Custom GPT & RAG Assistant on Your Data

$40/hr Starting at $800

Generic AI does not know your business. It guesses, and guessing costs you trust. I build custom AI assistants that answer from your own documents, policies, and data — so every reply is grounded in what is actually true for you.


I am a Principal Software Engineer (Engineer of the Year 2023) with 6+ years building production systems at scale. I hold a Machine Learning Specialization from DeepLearning.AI and I use proper retrieval (RAG — Retrieval-Augmented Generation) so your assistant cites your material instead of making things up. I have shipped production systems handling millions of requests that stay accurate under real load.


What you get:

- An assistant grounded on your docs, PDFs, website content, or knowledge base

- Accurate, source-backed answers with sensible fallbacks ("I am not sure, let me connect you to the team")

- Delivered as a web widget, internal team tool, Slack app, or shareable custom GPT

- Guardrails for topics it should escalate to a human

- Documentation and a retraining guide


Demo: https://summit-trails-assistant.vercel.app (fictional business — shows cited answers in action)


Background: I re-architected a multi-OTA booking engine (GetYourGuide, Viator, Airbnb, Rezdy) handling millions of requests. The same production discipline applies here — your assistant should be dependable, not impressive in a demo and wrong in production.


Share what it needs to know and I will scope the right approach before we start. Milestone-based via SafePay.
