Web services, marketplaces, and desktop apps for problems a template can’t solve
From SSR catalogs and SaaS dashboards to messengers with video calls and plugin-based desktop software. Clean architecture, tests, and SEO are part of every project, not an extra.
Task: Build a full messenger: private and group chats, attachments, presence, audio/video calls, and moderation — deployed in the cloud.
Solution: .NET 10 with Clean Architecture and CQRS, SignalR for messages and call signaling, WebRTC for calls, an outbox for reliable delivery; Angular 21 client; Azure infrastructure.
Task: Port a link-building marketplace from Laravel + Vue to .NET + Angular, keeping all users and balances, and add the modules the original lacked.
Solution: Clean Architecture + CQRS with a separate Identity bounded context, an internal wallet, moderation, order chat, and SignalR notifications; physical data migration with verification.
Task: Build a cross-platform music application in the spirit of FL Studio: instrument plugins, a shared synth engine, a timeline with mixing and export, and group work over the network.
Solution: An Avalonia shell that knows only plugin contracts, six instrument plugins built on MVP, its own synthesis core, MIDI and low-latency audio backends, and a collaborative session protocol.
Task: Build an SEO-friendly wholesale storefront: catalog with filters, cart, checkout with regional delivery and payment options, reviews, and a full admin panel.
Solution: Angular 21 with SSR and a .NET CQRS backend; OpenIddict authorization server (Authorization Code + PKCE); atomic stock reservation; notifications through a background queue.
Task: Build a service that runs browser scenarios at scale: many accounts, proxies, schedules, monitoring, and live logs for the operator.
Solution: Playwright workers driven by Hangfire queues on Redis, an OpenIddict identity server, SignalR for live task status, and an Angular control panel.
Task: Replace an advertising agency's WordPress site with a custom store: products with prices go to the cart and checkout, services priced on request become lead forms, and every order and lead reaches 1C.
Solution: A pnpm monorepo with Next.js 16 (App Router) and a NestJS 11 REST API on PostgreSQL and Prisma; orders and leads reach 1C and email through a transactional outbox; Docker Compose and Nginx on a single cloud VM with nightly backups.

Migration
Architecture in detail
A stack chosen for reliability, speed, and SEO
Every part of the stack solves a specific business problem, not just a technical one.
Business logic split into clear layers — easy to test, extend, and hand over to another team.
Real-time & background jobs
SignalR WebRTC Redis Hangfire
Instant messages, live statuses, and calls; heavy work runs in queues without slowing the site down.
Desktop
Avalonia WPF / WinForms .NET MAUI Electron / Tauri
One codebase for Windows, macOS, and Linux — or a native Windows app when deep OS integration matters.
Data & cache
PostgreSQL SQLite Redis Entity Framework Core
Reliable storage, versioned migrations, and fast responses even under heavy traffic.
DevOps & cloud
Docker GitHub Actions Azure AWS Caddy
Every push deploys itself: containers, CI/CD, HTTPS, and backups set up from day one.
A transparent way of working
Every stage ends with a concrete, checkable result.
1
Discovery & scope
We break down the business problem and pin down requirements and boundaries.
2
Prototyping
We put together the structure and interface, and align on them before development starts.
3
Development
Backend and frontend move in parallel, in short iterations with demos.
4
SEO setup & testing
We configure indexing and structured data, and verify performance.
5
Launch & support
We ship the project, hand over the source code, and stay reachable.
Frequently asked questions
Short answers to what clients usually ask before we start.
How much does it cost to build a web service?
It depends on the scope: the number of user roles, integrations, and screens. We give a free estimate after a short call — with a list of features, a timeline, and a fixed price per stage.
How long does development take?
An MVP usually takes 3–6 weeks. Larger systems — marketplaces, messengers, desktop software — are built in iterations with a working demo every one or two weeks.
Who owns the source code?
You do. We hand over the repository, deployment access, and documentation, so your own team or another contractor can continue the project without a rewrite.
Can you take over or migrate an existing project?
Yes. We start with a code audit, then refactor or port the project — for example from PHP/Laravel to .NET and Angular — preserving all users and data.
Will the site be visible in Google and Yandex?
Public pages are rendered on the server, have their own URLs in every language, a sitemap, and structured data. We also set up Google Search Console and Yandex Webmaster.
Do you build desktop apps for macOS and Linux?
Yes. With Avalonia, Electron, or Tauri one codebase runs on Windows, macOS, and Linux. When deep Windows integration matters we build a native WPF or WinForms app.
What happens after launch?
We stay in touch: we fix bugs, monitor errors (alerts come to Telegram), update dependencies, and develop new features on request.
