“This is already a must-have, there are already cases where engineers are asked to write online coding prompts during interviews,” is one of the comments we saw on LinkedIn. It was written by Software Developer Viktor Svertoka after discussing such cases with colleagues during a meeting at the DOU Day IT conference. So we decided to ask team leaders whether they practice such a task, and vice versa — we asked developers whether they have encountered such a requirement. In addition, we monitored vacancies on jobs.dou to check how often employers require candidates to have such a skill. Here is what our small study showed.

Blockchain is a distributed ledger of data, the main feature of which is its complete independence from any centers. At the heart of this independence is cryptography, which ensures the authenticity and immutability of records, as well as decentralization, which eliminates the need for a central management body. But while the concept of encryption is understandable at a basic level, the question of implementing the second mechanism remains a mystery to most people.

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.

Over the past few decades, Ukrainian women have proven that their place and role in the domestic IT sector are beyond doubt. If we take the statistics from February 2024 to February 2025, then among new IT entrepreneurs, women generally made up 48%, almost embodying the same gender equality in practice. But is there a place in Ukrainian IT for purely female projects, which, moreover, declare themselves on the market with a slight touch of shocking? The girls from Sisi.Dev prove that yes. We spoke with Founder and Project Manager Yulia Mazhaeva, Co-founder and Head of UI/UX design Khrystyna Moroz, and Business Development Manager and Marketing specialist Alena Kukhtina to understand what services Sisi.Dev provides, what domains they work with, and what it’s like to run a women’s business during a full-scale war. In a conversation with dev.ua, they also told us how it all started, what business development plans they have, and how customers are reacting to their somewhat provocative «sign.»
