Greetings! I am Mahima Khera, a seasoned AI Developer, systems architect, and Full-Stack Engineer with 8+ years of experience building end-to-end AI applications. I specialize in Gen AI engineering, custom AI Agent development, and production-ready LLM architecture. I handle the complete development lifecycle from stateful LangGraph agentic workflows and Advanced RAG pipelines to robust Python backends, custom vector databases, and responsive Next.js user interfaces on secure AWS cloud infrastructure.

Core Services I Offer
→ Autonomous AI Agent Development: Architecting complex AI Agent systems, multi-agent orchestration, and agentic workflows using LangGraph, CrewAI, AutoGen, and Model Context Protocol (MCP) to automate business operations.
→ Advanced RAG and GraphRAG Pipelines: Building enterprise-grade Retrieval-Augmented Generation (RAG), knowledge graphs, and multi-stage reranking engines using LangChain and LlamaIndex to eliminate LLM hallucinations.
→ Production Voice AI Agents: Engineering ultra-low latency, real-time conversational Voice AI Agent systems using LiveKit, Vapi, Retell AI, and Deepgram APIs.
→ Full-Stack Gen AI Applications: Developing high-performance Next.js and React interfaces powered by scalable Python (FastAPI, Django) and Node.js microservices integrated with OpenAI, Anthropic, and local LLM APIs.
→ LLM Fine-Tuning and Cloud Deployment: Fine-tuning open-weight models (DeepSeek-R1, Llama 3.x/4) using Unsloth, LoRA, and vLLM, deployed seamlessly on AWS Bedrock and AWS SageMaker to slash API costs.
→ Workflow and AI Integration: Integrating custom AI models and n8n/OpenClaw automations directly into CRMs, webhooks, and operational workflows to streamline manual processes.

Deep Technical Expertise
→ Gen AI and AI Agent Frameworks: LangGraph | LangChain | CrewAI | LlamaIndex | Model Context Protocol (MCP) | OpenClaw | Prompt Engineering
→ Cloud AI and LLMs: AWS Bedrock | AWS SageMaker | OpenAI API | Anthropic Claude | DeepSeek-R1 | Llama 3.x/4 | Mistral | Ollama
→ RAG and Vector Databases: PostgreSQL (pgvector) | Qdrant | Pinecone | Weaviate | Milvus | SQLite | Redis Caching

→ Frontend and Voice AI: Next.js | React.js | TypeScript | Tailwind CSS | LiveKit | Vapi | Deepgram

Whether you need a full-stack Gen AI platform, a specialized AI Agent built with LangGraph, or a custom RAG solution on AWS, I deliver clean, scalable, commercial-grade code tailored to your business needs.

Let’s build something incredible. Introduce your project or invite me to apply!

Warm regards,
