Senior engineer with experience leading automation teams and building production systems end-to-end — from architecture design to deployment, observability, and operations. I focus on solving real business problems through technology: reducing manual work, increasing throughput, and building systems teams actually rely on.
My current work spans two domains: enterprise automation (AI pipelines, data workflows, integrations, IoT telemetry) and network security, where I develop backend systems for L3/L7 traffic filtering, service configuration, client monitoring, CAPTCHA generation, and TLS traffic interception tooling.
| ⚡ Backend & Platform | 🤖 Automation & AI | 📡 IoT & Embedded |
|---|---|---|
| High-load REST APIs (1000+ RPS) | Document processing & analytics | ESP32 firmware & telemetry |
| Multi-tenant RBAC systems | LLM pipelines, RAG, transcription | Binary protocols (TCP/UDP/BLE) |
| Developer SDKs & internal tooling | ETL, API integrations, BI delivery | Real-time sensor streaming |
| Observability & deployment pipelines | Scraping & geocoding services | Device management systems |
| ⚡ | Backend services handling 1000+ RPS with zero failed transactions |
| 📡 | Binary protocol for real-time IoT telemetry across TCP/UDP/Serial/BLE |
| 📦 | Chunked file uploads up to 5GB with circuit breakers and auto-recovery |
| 🚀 | Bot SDKs with zero-allocation architecture (29ns/message dispatch) |
| 🤖 | AI agent pipelines using LangChain/LangGraph, RAG, and MCP |
| 🛡️ | L3/L7 traffic filtering backends — configurator, client monitoring, CAPTCHA, TLS interception |
| 🏭 | 18+ production automation services with ~13M RUB/year estimated savings |
| 📊 | 30+ BI dashboards for operational and management analytics |
