, backups with a recovery plan, uptime and incident monitoring, and protection against attacks. We react before you notice a problem.

What is visibility in AI assistants?

More and more customers ask AI assistants such as ChatGPT, Gemini or Perplexity about products instead of typing into a search engine. We make sure your store is easy for them to understand: we organise the content structure, implement structured data and prepare information that AI can cite.

How much does it cost?

It depends on the scope. After the call and audit you get a written plan with scope, timeline and budget - with no surprises.

Our promise

Full responsibility for your store.

We don’t send you to your hosting provider, a developer or “the SEO person”. If it concerns your store, it’s our job.

Who it’s for

Small and medium businesses without an in-house IT team

We work with companies whose online store is an important source of revenue but that don’t have their own IT department.

Sounds familiar?

Your store runs on WooCommerce, PrestaShop, Shopify or a similar platform.
Hosting, a developer “every now and then”, an SEO agency - and nobody takes care of security.
When something breaks, everyone says it’s “not our department”.
You’d rather focus on products and customers than on servers and updates.

What we change

If it concerns your store, it’s our job.

“Not our department”: “It’s our job”
Nobody takes care of security: Security by default
Servers and updates: Time for products and customers

The challenge

An online store is three challenges at once.

A store that doesn’t sell

A slow store, a clumsy checkout and abandoned carts cost you customers every single day.

Risk

Attacks, data leaks and downtime can stop your sales at the worst possible moment.

Invisibility

Customers can’t find your store in search engines or AI answers, and every paid click costs more and more.

Usually three different companies handle them. With us, all three are in one pair of hands.

Three pillars

Shops · Security · SEO

The three sides of our mark are three pillars. Each one strengthens the others, and together they lead to one goal: sales.

01 / 03

Shops

Stores that sell.

A fast, convenient store designed for conversion and developed together with your business.

What we do

Conversion-focused UX/UI design
Stores built on PrestaShop and custom solutions in Next.js and Ruby on Rails
Mobile apps for stores in React Native
Integrations with payment providers, couriers, ERP systems and marketplaces
Migrations from other platforms to our stack
Full care, development and optimisation after launch

Result: A fast, convenient store, ready to grow.

02 / 03

Security

Secure.

Updates, backups, monitoring and protection against attacks. We react before you notice a problem.

What we do

Hosting only on servers we manage directly
Regular platform, module and server updates
Backups and a fast recovery plan
Uptime and incident monitoring
Attack protection and security audits
GDPR compliance support

Result: Safe customer data and uninterrupted sales.

03 / 03

SEO

Visible.

Technical and content SEO that helps customers find you - not your competitors - in search engines and AI assistants.

What we do

Technical SEO audit
Visibility in AI assistants: ChatGPT, Gemini, Perplexity
Performance optimisation and Core Web Vitals
Category and product page structure, structured data
Content that search engines and AI like to cite
Analytics and clear reports

Result: Customers find you in search and AI assistants - not your competitors.

Our stack

PrestaShop
Next.js
Ruby on Rails
React Native

We work only with these technologies and only on servers we manage directly. Stores on other platforms are migrated to our stack and our infrastructure.

AI in practice

We work with AI every day, so you benefit from it first.

For us, artificial intelligence isn’t a buzzword - it’s an everyday tool across store development, security and SEO. That’s why our clients are the first to benefit from the AI revolution instead of catching up with it.

Faster

New features, fixes and content reach your store in days, not weeks.

More vigilant

AI helps us catch bugs, threats and drops in visibility earlier - before your customers notice them.

More for the same budget

We automate repetitive work, so your budget goes into growing your store, not into routine.

AI is not an autopilot

Behind every AI tool stands a responsible team.

AI is only as good as the people steering it. We follow this technology as it evolves, test new solutions before they reach your store and review everything AI produces. Responsibility for the result is always ours.

Why ANTCZAK

No “not our department”

Store, servers, security and SEO in one pair of hands - on our own stack and infrastructure. If it concerns your store, it’s our job.

Security by default

Security isn’t an add-on to the quote - we build it into every project.

Clarity and transparency

A clear scope, timeline and reports that anyone can understand.

Big-player quality without an IT team

We give small and medium businesses the technology and care that used to be reserved for the biggest players.

Who’s behind it

A real person behind every store.

Bart Antczak

Founder · Tech Lead

Since 2018 I’ve been building and growing digital products. I’ve launched more than 30 of them - from large, high-traffic online stores to AI-powered tools. I don’t stop at writing code: I look at a store as a whole business and streamline processes so that technology actually drives sales.

Outside work I race triathlon. I finished my full-distance debut - IRONMAN Italy Emilia-Romagna in September 2026 - in under 10 hours: a 3.8 km swim, 180 km on the bike and a 42.2 km run. I approach projects the same way I approach a race: a solid plan, consistent work and determination all the way to the finish line.
