Frequently Asked Questions

A proof-of-concept (PoC) or a basic n8n automation workflow typically takes 2–4 weeks. Full-scale RAG implementations or custom AI agents generally require 6–10 weeks depending on data complexity.

Absolutely. I prioritize privacy-first architectures, ensuring that sensitive data is handled via secure APIs or local vector stores, and is never used to train public models without your explicit consent.

Yes. I specialize in building "AI layers" for existing Python, Laravel, Express, or React applications, allowing you to add intelligent features without a complete rebuild.

AI models and APIs evolve rapidly. I offer specialized AI maintenance packages that include prompt tuning, model updates, and performance monitoring to ensure your agents stay accurate over time.
