I build systems that: ✅ Work reliably in production ✅ Scale as your business grows ✅ Integrate with your existing tools ✅ Deliver measurable business value ✅ Are maintainable and cost-efficient ## Industries I Work With ✔ SaaS Startups ✔ AI Product Companies ✔ E-commerce Businesses ✔ Consulting Firms ✔ Enterprise Teams ✔ Operations & Support Teams ## Let's Build Something That Creates Real Business Impact Whether you're building an AI product, implementing RAG, developing AI agents, or automating business processes, I can help you design and deploy a solution that works in production. Send me a message with your project idea, and I'll suggest the best approach to get started.

Overview: You have an AI product idea — or an existing product that needs AI built into its core. You need someone who won't just write code, but make the hard architectural decisions that determine whether your product scales or breaks at 10,000 users. That's what I do. I've shipped 5 AI-native products in the last 2 years, each running in production with real users today. Not prototypes. Not demos. Production systems handling real data, real money, and real compliance requirements. Recent results: → Built an AI conversation intelligence platform that analyzes calls across 19 dimensions in real-time — now processing hundreds of conversations daily for a US-based SaaS company → Delivered an AI medical education platform with 11 LLM-powered endpoints, integrating clinical evidence from randomized controlled trials — used by healthcare professionals for continuing education → Shipped an AI learning platform with 9 specialized AI pipelines — 500+ study hours saved for users within months of launch → Architected an AI-powered industrial support system with vector search and multi-tenant isolation — deployed across operator, technician, and admin roles for a European client What makes me different from other AI developers: Most developers bolt AI onto existing products as a feature. I architect systems where AI is a core capability — from database schema to user experience. Every project I deliver includes production infrastructure (CI/CD, monitoring, error tracking), not just application code. I also run a team at Growth Loops Technology, which means I can scale up when your project needs it — without you managing multiple freelancers. I'm the right fit if you need: → An AI-native product built end-to-end (backend, AI pipelines, deployment) → LLM integration done properly (structured output, RAG, multi-stage pipelines) → A senior architect who can own technical decisions and communicate clearly → Someone who ships on schedule and writes code that holds up in production Technical depth (for the engineers reading this): Backend: NestJS, Node.js, TypeScript, Python, FastAPI, Django AI/ML: GPT-4o, Claude, LangChain, LangSmith, Whisper, AssemblyAI Data: PostgreSQL, Redis, BullMQ, Pinecone, OpenSearch, Meilisearch Infra: Docker, GitHub Actions, AWS, Cloudflare R2, Sentry 15+ years of software engineering. Every project delivered with authentication, async job processing, multi-tier caching, and production monitoring baked in from day one.

Build production-ready AI agents, RAGs with LangChain + GPT for SaaS companies. Cut dev time 50% and scale to tens of thousands of users. Recent client feedback: “Zak was awesome! He delivered exactly what I asked faster than I expected! He is extremely knowledgeable” I don’t just write code, I solve business problems. Whether you need an AI agent handling customer inquiries 24/7, a custom workflow that eliminates manual tasks, or a scalable web application, I deliver solutions that save time and generate ROI. What I specialize in: 🤖 AI Agents & Automation by • Custom ChatGPT/Claude integrations • Workflow automation (Zapier / n8n alternatives) • Data processing pipelines • Lead generation bots ⚡ Modern Full-Stack Development Turning AI-generated prototypes into real applications - Yes, Vibe coding got you 80% there in 2 hours, but now you need the other 20% that actually matters: security, authentication, error handling, database design, and deployment that doesn’t crash at 3am • Next.js 14+ with App Router • React/TypeScript applications • Node.js/Python APIs • Real-time applications (WebRTC, WebSockets) ☁️ Cloud & Infrastructure • AWS serverless architecture • Database optimization (PostgreSQL, DynamoDB) • API design and integration • Performance optimization My approach: Fixed-price or hourly projects with clear deliverables. You get working software, not just hours logged. I handle the technical complexity so you can focus on growing your business. Ready to automate your next bottleneck or build something that scales? Let’s talk.

Hey, I’m Chaitanya Bandawat, a Jaipur-based AI geek who lives for crafting smart, scalable solutions from the ground up. I’m all about building RAG chatbots, voice AI agents, and full-stack platforms with tools like Python, Java, JavaScript, Flask, FastAPI, React, and Streamlit. I’ve got hands-on experience with LangChain, Pinecone, FAISS, Gemini, Grok, Claude, GPT and HuggingFace, creating everything from real-time conversational bots with ElevenLabs TTS to data-heavy pipelines using Playwright and Scrapy. At Accenture, I led projects that cut website load times from 10 to 3 seconds and sped up delivery with agile practices. As a freelancer, I’ve built cool stuff like Verdict Vault—a RAG pipeline for querying documents—and Anita, an emotionally aware chatbot with multilingual voice output. I’ve worked across legal, finance, and support, nailing rapid prototypes and tight API integrations. I’ve got a Master’s in Data Science from Cardiff University (8/10 GPA) and a B.Tech in Computer Science from Banasthali Vidyapith. When I’m not coding, I blog about AI, breaking down tools like LangChain and Pinecone into simple, actionable guides for devs. I’m hooked on solving tough problems and turning ideas into tech that makes a difference.
