What I'm looking for

I want to own architecture end-to-end for distributed, event-driven platforms—scalable, observable, and fault-tolerant. I bring an AI-assisted delivery workflow where I specify, review, and safely merge—building cloud backends and multi-platform products.

I’m a Solutions Architect with 15+ years designing and shipping distributed, high-load systems from concept to production. I specialize in event-driven architecture, real-time messaging, and fault-tolerant system design across cloud backend, mobile (iOS/Android), and desktop platforms.

I build systems end-to-end with deep ownership: architecture, decomposition, and precise specifications. Then I use an AI-assisted delivery workflow where AI agents implement features and automated tests under my review—so I can run 10+ personal production systems in parallel at a fraction of traditional team cost.

Recently, I designed and delivered a company-wide Enterprise Data Bus on Apache Kafka, running on Kubernetes with GitLab CI/CD and Prometheus/Grafana observability. I also architected a real-time data exchange gateway between mos.ru and company platforms, synchronizing homework and performance data via Kafka.

I’ve also shipped fault-tolerant services like a License distribution and validation platform with centralized access control. Across my portfolio, I’ve built multi-platform messaging (Elixir/Phoenix, WebRTC, PostgreSQL, Swift/SwiftUI, Kotlin/Compose), VPN infrastructure over MQTT with E2E encryption and failover, and voice AI services using GSM gateways, Whisper/VAD/STT, and LLM toolchains.
