Need an AI SaaS built, LLM integrated into your app, or business workflows automated? You're in the right place. I'm a full stack AI developer with 10+ years building production-ready AI products not demos that fall apart when real users show up. I work across MERN stack, AI agents, RAG pipelines, and automation, so you get one engineer who owns the whole build instead of three specialists who've never spoken to each other. What I build: **Full Stack Web Development & AI SaaS: I build full stack web applications, AI SaaS platforms, custom web apps, and MVP products using MERN stack MongoDB, Express, React, Node.js as well as Next.js, TypeScript, Python, FastAPI, and Django. Whether you need a React developer for your SaaS platform, a Node.js backend developer for your API, a full stack developer for your CRM platform, a web application engineer for your marketplace, or an MVP developer for your startup. I build it from scratch, production-ready, scalable, and secure. **AI Agent Development & RAG Pipelines: I build AI agents, autonomous AI systems, and RAG pipelines using LangChain, AutoGen, CrewAI, and Claude. My agents don't just respond to prompts they plan, execute multi-step tasks, handle exceptions, and report outcomes without manual triggering. I also build MCP servers and Model Context Protocol integrations for AI agents that need structured tool access. **LLM Integration & AI Application Development: I integrate OpenAI GPT-4o, Claude API, and Gemini into web applications, SaaS platforms, and business tools. Whether you need an OpenAI API integration expert, a ChatGPT API developer, a Claude AI integration developer, a GPT-4o application developer, or an OpenAI Assistant API developer. I build clean, production-grade integrations with proper error handling, rate limit management, streaming responses, and evals built in from day one. **AI Automation & Workflow Development: I build AI automation workflows, AI agents, and business process automation using n8n, Make com, and Zapier. Whether you need an n8n automation expert, an n8n workflow developer, an n8n AI agent builder, a Make com automation expert, a Zapier automation expert, or an AI workflow engineer. I build it end to end with proper error handling, logging, and documentation so your team can maintain it without me. **No-Code to Custom Code Migration: Built on Bubble, Webflow, Lovable, FlutterFlow, Replit, or Base44 and hit the limits? I migrate your no-code product to a scalable, secure, production-ready MERN or Next.js codebase without losing what's already working. Why clients pick me: Most developers integrate an API and call it done. I architect the full system proper error handling, rate limit management, monitoring so it still works when 500 real users hit it, not just in the demo. **Tech Stack** Frontend: React · Next.js · TypeScript · Tailwind CSS · Redux Backend: Node.js · Express · Python · FastAPI · Django · Laravel · GraphQL · REST APIs Database: MongoDB · PostgreSQL · MySQL · Redis · Prisma · Supabase · Firebase AI: OpenAI GPT-4o · Claude API · Gemini · LangChain · AutoGen · CrewAI · LlamaIndex · Pinecone · Weaviate · Hugging Face · Ollama · Claude Code · Vertex AI Automation: n8n · Make com · Zapier · MCP · Webhooks DevOps: AWS · Vercel · Docker · GitHub Actions · CI/CD · Linux VPS **Industries: Fintech · Health tech · B2B SaaS · Marketplace · E-commerce · On-demand · EdTech · Logistics · Legal tech · HR tech · Real estate tech · Travel tech · CRM platforms · Internal tools Got an existing app that needs fixing, scaling, or AI added? I handle that too. 📩 Message me first tell me what you're building and what's blocking you. I respond within 1 hour.
