Technologies We Consult On

Keyhole Software delivers senior-level technology consulting and custom software development across modern, cloud-native, and enterprise platforms. Our U.S.-based consultants partner directly with your team to design, modernize, and build scalable systems that solve real business problems—not just technical ones.

Our senior consultants bring deep, hands-on expertise across:

Java Development Consulting

Spring Boot, Jakarta EE, microservices, enterprise APIs, and performance optimization for mission-critical systems.

.NET Development Consulting

ASP.NET Core, Blazor, Entity Framework, Azure integration, and modernizing legacy .NET applications.

Python Development Consulting

Data platforms, AI/ML pipelines, FastAPI, Django, and integrating Python capabilities into Java/.NET ecosystems.

Modern Frontend Development

React, Angular, TypeScript, Next.js, and component libraries for enterprise-scale user experiences.

Cloud & Platform Engineering

AWS, Azure, GCP, Kubernetes, CI/CD, and designing cloud-native architectures from legacy modernization.

API & Integration Consulting

REST, GraphQL, gRPC, event-driven systems, and enterprise integration patterns.
Because our consultants actively build with these technologies, our guidance is grounded in real-world delivery — not theory. We provide strategic direction, hands-on implementation, and knowledge transfer to ensure long-term success.
