About this gig
I build AI you can actually trust, integrated into the app you already run.
Most AI features invent answers, act without permission, and leave no record. I engineer against exactly that.
What I build
- RAG Systems: Retrieval pipelines on pgvector that answer only from your content, cite every source, and admit when they do not know instead of guessing.
- Action-Taking AI Agents: Agents that do real work inside your app behind scoped permissions, with a confirmation before anything changes, undo, and a full audit log.
- MCP Servers: Model Context Protocol servers that connect your tools and data to OpenAI, Claude or any AI client, so tasks run hands free.
- Custom Automation Pipelines: API workflows, background jobs, and Puppeteer-based scraping built on your own infrastructure and owned by your team.
How I work Retrieval and safety come first. Every build ships with an evaluation harness, cost logging, and prompt-injection handling, so you can see it works before your users do.
Built with Next.js, Node, TypeScript, Postgres, MongoDB, and Python.
Message me with what your app does and what the AI should handle, and I will tell you honestly whether I am right for it before you order.

FAQ
Will the chatbot make things up?
No. Retrieval runs first; if nothing in your content is relevant, it returns "I don't know" instead of guessing, and every answer cites its source.
Can the AI actually do things, not just chat?
Yes, agents take actions via tool calls against your backend, with permission checks on every call, a preview/confirmation step before writes, undo, and an audit log.
Can you add AI to my existing app?
Yes; that's my focus. I integrate into your current web/SaaS stack rather than forcing a rebuild.
Which models do you use?
Whatever fits your budget and privacy needs - OpenAI/Anthropic APIs or self-hostable open models (e.g., Llama). I'll recommend based on cost and data sensitivity.
How do I know it works?
I build an evaluation harness (retrieval hit-rate, answer correctness, refusal accuracy) and log token/cost per request, so quality and spend are measurable - not guesswork.
Do I own the code?
Yes. Source code and a short handoff doc are included; you're never locked to me.
Do you do voice agents / no-code automations (n8n, Zapier)?
My focus is custom-coded AI and API automation. Tell me your use case and I'll say honestly whether it's in scope or point you to the right approach.
