Senior Software Engineer

14+ years building distributed systems that don't break under load — and thelast two years building systems that think. I take products from nothing to production. At RingCentral I owned the parts of the platform other teams depend on — Kafka pipelines, 21 microservices on a150+ service Kubernetes cluster, 99.999% SLA, 10M users. On my own products I doall of it: architecture, infra, billing, the agent layer, the frontend. The kind of work where a mistake at 3am pages someone — and that someone is me.

Shipped inside companies: — 21 microservices under full on-call ownership at RingCentral, 99.999% availability — LLM automation at RingCentral — multi-agent PR review adopted by 150+ engineers, plus an automated vulnerability-fix pipeline (scanner → ticket → agent → PR) — 40% infra cost cut via serverless migration (NestJS + AWS Lambda + Terraform) at Informa
— 95% faster report loads at Sberbank via query profiling and async redesign

Built and run solo, 0→1:
— diffray.ai — code review through 30+ specialized AI agents (security, perf, architecture)
— telagon.io — analytics + ad marketplace over 1.4M+ Telegram channels; agentic search, ClickHouse, pgvector (Go, Next.js) — privatclaw.com — deploy your own AI Telegram bot in 3 seconds; provisioning + billing — reelmente.app — a video agent for retail

I've also been a technical co-founder before (StreamEats, ~2 years) — owned architecture, infra, partner integrations, and hiring.
