Custom Software Development

Senior engineering for serious software.

Not every project needs AI. Some need a well-architected backend, a clean API, a reliable deployment pipeline, or a legacy system that finally works properly. That's what we've been doing for 25 years.

What we build

• SaaS MVPs — get from idea to working product fast, with architecture that won't need a rewrite when you scale
• REST API platforms — clean, documented, testable APIs that your frontend, mobile app, or partners can integrate with
• Backend systems — data processing, business logic, integrations, and everything that happens behind the UI
• Legacy modernization — refactor monoliths into microservices, upgrade .NET Framework to .NET 8+, or restructure a codebase that's become unmaintainable
• Plugin and integration development — build plugins for existing platforms (AutoCAD, desktop apps, third-party systems)
• DevOps and CI/CD — Azure Pipelines, GitHub Actions, Docker, automated testing, and deployment infrastructure

Our stack

• Backend: .NET / C# / ASP.NET Core (25+ years production experience)
• Frontend: Blazor, Razor Pages, WPF, WinUI3
• Database: SQL Server, PostgreSQL, CosmosDB, SQLite
• Cloud: Azure (Storage, Functions, Service Bus, Pipelines, AD)
• Architecture: Clean Architecture, Domain-Driven Design, SOLID, TDD
• DevOps: Docker, Azure Pipelines, GitHub Actions, YAML

Track record

We've built production software for:

• Fugro — geotechnical data platform with AutoCAD Civil3D integration (30+ year product)
• Shell — 3D subsurface modeling app refactored to WebAPI
• Rabobank — client rating engine with DSL modeling and claim-based security
• Deltares — research software for water and soil management
• SITA — airport equipment control systems

These aren't portfolio projects — they're production systems serving real users in demanding environments.

How we work

1. Discovery — understand your problem, constraints, and what success looks like
2. Architecture — design the system with Clean Architecture principles before writing code
3. Build — incremental delivery with tests at every layer, regular check-ins
4. Deploy — CI/CD pipeline, documentation, and a clean handoff

You get clean, tested, documented code that your team (or your next developer) can maintain and extend.

Pricing

Custom software projects are scoped individually. Typical engagements:

We work on fixed-price or time-and-materials depending on the project. Always scoped and agreed before we start.
