About this gig

Turn your documents, FAQs, or website into an AI assistant that

actually knows your business.


I build custom RAG (Retrieval-Augmented Generation) chatbots that read

your PDFs, docs, or website content and answer questions accurately

no hallucinated nonsense, no generic ChatGPT wrapper.


What you get:

Chatbot trained on YOUR content (docs, PDFs, website, knowledge base)

Accurate answers with source grounding (reduces hallucinations)

Simple web widget or API endpoint embed anywhere

Works in English and Russian

Clean, documented, production-style code (not a throwaway script)


Why work with me:

I build production RAG systems with FastAPI, LangChain, pgvector, and

Docker hybrid retrieval, reranking, and evaluation, not just a basic

demo. I've shipped a full RAG chatbot API with CI and OCR support for

scanned documents.


Common use cases:

- Customer support bot trained on your help center

- Internal knowledge assistant for your team's documents

- Website chatbot that answers from your product docs

- Research/legal document Q&A assistant


Send me your documents/website and what you want the bot to do

I'll confirm scope before you order.

Hi, I’m Alex, a backend developer focused on clean REST APIs, database design, authentication, and third-party integrations. I build reliable backends with Python, FastAPI, Flask, PostgreSQL, SQLite, Docker, JWT authentication, Stripe, Twilio, GitHub APIs, and clear documentation. My goal is to create backend systems that are simple to use, easy to maintain, and ready for real projects. I care about readable code, clear communication, and practical solutions. Message me before ordering so I can understand your project and recommend the best package.
