Job description

Project

This project is for a foreign client, focused on rebuilding two internal enterprise applications (SLFS and MLFS). The current solutions are based on deprecated AngularJS and a tightly coupled .NET Framework 4.7 backend. The goal is to migrate to a modern, maintainable architecture using Angular v20 and a decoupled REST API layer.

The new frontend will be developed as standalone Angular SPAs using Angular Material, CDK, RxJS, and Signals. It will be structured into feature modules with strong emphasis on scalability, code quality, and accessibility. Frontend and backend will be deployed independently via separate CI/CD pipelines, enabling safe, incremental rollout.

On the backend side, a new ASP.NET Web API layer will be introduced to expose existing business logic and data. The API will be documented via Swagger and secured using token-based authentication (e.g., JWT). Legacy systems and infrastructure (Azure VMs, IIS, SQL Jobs) will remain in place, ensuring a smooth transition without disrupting existing operations.

Contract duration: 2 months - possible extension

You can be the perfect match for us, if you have:

Strong Knowledge of .NET Framework 4.7, including:

• Development and maintenance of ASP.NET MVC applications

• Experience working with controllers, views (.cshtml), and ViewBag / ViewData mechanisms

• Proficiency in ASP.NET Web API – designing and implementing RESTful APIs (based on .NET Framework 4.7 or .NET Standard)

• Knowledge of Entity Framework (Code First) – domain modeling, migrations, LINQ queries, and database integration

• Experience with authentication and authorization systems, particularly those based on EUA, cookies, and JWT (JSON Web Tokens)

• Familiarity with API documentation tools and standards – Swagger / OpenAPI

• Experience with IIS – deploying and configuring applications hosted on Windows Server

• Knowledge of SQL Server and integration with batch jobs (SQL Jobs) – a plus

Architecture and Modernization Skills:

• Ability to decompose monoliths – extracting business logic from controllers and .cshtml views into separate service/API layers

• Understanding of layered architecture and frontend/backend separation

• Capability to design versioned APIs tailored for integration with SPA frontends (e.g., Angular)

DevOps and Deployment Experience:

• Experience working in projects with CI/CD pipelines, integrating deployments with existing infrastructure (e.g., Azure VMs, IIS)

• Knowledge of API publishing, versioning, and preparation of deployment packages

• Familiarity with configuration management tools and change control systems (e.g., Git, Azure DevOps)

What do we offer?

• ambitious, creative, talented & highly experienced team

• contributing to projects for clients all over the world

• flexible working hours and a possibility to work remotely
