The stack behind the systems

Proven frameworks, named versions, and architecture disciplines that hold up in production. This is what Winmill builds with, and why your prototype and your product can share the same foundation.

  • Enterprise software since 1994
  • Microsoft Cloud Solution Provider
  • CISSP and CISA certified security leadership
  • Fortune 500 clients across North America
The principle

Boring choices, deliberately

We pick technologies your team can hire for, your auditors can reason about, and your system can still run on in five years. Novelty is a cost. When something new earns its place, we adopt it with a migration path, not a rewrite.

Continuity

From prototype to production without friction

When a prototype is built on the same architecture as the future product, there’s no rewrite waiting on the other side of success. Our tools and frameworks are production-ready from the first sprint, so you validate fast and scale on the same codebase.

The stack

What we build with

Front end

React and TypeScript for web interfaces that stay maintainable as they grow, with accessibility and performance treated as requirements rather than polish.

Back end and APIs

.NET and Node.js services, Python where data work calls for it, REST APIs documented to the OpenAPI standard, and Redis for session persistence across failure.

Mobile

Native iOS and Android in Swift and Kotlin when the platform matters, React Native when one codebase serves both. We recommend based on your product, not our preference.

Azure platform

Functions, Container Apps, Service Bus, and Event Grid for application workloads; Azure SQL, Cosmos DB, and Data Lake for storage; Entra ID for identity; Azure Monitor and Application Insights for observability.

Data and AI

Microsoft Fabric for unified data estates, Azure OpenAI and Cognitive Services for AI workloads, and the pipelines that keep both fed with clean data.

Delivery tooling

Azure DevOps and GitHub for CI/CD, infrastructure as code in Bicep and Terraform, Docker for packaging, and automated testing wired into every pipeline.

Architecture practices

The rules every build follows

API-first and modular

Services designed around interfaces from the start, loosely coupled and ready to integrate with web, mobile, and third-party systems without surgery.

Infrastructure as code

Every environment defined in version-controlled code: reproducible, reviewable, and auditable. No environment exists only in someone’s memory.

Observability built in

Monitoring, logging, and alerting from the first deployment, so performance questions get answered with data instead of vibes.

Secure by design

Identity management, encryption, least privilege, and security scanning in the pipeline, reviewed by our in-house cybersecurity practice.
