.Net Core / Angular Business API-UI Development

We combined best practices for API development and are able to create a REST API and UI for Any Business Domain


Main features


  • CQRS - based approach (https://docs.microsoft.com/en-us/azure/architecture/patterns/cqrs):
  • We support Single Responsibility principle: we create separate classes for every command / query allow to use ServerLess Architecture
  • Open API / Swagger: provides real and transparent documentation and allows to generate client application
  • OAuth 2 Integration (based on Identity Server)
  • Transaction support out of the box
  • Client / Server Logging
  • DevOps automation
  • Row-Level Security Level
  • Reach permissions schema
  • Server Validation rules based on Fluent Validation API
  • TDD-approach (xUnit/nUnit)
  • UI-auto testing (using Selenium), integration testing
  • CI/CD

API Layers


Domain


This will contain all entities, enums, exceptions, interfaces, types and logic specific to the domain layer.

Application


This layer contains all application logic. It is dependent on the domain layer, but has no dependencies on any other layer or project. This layer defines interfaces that are implemented by outside layers. For example, if the application needs to access a notification service, a new interface would be added to application and an implementation would be created within infrastructure.

Infrastructure


This layer contains classes for accessing external resources such as file systems, web services, smtp, and so on. These classes should be based on interfaces defined within the application layer.

Web UI Layer (Frontend)


This layer contains frontend representation of our PWA.
Our frontend level using monorepo and store patterns , so a single git repository that holds the source code for multiple applications and libraries, along with the tooling for them.

Our technical stack


C#, .Net Core (.Net 5), EF, Dapper, MS SQL (Azure SQL), CQRS/MediatR, ClickHouse, Redis, TypeScript, Angular 12, Nx, NGRX, Docker

INFRASTRUCTURE & ARCHITECTURE DEVELOPMENT FOR ADTECH COMPANY
The last decade has seen the transfer of infrastructure to clouds and the development of cloud technologies.  Clouds are perfect for both startups and a wide range of Enterprise clients. They eliminate the need to build and maintain their infrastructure and DevOps team and have ready-made PaaS & SaaS solutions. They are often able to work according to the Pay As You Go model. However, cloud technologies are characterized by:
  • - the high cost of network traffic;
  • - insufficient optimization of PaaS solutions for specific tasks; 
  • - poor comparability of capacities in the cloud and real physical servers.
Consequently, a considerable cost increase of cloud infrastructure and emergent restrictions is highly noticeable for High Load & Big-Data projects.
Our team has come a long way from using the cloud to its On-Premise platform, which combines the flexibility and low cost of On-Premise with the reliability of the cloud.
This allowed us not only to decrease technical costs exponentially but gave rise to the successful construction of High Load & Big Data projects, such as Admixer Advertising Exchange. Read More >>
