CV
Over four years in software development. Primary language — Python, specializing in backend, APIs, AI integrations, and automation. Capable of managing a project from requirements to production and beyond.
Experience both in teams (full-time positions) and fully solo — from architecture to deployment and maintenance. Strong understanding of business processes, easily build rapport with clients and dive into project details.
Actively work with neural networks — both as a development tool (Claude Code, agentic development, full development pipeline through AI agents) and as part of the product (LLM integrations, semantic search,
embedding models, prompt engineering). Over the years I've tried numerous approaches and variations — I know the ins and outs. Have shipped products to market developed in this format.
Constantly improving my skills and learning new technologies for more efficient task execution.
Recent projects:
Voice AI assistant for veterinary clinics. Built on a RAG system with telephony integration (gRPC, SIP) — receives client calls, schedules appointments, provides consultations based on a verified knowledge base, and selects appropriate actions during conversations. Semantic search via Qdrant, LLM integration, full AI pipeline from speech recognition to response generation. Explored numerous variations of working with neural networks on this project.
Search engine built on Elasticsearch for a large-scale website. Multiple search algorithms, complete backend service for frontend integration.
AI-powered contextual advertising platform for Telegram. Semantic search, neural network integration, B2B web application with admin panel, Telegram client fork, full business logic, solo development and project management.
Many other projects.
