Founder & Product
Andrii Matiushev
Founded Zydeno in 2026 after a decade of building software for other people's companies. Decides what we ship and, more importantly, what we don't. Believes most apps would be better with half the features.

Design Lead
Daria Kovalenko
Owns the visual language of every Zydeno app. Type nerd, motion minimalist. Five years in print and editorial design before screens — it shows in the typography. Approves no interface that just works if it could also feel right.
- Figma
- Typography
- Design systems
- Apple HIG
- Material 3
- Fluent 2
Motion & Interaction
Bohdan Lysenko
Spent six years animating motion graphics for ad agencies before switching to product. Every spring, every tap, every transition in a Zydeno app passes through his hands. Believes a 240ms easing curve is the difference between a tool and a toy.
- After Effects
- Rive
- Lottie
- Core Animation
- Compose animation
- Web Animations
iOS & macOS Lead
Maksym Lytvyn
Native iOS since iOS 5. Allergic to SwiftUI hype, ships Swift that boots in under a second on a five-year-old iPhone. Reads release notes for fun. Owns the architecture of every iOS app we put out and reviews every pull request that touches the runtime.
- Swift
- UIKit
- AppKit
- Mac Catalyst
- StoreKit 2
- Instruments
Senior iOS Engineer
Artem Tkachuk
Eight years writing Swift, two in Objective-C before that. Goes deep on Core Data migrations, background tasks, and the parts of UIKit that StackOverflow gave up on. Carries the second on-call pager for production crashes and prefers it to feature work.
- Swift
- Core Data
- CloudKit
- Background tasks
- WidgetKit
- App Intents
iOS Engineer
Iryna Sokolova
Joined after two years building enterprise iOS components at a design-tools studio. Lives in SwiftUI when it makes sense, drops to UIKit when it doesn’t. Owns most of our shared UI components library — the small, opinionated parts every app reuses so the next release feels familiar from minute one.
- SwiftUI
- UIKit
- Accessibility
- Dynamic Type
- Swift Packages
- Snapshot tests
Android & Windows
Vitalii Pavlenko
Kotlin maximalist. Cares more about cold-start time and battery draw than feature count. Treats every kilobyte like rent. Handles the Android ports and, lately, the Windows builds — for the apps that earn one.
- Kotlin
- Jetpack Compose
- Room
- Play Billing
- WebView2
- MSIX
Backend, Web & Extensions
Oleh Voronov
Everything users never see: sync, offline-first storage, the boring parts that make the app feel magic. Runs our infra solo, builds our Chrome, Edge and Firefox extensions, and prefers it that way.
- TypeScript
- Chrome Extensions (MV3)
- Edge Add-ons
- Node.js
- SQLite
- Cloudflare
Quality & Release
Sofia Bondarenko
The last person to touch every build before it ships. Owns the QA pass and the discipline of saying not yet. Maintains the regression suite that lets the team move quickly without breaking the apps already on people’s home screens.
- XCTest
- Espresso
- Playwright
- TestFlight
- Play testing tracks
- Store certification
