    • Apply SOLID, Clean Architecture, and Domain-Driven Design principles; enforce them through code reviews and pair programming.
    • Drive AI-assisted development across the team including GitHub Copilot/Copilot Chat, prompt libraries, code-generation guardrails, secure prompt patterns, and test generation.
    • Integrate LLM-powered capabilities into applications (chat, summarization, classification, RAG) via Azure OpenAI/AWS Bedrock; wire PII/PCI/PHI guardrails at the prompt boundary.
    • Write and maintain unit, integration, and contract tests (xUnit.net/NUnit, Jasmine/Karma, Playwright) while targeting 80%+ coverage on core services.
    • Own CI/CD in Azure DevOps or GitHub Actions with Build -> Test -> Security Scan -> Deploy to AWS via CDK or Terraform.
    • Instrument with OpenTelemetry; publish metrics/traces to CloudWatch + Managed Grafana.
    • Partner with architects, product owners, and QA to break epics into deliverable sprint work; mentor 2-4 mid-level engineers.

    • 8+ years professional software engineering; 5+ years on C#/.NET production applications.
    • Strong ASP.NET Core Web API and Entity Framework Core skills including async/await, dependency injection, minimal APIs, and middleware pipeline.
    • Angular 15+ production experience including components, RxJS, NgRx or signals, standalone components, reactive forms, lazy-loaded modules, and unit testing.
    • Deep relational database skills including schema design, indexing, query tuning, execution plans, stored procedures, migrations.
    • Experience in SQL Server and PostgreSQL or MySQL.
    • Practical AWS Cloud experience deploying real workloads including IAM, VPC, API Gateway, Lambda or ECS/EKS, RDS/Aurora, S3, SQS/SNS, CloudWatch, Secrets Manager, KMS.
    • Demonstrable command of SOLID principles, design patterns (Repository, CQRS, Mediator, Strategy, Factory), and Clean Architecture Layering.
    • Fluency in AI-assisted development using GitHub Copilot/Copilot Chat daily as a productivity tool including writing effective prompts, evaluating suggestions critically, generating tests, refactoring, and documenting via AI; ability to coach others in the same.
    • Experience integrating with LLM APIs (Azure OpenAI, AWS Bedrock, or OpenAI) and applying safety patterns (input validation, PII redaction, output filtering, prompt-injection defenses).
    • Strong Git workflow, code review discipline, and comfort with trunk-based or GitFlow branching.
    • Excellent written and verbal communication; ability to write design docs, ADRs, and runbooks.
