Artificial Intelligence Developer | AI Agent, LangChain, n8n, VAPI, Retell AI


About this Gig
I build AI agents and full stack applications that do real work, booking appointments, qualifying leads, answering customers, and automating the repetitive tasks that quietly cost your business hours and money every single day. Here's the simple math I walk every client through: if your team spends 20 hours a week on manual follow-ups, data entry, or answering the same questions that's 1,000+ hours a year. Automation that costs you once keeps paying you back every month after. I've helped small and mid-sized businesses across industries, healthcare clinics, real estate agencies, e-commerce stores, service businesses, and growing startups, turn that lost time into measurable ROI: faster response times, more booked appointments, fewer missed leads, and lower operational costs. ═══ HOW I CAN HELP YOU ═══ 🤖 Losing leads because nobody responds fast enough? I build AI agents and chatbots, voice agents that answer your calls (Vapi, Retell AI), WhatsApp and website chatbots that capture and qualify leads 24/7, and RAG-based assistants trained on your own business documents using LangChain and vector databases. Leads answered in under 5 minutes are far more likely to convert, my agents respond in seconds. ⚙️ Team buried in repetitive admin work? I automate it, appointment booking, lead follow-ups, invoicing, data entry, and email management using n8n, Make dot com, and custom Python automation. One workflow I build once runs for you every day after, without sick days or salary. 💻 Need software built and built right? I develop full stack web applications, SaaS products, dashboards, and client portals using Python (FastAPI, Django) and JavaScript (React, Next.js, Node.js) with PostgreSQL, MongoDB, and cloud deployment on AWS. Built to scale with you, not to be rebuilt in a year. 🗂️ CRM doesn't fit how you actually work? I build custom CRMs and internal tools designed around your real workflow, and integrate AI into the tools you already use: GoHighLevel, HubSpot, Stripe, Twilio, Google Workspace, Calendly, and industry-specific platforms via REST and GraphQL APIs. 🧭 Not sure what to automate first? I also offer AI consulting and automation audits, a clear, honest roadmap of what will actually save you money, and what isn't worth automating yet. ═══ MY TOOLKIT ═══ Languages: Python · JavaScript/TypeScript AI & Agents: LangChain · LangGraph · OpenAI (GPT-4) & Claude APIs · RAG Pipelines · Pinecone · ChromaDB · Vapi · Retell AI · OpenClaw · CrewAI · AutoGen · LLM Automation: n8n · Make dot com · Zapier · Custom Scripts Web: React · Next.js · Node.js · FastAPI · Django · Tailwind Data & Cloud: PostgreSQL · MongoDB · Redis · Supabase · AWS · Docker ═══ HOW I WORK ═══ I don't just write code, I start with your numbers. Every project begins with two questions: "What task do you wish would just handle itself?" and "What is that task currently costing you?" Then I build exactly what closes that gap. No overengineering, no jargon, no disappearing mid-project. You get clear communication, honest timelines, and a solution you actually understand. 📩 Send me a message with a quick description of what you'd like to automate or build. I usually respond within a few hours, and the first consultation is always free. Let's build something that works while you sleep, and pays for itself while it does.
