Our core business is developing complex management systems, web platforms, custom SaaS solutions, browser extensions, mobile applications, high-load solutions through AI-Accelerated Development or as AI-Driven Products
What starts as software development often turns into something much
bigger. We help clients not only launch products, but improve
conversion, remove bottlenecks, test new ideas, and grow revenue over
time. For us, the real value is not in simply writing code, but in
helping the product perform in the real market.
That is why many clients stay with us for 3, 5, 10, or more years. What
starts as one project often grows into long-term cooperation across multiple
products and business directions. Over time, we become a reliable extension
of the client’s team, often acting as their own dedicated IT department.
Most of our new clients are referred to us by existing and long-term clients.

IT horror stories for Halloween 👻 The commit message says “small fix.” It changes 47 files. The bug disappears when you try to show it to someone. The legacy code has one comment: “Don’t touch this.” No tricks today. Treats only, please 🐈⬛ Happy Halloween 🎃

Our team visited a dog shelter 🐾 We brought a generator from the company. It turned out to be exactly what the shelter needed. We also bought several bags of food. Quality check passed: the dogs approved 😄 And of course, we spent time with the dogs. Lots of attention, lots of wagging tails 🐶

Do you know what your website or system runs on? On 21 October PHP released emergency fixes for two critical flaws that let an attacker run code on a server without logging in. Cloudflare and Amazon already report attack attempts. Node.js shipped its own security releases the same week. Every WordPress site runs on PHP. Updating WordPress or its plugins does not help here, because the flaws are in PHP itself. On a supported version the fix is a routine update to PHP 8.2.35, 8.3.36, 8.4.27 or 8.5.12, or Node.js 22.23.4, 24.22.1 or 26.12.1. Older versions are the harder case. PHP up to 8.1 and Node.js up to 20 no longer get releases, and the US cybersecurity agency CISA advises taking PHP systems on 8.1 or older offline until they are upgraded. Languages and frameworks publish the date their support ends. PHP 8.2 stops getting security updates on 31 December this year. A system that nobody has updated for a few years ends up on versions past that date, and often the owner learns it from a security fix the system can no longer get. Many owners we talk to would not know which versions their system is on. It was built years ago and works every day, and the developer who could answer has moved on. Moving off an old version takes more than one command. Code written for an older version often needs changes before it runs on a new one, so an upgrade needs planning. We start by checking what the system runs on and what depends on it. Then we update in steps and check after each one that orders and payments still go through. We have been building custom systems since 2005, and taking over systems someone else built is a normal part of that work. If you are not sure what your website or system runs on today, write to us at info@abz.agency and we will find out together.

It has been an absolute pleasure to work with the ABZ team on various challenging web technology based development projects. They are true professionals of the highest order and always deliver, as promised, on time and to the highest quality standards. ABZ has an excellent team of incredibly skilled developers, talented designers and effective product delivery managers who are able to take highly complex requirements and turn them into flawless products. Their internal organization is setup in a highly efficient way and our communication with them has been both frictionless and pleasant. It is rare to find a partner that is so trustworthy and reliable as ABZ has been on our projects. I can highly recommend ABZ to anyone who is looking for an excellent development partner and we hope to do many more projects with them in the future.
Working with ABZ agency is a real game changer for our project!
We went from complete chaos to order, we simply love their rules and processes, and we can see that they have spent years perfecting them to make collaboration the best it can be.
Often in projects, miscommunication is what causes a LOT of trouble (trust me, we wasted tens of thousands of euros in rework due to miscommunication, and that’s excluding the missed opportunity costs), and ABZ solves this issues with a few unorthodox approaches :
- No calls : this rule is amazing ! Scary, but amazing! We were anxious that it would be an issue but we haven’t had any problems, on the contrary, all the miscommunication that was happening with previous IT company due to lack of writing things down, is now gone! Everything is written, clarified, and findable again for later reference.
- No coding before requirements are clear : they ask a lot of questions, and when I see how clean their delivrables are, I am thankful for all their questions.
- Frontend starts in Figma : again, a great rule to avoid rework, design needs to be done 100% (for every single change) before frontend devs integrate it, there are no approximations, and the result is pixel perfect integrations!
We look forward to continuing to trust ABZ with the development of our project, and we’re very grateful for the attention and quality of service that they provide us with.
We’ve worked with ABZ on a number of projects - mainly Google Chrome Extensions. The work they’ve done has been exceptional. The projects we have worked on together have been complex and have involved integration with other systems involving APIs. The innovation, communication and quality for work has been excellent overall. Put simply, the guys at ABZ are some of the best developers. I’ve worked with in a 30 year IT career. I have super high standards but ABZ exceed them every single time.
