From idea to launch, from launch to growth
Web applications
Admin panels, customer portals, B2B platforms and SaaS products. Multi-tenant, role-based and scalable.
Mobile apps
iOS and Android from one Flutter codebase; push notifications, offline mode, payments and maps.
APIs & integrations
ERP, accounting, CRM, e-commerce, shipping, payment and WhatsApp Business integrations; secure REST APIs and webhooks.
AI solutions
LLM-powered customer assistants, document and call summarization, auto-classification and smart workflows.
Communication software
VoIP/SIP, WebRTC, softphones, contact center and real-time apps — the field where we built our own PBX.
Modernization & recovery
Migrating legacy systems to modern stacks, recovering apps with lost source code, performance and security hardening.

Launch & care
Go-live, store release, monitoring and continuous improvement.
A proven, long-lived technology stack
Software development — frequently asked questions
Which technologies do you use?
On the web and server side we use .NET / ASP.NET Core and SQL Server; on mobile, Flutter for iOS and Android from a single codebase. For real-time communication we use SignalR, WebRTC and SIP, and REST APIs and webhooks for integrations.
How long does a software project take?
It depends on scope. We first clarify requirements in a discovery session and produce a plan and schedule broken into work items. We work in two-week sprints and demo a working version at the end of each.
Do you publish apps to the App Store and Google Play?
Yes. We handle the entire release — account setup, signing, store listings, the review process and updates.
Who owns the source code?
For custom software, source code and IP rights are clearly defined in the contract; our standard approach is to hand over the code to the customer at the end of the project.
Can you integrate with our existing systems?
Yes. We have integration experience with ERP, accounting, CRM, e-commerce, payment, shipping, WhatsApp Business and ad platforms (Meta, Google, TikTok, LinkedIn).
Do you provide maintenance after launch?
Yes. We offer monthly maintenance agreements covering hosting, monitoring, security updates, bug fixes and new development.
