I like building things
—from scalable backend systems to small experimental tools

• Backend: Spring Boot, JPA, Redis
• Frontend: Vue 3, Nuxt, TypeScript
• Infra: AWS, Docker, CloudFront, Vercel
• Exploring: AI / LLM / Developer Tools

• MyTools
  → A collection of developer tools I actually use
  → Built to replace scattered, ad-heavy online tools
  → No ads, no tracking, no server-side processing
  → Everything runs locally in your browser
  → https://tools.jongwoo.me

• cloudip (beta)
  → CLI tool to detect cloud providers from IP addresses
  → Useful for debugging infrastructure and identifying traffic origins
  → Supports batch input & multiple output formats (table, JSON)
