Build a High-Quality AI Interface – Frontend, Backend, API Integrations

Job ID: 39208608

Budget: $400 – $1,100 USD

Hello,
I’m building a high-end AI-based application that integrates multiple LLMs (Large Language Models) into one unified interface. The project is designed for a global audience and focuses on delivering an elegant, highly interactive user experience.

I’m currently looking for a freelancer or small team with one or more of the following skills:
• Frontend development (React.js / Next.js)
• Backend development (Node.js or Python)
• API integration (OpenAI, Claude, DeepSeek, etc.)
• Database experience (Supabase preferred)
• TTS/STT implementation (text-to-speech, speech-to-text)
• Optional: UI/UX design skills

Important notes:
• This is not a basic chat app. I’m looking for strong, clean architecture and production-level execution.
• The core idea will only be disclosed after agreement or NDA (if required).
• Preference for those with past AI or SaaS work.
• Clear communication, speed, and professionalism are essential.

If you’re interested, please send:
• Your portfolio or relevant past work
• Your core strengths and tools you work with
• Your availability in the next few weeks

Looking forward to collaborating with someone great.
