안지율 · Stony Brook, New York

I consider myself someone with a strong strength in UX. The goal is to stand at the forefront of a specific field. The areas I mainly developed were mostly spreadsheets, paper formatting, or tasks that replaced procedures known only to one person in the team.

I placed a lot of them targeting places without a pool of developers. I carried out a lot of work to realize DX by handling everything from schema design to screens and deployment. It also includes sitting next to the person who will actually use it and seeing how the day’s work unfolds;

    A bachelor’s platform for SBU & SUNYK students. The service applies only to the @stonybrook.edu domain. Reached 100 subscribers on the first 20 days; currently version v.3.7.1

    Provides credit visualization and simulation, curriculum pathways, my timetable overlaid on friends’ timetables, anonymous course reviews, and nearby cafes, among other things; the first version was refreshed with Falling and migrated to Supabase Realtime

    In October 2025, we started as a joint project by the Decompiler × LAMBDA club, and after taking on idea generation and project leadership, we began with a team of 12 people. It broke off as an independent project in January 2026, and it is still ongoing now

Tools

Mostly TypeScript, React, Postgres. When I need to move quickly, Supabase is the one. Before that, I’d been using PHP for about two years; Tailwind is also designed with speed (and because AI likes it..) as a strength.
