About

Hi, I'm Ki Hyun Park.

I'm a software developer based in Seoul, Korea. I currently work at Penta Systems Technology, primarily building desktop and mobile apps with Flutter + Riverpod. I'm also interested in native plugin development with Go and Rust, and cross-platform development for Windows and macOS.

About This Blog

TechLog is a technical blog I built to organize and share what I learn during development. It's built with Next.js, Supabase, and Vercel. The main topics I cover include:

• Flutter app development and package creation
• Rust/Go programming and native plugins
• AI tools (Claude Code, MCP, etc.)
• Development environment setup and practical tips

Open Source

I maintain and publish 21 Flutter/Dart open-source packages on pub.dev. Some highlights include:

• flutter_alone - Prevents duplicate app execution on desktop (Windows/macOS)
• x509_cert_store - X.509 certificate store with macOS Keychain integration
• flutter_bin - Extracts metadata from desktop binaries
• macos_window_toolkit - macOS window info and permission management
• just_color_picker - HSV color picker widget

Tech Stack

• Languages: Dart, Go, Rust, TypeScript, Python
