Gig Summary
About this gig
Need AI inside your product, not just a ChatGPT tab open next to it?
I integrate OpenAI, Claude and other AI APIs directly into the software you already run websites, web apps, backends, internal tools and automation workflows.
What I can build for you:
- OpenAI / ChatGPT / Claude API integrations.
- Vibe coded MVPs
- AI chatbots and assistants embedded in your site or app
- SaaS web and mobile apps through AI.
- AI appointment and booking system
- Custom AI scripts and automations for repetitive business tasks
- Third-party integrations: Google Sheets, Calendar, Airtable, Slack, WhatsApp, CRMs
How I work:
I write production code, not demos. That means proper error handling, API key security, rate limiting and retry logic, so your integration doesn't break the first week it's live. You get clean, documented code you or your developer can maintain.
Why me:
7+ years building software for international clients, with the last several focused entirely on AI systems voice agents, WhatsApp automation and AI SaaS products in production use today.
