About

Hi, I'm InstaZDLL.

I'm a software developer building performant tools and open source software. This portfolio gathers 10 projects across many domains: web SaaS, desktop applications, terminal clients, and hardened infrastructure stacks.

I like to learn, code and experiment. Some of my projects are commercial SaaS like AtlasFlow (enterprise Gantt) or Helvetseo (Swiss SEO audit). Others are pure open source: WaveFlow (local music player), OmniGet (universal downloader), plume-tui and tui-kart64 for the terminal, wp-splendid for self-hosted WordPress.

Each project tries to do one thing well, with a focus on performance, accessibility, and a clean developer experience. Stack varies by project — TypeScript and React for the web, Python for terminal apps, Bun and PostgreSQL for the heavier SaaS, GTK4 for native Linux desktop, Docker for infra.

Lots of ideas, not yet all the skills to bring them to life… but I'm getting there. Feedback and contributions welcome on GitHub.
