Dmitry Gusarov

Software Architect · Senior Software Developer

Programming since 2000. Production software since 2005.

I design and build software systems: backend and distributed services, developer platforms, and the infrastructure that keeps them fast and testable. Most of that work is on .NET, across the full stack from storage and messaging to the browser.

For the last few years a large part of my work has been LLM engineering. I treat language models as engineered system components rather than chat boxes: custom agentic loops, orchestration, tool protocols, evaluation and the plumbing that makes them dependable inside real products.

I run Gusarov Inc., the umbrella under which my applications, projects and businesses are published.

Focus

  • Software architectureDesigning systems that survive growth: boundaries, contracts, data flow and the trade-offs behind them.
  • Distributed and backend systemsServices, messaging, event sourcing and CQRS, consistency models, offline-first synchronisation.
  • .NET platformTwo decades on the Microsoft stack, from .NET Framework to modern .NET, Blazor and native AOT.
  • Full-stack engineeringEnd-to-end ownership from storage and APIs to web and mobile clients.
  • Infrastructure and deliveryBuild systems, CI/CD pipelines, containers, cloud and edge networking, build performance at scale.
  • Performance and testing systemsProfiling, benchmarking, acceptance suites and the tooling that keeps large solutions honest.
  • LLM engineeringLanguage models as system components: prompts as interfaces, structured output, evaluation, cost and latency control.
  • Agentic systemsCustom agentic loops, orchestration of tools and sub-agents, and the guardrails that make them safe to run unattended.
