      • Automated Engagement: Like photos and follow users with customizable rules to mimic organic interaction.

      • Follower Insights: Instantly see which users don’t follow you back, helping you refine your network.

      Voice Biometric Auth System

      Alohomora is a system idealized for the management of gatehouses in condominiums and buildings that aims to solve problems of cost with gatehouses and provide autonomy to residents.

      The system has a voice biometrics tool, making the resident's voice become their own key. Such functionality makes the use of passwords secondary.

      Developed a voice biometric authentication system using MFCC and FastDTW.

    • Featured Project

      Build a Spotify Connected App

      Having struggled with understanding how the Spotify OAuth flow works, I made the course I wish I could have had.

      Unlike tutorials that only cover a few concepts and leave you with half-baked GitHub repositories, this course covers everything from explaining the principles of REST APIs to implementing Spotify's OAuth flow and fetching API data in a React app. By the end of the course, you’ll have an app deployed to the internet you can add to your portfolio.
