l/ lean

I make practical software for the web and iPhone.

I turn ideas into software people actually use — developer tools, privacy-minded infrastructure, and native apps.

📐 About & Approach

My work sits where product thinking meets robust systems engineering. I build web utilities, native iPhone applications, and security-minded infrastructure. I care deeply about speed, low resource footprints, and the quiet details that make software dependable long after the demo.

  • Terminal & Systems: Dependency-free Go CLIs and single-binary tools with minimal attack surfaces.
  • Native iOS: Local-first SwiftUI & SpriteKit apps designed for responsiveness, zero tracking, and offline privacy.
  • Open Web: Fast, accessible, and standards-compliant web platforms built with React, Next.js, and TypeScript.
