From an idea to software in production, and kept running after launch.
A small studio led by a product manager. We scope the job, build it, ship it and support it. On a project you pay a fixed price per milestone, see working software every week, and the code is yours.
Found us on Upwork or Fiverr? Good. We keep the contract there.
If we met on a platform, the contract, the messages and every payment stay on that platform.
On an Upwork fixed-price contract, each milestone is held by Upwork until you accept it.
This page is here so you can open the products we built before you hire us.

People receive Outlook .msg, winmail.dat and signed .p7m files they cannot open without Outlook, and do not want to upload private mail to an unknown converter.
Solution
A viewer that reads 20 file types inside the browser tab. The server has no upload endpoint at all, so a file cannot leave the device.
Result
~1,300 people opened files in October 2026, almost all of them from Bing and ChatGPT, with no paid promotion. Clicks from Bing grew 4× in five weeks.
Habit apps nag with a checkmark and lose the reminder you snoozed at 7:02.
Solution
An Android app and a Telegram Mini App on one account, with time windows, escalating reminders and server sync.
Result
Live as an Android app (a signed APK) and in Telegram, synced across both, in 21 languages.

Who you talk to
You talk to Serhii Skrynnikov, a product delivery manager who plans every project and ships it. There is no account manager in between.
The development process is built on modern AI-assisted engineering, with tests and an independent review before any change reaches you. That is why a first version takes one or two weeks and costs less than an agency quote, and why we take only one or two projects at a time.
What we do not take on: Medical systems, building our own payment processing, native iOS apps, and anything that needs other people's personal data without a real need for it.
Questions clients ask first
Who owns the code?
On a project, you do, from the final payment, and servers, domains and accounts are in your name from the start. On our build-free subscription the code stays ours while you subscribe, and you can buy it out.
What if I am not happy with a milestone?
You do not accept it, and the payment for it stays with you or with the platform. We fix it against the agreed spec first.
How do we talk?
One chat, a written update after each working day, and a live demo every week. We answer within one working day.
Do you use AI to write code?
Yes, and every change is tested and reviewed before it reaches you. That is why a first version takes one or two weeks and costs less than a traditional agency quote.
How many projects do you take at once?
One or two. You talk to the person who plans and ships your project.
Can you work through Upwork or Fiverr?
Yes. If we met on a platform, the contract, the messages and every payment stay there. Please write to us on the platform rather than through the form below.
Tell us what you need
A written answer within one working day: what we would build, which way of working fits, a price and a date. Sending this commits you to nothing. Found us on Upwork or Fiverr? Message us there instead.
