- Design clean and scalable data-access layers using Entity Framework Core, working with databases such as SQL Server and PostgreSQL.

- Implement OAuth 2.0, OpenID Connect (OIDC), API Gateway policies, authentication/authorization, and end-to-end encryption across integration services.

- Build and maintain automated CI/CD pipelines using Azure DevOps or GitHub Actions to enable reliable and repeatable deployments.

- Apply Microservices, SOA, and Event-Driven Architecture principles to build scalable, maintainable, and resilient integration solutions.

- Troubleshoot integration issues, optimize API and service performance, and ensure solutions meet production standards for reliability, security, and scalability.
