Full-Stack Developer

I enjoy taking a complex system and turning it into an accessible website that helps users understand what matters, how it connects, and what to do next.

ABOUT

I turn confusing systems into clear, useful interfaces.

Hi, I'm Sadie. I build tools that make the world feel a little less overwhelming, whether that means figuring out when to leave for the airport or seeing how one date can look different across cultures.

I got into web development because I believe access to understanding is its own form of equity. I'm drawn to geography, systems thinking, and the quiet satisfaction of turning something complicated into something people can actually use.

  • Making confusing things easier to understand
  • Designing around how people actually use the web
  • Building projects that feel useful, not just finished

Tools I work with

  • HTML
  • CSS
  • JavaScript
  • Tailwind CSS

Projects

Users enter trip details and get a clearer departure plan based on travel timing, airport friction, and the parts of flying that are easy to underestimate.

  • Decision support
Calendar Converter interface showing alternate calendar date results

Calendar Converter

LIVE

A date conversion tool that translates Gregorian dates into alternate calendar systems for broader cultural context.

The project turns a familiar date into Hijri, Jalali, and other formats so users can see how time is represented across different traditions.
