About this gig
Your idea deserves more than a template.
Most AI tools give you a demo. I build the real thing - a working product your users can actually use. Backed by two production AI systems with real users.
What I have shipped:
- Multi-tenant knowledge assistant - RAG pipeline, vector search, source attribution
- Agentic AI assistant in Slack - real-time responses, policy grounding, tool-use routing
- Clearhead - AI journaling app built in 1 hour using Lovable, Supabase, Claude API
- Financial document parser with full source traceability
What I build for you: AI web apps - chat interfaces, document Q&A, smart search. Python or Node backend, React or Lovable frontend, Supabase or PostgreSQL. AI SaaS - multi-user platforms with auth, billing hooks, admin dashboards. AI chatbots - grounded in your documents, RAG pipeline, source attribution. Supports PDF, Word, Markdown, Notion, Google Drive.
Stack: Python, FastAPI, React, Next.js, Claude, OpenAI, LangChain, Supabase, pgvector, Docker.
What you get: working tested app, clean source code you own, full handoff docs, no platform lock-in.
Message me before ordering. I confirm fit and timeline first.

I build production AI systems - not demos. Two shipped platforms: a multi-tenant knowledge assistant with RAG and vector search, and an agentic AI
assistant in Slack with tool-use routing.
My stack: Python, FastAPI, Anthropic Claude, OpenAI, RAG pipelines, pgvector, MongoDB, Supabase, React, Lovable, Stripe, Docker.
I also built a financial document parser extracting structured data from PDFs using PyPDF, pdfplumber, and Claude Vision with full source traceability.
Real users. Real data. Production code.

FAQ
Which LLM should I choose - Claude or OpenAI?
Both work well. Claude tends to perform better on longer documents and nuanced reasoning. OpenAI is slightly cheaper at scale. Message me with your use case and I will give you a concrete recommendation before you order.
I am not technical. Can I manage the app after delivery?
Yes. Every delivery includes documentation and a walkthrough. Adding new content or documents is straightforward. You do not need to touch the code.
Can it handle scanned PDFs?
Yes. OCR support is included in Standard and Premium packages.
Will it hallucinate or make things up?
No. The AI only answers from the data you provide. If an answer is not in your documents or database, it says so rather than guessing. Source attribution is included on every response.
Do I own the code after delivery?
Yes, fully. No platform fees to me, no lock-in. The code is yours to host wherever you want.
Can you integrate with my existing app or website?
Yes. Message me first with details of your current stack and I will confirm fit before you order.
What if I need something not listed in the packages?
Message me. Most custom requirements can be quoted as a custom offer. I do not start work without agreeing scope first.
