signal over noise.

I’m Leon — a web and application developer working at the intersection of business informatics, UX/UI, and applied AI. I build user-centered digital products using React, Next.js, Python, APIs, and SQL, while exploring how AI workflows and knowledge systems can improve real processes.

CH 1 — FRONTEND & UX

I design and build user-centered interfaces with React and Next.js, from early Figma concepts to responsive frontend implementation.

CH 2 — AI & AUTOMATION

My applied AI work covers automation, knowledge systems, MCP servers, and modular AI platforms — always tied to a practical workflow or product need.

CH 3 — BACKEND & SYSTEMS

I connect applications to Python backends, APIs, SQL databases, and structured data, keeping the path from interface to information clear and maintainable.

when i’m not coding,
i’m making music.

Outside software, I make music with samples, tape loops, and synthesizers. The tracks emerge somewhere between improvisation and careful production, and are released under 404 Not Found Nation.

good design lives
in the details.

This portfolio was never meant to be a neutral showroom. Its interface draws on my love of analog equipment and music while reflecting how I approach projects: a strong idea, precise execution, and careful attention to detail.
