Project description and requirements for Background to the assignment

The company provides Data Science support for chemistry product development and support R&D. This includes the design and development of production-ready web application to serve the developed data science model to the end-user and other things.

Therefore, the development requires a secure setup of Azure services according to an existing system architecture. To keep compliance with company's standards, the setup needs to be automated using Terraform and should follow Microsoft recommendations for security and networking. There is also a need for a proper test environment concept and deployment automation for the web application components according to the concept.

Consequently, we need an expert with sufficient expertise in connection with Azure Serverless technologies in a secure setup and their automated deployment, handling of test environment as well as logging and monitoring of serverless applications.

Backlog items will be assigned in Azure DevOps containing business requirements and acceptance criteria.

Workload based on Agile environment, 2 weeks sprints. With Sprint meetings once in two weeks and Daily meetings.

Tasks

Automation of build and deployment of web app components based on Docker container and Azure serverless technologies

• Staged deployment and test environment concept for App Service apps and Function App APIs
• Concept for deployment and hosting of API specs
• Concept for deployment and hosting of code documentation
• Concept for logging and monitoring of serverless functions App Service apps and Function App APIs

Automation of Azure services provisioning based on Terraform

• Setup of Azure App Service, Function App under consideration of Azure security recommendations and automation via Terraform
• Setup of Cosmos DB under consideration of Azure security recommendations and automation via Terraform

Documentation of technical implementation which is subject to approval by the client.

Project

The (further) development of software for the purpose of iterative experiment design, data visualisation and connection to the Alb. database.

Backend Components:

Therefore, the software development also requires the design and development connectivity to the Alb. database via REST API as well as the frontend with user interface. The first component of API development is required to be developed using Python and TypeScript as well as serverless technologies based on Azure. Developer will be responsible for creating web application backend components from scratch, which will be exposed as REST Web APIs to frontend. In this role, you should be able to write functional code, which handles data from external REST APIs as well as from NoSQL database.

Frontend:

The second frontend component requires proficiency in AngularJS and TypeScript with the ability to make code design decisions. In addition, the developer has Python development skills, experience in API development and testing as well as in data visualization frameworks like D3.js.

Backlog items will be assigned in Azure DevOps containing business requirements and acceptance criteria.

Tasks:

-       Affiliation of scalable and responsive cloud-based Web application using state-of-the-art frontend engineering practices by:

o  Designing a technical concept, coding, testing and documentation according to the backlog item based on TypeScript and Python [BE]

o  Designing a technical concept, coding, testing and documentation according to the backlog item based on AngularJS and TypeScript [FE]

o  Translation of UI/UX design wireframes to actual code, by developing web user interface components and related tests [FE]
