About this gig
Want AI inside your product, not a separate chatbot widget? I add AI features to existing React, Next.js and Node.js apps using the OpenAI or Claude API, built to work with your users, roles and data.
PACKAGES IN PLAIN WORDS
Basic: one AI feature, such as summaries, drafts or tagging, with a streaming UI and a per-user usage limit.
Standard: an assistant that answers from your docs or database, respects user roles, and has an admin button to refresh its knowledge.
Premium: an AI agent that can take actions through your API, with an action log, cost caps, fallbacks and 14 days of support.
WHAT'S INCLUDED
- Secure server-side API routes (keys never in the browser)
- Works with your existing login and permissions
- Usage limits and logging to keep costs predictable
- Clean code in your repository, which you own
NOT INCLUDED
AI provider costs (billed to you directly), model training or fine-tuning, and building a new app from scratch.
Not sure which AI feature would help most? Send me a short description of your app and your users, and I'll suggest a starting point.

FAQ
Which AI models do you use?
OpenAI or Anthropic Claude through their official APIs. I'll suggest one based on cost and quality for your use case.
Who pays for AI usage?
You do, directly to the provider, from your own API account. I add usage limits so costs stay predictable.
Can the AI see data a user shouldn't access?
It shouldn't. The feature uses your existing login and roles, and only searches data the current user is allowed to see.
Can the AI make mistakes?
Yes, any AI can. I add clear UI cues, sources where possible and fallbacks, and an agent only takes the actions you allow.
Which stacks do you support?
React or Next.js frontends with a Node.js backend, and PostgreSQL (pgvector) or Supabase for search. For other stacks, message me first.
Do you need access to my codebase?
Yes, repository access is needed to integrate properly. I only change the parts agreed in scope, and you own all the code.
