Conferencing and interpreter search platform for medical domain

The system used in hospitals to search interpreters for foreign patients. Communication can be both via video communication and audio. In addition, there are additional services for analytics and monitoring, a portal for system configuration, a portal for interpreters. Backend part developed using .NET stack, frontend part developed using Angular and React.

Personal results:
• Designed and developed database structure for MongoDb
• Designed and developed core call flow logic
• Designed and developed application API (for HTTP and SignalR)
• Implemented authentication and authorization flow (IdentityServer4)
• Implemented backend components integration using Orleans
• Introduced unit and acceptance testing
• Gained great experience and skills from creating a project from scratch

Development Environments: C#, JavaScript, ASP.NET MVC, Visual Studio, Orleans, Azure Devops, Azure Storage, MongoDb, Docker

Banking mobile and web application backend

Backend platform for mobile and web applications, processing up to 100 requests per second (with estimate limit 10К+ RPS). Platform is a set of microservices, interacting with bank financial services and logic. System provides full banking services, like transfer money, open/close deposit and card products, loans etc. Written on C#, using WebApi, RabbitMq, SignalR as main communication channels.

Personal results:
• Developed new authentication logic as a new micro service to increase authentication scalability and fault tolerance. Also authentication validations were moved from business layer to Api layer for better sustainability. Used .Net Core framework, Simple Injector, RabbitMQ, NLog for new service
• Participated in splitting legacy monolith service into micro services (payment, feed, authentication, auto pays, user blocking etc.) to increase whole system scalability, durability and fault tolerance. All new service built on .NET Core Framework. Used WebApi, RabbitMQ, Redis, NLog, Simple Injector and built-in DI in .net core
• Developed new logging system to analyze logs from all services, deployed it to local Nuget, so all of services can use it. Using library, we could logically link different Api calls, if they have same operation identifications, for better tracing logic flow (i.e. if some operation is divided into many Api calls), logging parameters is hidden in execution process flow (using CallContext and AsyncLocal), so there was no need to pass logging parameters directly in methods in business logic. Logging library based on NLog. All logs are written in JSON format with predefined set of fields for each log level. Later other systems put logs in Elastic Search, and via Kibana/Graphana we could analyze logs very easily
• Designed application architecture for new micro services according multitier architecture (Application layer, Business layer, Data access layer) for better service maintenance and readability
• Designed database structure using MsSql and code first pattern with Entity Framework.
• Designed micro services communication logic using WebApi and RabbitMQ
• Designed unit test using NUnit and MsTest frameworks
• Developed database migrations using Entity Framework

Development Environments: Visual Studio, VS Code, .NET Framework, .Net Core, WebApi, MsSql, Redis, RabbitMQ, EF/EFCore, Resharper, Git, NUnit, MsTes
