Squash Apps — CTO-led custom software & AI development
Senior .NET engineers · 5–10+ years · Dedicated full-time

Hire .NET developers in 48 hours.

Our .NET engineers build ASP.NET Core APIs and Azure-native systems, and modernise legacy .NET Framework and Classic ASP codebases without big-bang rewrites. .NET is a long-running strength: we've scaled delivery for .NET Core SaaS platforms and embedded engineers directly into client .NET teams.

Legacy modernisation

Incremental migration from .NET Framework, Classic ASP or WebForms to .NET 8 — in production, without downtime.

Blazor & hybrid frontends

Blazor for internal tools, or React frontends on .NET APIs — we work both patterns.

Frequently asked questions

Can I interview developers before hiring?

Absolutely. You interview, optionally run a paid test sprint, and only commit when you're satisfied. No pressure.

What pricing models do you offer for .NET engineers?

Monthly retainer for ongoing work, starting at $10k/month for a single senior engineer. Hourly for short engagements. Fixed-price for project-scoped work.

What tools do your .NET developers use?

Jira, GitHub, GitLab, Linear, Slack, Notion — we adapt to your stack, not the other way around.

Are developers full-time on our project?

Yes — dedicated full-time, not shared across clients.

Can we scale up or down?

Scale up with new engineers onboarded in 48h. Scale down with two weeks notice. No contractual lock-in.

Can you migrate our .NET Framework app to .NET 8?

Yes — incrementally. We've migrated a 15-year-old Classic ASP system to .NET 8 in production with zero downtime. The approach is strangler-fig, not rewrite-from-scratch.

Do your .NET engineers work with Azure DevOps?

Yes. Azure DevOps pipelines, boards and repos are standard in our .NET engagements — including our staff augmentation work for Surgical Partners, an Australian SaaS accounting platform.

C# backend with a React frontend — do you cover both?

Yes. Several of our .NET projects pair an ASP.NET Core backend with a React or Flutter frontend. One pod can own both sides.
