Frequently Asked Questions
Yes. Before any work begins, we sign a Service Agreement covering: scope of work and deliverables, timeline and milestones, NDA (confidentiality), intellectual property rights, warranty terms, and payment schedule. We work with both companies (B2B) and individual clients. The agreement protects both parties and ensures clear expectations — included in every service at no extra cost.
For N+1 EF Core fixes: 5–50x reduction in database round-trips. For async fixes: elimination of thread pool exhaustion under load. For caching: 80–99% reduction in database calls for read-heavy endpoints.
Yes. We can work from staging with production-equivalent data, or use slow query logs and profiling data you provide from production.
No. We use Dapper only for the critical hot-path queries where EF Core creates unnecessary overhead. The rest of your codebase stays on EF Core — this is a targeted optimization, not a rewrite.
Yes. EF Core compiled queries, raw SQL via FromSqlRaw, and stored procedure calls are analyzed and optimized as part of the service.
Read replica configuration (directing read queries to replicas using EF Core interceptors) is available as an add-on if you already have a replica database configured.
This service includes a 14-day warranty. If anything doesn't work as specified after delivery — we fix it at no extra cost. No questions asked.
