Job description / Role

Description

Senior full-stack developer with 5+ years of professional experience delivering enterprise web applications using ASP.NET Core (.NET 6+) and Angular (latest versions, including Angular 17+). Specialized in clean architecture and onion architecture, applying proven design patterns and modern development practices to build scalable, maintainable, and secure systems.

Key responsibilities

Backend development (.NET Core)

• Designed and developed secure, scalable RESTful APIs using ASP.NET Core Web API and C#.
• Applied onion architecture to enforce separation of concerns across domain, application, infrastructure, and presentation layers.
• Implemented the repository pattern to abstract data access logic and promote testability and loose coupling.
• Used the mediator pattern (MediatR).
• Developed data access layers using Entity Framework Core (EF Core) with:
  • Code first approach
  • Database migrations for schema versioning and controlled evolution
  • Fluent API and data annotations for entity configuration
• Wrote optimized data queries using LINQ (method and query syntax) to:
  • Retrieve complex relational data
  • Improve query performance
  • Minimize database round-trips
• Designed and optimized SQL Server databases, including indexes, constraints, and query tuning.
• Implemented unit of work for transactional consistency across multiple repositories.
• Integrated authentication and authorization using JWT and OAuth 2.0, including role-based and policy-based access control.
• Handled cross-cutting concerns such as validation, logging, and exception handling using MediatR pipelines and middleware.

Frontend development (Angular)

• Built modern, responsive, and reusable UI components using Angular 17+, TypeScript, HTML5, and SCSS, aligned with the organization’s design system.
• Implemented Angular best practices including:
  • Modular architecture and lazy loading
  • Reactive forms and custom validators
  • RxJS observables for asynchronous data streams
• Integrated frontend applications with RESTful APIs, managing authentication tokens, error handling, and loading states.

Software design & best practices

• Followed SOLID principles, clean code, and clean architecture standards.
• Applied additional design patterns where appropriate:
  • Unit of work
  • Factory pattern
  • Strategy pattern
  • Specification pattern
  • Dependency injection
• Wrote unit and integration tests for business logic, repositories, and API endpoints.

Collaboration & delivery

• Collaborated effectively within Agile/Scrum teams, working closely with business analysts, QA engineers, and other developers.
• Participated in sprint planning, code reviews, and technical design discussions.
• Troubleshot, refactored, and enhanced existing applications to improve performance, scalability, and maintainability.
