Build with us
like you'd build in-house.

Hire ASP.NET developers who join your team, your Azure DevOps board, and your standups — backed by an 85-engineer .NET organization that ships ASP.NET Core APIs, Blazor apps, SignalR realtime, and Azure-native systems for enterprises.

On your team, day 1

Engineers join your Microsoft Teams, your Azure DevOps, your sprint board. They pair with your .NET team like senior in-house hires.

Direct git access

They open PRs straight into your Azure DevOps or GitHub. You see every controller, every EF migration, every xUnit test.

You manage the work

You set architecture and roadmap. We handle hiring, payroll, certifications (AZ-204, AZ-400), and equipment.

to onboarded — in 2 weeks.

4-step process. 48 hours to first profile. 2 weeks to a .NET developer joining your standup.

01

We map your .NET version, hosting (Azure, on-prem, IIS), persistence (SQL Server, Cosmos), and integration points (Service Bus, AD).

02
Day 3-5

Choose a Resource

3-5 .NET developer profiles in 48 hours, matched to your Azure stack and domain.

03
Day 6-10

Start an Interview

Interview the shortlist. We support with a live ASP.NET Core coding round, EF Core query design, and reference checks.

04
Day 11-14

Onboarding

MSA, NDA, Azure DevOps access, key vault credentials. By day 14, first PR through the pipeline.

Why Choose WebSenor

10 reasons enterprises pick us
over for .NET over alternatives.

01

5-step vetting

02

100% source code authorization

You get complete ownership of clean C# source code, .editorconfig included. MSA assigns IP on day 1.

03

Enterprise + Azure DNA

Our .NET engineers have shipped systems for insurance, healthcare, ERP, and government — Active Directory, SAML, audit logs included.

04

Modern .NET 8 / 9

Minimal APIs, source generators, native AOT, Blazor United — our bench ships current .NET, not Framework 4.x patterns repackaged.

05

Excellent communication

Clear written ADRs, well-described PRs, async-first collaboration.

Client Voices

What companies say
about hiring from us.

"
★★★★★

Their ASP.NET Core lead migrated our 600k-LOC Framework monolith to .NET 8 without a single rollback. Azure costs dropped 38%.

VE
VP Engineering, US insurance carrier
"
★★★★★

Blazor SignalR at 80k concurrent users is not a beginner project. The engineer they sent had done it before — and the architecture held.

DP
Director of Platform, logistics SaaS
"
★★★★★

Azure Functions + Service Bus done right is rare. Their event-pipeline engineer built exactly-once semantics into our order system end-to-end.

Frequently Asked Questions

Everything you need
to know before hiring.

.NET Framework, .NET Core, or .NET 8 — which do your devs cover?
All three. Most new builds default to .NET 8 (LTS) or .NET 9. We have a smaller bench maintaining .NET Framework 4.x and .NET Core 3.1 legacy systems, and engineers who lead modernization migrations end-to-end.
Blazor Server, WASM, or United?
All three. Blazor Server for internal LOB / admin apps with low-latency back-end. WASM for offline-capable / customer-facing apps. Blazor United (.NET 8+) for unified server-render + interactive islands. We match the dev to your pattern.
Can your .NET engineers handle Azure end-to-end?
Yes. App Service, AKS, Functions, Service Bus, API Management, Key Vault, Cosmos DB, Application Insights, Bicep IaC. About 70% of the bench holds AZ-204 or AZ-400 certifications.
What about SignalR at scale?
Yes. We've shipped SignalR backplanes with Redis + Azure SignalR Service handling 80k+ concurrent connections with reconnection resilience.
EF Core or Dapper?
Both. EF Core is the default for transactional code with complex graphs. Dapper for read-heavy or performance-critical paths. We routinely mix both in a single service.
What does the 14-day SLA cover?
Day 1 discovery to day 14 first PR. Shortlist day 3-5, interviews day 6-10, MSA + Azure DevOps access day 11-13.
What about IP, NDAs, source code?
100% source code authorization standard. MSA assigns IP to you on day 1.
Do you work in our timezone?
Yes. India team gives 4-6 hours of EU / US East overlap.
