Hire the Best Travel Planners

Need an AI agent, voice bot, or SaaS product that actually ships to production—not another demo that dies after the pitch? That's where I help. I recently built an AI voice receptionist (live at callersync..com) that answers calls in real time, books appointments, and logs every conversation automatically. I've also helped clients reduce manual workloads by 60% through automation and built backend systems handling 100,000+ API requests per day. ⭐ What clients say: • "Expert in Next.js & React.js — dedicated resource." • "Quick turnaround, very talented." • "Takes ownership and enhances performance." 💼 What I build: • AI Voice Agents & Chatbots — OpenAI Realtime, Claude, Whisper, Deepgram, ElevenLabs, Twilio • AI Automation & Workflows — LangChain, n8n, RAG systems, document intelligence • Full-Stack SaaS Applications — Next.js, React, Node.js, TypeScript, PostgreSQL • APIs & Integrations — Stripe, OAuth, Webhooks, CRMs, scheduling platforms • Scalable Cloud Infrastructure — AWS, Cloudflare, Docker, Vercel, CI/CD ⚙️ Tech Stack: React • Next.js • TypeScript • Node.js • NestJS • Python • PostgreSQL • MongoDB • Redis • OpenAI • Claude • LangChain • AWS • Docker • CI/CD ✔ Why clients hire me: • 25+ successful projects delivered • 93% Job Success Score • Fast communication and clear updates • Production-focused development, not prototypes • Proactive suggestions that improve the product and reduce long-term costs Whether you have an AI idea, a half-built application, or a manual process that's slowing your team down, send me a message. I'll walk you through exactly how I'd build it, what challenges to expect, and the fastest path to production.

Your AI demo works perfectly. Then real users show up, the inputs get messy, and it falls apart. I build the version that holds up in production. For three years I have been the engineer behind live AI platforms that real people use every day, with 100% Job Success on every contract I have finished. I build the whole product, not just an AI feature bolted onto someone else's app. The generative AI, the agents, the backend, the frontend, the database, payments, and deployment. Hand me an idea or a half working prototype and I take it to something live and reliable. WHAT I BUILD → Generative AI apps and chatbots, with the model, the product, and the UI built to work as one → AI agents and multi agent systems with LangGraph and LangChain, tool calling, and human in the loop → RAG and document intelligence with ingestion, OCR, vector search, and answers that cite their source → Full stack web and AI apps on Next.js and FastAPI, with auth, billing, dashboards, and multi tenant setups → Cloud deployment on AWS and GCP with Docker and CI/CD RECENT WORK → Healthcare AI platform serving international patients. Built the chatbot, provider matching, multilingual support, anti spam, and Stripe payments, all running in production. → Government document intelligence system. Found that pages with complex tables were being dropped silently and making the model invent answers, then fixed it by reading those pages as images so nothing is lost and every answer stays grounded with citations. → Multi tenant AI SaaS with multi agent workflows, tool calling, and a human approval step before anything important happens. → Voice controlled chess platform combining speech to text, an LLM, and a chess engine. HOW I WORK → Scope first. We agree on the goal and what success looks like, in writing, before any code. → Weekly sprints. You see something working every week, not status updates. → Production from day one. Logging, tests, and guardrails built in, so you can trust it live. → Claude Code daily on the Max plan, so I move fast without cutting corners. Clear communication, no disappearing mid project, and a system your team can actually maintain after handoff. WHO THIS IS FOR I am a good fit if you have a real problem and want a product your own team can keep running after I hand it over. I am probably not your person if you only want the cheapest possible quote or you are still just experimenting with no clear use case.
