Case Studies

Salon Management System

Vitoria’s Beauty

Business Website & Admin System

Problem:

A beauty business with three locations needed to consolidate operations, service details, pricing, team listings, and gallery displays while enabling non-technical staff to manage content dynamically.

Solution:

Built a mobile-first, high-performance business website integrated with custom secure administration tools.

Rafael's Contribution:

Designed and implemented the front-end layout, responsive pricing tables, location guides, and a password-protected admin dashboard. Set up state synchronization with Supabase, user authentication, and media upload pathways.

Result:

Enabled salon managers to update service pricing and gallery pictures in real time, bypassing manual code changes.

Full-Stack Portfolio & Management

Cláudia Makeup

Full-Stack Business Website & Admin Panel

Problem:

A freelance makeup artist required an editorial-grade professional website to showcase her portfolio with filtering options, present client testimonials, and capture structured booking requests.

Solution:

Designed and deployed a responsive business website with an integrated booking-request pipeline and a private administration portal.

Rafael's Contribution:

Created dynamic portfolio filtering, structured booking forms and a secure Supabase-backed dashboard for managing requests and portfolio images.

Result:

Automated booking request logging and portfolio gallery updates, removing manual workflow friction.

Browser Extension / Workflow Automation

ShopKit AI

Chrome Extension for Product Automation

Problem:

E-commerce managers spent an average of 15 minutes manually copy-pasting and formatting product details across 15+ complex ShopKit fields for each new product.

Solution:

Engineered a Manifest V3 JavaScript browser extension that automatically parses product titles and queries generative APIs to populate fields instantly.

Rafael's Contribution:

Wrote the injection scripts, automated content scraping pipelines, structured OpenAI API integration calls, and implemented local configurations saving using the Chrome Storage API while preserving custom manual field edits.

Result:

Reduced the product creation workflow from approximately 15 minutes to approximately 45 seconds per item.
