Master Inventory Logic with Python & AWS: Build a Serverless Order Management System (Python, AWS Lambda, DynamoDB)

What you’ll learn
– Design and Implement Business Logic: Master core inventory concepts such as "Logical Inventory" vs. "Available Inventory" (ATP), and implement "Reorder Point".
– Build a Full Serverless API: Create a scalable REST API using AWS Lambda, API Gateway, and Amazon DynamoDB from scratch.
– Object-Oriented Programming in Practice: Learn how to design robust Python classes (InventoryManager) to encapsulate complex business rules.
– Test-Driven Development (TDD) Approach: Perform comprehensive testing, ranging from Python Unit Tests for business logic to Integration Tests using Postman.
Requirements
– AWS Account: A valid AWS account is required (The Free Tier is sufficient for this course).
– No Supply Chain Experience Needed: We will explain all necessary logistics and inventory management concepts from the ground up.
– A computer with internet access.

Description
"I know how to use AWS services, but I don’t know how to combine them into ausablebusiness system.""What kind of calculation logic do professionals actually use behind the scenes of an inventory management system?"

If you have ever asked yourself these questions, this course is designed for you.

Why this course?Many tutorials teach tools, but few teachDomain Knowledge. In this course, we bridge that gap. You will learn the essential logic used in the logistics industry, such as:

The critical difference between"Logical Inventory"and"Allocated Inventory"(Available to Promise).

How to calculateSafety StockandReorder Points (ROP)to prevent stockouts.

You will implement these concepts usingPython Classes, ensuring your code is clean, reusable, and robust. Then, you will deploy this logic onto a modernServerless ArchitectureusingAWS Lambda,Amazon DynamoDB, andAPI Gateway.

【Course Agenda】

Section 1: Introduction & System Design

Why inventory management matters (preventing Opportunity Loss & Overstock).

Designing a Serverless Architecture (API Gateway + Lambda + DynamoDB).

[Hands-on] DynamoDB Table Design & Environment Setup.

Section 2: [Unit Test 1] Inventory Movement Logic

What is "Logical Inventory"?

Creating the InventoryManager class in Python.

[Hands-on] Unit testing for Inbound (Receiving) and Outbound (Shipping) using Lambda test events.

Section 3: [Unit Test 2] Order & Allocation Logic

The concept of "Available Inventory" (ATP).

[Hands-on] Implementing "Order Allocation" logic and testing for "Insufficient Stock" errors.

Section 4: [Unit Test 3] Reorder Point (ROP) Management

Calculation methods for Lead Time and Safety Stock.

[Hands-on] Implementing auto-calculation of ROP and Alerting triggers.

Section 5: [Integration Test] Scenario Testing with API Gateway

Building the REST API with Lambda Proxy Integration.

Connecting to DynamoDB using Boto3.

[Hands-on] Executing a full business scenario (Order -> Ship -> Alert) usingPostman.

OLTP (Online Transaction Processing) vs. OLAP (Online Analytical Processing).
[Hands-on] Implementing an automatic inventory history tracking system usingDynamoDB Streams.

【About the Instructor: Maruchin Tech】

Who this course is for:
– Python Developers who want to step up from writing scripts to building real-world serverless applications on AWS.
– Cloud Engineers interested in "Domain-Driven Design" and learning how to implement actual business logic behind the infrastructure.
– Logistics & Supply Chain Professionals who want to understand the technical "black box" behind Warehouse Management Systems (WMS) and ERPs.
– Students & Beginners looking for a practical portfolio project that goes beyond simple "Hello World" tutorials.
