WHAT WE BUILD

CUSTOM SOFTWARE DEVELOPMENT

CUSTOM WEB APPLICATIONS

Blazor and ASP.NET Core apps, APIs, and SQL Server back ends built around your workflow, with Azure DevOps for build and deploy.

INTEGRATIONS & DATA

Connect the systems you already use and turn your operational data into Power BI dashboards and reporting.

HOSTING & DEVOPS

Linux and Windows servers, Azure, and CI/CD with Azure DevOps. We deploy and run what we build, so your app stays fast, patched, and backed up.

LINUX ARCHITECTURE

RHEL and Rocky Linux server design and builds, Docker and Kubernetes container platforms, virtualization and GPU passthrough, hardening, monitoring, and automation.

PRODUCT-GRADE DELIVERY

The same team and stack that ships MyFFLBook and Logistor, applied to your project: tested releases, documentation, and support after launch.

HOW WE WORK

Discover your workflow and goals → Build in short, reviewed iterations → Launch on hosting we manage → Support and improve it over time.
