👋 Hi there, I'm Siva Sai Krishna Yenugu! (ysskrishna)

🚀 AI-Focused Full Stack Developer | Founding Engineer | IITM Graduate | Bengaluru, India 🇮🇳

I build AI agents, RAG systems, and robust backend services that power modern web experiences. With deep expertise in AI/ML integration (LangGraph, LangChain, OpenAI), Python (FastAPI, Flask), Node.js, and cloud infrastructure, I architect intelligent solutions that combine cutting-edge AI with scalable engineering.

What I build:

🤖 AI agents & automation - Autonomous agents (LangGraph, Playwright), browser automation, vision-based perception, and Agent Skills for coding assistants
🔍 RAG & retrieval systems - Embeddings, semantic & vector search, vector stores (Chroma, Pinecone, pgvector), multilingual and multimodal retrieval, RAGAS evaluation, and RAG-powered chatbots
🔧 High-performance APIs - RESTful services, GraphQL endpoints, and microservices
🗄️ Data-driven backends - PostgreSQL, MongoDB, Redis, Elasticsearch, ChromaDB integrations
☁️ Cloud-native systems - AWS, Docker, CI/CD pipelines, and serverless architectures
🚀 Scalable solutions - Message queues, caching strategies, and performance optimization

Currently: Building AI agents & RAG experiments, robust backend systems, and contributing to open-source projects.
