Student developer building cross-platform apps, fast Rust tools, and self-hosted systems

I like turning ambitious ideas into useful software, from polished Flutter apps to focused Rust tools and Linux infrastructure.

Featured Work

Startle

A native macOS menu-bar utility that plays a randomly selected local video on a configurable schedule. It includes safety-aware scheduling, multi-display playback, sandboxed local storage, and a dedicated emergency shortcut.

pi-calc

An arbitrary-precision command-line calculator for π, written in Rust with the Chudnovsky algorithm and GMP. It supports anything from quick checks to much larger precision runs.

About Me

I enjoy projects where product polish meets systems work: applications that behave well across platforms, tools with measurable performance, and services I can run and understand myself. I’m especially interested in Flutter, Rust, backend architecture, Linux, and practical self-hosting.

Right now, I’m:

  • Improving Startle and preparing its unsigned previews for a future signed macOS release
  • Going deeper into Rust, systems programming, and backend design
  • Running Linux-based homelab and media-server infrastructure
  • Looking for useful open-source projects to contribute to

Languages and Tools

Swift, Flutter, Dart, Rust, Kotlin, React, TypeScript, Node.js, PostgreSQL, Docker, and Linux

Let’s Build Something

I’m open to collaborating on open-source tools, cross-platform applications, Linux projects, and self-hosted software. The best way to reach me is [email protected].
