Pankaj K.
Full Stack AI SaaS Developer | AI Agents, Voice AI, Automation, RAG
⚡ I build complete AI-powered SaaS products and automation systems — from architecture to deployment — on a proven Next.js, React, Node.js and Python foundation. Not one-off fixes: full systems I own end to end. ✅ Top Rated · 100% Job Success · 4+ years full-stack I take projects from idea to live product — backend, frontend, database, AI layer and deployment — so you work with one developer who owns the whole build, not a patchwork of freelancers. 🚀 What I build AI voice agents & chatbots — Twilio agents that answer calls, qualify leads and book appointments 24/7; chatbots that pre-qualify before a human steps in. AI on your own data — RAG systems and document Q&A so your team queries your own files, docs and knowledge base with real accuracy. CRM & workflow automation — GoHighLevel, n8n, Make, Zapier connecting your CRM, forms, calendar, payments and messaging so leads get captured and followed up on their own. Full-stack SaaS platforms — React, Next.js, Node.js, NestJS, Python/FastAPI, PostgreSQL, Supabase. MVPs, dashboards, client portals, REST APIs, auth and role-based systems — designed, built and deployed to production, not handed off halfway. 🛡️ How I work Scope agreed in writing up front — "done" is defined on day one, not argued at the end. Delivered in phases — you see something working early, not after weeks of silence. I own the full stack, so there's no "that's not my part" when something breaks. Honest advice — I'll tell you when a simpler solution is the better one. 💬 What clients say "Pankaj has solved us some issues that several others couldn't." "Quickly identified the bottleneck in our API and fixed the data validation issues." "Very professional, communicates well, and delivers high-quality scalable code." 🔎 Skills: Next.js, React, Node.js, NestJS, Express, Python, FastAPI, PostgreSQL, Supabase, RAG, LangChain, Vector Embeddings, AI Agents, AI Voice Agents, Chatbots, LLM Integration, Conversational AI, Twilio, GoHighLevel, n8n, Make, Zapier, Workflow Automation, REST API, SaaS Development, Full-Stack Development, MVP Development, API Integration. 📩 Planning a full build or a serious automation system?
