About Me

A brief overview of my approach and experience

Fullstack Developer with 5+ years of commercial experience. I specialize in backend development (Node.js, Go) and DevOps (Kubernetes, Docker, CI/CD). Focus — 80% backend.

I have worked in fintech (payment systems, cryptocurrency, billing) and real estate analytics (the #1 platform in Russia) handling up to 50,000 daily visitors. I have designed microservice architectures, implemented Event-Driven approaches, and set up monitoring and distributed tracing.

I also work with Telegram Bots, Telegram Mini App, React Native, and Electron. I actively leverage AI in development: building RAG pipelines, working with LLMs, Claude Code, and Cursor. I run my own project portal — webappmaster.ru.

Founder of two startups, author of open-source projects. I have managed development teams, value Agile practices, business outcomes, and clean scalable code. English — B1.

AI & Automation

AI-first approach in development and products

AI as a productivity multiplier

I actively integrate LLMs and AI tools into everyday development and products. I use AI not as a toy, but as a tool that significantly accelerates speed and quality of work.

RAG Pipelines

Retrieval-Augmented Generation for search and content generation based on proprietary data

AI Assistants in IDE

Claude Code, Cursor — daily tools for code generation, refactoring, and code review

Vector Databases & Embeddings

Semantic search, storage, and working with vector representations of data

ai-workflow.ts 
const pipeline = createRAG({
  embeddings: "openai",
  vectorDB: "pinecone",
  llm: "claude-3",
  chunking: "semantic",
});

const answer = await pipeline
  .retrieve(query)
  .augment(context)
  .generate();
