I will build ai powered web applications using openai and groq api


About this gig
Want to add AI capabilities to your product, or build an AI-powered app from scratch? I build production-ready AI web applications real systems running in production, not demo prototypes.
I've built and deployed WhatAutomater, a live AI-powered WhatsApp automation SaaS with LLM-driven auto-replies, AI analytics dashboards, and voice transcription currently serving real users in production.
WHAT I BUILD:
AI chatbots (OpenAI, Groq LLM integration)
AI-powered SaaS platforms & dashboards
Voice-to-text & transcription tools (Whisper API)
Custom AI workflows & automation
RAG-based apps & AI analytics
Full-stack apps (React + Node.js + Supabase/MongoDB)
WHY WORK WITH ME:
- Real production experience not just tutorials
- Fast, cost-efficient LLM integration (Groq for speed, OpenAI for capability)
- Clean, scalable, documented code
- Certified in Generative AI (IBM) and AI Fundamentals (Google)
Message me your idea before ordering I'll tell you honestly what's possible, what it'll cost, and how long it'll take.

FAQ
Q: Which AI model do you use — OpenAI or open-source?
A: I work with OpenAI, Groq (Llama models), and can integrate any LLM API based on your budget and speed needs.
Q: Can you connect the AI to my existing app/database?
A: Yes, I can integrate AI features into an existing codebase or build from scratch.
Q: Is the AI response speed fast?
A: Yes — I use Groq for near-instant responses when speed matters, OpenAI when you need maximum capability.
Q: Do you handle API costs?
A: You'll need your own API key (OpenAI/Groq) — I'll help you estimate usage costs before we start.
