Hello, I'm

Diego Quinteros

Computer systems engineering student, frontend developer, gamer and cartoon lover (western and anime) based in El Salvador. I fell in love with programming when I started technical high school and from then on I've been looking to expand my knowledge to become a better programmer.

Tech stack

Here is a list of the technologies I use the most

Experience

Improved UX for gated premium features by centralizing feature-gating logic and redesigning those flows so users get clear next steps (upgrade, accept an invitation, or switch workspace). Implemented UI and business rules for two building-regulation systems (U.S. and international). Contributed to an early user portal dashboard with an interactive map, table views, and filters over obfuscated user data. Aligned PDF export styling and content with the web UI. Maintained a legacy SaaS app alongside the current version (production bugs and UI updates for users who had not migrated). Incrementally upgraded React, Next.js, Prisma, Clerk, and MUI one library at a time to limit regressions.
