I will build ai applications, integrations and chatbots
Miguel L
About this gig
I build practical AI-powered tools for your website or business, chatbots, integrations, and automations that solve a real problem.
My background: I am a full-stack developer who has shipped real production software, including a finance app connecting to real bank accounts via Open Banking, and a real-time app with live sync across multiple users. That same foundation is what makes a chatbot or integration actually reliable, not just a flashy demo.
What I offer:
Custom AI chatbots (GPT or Claude) trained on your business info, not generic answers
Integrations connecting your chatbot to tools you already use (email, CRM, spreadsheets, Zapier)
Clean, well-commented code you can maintain or hand to another developer
What this is not: training or fine-tuning a model from scratch, a different discipline. This is about applying existing AI models well, which covers most real business use cases.
I will need a description of what you want it to do, and any info it should know about your business.
Turnaround: 7-18 days depending on package. Revisions: 1-3 depending on package.
Message me before ordering if unsure which package fits, or for a custom request.

FAQ
What information do you need from me to get started?
A description of what you want the chatbot or integration to do, plus any documents or info (FAQs, product details) it should know about your business. I will confirm scope before starting.
Which AI models do you use?
Mainly GPT (OpenAI) and Claude (Anthropic), the two most capable and widely used models for business chatbots. I will recommend the best fit for your specific use case.
Do you fine-tune AI models?
This gig is about integrating and customizing existing models (GPT/Claude) with your business info, not training a model from scratch. That covers most real business needs, often better and faster.
Is my data safe and private?
Yes. Your information is only used to power your chatbot responses. I do not share, sell, or reuse your business data for other projects.
Can you connect the chatbot to tools I already use?
Yes, on Standard and Premium, common integrations include email, CRMs, spreadsheets, and Zapier. Message me first if you need something specific, to confirm it is possible.
