Software Engineer \| LLMs · RAG · LangGraph · FastAPI \| Open to Work — Immediate Joiner

## About

Currently available for immediate joining\. I build AI systems with production engineering instincts — where latency, caching, and observability are design requirements, not afterthoughts\. Recent AI projects: → Omni\-Router — Production LLM gateway with semantic caching \(FAISS \+ Redis\), intent\-based model routing \(NearestCentroid classifier benchmarked against 6 algorithms\), and async quality evaluation via ARQ \+ DeepEval\. Simple queries hit cache and skip LLM inference entirely\. MLflow tracks every latency, cost, and eval metric\. → Legal Intelligence — Contract Risk & Dependency Intelligence System built on a LangGraph state machine with hybrid retrieval \(Qdrant semantic search \+ Memgraph graph traversal\), multi\-hop dependency reasoning across legal corpora, intelligent query routing \(semantic / graph / both / direct\), self\-correcting rewrite loop, real\-time SSE execution timeline, and full observability via Arize Phoenix \+ Ragas evaluation\. → Voice AI Assistant — Sub\-300ms STT → streaming LLM → TTS pipeline over WebSockets\. Concurrent multi\-session architecture with session isolation\. Engineering background: 3 years building real\-time systems, distributed caching layers, and concurrent architectures in production — the same instincts that drive semantic caching, latency budgets, and observability in my AI projects\. Certified: RAG & Agentic AI Professional · Generative AI Engineering Professional \(IBM, 2025\) Specializations: LangGraph · LangChain · CrewAI · AutoGen · Transformers · Fine\-tuning · Vector DBs Open to AI Engineer / LLM Engineer roles\. ajeetkrup401@gmail\.com
