Ukrainian tech entrepreneur, backend and AI engineer Igor Karas announced the relaunch of his technology service Rail-X, which helps drivers receive information about the status of railroad crossings in real time and make route decisions.

Ukrainian startup FPV Battleground has created a combat FPV drone simulator that has already sold over 10,000 times on Steam, with about half of the users coming from outside Ukraine. The game simulates real-world scenarios for using FPV drones on the battlefield: the operator must find a target, take into account the effects of electronic warfare, and execute an attack. The simulator is available on Steam and the Epic Games Store. The civilian version costs $10, and the developers provide free keys for military users. The project is also entering the international startup scene: the FPV Battleground team made it to the top 20 of Founders Battle at the TechChill technology conference, where they are presenting the product to investors.

The Ukrainian market has been operating in a full-scale war for five years, and the IT industry is no exception. If earlier the choice of a cooperation model between an individual entrepreneur, a gig contract, or a staff was mostly a matter of taxes and flexibility, today it also determines the legal status of a specialist during mobilization. There is still a misconception on the market that a gig contract gives the right to an official deferral for a specialist, but in fact it does not provide for such guarantees, since it is of a civil law, not a labor nature. As a result, a paradoxical situation arises: some IT specialists who previously chose flexible models of cooperation are now asking to be transferred to the staff under the Labor Code. What is the difference between a gig contract and an employment contract, what are the nuances of working on a staff, and how are companies changing the model of cooperation with teams today? Let’s figure it out in order.

Microfinance organizations in Ukraine provide small, short-term loans, mostly online and through a simplified procedure. Despite the speed of processing, it is important to carefully check the lending conditions, the real cost of the loan, and possible risks before concluding an agreement to protect yourself from financial complications.

Volodymyr Yushchenko, a 23-year-old from Kyiv, is developing an app called SlixOne that helps people find company for a vacation in real time. The project is designed as an alternative to traditional dating services, focusing on going to bars or going for walks together. We talked with Volodymyr about how the idea for the application came about, how much money was invested, and at what stage of development.

We’re sure you’ve received it too. Letters about «expired SSL,» «urgent request from the SBU,» «immediate contract renewal,» or even that «everything will be blown up.» Some of them are so ridiculous that you can’t help but smile. Some are much more cunning and make you take a closer look. Together with the De Novo cybersecurity service, we analyze the most common cases of phishing and «happiness letters» from creative scammers.

To begin with, I want to explain what exactly voice agents can do? The same as text agents, but with voice? And in principle, globally it is, but with the only clarification that voice agents have additional functionality — to make calls and have a conversation, and this opens up additional value for your business.

Most IT professionals who get paid in USDT do the same thing: withdraw to fiat and forget. The logic is clear — a stable currency, a clear exchange rate, minimal headaches. But it is at this point that money stops working.

Many people have answered a call from an unknown number at least once and heard silence on the phone. Sometimes the person you’re talking to appears only after a few seconds, and sometimes the conversation never begins. In fact, this could be part of a scam designed to verify that the number is active and that a real person is answering it, Shane Barney, director of information security at Keeper Security, told ZDNET.

Tens of billions of dollars per month — this is exactly the amount of money, according to Vladyslav Vlasyuk, the Presidential Commissioner for Sanctions Policy, that Russia is «driving» through cryptocurrency in order not only to circumvent the economic sanctions imposed on it, but also to purchase components for its weapons in Europe, the USA, and other countries of the Western world. This problem is very acute. How exactly are Ukraine and the EU fighting it? Vladislav Vlasyuk told about this and more in an interview with dev.ua. Also read about whether a complete «ban» of cryptocurrency trade with Russia by Europe is real, how many cryptocurrency exchanges are under sanctions, and how unknown «well-wishers» and special services are helping to unravel the chains of cryptocurrency connections.

Global oil prices exceeded $100 per barrel for the first time since July 2022. Brent (the global benchmark) rose to around $107–108 per barrel, US WTI to around $106 per barrel.

For a B2B platform in iGaming, every scaling means new integrations: game providers, payment services, KYC, local regulatory requirements. In such a dynamic, the architecture quickly becomes overgrown with exceptions. «Without standardization, each new partner or jurisdiction requires separate custom solutions — in logic, integrations, reporting, access. Instead of a unified architecture, exceptions appear in the code and dependence on a specific market,» explains SharksCode CTO Igor Morgunov. The team faced a typical industry challenge: in the short term, customization speeds up launch, but in the long term, it makes the system fragile. A solution was needed that would discipline the architecture. GLI-19 certification was that solution.

Communication in Ukraine is noticeably becoming more expensive. And there are no surprises here. The wave of price increases swept through at the end of last year. And in the first months of 2026, all three mobile operators announced tariff increases.

On March 4, Iran used drones to strike an Amazon data center in Bahrain, citing its desire to “determine the role these centers play in supporting hostile military and intelligence operations.” The very next day, the United States and Israel retaliated by striking at least two data centers in Tehran, according to local NGO Holistic Resilience. Earlier, on March 1, the tech giant’s cloud unit, Amazon Web Services, was forced to report a temporary power outage at its Dubai data center due to hostile fire — and a resulting fire. In these few days, the world has finally realized what Ukraine has been saying for years - generally accepted security standards for data centers are hopelessly outdated.

Imagine the morning scene: you open your closet, look at dozens of things — and again catch yourself thinking that you have nothing to wear. Even though in reality your wardrobe is full. It’s just that most people wear the same combinations for years. Ukrainian developers decided to transfer this task to artificial intelligence. They created the smart.outfit.ai application — a «pocket stylist» that analyzes the items in your wardrobe, suggests new outfits, and helps you combine clothes right on your smartphone. dev.ua talked to the startup’s founder, Dmytro Balyuk, and analyst Kateryna Kravtsova about how their AI works, why hundreds of gigabytes of clothing images are needed to train models, how much the product development cost, and why the team does not plan to attract venture capital.

In September 2025, an ambitious question was posed: is it possible to create a new abstract concept — and have Google recognize it as a separate entity in its Knowledge Graph? No Wikipedia. No classic PR campaign. No mentions in major media. Thus began an experiment with the «Artifact Marketing» methodology, an approach that can be considered part of the new practice of Generative Engine Optimization (GEO).

On Reddit, IT professionals from all over the world are actively sharing their projects created with the help of AI. We have collected for you a selection of developments that relate specifically to workflows. Perhaps these tools will be useful or inspire your own ideas.

Pet-проєкти, open source та фриланс-досвід давно стали частиною ІТ-резюме. Для одних це спосіб увійти в професію, для інших — можливість прокачати нову технологію. Але чи реально рекрутери зважають на цей досвід під час найму? І чи бувають випадки, коли саме він стає вирішальним? dev.ua запитав про це представників EPAM, SoftServe, Ciklum, Railsware, Intetics, PlantIn, Mate academy та Pingle Studio. Загальний висновок — так, звертають увагу. Але значення такого досвіду сильно залежить від рівня кандидата та контексту ролі.

Ukrainian business has undergone tremendous transformations in recent years. Companies have learned to work in conditions of complete uncertainty, quickly adapt to changes and, most importantly, to calculate their own resources much more carefully. In this new landscape, it has become obvious: marketing can no longer be just an auxiliary function that «runs advertising» or manages social networks. Today, marketing is the foundation of business strategy, which directly affects the company’s revenue, stability and ability to scale.

After the start of the war in Iran, the oil market opened higher, but without the expected panic. On Monday, quotes rose to $82 per barrel, compared to $72 on Friday. This was announced by Serhiy Kuyun, director of the A-95 consulting group. According to him, investment bankers traditionally predicted scenarios of $100–150 per barrel, but the market reacted much more restrainedly.

In the last week, the world’s attention has once again been focused on Iran and the Middle East in general. After another wave of mass protests and their bloody suppression in January, the situation in the country began to develop even more rapidly and unpredictably in late February. On the last day of winter, after a series of military strikes by the United States and Israel, the death of Ayatollah Ali Khamenei, who had ruled the country for almost 40 years — since 1989 — was officially confirmed. The day before, it was reported that his son Mojtaba had taken over power.

dev.ua spoke with the teacher of a team of tenth-graders from the Polytechnic Lyceum «KPI», who became finalists of the Ukrainian Teens in AI 2026 selection and created Speachie, an application for training communication and preparing for interviews.

Hello! This is a fresh special on the dev.ua channel. I hope you are ready for the wave of useful information that will happen right now.

Vibecoding is a term that Andriy Karpaty introduced in early 2025. The idea is simple: you describe what you want, AI generates the code, and you adjust the result. You don’t write the code, you manage it. Since then, the internet has split into two camps. Some say, «This is a revolution, we don’t need coders anymore.» Others say, «This is a toy, you can’t build anything serious on it.» Both are wrong. I’m a product designer with a background in UX/UI. Not a front-end developer, not a full-stack developer. But over the past year I’ve released several working projects written mostly through AI-assisted development. One of them is a time tracker for freelancers — I put together in one day. From idea to deployment. And it works.

Modern cybercrime operates as a full-fledged industry: viruses are sold on subscription, and stolen accounts are a regular commodity on darknet marketplaces. Dima Ashkinazi, founder of leak monitoring service Alerts Bar, explains what this ecosystem looks like from the inside. From info-stealers who quietly collect data to brokers who resell corporate access. In a conversation with dev.ua, Dima tells why even antiviruses and 2FA often don’t save, how the «golden window» works after a leak, and how the incident with the compromise of a top manager’s account, discovered by his team, helped Oracle close the risks in time and avoid potential losses.

A large-scale conflict has erupted in the United States over the use of artificial intelligence in the defense sector. At the center are OpenAI, Anthropic, their flagship models ChatGPT and Claude, as well as the United States Department of Defense. The story has already gone beyond the corporate dispute — it is affecting the AI ​​market, federal contracts, and the public debate about the limits of military applications of artificial intelligence.

American academic standards, industry-based faculty, international scholars, and a vibrant IT community — this is what a master’s degree for engineers at American University Kyiv looks like today. Serhiy Tytenko, Deputy Dean of EPAM School of Digital Technologies and Associate Professor at American University Kyiv, talks about the philosophy of the Master of Software Engineering program and its real benefits.

At work, we have long learned to count almost everything: hours, KPIs, deadlines, burn rate, velocity. And we also seriously talk about productivity, mental health, burnout. But at the same time, physical condition often remains a «side effect» of work, not a part of it. It is generally customary to optimize processes, but the body remains out of sight as a resource, although it directly affects cognitive and creative workload. And both the person himself and the business as a whole, for which he works, pay for this.

At the end of 2023, HR in the IT sphere Anastasia Sokhatska left her position at SoftServe to establish her own charitable foundation to help the military. 9 years of her IT career were left behind, and new, previously unknown, challenges arose ahead of her. In early 2026, 2.5 years after the launch of the 1991 Charity Fund, the fund closes tens of millions of dollars in funds, providing defenders with transportation, drones, NRCs, and other equipment, as well as supporting «drone workshops» at brigades and helping veterans.

This year marks a point where several technology trends are beginning to intersect. AI agents are entering the economic space, RWAs are moving real-world assets onto the blockchain, and the development of 6G is preparing the infrastructure for the future economy. At the center of this transformation is the cryptocurrency architecture, which is becoming invisible and ubiquitous. How exactly they converge and what this will lead us to in the coming years is in this article.
