Useful Guidelines

WordPress development has traditionally been built around a monolithic architecture: a single theme with a multitude of templates, features, styles, and scripts tightly woven together. This approach works well for most sites, but when a site becomes complex and needs to remain fast and scalable, it becomes a serious limitation. In this article, I’ll talk about what component architecture is, what it’s used for, its advantages and disadvantages, and how it doubled a team’s efficiency.

In today’s digital environment, most products and services are powered by financial models. That’s why there’s a growing need for clear, unified approaches to protecting such data. The Payment Card Industry Data Security Standard (PCI DSS) addresses this need—an initiative that companies around the world have been supporting and implementing since 2004 to minimize risk and combat financial fraud.

Every newly created system is unstable. Is it impossible to accept it or not? Remember the first airplanes — they were unreliable and, as a result, unpredictable. In 1903, the Wright brothers lifted their plane into the air for about 12 seconds. In 1908, one of the demonstration flights ended in the death of a passenger. At the beginning of the 20th century, accidents were commonplace. But everything has changed, and thank God.

Starting July 1, 2025, the voltage standard in the electrical network will officially change in Ukraine. What does this mean for consumers? Do I need to change my devices? And who is responsible if the voltage «jumps»? Let’s break it down point by point.

Since artificial intelligence has become part of workflows, teams have a new set of tools to work more efficiently. It would seem that under such conditions, management should become simpler and the quality of management should increase.

For a very long time, the specialization of a tester was positioned as the easiest and fastest way to enter IT. And still, some courses and schools periodically speculate on this issue. However, it has already become clear to many that everything is not so simple and unambiguous. In addition, artificial intelligence is developing rapidly, thanks to the tools of which certain transformations are also observed in the work of testers and approaches to the selection of candidates. Serhiy Romanov, a tester with over 15 years of experience who currently works for Ukrainian company Brightgrove, which collaborates with streaming giant Pluto TV, owned by Paramount Global, shared with dev.ua his observations on changes in QA, as well as tips on AI tools and examples of how AI can be used in testers’ work, which can both help and threaten.

Hello! This is Oleksandr Kryvotsyuk from «Just About Marketing», and in this article I want to share my own experience of building marketing in IT. Building a marketing department in an IT company is a complex process that requires a clear understanding of the industry, proper budgeting, and a strategic approach. Many companies simply don’t know where to start, which specialists to hire, and how much money to invest.

Since 2024, Ukrposhta has introduced the international practice of selling parcels that have been undelivered and unused for six months at auction through the Prozorro.Sales platform. The company explained how to participate in such auctions.

The digital era has opened up a lot of advantages for us: the ability to buy anything, anytime and from anywhere, instead of wasting time traveling. Now you can quickly order the desired item to your home. However, cyberspace is an environment in which you need to be constantly attentive, because scammers can take advantage of your carelessness and lure confidential information, and with it, money. So, let’s look at how to shop online safely: without financial and information losses.

If your business isn’t ranking on Google Maps, you’re not alone. Thousands of businesses face the same problem every day. But here’s the truth: getting to the top isn’t as difficult as it seems, as most of the top positions are occupied by businesses that are easy to bypass.

Whether it’s a new startup or a long-term project, internal or outsourced, in any IT project, the team starts with an estimate — it assesses the necessary resources, costs and deadlines. This can be done by various specialists: business analysts, sales managers, product and project managers, as well as direct task performers — developers, designers, testers, DevOps, etc.

Hello everyone! With you is Oleksandr Kryvotsyuk, SEM expert and author of the YouTube blog "Just About Marketing" . Today we are talking about SEO for IT companies: what works today? Let's analyze trends, recommendations, and a specific example.

Product scaling is like adolescence for startups. It’s painful, it’s uncomfortable, and everyone makes mistakes that are embarrassing to look back on. In my seven years of consulting at Movado, I’ve seen dozens of companies go through it. And almost all of them have fallen into the same trap. The main problem with scaling isn’t technology or resources. It’s that a successful MVP creates the illusion that adding more features will lead to even more success. That makes sense, right? It doesn’t. That’s the biggest pitfall of product development.

In a world of high competition, coordinated work with customers is one of the key factors of business success. This is why CRM systems exist — tools that help automate sales, improve customer service and increase the efficiency of the team. A few years ago, Ukrainian companies mostly used foreign software, in particular, hostile solutions from the country 404. Now more and more Ukrainian companies are choosing local CRM solutions, because they are not only adapted to the realities of the domestic market, but also offer profitable support, an intuitive interface in Ukrainian and flexible customization. dev.ua has collected the most popular and effective Ukrainian CRM systems — for small, medium, and large businesses.

Ten years ago, YouTube worked very differently. Subscribers were the main thing, because most views came from the subscription feed. Videos usually went viral due to attention on other platforms — Reddit or Facebook, not through YouTube’s algorithm. The system was like a podcast app: you only saw content from channels you were subscribed to. As the video gained popularity and people subscribed to the channel, the creator’s next video would receive many views from subscribers. YouTube would notice this and show the video to even more people, creating positive feedback.

For all women who are thinking about developing a career in IT, I would like to share my experience. My name is Natalia Burlakova, I currently hold the position of Senior Security Solutions specialist at Microsoft Central Europe, and this year will be the thirteenth year that I have been developing my career in a company that started with an office in Ukraine, and now at the level of European countries. I came to the company from the areas of marketing and sales to the position of a specialist in workplace solutions in the marketing team. I was very lucky, it was a time when cloud solutions were just entering the market. Few people knew what it was, so I learned along with the industry. Then I was more involved in sales, worked with large companies, with teams that solved technical problems for clients, and constantly learned. And today I already work in the technical direction, namely cybersecurity.

In a world where technology is changing at a breakneck pace, IT professionals have long ceased to be just technical experts. In 2025, soft skills will become no less important than knowledge of programming languages ​​or the ability to work with cloud infrastructures. Why is that? Because a successful career in IT increasingly depends on communication, adaptability, and the ability to work effectively in a team.

Маркетологи опинилися в новій реальності: користувачі дедалі частіше відмовляються від cookies, а законодавчі зміни в ЄС (на кшталт DMA) обмежують доступ до даних. У результаті рекламні системи отримують менше конверсій, що обмежує алгоритми навчатися і працювати ефективніше.
