Designed and implemented a .NET 8 microservice for worst-case bridge load analysis using Kafka-based computation pipelines. Built a layered domain model with DDD practices and CQRS-inspired immutability rules to stabilize evolving requirements. Achieved major performance gains by reducing calculation complexity and optimizing data structures for the hot path using EF Core with PostgreSQL. Also worked with GitLab CI/CD and Grafana for delivery and observability.

Delivered architecture and backend features for a construction tender platform using ASP.NET Core and database-backed services. Worked on versioning improvements to make the source of truth more readable and reduce recurring production issues. Implemented customer PDF reporting, Redis-based production paths, and cleaned up SQL and business logic across a large legacy codebase. Built/extended frontend component behavior using Ext JS and supported real-time features with SignalR.

Contributed to backend architecture for a European online testing product using ASP.NET Core services in containerized environments. Built and integrated messaging and real-time communication components, including RabbitMQ, Redis, and SignalR, and coordinated with English-speaking clients. Developed from scratch a backend for an online library, covering application and database design, JWT authentication, search functionality, and storage via S3 or local files. Added tenant access controls based on university IP whitelists for campus Wi‑Fi access.

Worked on a civil infrastructure product inside mos.ru, implementing new features and performing refactoring. Participated in migrations from ASP.NET to ASP.NET Core, improving maintainability and modernization of the backend. Used Redis to support performance and operational requirements for the platform.

Developed and maintained an ASP.NET-based CRM built with DevExpress XAF. Optimized stored-procedure performance in MS SQL and delivered new web services. Implemented Telegram delivery functionality and integrated it into the system workflows.

Built and shipped modules for a desktop line-of-business application under tight time constraints. Implemented custom UI controls and extended functionality using C# with a DevExpress-based desktop stack. Worked with MS SQL and Entity Framework patterns for data access and application behavior.

Developed a .NET desktop client and supported integrations involving Verilog/Altium workflows. Performed Windows administration tasks as part of maintaining and operating the environment. Contributed to development using C# and supported technical interoperability for engineering tooling.
