Hi there, I'm Sergey Kosovsky!

Senior Golang Developer | AI & Backend Architecture

I'm a backend engineer specializing in high-load distributed systems and AI-driven solutions. Currently, I build scalable core microservices at Ozon Tech (serving 100M+ users).

My focus is at the intersection of Backend Engineering and Applied AI — I design robust architectures using Go, Kafka, and gRPC, while actively developing tools for LLM integration, Agentic workflows, and prompt engineering.

🚀 Featured AI & Go Projects

Here are some of my recent open-source tools focused on AI integration, agent orchestration, and backend infrastructure:

  • 🛡️ guardy — Robust validation and guardrails for AI/LLM responses and data flow.
  • 🧰 toolsy — Tool-calling utilities and integrations for extending AI agent capabilities in Go.
  • 🌊 flowy — Type-safe engine for managing complex agentic workflows and execution pipelines.
  • 💬 prompty — Prompt templating, versioning, and workflow management for LLM applications.
  • 🧠 contexty — Token budget allocation, context packing, and memory-aware prompt construction.
  • 📚 ragy — Lightweight RAG and semantic memory engine for AI applications in Go.
  • 📊 metry — Observability and LLMOps toolkit for tracing, metrics, and AI workflow monitoring.
  • 🧭 routery — Routing, fallback, and resiliency utilities for backend and AI orchestration.

(Feel free to explore the code and contribute!)
