Most engineers plateau at Senior. I help you break through to Staff and Principal. 13 years of backend engineering, AI systems, and production-scale architecture. I've scaled systems from 60 to 5,000 concurrent connections, reduced infrastructure costs by 50%, and processed 1M+ real-time events per day. I've built RAG-based LLM applications, real-time WebSocket APIs, and microservices at scale. Currently Staff Engineer at Gruve.ai — building AI-powered backend systems and CLI tooling for enterprise clients. I can help you with: → System design & architecture reviews → Backend engineering (Node.js, Python, TypeScript, Java) → AI/LLM integration (RAG, LangChain, vector DBs) → Career guidance for senior/staff engineering roles → Mock interviews for backend & system design rounds
