Joaquin Carretero - Personal Portfolio

About me

Hi, I'm Joaquin (or Quino to my friends)! I'm a software engineer who loves mixing automation with emerging tech like AR/VR and 3D printing. For example, I'm currently developing an augmented reality app for a virtual museum exhibit. I also design 3D printed phone cases and write programs that automate stock trading for fun.

Throughout my career, I've looked for roles where I can make an impact. As a Software Engineer Lead @ Meta, I led automation initiatives that improved hardware testing and streamlined internal systems. I find it fulfilling to create solutions that benefit the organization. I'm passionate about using my skills to build innovative tech and help others. In my free time, you can often find me tinkering on my latest automation or 3D printing project! I love bringing ideas to life through code.

What i'm doing

Building Augmented Reality Apps

Currently using Flutter and ARKit to build an Augmented Reality Museum App that encourages art lovers to use technology in public spaces and experience art in new ways. My startup has been submitted to YCombinator.
Automating the Stock Market

Using Python, Selenium, and several APIs, I created a framework that uses the famous Black Scholes algorith and adds Machine Learning training to predict the price of a call the next morning when the market opens.
Exam Ai Platform

I am making a platform that will allow professors to grade students hand-written exams/quizzes instantly by using Computer Vision libraries to translate handwriting into text, and feeding such text to an API based GPT4-Turbo model that will grade submissions based on the professor's criteria. Such platform will have data analytics to help the professor know where students lacked the most.
Photography

As a Professional Photographer, I shoot with a Sony A7IV. My lens of choice is a Sigma 50mm f/1.4 which i use mostly for portraits! At Meta, I worked in the Camera Research organization making proprietary imaging algorithms to optimize the best Field of View for a small sized camera that later on was implemented in the 2023 RayBan Stories.
