I Built an AI-Powered Daily LeetCode Planner Using Workflow Automation

Recently, I explored workflow automation using Kestra and ended up building a small but powerful system, an AI-powered Daily LeetCode Planner.

The goal was simple:

Stop wasting time deciding what to solve every day and automate the entire process.

What it does

Every morning, the system automatically:

Fetches coding problems from LeetCode

Selects a balanced set of Easy, Medium, and Hard questions

Sends them to an AI model for structured analysis

Generates a full study plan with patterns and hints

Emails it directly to me

Tech Stack

Kestra (workflow orchestration)

Python (data processing and logic)

Google Gemini API (AI analysis)

LeetCode GraphQL API (problem data source)

SMTP (email automation)

How the workflow works

1. Fetch problems

Pulls a list of 50 problems from LeetCode GraphQL API.

2. Select questions

A Python script:

Filters valid entries

Groups by difficulty

Randomly selects a balanced set
