I will build an ai chatbot with openai or claude for your website
Victor Martinez
About this gig
Need an AI assistant that actually works for your business? You're in the right place.
I build custom AI chatbots and voice agents powered by OpenAI, Claude or Gemini integrated into your website, WhatsApp, Telegram or even outbound phone calls.
Real production AI system: Markulia
A platform where users create AI voice agents that call leads automatically (Twilio + ElevenLabs + LLMs) and run sales campaigns end-to-end. That same tech goes into every project.
What I can build for you
AI chatbot on your website (RAG trained on your docs)
WhatsApp / Telegram / SMS automated assistants
Voice AI agents that call leads (like Markulia)
Customer support bots with CRM sync
Lead-capture and qualification flows
Internal automations (Slack, n8n, OpenAI API)
Stack
OpenAI · Claude · Gemini · LangChain · Node.js · Python · Twilio · ElevenLabs · n8n
Important
You provide your own OpenAI / Claude API key. Usage costs are paid directly by you to the provider (usually $1-20/month for small businesses).

👋 Hi! I'm Víctor, a full-stack web developer from Spain.
I build modern, responsive websites and SaaS dashboards using React, Node.js and clean code — not templates. My latest project, Markulia, is a SaaS platform I built end-to-end: React frontend, custom Node.js API, real-time quota system, admin panel, Stripe billing and VPS deployment.
🛠️ Stack: React · Node.js · REST APIs · Stripe · Tailwind · OpenAI/Claude APIs
I also integrate AI into web apps: chatbots, automations, LLM features.
✅ Clear communication · On-time delivery · Revisions included

FAQ
Who pays for the OpenAI / Claude API usage?
You do — directly to the AI provider with your own account and API key. I'll guide you through creating the account (5 min). Usage is usually $1-20/month for small businesses.
Which AI models do you support?
OpenAI (GPT-4, GPT-5), Claude (Sonnet, Opus), Gemini and open-source options via Ollama. I recommend the best one based on your use case and budget.
Can the bot be trained on my own data?
Yes — using RAG (Retrieval-Augmented Generation) the bot can answer using your PDFs, website, FAQs or internal docs. Included from Standard package and up.
Do you build voice AI that calls customers?
Yes — voice agents using Twilio + ElevenLabs + GPT/Claude that can call leads automatically (available in Premium or as a Gig Extra). Same tech I built into Markulia.
Do I get the source code?
Yes — full source code, ready to deploy anywhere. It's 100% yours.
