Chetan M.

I build production-ready AI applications, LLM systems, RAG solutions, AI agents, and AI-powered SaaS products. If you need an experienced engineer who can take an AI product from architecture and development through integrations, cloud deployment, testing, and ongoing improvements, I can help. My core expertise includes: ✓ Generative AI & LLM Applications ✓ RAG (Retrieval-Augmented Generation) ✓ AI Agents & Agentic AI ✓ OpenAI APIs and LLM integrations ✓ LangChain, LlamaIndex & AutoGen ✓ Prompt Engineering ✓ Embeddings & Vector Search ✓ AI Knowledge Bases ✓ AI Chatbots & AI Assistants ✓ AI Workflow Automation ✓ Python, FastAPI, Django & Django REST Framework ✓ React, TypeScript & JavaScript ✓ REST APIs & Third-Party API Integrations ✓ PostgreSQL, MySQL, MongoDB & Redis ✓ AWS & Microsoft Azure ✓ Docker, Kubernetes & CI/CD I also have strong full-stack, backend, cloud, DevOps, database, and system architecture experience. This allows me to build the complete production system around the AI—not just connect an LLM API. What I Can Build • LLM-powered SaaS applications • Enterprise RAG and knowledge-base systems • AI chatbots and intelligent assistants • AI agents and agentic workflows • Multi-agent AI systems • AI-powered search and semantic search • Document intelligence and data extraction • AI customer-support systems • AI workflow automation • AI-powered business applications • AI features for existing SaaS products • AI + CRM and third-party API integrations • Secure AI APIs and backend platforms • Production-ready AI applications My Engineering Approach I focus on building reliable, maintainable, production-ready AI systems—not just prototypes or simple prompt integrations. I can take ownership of the complete development lifecycle: Architecture → Backend → LLM Integration → RAG → AI Agents → APIs → Database → Frontend → Cloud → CI/CD → Testing → Production Support I care about scalability, security, performance, observability, clean architecture, automated testing, and maintainable code. Additional Expertise I have strong experience with: • Microservices and distributed systems • RESTful APIs and asynchronous processing • Authentication, OAuth 2.0, JWT & RBAC • Event-driven architecture • AWS and Azure • Docker and Kubernetes • CI/CD and DevOps • Database design and optimization • API integrations and workflow automation • Healthcare applications, FHIR APIs and secure healthcare data processing • Power BI and data analytics Why Work With Me? You don't need multiple developers for the AI, backend, frontend, integrations, and deployment. I can work across the entire stack and take ownership of delivering the solution. I'm especially interested in long-term engagements where I can become a reliable engineering partner, take ownership of features, improve an existing AI product, and continuously deliver new functionality. If you have an existing AI application that needs an experienced engineer, or you're looking to build an AI product from the ground up, feel free to message me. Let's build something reliable, scalable, and production-ready.
