About LeanJ & Me

Hi, I’m Yusuf Aslan, a software developer passionate about building lightweight, high-performance tools for Java developers.

LeanJ is a minimalist Java profiler designed to measure application performance with near-zero overhead. It’s built for production environments and comes with AI-ready features, letting you convert profiling data into structured prompts for ChatGPT, Cursor, or IntelliJ AI.

I love creating tools that save developers time, provide actionable insights, and integrate seamlessly into existing workflows.
