Devlyn AI · .NET · London
.NET engineering for London teams.
Bypass the London talent shortage. Deploy a senior .NET pod aligned to your time zone in 24 hours.
The intersection
Building .NET teams in London is structurally constrained by local supply. London FTE hiring runs 3–5 months for senior fintech and AI roles, with offers regularly contested by US tech giants opening UK offices. Pod retainers compress the calendar and arrive without sponsorship/visa overhead.
AI-augmented .NET workflows lean on Cursor and Claude Code for controller and minimal-API endpoint scaffolding with proper model validation, EF Core entity configuration with Fluent API relationship mapping, migration authoring with proper data-seed handling, MediatR handler patterns for commands and queries with pipeline behaviours, and integration-test generation using WebApplicationFactory — all under senior validation that owns architecture decisions, EF Core query performance tuning (query plan analysis, N+1 detection, compiled queries), security review on ASP.NET Core Identity and authorization policy configuration, and .NET-specific patterns like dependency-injection lifetime management, middleware ordering, and background-service lifecycle management with IHostedService. Compression shows up strongest in endpoint scaffolding, EF Core configuration, and test infrastructure.
.NET engagements at Devlyn typically run as one senior backend engineer plus shared DevOps for $5,000–$9,000/month, covering service architecture, EF Core entity design, and Azure deployment pipeline. This scales to a two- or three-engineer pod when the roadmap splits into parallel lanes across enterprise-integration work (connecting legacy .NET Framework systems), Blazor frontend development, and Azure-platform infrastructure including Functions, Service Bus, and Cosmos DB management. Pods share a single retainer with flexible allocation.
