Level 2
About this gig
Have an idea for an AI-powered SaaS product, or want to add serious AI capability to a new build? I specialize in building full-stack applications powered by OpenAI's GPT-4 and GPT-4.5 models, from a single AI feature to a complete SaaS platform.
Using OpenAI's APIs, I build the frontend, backend, authentication, and admin systems needed to launch a real AI-powered product, not just a bolted-on integration.
What I Can Build
AI chatbots & conversational agents with memory
Full AI SaaS platforms with user auth & admin panel
Content generation tools (blogs, captions, emails)
AI search & Q&A tools
Voice features: text-to-speech & speech-to-text (Whisper)
AI image generation (DALL-E)
Custom AI workflows & automation for SaaS or education
Why Work With Me
3+ years AI + full-stack development experience
End-to-end builds: frontend, backend, database, and auth
Clean, scalable, and secure architecture
Firebase or MongoDB backend
Modern UI with React, Next.js & Tailwind CSS
Clear and responsive communication
Let's Build Something Smart Together
Message me before ordering so we can discuss your product idea, AI features, and project scope for a smooth, successful build.
