How do you design event-driven middleware for trip chaining and flight booking systems requiring P1 reliability?

For flight booking middleware, any modification to an aircraft, base, or schedule can cascade downstream. I build modular .NET Core Web APIs integrated with Azure Functions and Cosmos DB. When an operations agent creates or modifies a flight segment, an event is emitted to re-evaluate the aircraft's entire timeline—linking previous arrivals with subsequent departures and validating crew and maintenance constraints. For P1 production stability, I implement dead-letter handling, idempotent retries, Serilog telemetry, and structured health probes to guarantee zero lost bookings or orphaned flight legs.

How do you optimize Azure SQL Database performance and throughput in high-transaction .NET applications?

I optimize Azure SQL by analyzing query execution plans via Query Store and Extended Events, eliminating full table scans through properly designed non-clustered and covering indexes on high-cardinality foreign keys. Within .NET Core, I utilize Entity Framework Core with AsNoTracking() for read queries, batch database operations, implement compiled queries, and leverage connection pooling. For reporting and intensive analytics, I isolate workloads using read-only replicas or materialized SQL Views.

Q: How do you implement Retrieval-Augmented Generation (RAG) on top of enterprise .NET and Azure SQL data?

To keep AI responses strictly grounded in operational data, I expose clean SQL Views and integrate them with Azure AI Search indexers with scheduled change-tracking. Data fields and document chunks are converted into dense vector embeddings using Azure OpenAI text-embedding models. When a user submits a query, we perform hybrid search (dense vector retrieval combined with BM25 keyword matching and semantic reranking), extract the top context chunks, and feed them into Azure OpenAI with strict system prompts that constrain the model to answer only using the retrieved context.

Technical Assessment

Screening Questions & Architecture Insights

Review Meet's verified answers to common senior cloud architecture screening questions before you interview.

I design .NET MAUI applications using the MVVM pattern with CommunityToolkit, backed by SQLite or VistaDB for on-device persistence. To handle synchronization reliably, I implement an event-driven outbox pattern: every local mutation creates an immutable change event stored in a local queue with incremental bookmarks. When network connectivity is established, a background synchronization worker transmits the payload codec to the cloud API, applies deterministic server-side conflict resolution, and receives downstream changes to update local views.
