Світло є, а інтернету немає. Як підготувати зв’язок до тривалих відключень
Ukrainians have already learned to prepare well for power outages: power banks are charged, flashlights are in an accessible place, some have a charging station, some have a generator.
But there’s another system that we often only think about when it stops working: communications. And the latest attacks show that the problem today is not just the lack of electricity.
Russia is not only attacking energy infrastructure. Data centers, communication nodes, provider equipment, and other elements of digital infrastructure are also under attack.

"Get Internet by the bucketful." Or why Russia is risking much more by raising the stakes through strikes on telecoms
“Get internet in buckets,” jokes Mykola Andrushchenko, marketing director of the Lanet network, on his Facebook page. Dark humor, Mykola. But funny. Thank you! In Kyiv, what I personally feared the most (regarding the destruction of infrastructure by the Russians) is beginning - hitting telecom sites and data centers.

A new social network, MoodiMix, has been launched in Ukraine. Users receive rewards for their activity, and their profile turns into a game character.
The story of the creation of the new social platform MoodiMix began as an ordinary student project of two friends who wanted to spend their summer vacation usefully. Today, it is a full-fledged product with a clear vision, where every user action turns into progress, and their own profile takes on the features of a game character. The main feature of MoodiMix is the introduction of gamification into the usual process of social interaction. The platform allows users to not just consume content, but to experience constant development thanks to the XP system, level accumulation, and deep page customization. MoodiMix founder and Fullstack developer Vlad Goncharenko told dev.ua how he created the project, what technologies he used, and how he plans to develop the social network further.

Where is banking for Ukrainian export business heading?
Over the past 10 years, the number of financial solutions available to Ukrainian businesses abroad has increased many times. But the number of quality solutions — those with which you can really build an operating system — has grown much less. I have been observing this gap from the inside for over a decade: first at Payoneer, where I actually built the Ukrainian direction from scratch, and now at Solidgate Treasury , where we are building banking specifically for the profile of such a client — accounts with European IBANs, multi-currency operations in USD/EUR/GBP, SEPA/SWIFT transfers, mass payments to contractors, and corporate cards for distributed teams. And this gap is not a temporary nuisance, but the result of where the entire fintech market is heading.

From "hardware under the table" to AI factories: The history of the independent Ukrainian cloud
Independence in the 21st century is measured not only by borders and the army, but also by the ability to preserve one’s data, digital statehood, and business during the largest systemic crises. What do you know about the Ukrainian cloud? How did the first and largest national cloud providers and mass services appear and grow? How are they changing right now under the influence of artificial intelligence? And most importantly, how does the cloud hold the foundation of our digital sovereignty?

A digital copy of yourself and the dream of "doing nothing." A great interview with Artem Borodatyuk about life and business
Imagine a boy who buys firecrackers at the legendary 7th kilometer in school, prints business cards “Artem, student of grade 5-B” on an old printer, and sincerely believes that business is when you have your own business card and an office with a study. Then this boy grows up, works without sleep for weeks until his nose bleeds, accidentally creates one of the most famous IT empires in the country… and at some point realizes that his main dream is to simply do nothing. Sounds like the plot for a teenage bestseller about growing up? But this is the true story of Artem Borodatyuk, founder of Netpeak Group and Fractal. In the first major video interview for dev.ua in a long time, we decided to strip away all the corporate gloss from the business and talk about what's really going on in the founder's head.

Migrating a high-load service without downtime: how to synchronize data, maintain compatibility, and anticipate reverse migration — SharksCode experience
When a service runs 24/7 and has external and internal consumers, there is virtually no window for maintenance. This is the task that the SharksCode team faced when migrating a high-load backend component along with its data layer to a new infrastructure and a new data storage scheme. The old implementation began to limit scalability and make it difficult to scale the read and write load independently. Meanwhile, any schema changes and releases were becoming increasingly risky. The company was preparing the system for further growth and wanted to do it without a single minute of downtime.

More sales without new traffic: how to accelerate deals in the funnel
When a business wants more sales, the first reaction is often the same - increase traffic. But I wouldn't start there. Just look at what's happening with the deals that are already in the funnel. This is where the reserve for additional sales is. And for this you don't need to increase the flow of leads. Next, let's look at what can be done to make deals move faster.

Hype and hate on Threads. Where does the influx of fake pages of Ukrainian companies come from on this social network and can evil "doppelgangers" ruin the reputation of top brands?
The social network Threads quickly acquired a special vibe and became popular, including among IT professionals, as a platform where you can relatively easily get the attention of the audience, especially if you don’t skimp on words and are able to generate bright, and sometimes provocative, content. The press services of famous Ukrainian brands have long begun to compete on Threads with their own wit, making memes and poking fun at their competitors. But over time, the social network has also become filled with their brutal and ill-mannered “doppelgangers.”

Banner blindness is costing brands money: why your ads may be overlooked
In 1994, the AT&T banner appeared on the HotWired website, making it the first web banner ad. It was clicked on by 44% of those who saw it—nearly one in two, recalled the ad’s co-author Joe McCambly. By today’s standards, this is an exceptional result. For comparison: in a July 2025 article , Semrush notes that the click-through rate for display advertising often falls below 1%—less than one click per hundred impressions.
But already in 1997, three years after the launch of the AT&T banner, researchers at the Nielsen Norman Group described banner blindness — the tendency for users to ignore elements on a page that look like advertisements.

When will TAF Industries drones sail and deepstrikes fly to Russia? A big interview with CEO Volodymyr Zinovsky about new partnerships and developments, deftech problems and competition for valuable specialists
TAF Industries has long established itself as a leader in the production of FPV drones, and its "Kolibri" "birds" are among the most popular on the front. But the current ambitions of the group of companies are much broader — its product line already includes NRCs, and water drones are to be added soon. Thus, according to CEO Volodymyr Zinovsky, TAF Industries' unmanned solutions will cover all domains — air, land and water. It is also planned to produce middle strikes, deep strikes, high-speed interceptors and new reconnaissance aircraft in addition to the "Babka", which has also gained popularity among the military.

NFC cards instead of paper tickets. How the automated Kernel elevator works without scales, unnecessary movements and piles of waste paper
NFC cards instead of paper tickets. How the automated Kernel elevator works without scales, unnecessary movements and piles of waste paper
Ten years ago, the process of loading and unloading grain elevators (granary) "Kernel" by grain trucks worked according to a linear analog algorithm. The guard at the checkpoint registered the car, the driver received a registration ticket and went to the weigher, the laboratory manually recorded the quality of the grain, the driver got out of the car several times and "walked in circles", and at the exit from the elevator the guard checked whether anything "superfluous" was being taken out. Everything was accompanied by paper tickets, queues and the risk of errors. Now the process has changed dramatically: the driver does not leave the cab at all, documents are signed with an electronic signature, and the human factor in the process of cargo clearance is minimized.

What SAF-T UA changes for business and IT teams
A tax audit is traditionally associated with documents: contracts, invoices, invoices, and accountant’s explanations.

The digitalization of the justice sector has its own specific challenges: it is necessary not only to digitize a colossal array of sensitive data, but also to ensure the cybersecurity of state registries, which are at constant risk during a full-scale war.
CDTO of the Ministry of Justice Olga Ryabukha has been in office for a little over a year, but before that she already had extensive experience in digitalization of key government processes at the Ministry of Digital Affairs and a number of projects. She emphasizes that the digital transformation of the Ministry of Justice should not be a set of individual IT projects, but a systemic change in the way the justice sector works.

How Kernel made traffic flows at production facilities predictable with TransitHUB
How Kernel made traffic flows at production facilities predictable with TransitHUB
A few years ago, at night, there were queues of grain trucks under the Kernel elevators — dozens of cars at once. The drivers spent the night in the cabins, and a guard with a flashlight counted the cars and made sure that no one got ahead. A truck could stand under the gate for up to three days: the carrier did not earn money during this time, the company overpaid for downtime, which was included in the tariff by contractors, and the company did not understand when exactly the raw materials would arrive.
Today, this picture is no longer there. But, as it turned out, removing the live queue turned out to be a much more difficult task than simply «making slot reservations.» Over six years, Kernel’s internal platform for managing transport logistics — TransitHUB — has grown from a simple electronic recording tool into a highly critical production system, on which the reception and shipment of 30 elevators, 6 factories and 5 terminals depend, and it is used by about 50,000 drivers.

Cryptocurrency has become the attention economy: why the most valuable asset is not the token, but the user's attention
One of the most famous airdrops in the history of the industry ended on a high note. According to Dune analysis, over 75% of wallets that received Uniswap tokens sold them within the first week. Over time, the share of those who completely disposed of their UNI reached 93%, with only about 7% of wallets still holding any tokens. These numbers clearly show one feature of airdrops: the token received does not always create long-term loyalty. In this sense, an airdrop is not like buying attention, but rather its short-term rental. A project can pay a person to come, make a transaction, or try a product. It is much more difficult to pay for them to stay after the incentives end.
