Websites
We never start from a template. First we understand your business, your customers and your goals. Only then do we design a site with a clear job — bringing in enquiries, selling, or building trust.
Ready in two weeks
A website built for the way you do business, live in a few weeks. No templates, no agency procedure, so you talk directly to the person building it.
We never start from a template. First we understand your business, your customers and your goals. Only then do we design a site with a clear job — bringing in enquiries, selling, or building trust.
Ready in two weeks
We build web and mobile apps for iOS and Android in React Native. We add product thinking to the development, so you do not just get working code but a product that makes sense to you and your customers.
An MVP within a month
We help you put AI and automation where it genuinely makes sense, saves time and simplifies daily work. We build AI assistants and agents, and set up automation around the work you already do.
An assistant is usually a matter of days
We write our own code, we do not assemble templates. The site is fast, holds together and can be extended later.
The look comes from your brand and from what your customers actually come to the site for.
Text that says plainly what you offer and leads the visitor to the next step.
It handles just as well on a phone, on a tablet and on a computer.
Structure and technical setup prepared so that search engines find the site and understand it.
Contact forms, booking, maps, social networks and the other tools you already use.
A simple screen where you edit texts, articles and other content without a developer.
Answers the questions that come up most and leads an interested visitor to an enquiry.
Half an hour to work out what you need, what the site is for and why. We set scope, timing and budget, and say what is worth doing and what is not.
A call within 2 days
We work out structure, copy and looks, then hand you a design we go through together and refine. Everything is agreed before development starts.
Design ready in 3 days
The approved design becomes a working site. Speed, responsiveness, SEO and the technical side are ours. Progress stays visible on a test address.
Development in up to 10 days
We test the site thoroughly, put it live and make sure it works as it should. After launch we stay reachable for fixes and further work.
Launch without waiting around

People choose a lawyer on trust, not on price, and the first impression is the website. We built the firm a site in three languages that shows which areas of law it works in, who will handle the case and what the first step looks like. Enquiries go straight to the firm’s inbox.

An independent agent without a site of their own exists only where a portal shows them: in a list beside dozens of others, where people choose by photo and price. We built an address of her own, with listings, Prague market data and consultation booking, in four languages.
Read the case study
Epilas does laser hair removal and device-based skincare in Žižkov. Two things decide a booking there: what a treatment costs and whether it suits the person asking. Until then both lived only on the phone. We built a site where it is written down, in Czech and in Russian.

Finding a flatmate in Prague happens in social media groups: dozens of posts, few replies, and nothing at all about the thing that matters, whether you can share a kitchen with this person. Roomble is our own product, and it flips the order: people and daily habits first, square metres after.
Read the case study
The permanent makeup studio had a site nobody could touch without a developer. Every price change meant an email and a wait, and online booking did not exist at all. We built a site the owner runs entirely herself, and enquiries from it go straight to Telegram.

„I am very happy with the result. We finally have a modern, working website in several language versions. Mr Ilja did an excellent job, and I also appreciate his flexibility.“

„I want to thank Ilja for building my website. I am genuinely very happy with the result. It mattered to me that the site should not just be pretty and modern, but reflect me: my style, my character and the way I work. Ilja managed to sense that and deliver it completely. I like absolutely everything about it: the visual concept, the colours, the typefaces, the photos, the way the sections are laid out, the details and the overall feel of the site. I want to mention the working process separately. At every stage he explained in detail what we were doing and why, showed me different options and helped me understand the technical side in plain, clear language. I never had to wade into things I am not an expert in: Ilja laid everything out, proposed solutions and made the whole process as easy as possible on my side. For someone who is constantly busy with her own work, that was especially valuable. All my wishes were heard, and Ilja could always advise how to do something better from a professional point of view. The result is a site I genuinely recognise myself in and am glad to show my clients. Ilja is a real expert at what he does, with an excellent sense of style and an eye for detail. Thank you for the professionalism, the patience and the ability not just to complete a task, but to truly hear and understand the client. I am very happy with our work together and I recommend Ilja with pleasure. ❤️“

„I want to say how satisfied I am with the way Rozenfeld kept their promise to build our site epilas.cz quickly and affordably. I particularly appreciate the approach of the director, Mr Neporada, who was willing to go through my comments day and night.“

„I did not expect it to be possible to have a website ready by the next day at a very pleasant price, and still have my new ideas added to it along the way. Ilja, you are a treasure.“


Founder & developer
Brings more than 7 years of building websites. From the first design through to launch your project stays with one person, so nothing is lost in a handover.

Copywriting & client care
Helps with copy, multilingual content, updates, small fixes and questions long after the site is handed over. More than 6 years with digital projects and long-term client care.
Did not find your answer? Write to us. We answer questions that never turn into a project too.
We settle on a figure after the first call, once we know exactly what you need, and we fix that price before work starts. No increases along the way or at the end.
You do not. We help with the copy and arrange the rest of the content where it is needed. At the start we go through together what you already have and what still has to be made.
Yes. We build on current technology and on an architecture that leaves room to grow. Readable code, content kept separate and documentation mean you will not be rebuilding the site in a couple of years. If you want to add something later, we simply extend it.
Yes. We can add AI assistants, chatbots and automation that answer customers, handle requests or take over routine tasks. Where it helps, we connect them to your own tools and processes.
One small change a month is included in the price of the site. If you want full control over the content, we can set up an admin area for you. Or you can leave the care to us: hosting, updates, monitoring, small changes and ongoing development. Maintenance starts at 1 100 Kč a month.
We build with search in mind from the start, both in search engines and in AI tools. We look after technical SEO, structure and content so that classic search engines and tools like ChatGPT can read the site correctly.
Write a few sentences about the project. Within 24 hours you get a first read on it and a suggested time to talk.
Whether you are still planning a new site or want to know what to improve on the current one, we will go through your needs and options with you and recommend what to do next.
