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.
Managed AWS services (Cognito, AppSync, API Gateway, Lambda, S3, DynamoDB) for applications on the AWS Amplify stack. Collaborated on moving from fixed forms to dynamic Form.io forms, deployed a self-hosted Form.io Enterprise instance on AWS, then migrated to the open-source core to cut recurring costs while keeping the apps working. Developed and helped design a SaaS platform organizations use to submit and review homeownership applications.
Worked as a freelance mobile developer in charge of the UI development of a prototype for a services mobile app
Deployed web applications to Linux servers for professors and students in the School of Engineering and Architecture. Designed, developed, and maintained the frontend of a MERN capstone project (Android and web): upgraded the Android app to a current SDK, modernized the web dependencies, revamped the UI, and fixed bugs for production. Deployed and configured a GitLab instance for CIDES (Centro de Investigacion y Desarrollo de Software, or in English the Software Research and Development Center).
Developed, designed, and maintained a web application for managing dosimeters as part of a university service project.
