Mobile apps and systems that hold up at scale.
We design, build and maintain digital products – from the first release to platforms with over 2 million monthly active users. Flutter, Kotlin Multiplatform, Firebase and Google Cloud. Code you can keep evolving for years.
- 2M+monthly active users across the products we build
- End-to-endmobile, backend, web and admin panel in one team
- Flutter · KMPone codebase, a native experience on iOS and Android
- Firebase · GCPinfrastructure that grows with your product
From the app in your pocket to the infrastructure behind it.
We deliver complete products. One team owns the mobile app, backend, admin panel and deployment – no handoffs, no finger-pointing.
-
Mobile apps
Flutter and Kotlin Multiplatform: one codebase, a native experience on iOS and Android. From MVP to apps with millions of users.
-
Complete systems
Backend, web app and admin panel designed together with the mobile app. One architecture, one team accountable.
-
System integrations
We connect new products with what already runs your business: ERP, CRM, payments, legacy systems. Stable APIs and clear contracts.
-
AI automation
Language models and agents plugged into real processes: document workflows, support tickets, back-office. Measurable impact, not a demo.
-
Cloud: Firebase & GCP
Architecture that scales with your product. Security, cost and observability designed from day one, not after the first outage.
-
Maintenance & growth
Monitoring, updates, refactoring and new features. We also take over existing projects and clean them up without stopping the business.
Scale proven in production, not in a slide deck.
- From the first release to a product used by more than 2 million people every month.
- Architecture designed for growth: load testing, monitoring, alerting, CI/CD.
- The same team takes the product from concept through launch to maintenance.
Quality isn’t an add-on to the quote. It’s the cheapest way to run a system.
Most of the cost of software comes after launch. That’s why we write code that’s easy to read, test and change safely – because a year from now someone will have to. Sometimes us, sometimes your team.
-
Code review for every change
No line reaches production without a second pair of eyes. -
Automated tests
Unit, integration and UI tests – run in CI on every change. -
Monitoring from day one
Crashes, logs, metrics and alerts work before the first user shows up. -
Documentation & knowledge transfer
Architecture, code and processes documented so they can be handed over.
A predictable process. No surprises at the end.
-
01
Discovery
Workshop, scope, risks and estimate. You leave with a plan, not a forty-page proposal.
-
02
Architecture & design
Technical decisions and mockups before the first line of code. This is where changing your mind is cheapest.
-
03
Iterative development
A working build after every sprint, with demos and priorities agreed together. You see progress, not reports.
-
04
Launch & maintenance
App store release, monitoring and ongoing development with the same team that knows the product inside out.
