About me

My name is José Luis. I build browser extensions and small web tools that people actually use. Most of my work is front-end: React, Next.js, and Chrome extensions. This site is the public home for those products, not a placeholder landing page.

Products

• Fansly Downloader — a Chrome extension to back up Fansly videos and photos you already can view.
• Fansly Manager — clips, posting templates, consulting, and automation for creator profiles.
• Telegram Downloader — a browser extension to save media from Telegram channels and groups.

Technical skills

• React.js (TypeScript and JSDoc)
• Next.js (TypeScript and JSDoc)
• Nest.js and Express.js
• Relational databases: Microsoft SQL Server, MySQL, PostgreSQL
• NoSQL: MongoDB and Firebase
• Browser extensions with Plasmo
• Git and GitHub
