CUSTOM WEBSITES AND ONLINE STORES. SEE FOR YOURSELF.
Custom websites from €1,250 and online stores from €3,000. Two engineers in Sofia, no templates and no agency in between. Here is how one of our sites shows up in Google.

Not a fluke. Three clients, three searches
The website paid for itself in five days.
Over €1,000 in bookings in the first five days after we launched atv-srednogorie.bg. Here is what they wrote themselves:
"They built us an incredible experiences website that started bringing us revenue within the first week."
To be fair, ATV Srednogorie came to us with a working business and well-kept social media. We added the website and the visibility. So five days is our record, not our promise. For most clients the first measurable results show up over the first few weeks.
Check us in 20 seconds
Open Google and search for any of the three: "атв турове", "младост 2 ресторанти", "лед екрани под наем".
Ask Gemini or ChatGPT: "Намери ми топ 5 компаниите за атв тур".
See who shows up. That is exactly what we do: a website plus optimization for Google and for AI assistants.
One caveat: our checks were run from Sofia, and Google positions and AI answers shift with where, when, on which device and how you search.

Two engineers. Zero middlemen.
No project managers. No account reps. You work directly with the engineers who architect and build your product - 12+ combined years in software engineering, cloud infrastructure, and AI. Strategy calls, design reviews, and launch support stay with the same people, so decisions are fast and accountability is clear. That boutique model is intentional: fewer parallel projects, higher craft, and personal ownership from first brief to go-live.

Custom website vs WordPress
In short: a custom website loads in under 1 second, scores 90-100 on Lighthouse, and has no plugin vulnerabilities or monthly maintenance. A typical WordPress site loads in 3-5 seconds, relies on dozens of plugins, and needs constant updates and upkeep. For a business in Bulgaria that bets on speed, security, and visibility in search and AI assistants, the custom approach wins.
| Criterion | Custom website | WordPress |
|---|---|---|
| Load speed | Under 1 second | 3-5 seconds |
| Lighthouse | 90-100 / 100 | Typically 50-70 / 100 |
| Security | No plugin vulnerabilities | Frequent plugin vulnerabilities |
| Monthly maintenance | Not required | Constant plugin updates |
| Design | Fully bespoke | Limited by the theme/template |
| SEO, AEO & GEO | Built in | Requires extra plugins |
| Hosting cost | Low (static / CDN) | Higher (PHP and database) |
| Scalability | High (headless) | Limited |
Custom website development in Bulgaria by Cognitex Solutions: typically 1-3 weeks for a website and 4-8 weeks for an online store.
How we engineer results
Audit & Architecture
We dissect your digital presence, map revenue leaks - slow pages, unclear offers, weak visibility - and design the technical architecture that will fix them first.
Custom Build
Every line of code is written by hand. Headless architecture when you need a store, custom storefronts, and clean integrations - built from scratch without template debt.
Performance Tuning
We optimize for sub-second load times, 90-100 Lighthouse scores where content allows, and conversion across mobile and desktop before launch.
Launch & Iterate
You go live with a system built for scale. Optional monitoring and retainers help evolve the platform as campaigns, catalog, and content grow.
Your website. Your choice.
If we part ways
The website stays yours. You own the full code of the website we build, the domain and the hosting account. You can continue with us or choose another team.
The full source code
You receive the website source code, not just access to the finished pages. It remains available to you for changes and future development.
Domain and hosting
Ownership and management stay with you. You control the domain and hosting account, including provider choices and renewals.
Accounts and access
You control project accounts, such as content management, analytics and Search Console where used. At handover, we clarify access, integrations and project data export if the site has a database or catalogue.
Who could take over?
We build on open technologies such as Astro and React, used by thousands of developers worldwide and in Bulgaria. Another qualified developer with experience in them can take over the website. The scope of documentation and transfer assistance is agreed in the proposal. External services, libraries and licensed assets retain their own terms and fees; ownership of your website does not transfer ownership of those software products.
Why write this at all? Because we are two people, and we know you are thinking it. You do not have to trust that we will still be here in five years. It is enough that nothing of yours depends on it.
You do not have to prepare everything alone
No website copy yet? We can help.
You know your business. We can write the copy and structure the content so visitors understand what you offer and how to contact you.
You share what you have
Send the photos, videos, logo, catalogues and other resources you have permission to use. Include information about your services, products, prices, team and contact details. You do not need finished copy for every page.
We prepare the content
We can write and edit the copy, select suitable materials from what you provide and organise them across the pages. If something is missing, we agree with you how to source it.
You review and approve
You review the copy and image selection before publication. You confirm that business facts, prices and claims are accurate, and we apply the agreed revisions.
What is included in the price?
The proposal sets out the scope of copywriting, revisions and additional materials. If new photography or video, paid stock assets or translations are needed, we first agree who supplies them and the budget. They are not assumed to be included automatically.
Testimonials
Hear what our clients say about working with us.
We paid the agreed price and got more than we agreed on. Our new site scores 100/100 on mobile in PageSpeed, and Zahari also built the English version without asking for anything extra. We went overboard with changes, and he took them calmly, without charging extra, and answered in the evenings and at weekends. On the very first day, a client told me he was impressed with the site without my asking. Work with him. A rare professional. I recommend him!

Precision, reliability and flawless execution! I am very happy with the final result. Fast and professional work. 5 stars!
The guys are great! They built us an amazing experience website that started generating revenue within the first week. These are true professionals who quickly learned our business and helped us add things we had not thought of. Working with them is transparent and flexible, communication is top-notch, and they are always available to help. We wholeheartedly recommend them if you are looking to get a website built, turn to them!
Working with them was extremely easy and pleasant - from start to finish. We didn't expect that an app could automate such a large part of our work and make things significantly easier. I highly recommend!
Thank you for a job well done! I am very happy with Cognitex Solutions. The site went live quickly, works flawlessly, and looks very stylish; they exceeded my expectations! The developer who built it clearly knows what he is doing and even contributed many great ideas and suggestions we implemented, and we definitely stand out in the market! Thank you!
