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.

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

• 🛡️ guardy — Typed validation pipelines and guardrails for AI/LLM responses and data flow.
• 🧰 toolsy — Typed AI tools with JSON Schema, argument validation, and streaming execution in Go.
• 🌊 flowy — Type-safe graph execution and durable orchestration for agentic workflows.
• 💬 prompty — Prompt management, templating, and unified access to multiple LLM providers.
• 🧠 contexty — Typed LLM context management with token budgets, context packing, and checkpoint storage.
• 📚 ragy — Typed retrieval toolkit for semantic search, RAG pipelines, and hybrid retrieval.
• 🗃️ memy — Typed knowledge lifecycle with host-approved updates, canonical storage, scoped recall, and revocation.
• 🧪 evaly — Typed evaluation with immutable datasets, isolated runs, graders, comparisons, and bounded optimization.
• 📊 metry — OpenTelemetry and LLMOps toolkit for tracing, metrics, and AI workflow monitoring.
• 🧭 routery — Generic routing, fallback, and resiliency utilities for backend and AI orchestration.
