About this project

The Problem

Procurement documents, disconnected & manual

Organizations typically receive Purchase Orders (POs), Goods Receipts (GRs), and Invoices as PDFs from multiple vendors. Stored in unstructured formats and handled manually, this creates four recurring pains:

Mismatched records Invoices that don't match PO or GR line items
Slow validations Hours spent cross-checking across documents
Human errors Manual reconciliation & data entry mistakes
Delayed payments Late settlements & procurement disruptions

There's a need for an automated, scalable, and intelligent system that extracts, validates, and reconciles procurement data — using modern AI/LLM, vector search, and Delta Lake.

The Solution

An intelligent, automated reconciliation pipeline

The project automates procurement document validation by building a production-grade pipeline in Databricks using LLMs, embeddings, Delta Lake, and Unity Catalog.

End-to-end Codebase
Most "Gen AI" courses stop at a toy RAG demo. This one actually shows you how to wire LLMs, Vector Search, and Delta Lake into a pipeline that runs in production. We adapted the pattern for invoice reconciliation at our company the very next quarter.
AR
Arjun Reddy Senior Data Engineer · Banking
The three-way match logic and confidence scoring design alone were worth the price. Clear architecture, clear code.
KI
Kavya Iyer Data Engineer · SaaS
Loved seeing every piece — ingestion, extraction, embeddings, matching, orchestration — stitched together. My resume now reads very differently.
SR
Siddharth Rao Lead Data Engineer · Logistics
I needed a real LLM-on-Databricks project to put on my portfolio. This delivered exactly that — and I got interview calls within weeks.
NB
Neha Bhatt Data Engineer · E-commerce
Architecture decisions are explained, not just coded. That's rare. Now I know why we picked Vector Search over a join.

Ask a question
Who is this project course for?

Data engineers, analytics engineers, and AI practitioners who want a realistic, production-grade end-to-end project on Databricks. You'll get the most out of it if you're already comfortable with PySpark, Delta Lake, and basic Python.

Do I need prior Databricks or LLM experience?

Basic Databricks familiarity is strongly recommended — if you're new, pair this with the Databricks Zero to Hero course first. LLM experience is not required; we cover prompt engineering, model serving, and embeddings from first principles.

Will I be able to run the project myself?

Yes. The full codebase, sample PDFs, and notebooks are included. You can run the project on a Databricks trial workspace with Unity Catalog enabled. Foundation models are accessed via Databricks Model Serving (free tier available for light usage).

Can I use this project for my portfolio?

Absolutely — we encourage it. You'll learn not just how to build it, but how to talk about the architecture in interviews. We also share a one-page project summary template you can adapt for your resume.

Is this self-paced?

Yes. The course is fully pre-recorded. Watch at your own pace, pause, rewind, and revisit modules as needed. Lifetime access is included.

Is there a certificate?

Yes. Once you complete all phases and the final demo, you receive a verified GeekCoders project certificate you can share on LinkedIn in one click.
