Solution Architect, 10+ years of experience. I care about solving problems, not which technology to use.

Tech: .NET / C# | SQL (SQL Server, PostgreSQL) | Azure | Docker | Messaging (RabbitMQ, MQTT) | IoT (Arduino, ESP32) | Git | AI

Problems I solve
Monolithic & legacy systems
  • Refactoring to clean architecture, introducing a domain model
  • Shortened deployment cycle from monthly to 2–3 weeks

Elinkx – enterprise application

Systems that don't talk to each other
  • End-to-end integration of ERP, e-commerce, and internal services
  • Business process automation across platforms, including AI

Elinkx – e-commerce & ERP integration

Mission-critical systems
  • Custom heating controller – design, implementation, operation
  • Reverse-engineering protocols, Home Assistant integration
  • Remote monitoring, data collection, automation

SmartHome – Arduino, ESP8266, MQTT

Poor performance
  • Identifying bottlenecks, large-scale refactoring and optimization
  • From database queries to application-wide architecture

Elinkx – long-running systems

Team without direction
  • Dev team leadership, code review, culture of continuous improvement
  • CI/CD automation – faster and safer deployments

Elinkx – team lead & DevOps

Making sense of data
  • Research: image analysis, signal classification, data compression
  • Data-driven decision making – applied in commercial projects as well
