Louis the cat

Hewwo, I'm Louis Johnson

The cutest cat you will ever meet

I build systems, tools, and applications that prioritize performance, reliability, and thoughtful engineering — constantly learning and refining how software should work and feel.

About Me

I'm a high school student from Vietnam who loves building software and understanding how things work beneath the surface. I spend most of my time designing systems, experimenting with ideas, and turning complex problems into clean, reliable code — learning a little more with every project.

Systems Design

I enjoy breaking software into clear, modular systems — making complex ideas feel simple, predictable, and easy to maintain.

Tooling & Frameworks

I build reusable tools and small frameworks that improve developer experience and make future iteration easier.

Performance & Reliability

I naturally explore bottlenecks and edge cases, focusing on software that stays fast and stable under real-world use.

Learning by Building

I learn best through experimentation and shipping projects — understanding why things work, not just how.

How I think about software

I enjoy breaking complex problems into understandable systems. Rather than chasing trends, I focus on building software that stays predictable, maintainable, and easy to reason about long after it ships.
