Hi S***e, Great questions,here’s a quick rundown: 1. Reporting Structure You’ll report directly to our Engineering Manager, who oversees all .NET initiatives and partners closely with Product and QA. She’s a hands-on leader with deep ASP.NET Core expertise and will work with you on roadmap planning, architecture reviews and career growth. 2. Code Reviews We use GitHub (Azure DevOps) pull requests with a standardized checklist based on Microsoft C# style conventions, SOLID/Clean Architecture principles and our own clean-code guidelines. Every PR triggers our CI pipeline (including SonarQube static analysis) and is reviewed by at least two peers. We also hold weekly “review roundup” sessions to share learnings and refine our process. 3. Architecture Our platform is a microservices-based ecosystem built on ASP.NET Core. Each domain (billing, user management, reporting, etc.) lives in its own container and communicates via REST/gRPC. We deploy services to Kubernetes, which gives us independent scaling, streamlined CI/CD and clear boundaries for teams to own. 4. Biggest Near-Term Challenge Over the next few months, you’ll help migrate our legacy reporting module into a standalone microservice, optimize SQL schemas for multi-million-row datasets and establish cross-service performance standards. Your background in database tuning and clean, maintainable code will be crucial as we roll out this new service and gear up for our next major feature release. Let me know if you’d like any deeper dive on tooling or architecture before our call on Wednesday. Looking forward to chatting! Best, J***e HR Recruiter, StrategyBrain

Hi S***e, Sure,here’s a deeper look: 1. CI/CD Process - We use Azure DevOps pipelines for build, test and deploy. - Unit and integration tests must achieve ≥80% coverage before a PR can merge. - SonarQube Quality Gate is configured to block on any new blocker/security issues and enforces a minimum reliability rating. - On a failed deployment (smoke tests or health probes), the pipeline triggers an automated Helm rollback in Kubernetes. We also maintain a manual rollback option in Azure DevOps for quick intervention. 2. Monitoring & Alerting - Application Insights captures distributed traces, exceptions and request performance for each .NET Core service. - Prometheus scrapes service and container metrics; Grafana dashboards visualize CPU, memory, error rates and custom business KPIs. - Alert rules in Azure Monitor (and Prometheus Alertmanager) notify the on-call via Teams and PagerDuty when thresholds (e.g. >5% error rate, latency spikes) are breached. 3. Reporting Module Migration - We’re running a two-phase approach: a) Bulk export/import via offline SQL scripts during a scheduled maintenance window to seed the new reporting database. b) Incremental sync using SQL Server Change Data Capture and a lightweight sync service to keep data in sync until cut-over. - This hybrid method lets us validate correctness on the new microservice while minimizing downtime. Hope this gives you a clear picture,happy to share pipeline snippets or architecture diagrams ahead of our call. Let me know what else you’d like to unpack! Best, J***e HR Recruiter, StrategyBrain

Hi S***e, Below is a trimmed-down snippet of our Azure DevOps YAML that illustrates how we enforce ≥80% coverage and SonarQube gates. After that, I’ve outlined how our incremental sync service handles schema evolution and conflict resolution during cut-over. 1) Azure DevOps Pipeline YAML (excerpt) ```yaml trigger: branches: include: [ master, develop ] pool: vmImage: 'windows-latest' variables: buildConfiguration: 'Release' coverageThreshold: 80 stages: - stage: BuildAndAnalyze jobs: - job: Build_Test_Sonar steps: - task: UseDotNet@2 inputs: packageType: 'sdk' version: '7.x' - task: DotNetCoreCLI@2 name: RunTests inputs: command: 'test' projects: '**/*Tests/*.csproj' arguments: '--configuration $(buildConfiguration) --collect:"XPlat Code Coverage"' - task: PublishCodeCoverageResults@1 inputs: codeCoverageTool: 'Cobertura' summaryFileLocation: '$(Agent.TempDirectory)/**/coverage.cobertura.xml' # Inline PowerShell to enforce coverage threshold - powershell: | $report = Import-CoberturaReport -Path "$(Agent.TempDirectory)/**/coverage.cobertura.xml" if ($report.LineCoverage -lt $(coverageThreshold)) { Write-Error "Code coverage $($report.LineCoverage)% is below threshold $(coverageThreshold)%." } displayName: 'Check Coverage ≥ 80%' - task: SonarQubePrepare@5 inputs: SonarQube: 'SonarQubeServiceConnection' scannerMode: 'MSBuild' projectKey: 'InnovaTech.Microservices' - task: SonarQubeAnalyze@5 - task: SonarQubePublish@5 inputs: pollingTimeoutSec: 300 ``` Key points: - We collect coverage in Cobertura XML, then run a small PowerShell snippet to enforce the 80% gate. - SonarQubeQualityGate blocks the pipeline if there are new blockers/security issues or reliability rating drops. 2) Reporting Migration , Incremental Sync, Schema Evolution & Conflict Resolution We run a two-phase migration: a) Bulk Load • Offline SQL scripts dump and import the full dataset during a maintenance window. • We apply schema migration scripts (via our versioned Flyway/EF migrations) on both old and new databases before the load, ensuring table structures align. b) Incremental Sync Service • CDC on the source captures inserts, updates, deletes. • Our sync service reads CDC streams, applies the same versioned migration scripts on-the-fly if it encounters a new column (it checks a migration-version table first). • For conflict resolution at cut-over: , We treat the legacy DB as source of truth until the final switchover. , If the CDC record’s timestamp is older than a conflicting change already applied to the target, we skip it. , If both systems have divergent updates (rare), we raise a low-impact alert and apply a “last modified wins” rule based on UTC timestamps. This hybrid approach lets us: - Validate the new schema and data ahead of switch-over. - Keep data in sync with minimal downtime. - Handle schema drift by versioned migrations and an adaptive sync service. Let me know if you’d like the full YAML or a deeper dive on any piece before our call. Looking forward to it! Best, J***e HR Recruiter, StrategyBrain

Hi S***e, Great questions,here’s how we handle both of those edge cases: 1) Versioning & Smoke-Testing EF Migrations - Every migration is scripted in C# and checked into Git alongside feature branches, so we get full history and semantic versioning. - In our CI pipeline, before merging, we spin up a throwaway SQL container, apply all pending EF migrations, then run a suite of integration tests (including schema-driven tests for zero-data, existing-data and conflict scenarios). - We also include a small “rollback” test: after applying the migration, we automatically roll back to the previous snapshot to ensure our Down() scripts hold up. Any failures block the PR. 2) Auditing Skipped CDC Events - When the sync service drops older CDC entries (timestamp < target’s last-applied LSN), it logs those event IDs and row keys in an audit table. - We run a nightly reconciliation job that compares source vs. target row counts and checksums (per table/partition) for any gaps. - If discrepancies surface, the job surfaces a report and can rehydrate only the missing buckets via a targeted re-sync. We also maintain a “gap alert” in Grafana so the on-call engineer sees it immediately. Let me know if you’d like sample scripts or a deeper dive in our call,I’m happy to loop in one of our senior back-end engineers for the nitty-gritty. Looking forward to Wednesday! Best, J***e

Hi S***e, Below is an excerpt from our integration-branch pipeline YAML showing how we generate and smoke-test an idempotent EF migration script, followed by a partition-management job that adds new partitions dynamically. ```yaml trigger: branches: include: - integration pool: vmImage: 'windows-latest' variables: buildConfiguration: 'Release' stages: - stage: GenerateAndSmoke jobs: - job: MigrateAndSmoke steps: - script: | dotnet tool install --global dotnet-ef dotnet ef migrations script --idempotent -o idempotent.sql displayName: 'Generate idempotent EF migration script' - script: | sqlcmd -S $(DbServer) -d $(DbName) -i idempotent.sql displayName: 'Apply migrations to scratch DB' - script: | dotnet test --configuration $(buildConfiguration) --filter Category=Smoke displayName: 'Run smoke tests' - stage: PartitionManagement jobs: - job: AddNewPartitions steps: - task: AzureCLI@2 name: SplitPartition inputs: azureSubscription: 'YourServiceConnection' scriptType: 'ps' inlineScript: | # 1) Read last boundary from meta table $lastBoundary = (Invoke-Sqlcmd -ServerInstance $(DbServer) -Database $(DbName) ` -Query "SELECT MAX(PartitionBoundary) FROM dbo.PartitionMeta").Column1 # 2) Calculate next boundary (e.g. add 1 day/month) $nextBoundary = (Get-Date $lastBoundary).AddDays(7).ToString('yyyy-MM-dd') # 3) Split the partition function $splitCmd = "ALTER PARTITION FUNCTION PF_MyTableRange() SPLIT RANGE ('$nextBoundary')" Invoke-Sqlcmd -ServerInstance $(DbServer) -Database $(DbName) -Query $splitCmd # 4) Persist new boundary $insertCmd = "INSERT INTO dbo.PartitionMeta (PartitionBoundary) VALUES ('$nextBoundary')" Invoke-Sqlcmd -ServerInstance $(DbServer) -Database $(DbName) -Query $insertCmd displayName: 'Add next partition based on current data growth' ``` Key points: - We target the **integration** branch, generate an idempotent EF script, apply it against a throwaway DB, then smoke-test. - For partition growth, we keep a **PartitionMeta** table tracking the last split boundary. A lightweight PowerShell step: 1. Reads the most recent boundary 2. Calculates the next range (e.g. +7 days or monthly) 3. Issues an `ALTER PARTITION FUNCTION … SPLIT RANGE` 4. Logs the new boundary for future runs Let me know if you’d like the full pipeline or any extra details before our Wednesday 14:00 IST call. Looking forward to diving deeper!
