Application Development & Implementation

·        Design, implement, and refactor serverside components using C# and ASP.NET MVC targeting .NET Framework 4.8.

·        Build and maintain Razor views and client behaviors using HTML5, CSS3, JavaScript, jQuery, and Bootstrap.

·        Implement business logic, background jobs, scheduled tasks (Windows services / Task Scheduler), and server-side processing without introducing API layers.

·        Use Entity Framework or ADO.NET and stored procedures for direct database access and transactional logic.

·        Participate in code reviews and enforce coding standards, security, and maintainability best practices.

Database, Integration & ETL Collaboration

·        Work with Azure SQL / SQL Server schema, stored procedures, indexing and performance tuning.

·        Collaborate with data engineers on SSIS packages, ETL processes, and file-based interfaces; validate integration points and data flows.

·        Implement data access patterns that support migration validation and referential integrity checks.

Quality, Performance & Security

·        Profile and resolve performance issues; implement caching, batching, and asynchronous processing where appropriate.

·        Apply secure coding practices; implement authentication/authorization used by the project (Windows auth, Forms auth, or Azure AD as applicable).

·        Assist with operational support: logging, monitoring, diagnostics and incident response runbooks.

DevOps & Release Management

·        Contribute to CI/CD pipeline definitions and maintenance in Azure DevOps (builds, tests, packaging, deployments).

·        Produce deployment artifacts and support automated deployments to test, staging, and production environments.

·        Maintain deployment documentation and rollback plans.

Agile/Scrum Collaboration

·        Participate in all Scrum ceremonies (daily standups, sprint planning, reviews, retrospectives).

·        Collaborate closely with QA, data migration specialists, and business SMEs to deliver sprint goals.

Technical Skills & Qualifications

Required

·        Strong professional experience with C# and .NET Framework 4.8 (ASP.NET MVC, Razor views).

·        Experience with Entity Framework and/or ADO.NET, T-SQL, stored procedures, and query performance tuning on SQL Server / Azure SQL.

·        Proficiency with front-end technologies used by the project: HTML5, CSS3, JavaScript, jQuery, Bootstrap.

·        Practical experience with Azure DevOps: Git source control, build/release pipelines, work item and test management.

·        Familiarity with Visual Studio 2022 for day-to-day development and debugging.

· Strong troubleshooting skills and experience resolving production defects and performance issues.

Preferred

·        Experience with unit and integration testing frameworks and test automation.

·        Handson experience with SSIS or similar ETL tooling and coordinating application-side integration with ETL processes.

·        Prior experience modernizing legacy .NET Framework applications in public-sector or enterprise contexts.

·        Familiarity with Windows services, scheduled tasks, or job schedulers used to run background processing.

·        Experience with application logging/telemetry and operational runbooks.

·        Knowledge of security/access controls for enterprise applications and data handling best practices.

·        Exposure to accessibility (WCAG) and cross-browser compatibility testing.

Key Deliverables

·        Implemented user stories with server and UI components.

·        Technical design documents, UI mapping, and runbooks for operational support.

·        Database schema updates, stored procedures, and performance tuning changes.

·        SSIS/ETL coordination artifacts and integration test results.

·        Unit/integration test artifacts and CI pipeline results in Azure DevOps.

·        Deployment artifacts, pipeline definitions, and rollback/runbook documentation.

·        Status reports, defect logs, and knowledge transfer materials.
