FAQ

The team works across the full .NET spectrum — .NET Core 6, 7 and 8, ASP.NET Core, Entity Framework and Dapper for modern builds, as well as legacy .NET Framework 4.x for codebase takeovers. If you're running something older and need it modernised or extended, that's a solved problem for us.

Yes. The team has taken over large-scale .NET codebases — including a 54-project solution migrated between SDK versions and from Azure Cloud Services to Service Fabric. Messy legacy code, missing documentation and technical debt are not blockers. We will read the code, map the architecture and start contributing within the first week.

Yes — Azure and AWS are part of how the team ships, not an afterthought. Azure Functions, Service Bus, Data Lake, App Services, Docker and Kubernetes are in regular use. The team has run migrations from on-premises to cloud, designed event-driven microservices, and built CI/CD pipelines from scratch.

PostgreSQL, MS SQL Server, Redis, MongoDB, Couchbase, Oracle and Elasticsearch — all in production. For ETL and data engineering, the team uses dbt and Apache Airflow for pipeline orchestration. Mixed relational and NoSQL stacks with complex ETL requirements are a regular pattern for this team.

Yes. The team has designed microservices platforms from scratch and migrated monoliths — including a global payment platform serving 100+ banks and a multi-continent fintech system with a 22-person delivery team. Architecture patterns include event-driven design, CQRS, API gateway, message queues and service mesh.

Agencies give you a named developer in the proposal and a different one on the project — often junior-heavy, managed by an account lead you only hear from on billing day. With DMexec you engage directly with the developer doing the work, and Dimmy is involved as technical sponsor on every engagement. No account manager layer, no junior fill, no markup on markup. Senior-level output at 40–60% of typical agency rates.

Fixed monthly rate per developer — no agency markup, no recruiter fees, no hidden costs. Senior .NET developers and architects are typically priced at a significant discount to equivalent Western-European or US agency rates. Book a 15-minute call and we will give you a straight number within the first conversation.

Yes — all developers work remotely. The team is European-based, which gives meaningful US and AU timezone overlap alongside full European coverage. Daily standups, async-first communication, and direct Slack access mean there is no coordination lag.

Yes — .NET staff augmentation is the primary model. You embed one or more senior .NET developers directly into your existing team: your Jira board, your standups, your Git workflow. There is no agency layer and no separate management overhead. Developers integrate as if they were hired directly — but without the recruiter fees, onboarding delays, or employer-of-record complexity. Engagements typically run on a fixed monthly rate per developer, and most teams see first production output within the first week.
