🧭 **I design and build agentic systems that survive production — observable, evaluable, and maintainable by your team after I leave.** 🏅 **Expert-Vetted | 100 % Job Success | Physics PhD, $90K+ earned. Recent: VIVIA (real-estate multi-agent platform, WhatsApp + voice + CRM) and a Neo4j-backed RAG pipeline rated ★5.0 Agents fail where teams don't look: prompt fragility, silent regressions, untraced failures, no fallback paths. That's the first thing I plan for. 🏗️ **Architectural scope I cover** - Multi-agent orchestration with LangGraph — explicit state machines, checkpointing, human-in-the-loop - GraphRAG on Neo4j — entity resolution, hybrid retrieval, explainable reasoning paths - Agent evals & observability — LangSmith / custom tracing, regression suites, cost dashboards - Production deploys — vLLM / Docker / Kubernetes, load-balanced inference, fallbacks across providers - Integration layer — WhatsApp, Twilio voice, CRM APIs, MCP servers, webhook resilience 🔬 **Background** PhD in Physics + years as a quantitative researcher. I treat agent behavior as a measurable system — I run experiments, log everything, and challenge claims that don't come with numbers. ✅ **Recent work** - **VIVIA** — Multi-agent real-estate platform: channel-agnostic core, per-agency scoping, lead follow-up sync, voice calls, CRM integration.
