You will get Custom RAG System with GPT-4o for Private AI Search & Knowledge Retrieval
Top Rated
Project details
Unlock the power of your internal knowledge with a fully customized RAG (Retrieval-Augmented Generation) system built on GPT-4o, designed to deliver accurate, private, and context-aware answers from your documents, databases, and internal resources.
Unlike generic chatbots, this solution is engineered for zero-hallucination performance, advanced semantic search, and robust data privacy, tailored specifically for your organization’s workflows. I design everything end-to-end, including data preprocessing, chunking strategy, vector database setup, embedding optimization, pipeline engineering, and GPT-4o integration.
Whether you need a private company knowledge assistant, an AI customer support engine, a research search tool, or an automated Q&A system, your RAG pipeline will be scalable, secure, and deployment-ready. You’ll receive full documentation and support for seamless adoption.

That's where I come in. I build AI agents and automation systems that take it off their plate, so you can focus on growing the business, not running it day to day.
If your team is stuck doing manual research, chasing leads, screening resumes or entering data by hand, that's exactly the kind of work I replace with custom AI agents and automations, built to run reliably, not just impress in a demo.
I have worked with businesses, agencies and individuals across education, healthcare, ecommerce, real estate and professional services and I customize every build to the actual bottleneck slowing your team down, whether that's a research heavy process, a lead pipeline or content that needs to go out consistently without someone doing it manually.
🚀 For example I built:
🎯 AI Outreach Engine - Finds qualified prospects, researches each one and sends personalized LinkedIn and email outreach at scale, then manages replies and new connections without manual follow-up.
📋 HR Assistant Agent - Reads incoming resumes from email, evaluates candidates against job criteria with AI, logs results to a sheet and automatically schedules interviews on the calendar.
🏘️ Property Inventory Enrichment Agent - Uses AI image recognition and web research to automatically identify and enrich real estate/product inventory data from photos, saving hours of manual data entry.
💬 Lead Capture Chatbot with Handoff & Guardrails - Qualifies inbound leads 24/7, logs them automatically, and escalates to a human team member via Slack/email exactly when needed.
🎙️ Voice AI Lead Pipeline – Captures leads from web forms and voice AI (VAPI) call transcripts, validates and structures the data, then sends personalized AI-composed follow-up emails automatically.
🔍 LinkedIn & Indeed Job Scraper – Automatically pulls and merges job listings from two platforms based on user criteria, saving the results for easy comparison.
🛠️ Tools & Tech I Work With:
n8n • MakeDotcom • Zapier • OpenAI (GPT-4) • Claude • VAPI (Voice AI) • LangChain • Python • FastAPI • Google Workspace • Airtable • Slack • REST APIs & Webhooks • Postgres • GoHighLevel (GHL) • CRM Integrations (HubSpot, Salesforce)
✅ What this means for your project:
🤖 Your manual workflows - outreach, lead qualification, data entry, content publishing, become autonomous agents that run without you managing them.
🔗 Your existing tools (CRM, ecommerce platform, Google Workspace, Slack, databases) get connected instead of operating in silos.
🛠️ If your project needs more than a no-code workflow, I can build a full custom backend (Python, FastAPI) instead of forcing a fit.
🏗️ You get a production ready system, not a fragile demo, built to keep running after I'm gone
📝 You get clean, documented builds and clear communication, so you always know what's happening and why.
Whether you're a small agency looking to scale delivery without adding headcount, a business wanting to automate lead capture and follow-ups, a content team needing to publish consistently without manual work or a founder with a repetitive workflow to automate, I scope before I build. You get a clear architecture doc, weekly demos and same day responses on weekdays.
📩 If a process is slowing your team down or you're not sure what's even possible with AI right now, send me your scope and I'll tell you honestly whether I'm the right fit.
