FAQ
What do I need to provide to start?
Share your project requirements, preferred stack (Next.js, Laravel, Python), design wireframes, and API keys for OpenAI/Claude or vector databases.
How do you prevent AI request timeouts?
I build background worker queues (Redis/Laravel Horizon) to handle long-running LLM tasks asynchronously without freezing the UI.
Who covers LLM API and vector DB costs?
You will use your own API accounts (OpenAI, Pinecone, Vercel). I optimize prompts and implement caching to minimize your token usage.
Can you add AI to my existing application?
Yes, I integrate custom RAG pipelines, AI agents, and LLM endpoints directly into existing Next.js, Node, Python, or Laravel codebases.
Do I get full source code ownership?
Yes, you receive complete source code, deployment scripts, and documentation following clean architecture and security standards.
