Work Experience

Full-stack Unity3D AR Developer

2022 - PRESENT
Henry Schein
  • Worked on developing a mobile app using augmented reality (AR) technology. The main challenge was to use the still young technology for facial recognition and make it compatible with all devices.
  • Improved my knowledge of Unity's Cloud Build and created a CI to automatically publish the build on the Apple and Android stores.
Technologies: Unity, Augmented Reality (AR), Unity3D, Apps, iOS, Android, AR Foundation

Full-stack Developer

Machine Learning Engineer

2021 - 2022
  • Implemented a banking and insurance data classification system to make predictions of interesting products to the customer.
  • Developed different models that achieved accuracy exceeding 90%.
  • Designed the classification system that adapts to the incoming data by preparing it correctly according to the type of data received and modifying the network structure—all without requiring human intervention.
Technologies: APIs, Algorithms, Machine Learning, Python 3, TensorFlow

Unity3D Teacher

2020 - 2021
  • Taught a course that covered the main mechanics of Unity up to the programming of complex inventory management systems or the creation and modification of the Unity tools.
  • Instructed students to make two video games following the game designers' specifications by the end of the course.
  • Gave technical lessons and prepared lesson material, which I found to be a beautiful and interesting experience.
Technologies: Unity, 3D Math, Conference Speaking

Software Analyst

Unity Solar System | Newton Simulator

Developed a rigid body simulator using Newton's equations. The simulation uses the GPU to process all interactions. The performance is around 60FPS for 4M bodies and 0GC with an RTX 2080. I applied the principle of divide and conquer to develop it, and I also used the API provided by Unity to communicate with the GPU. The simulation code is entirely written in HLSL.

I spent eight hours on development.

Cloud Nodes

This is a project that I developed in my spare time. I got the idea from a JavaScript library to animate the website background and wanted to see how it could come out on Unity. I spent 30 minutes developing this project.

Azure DevOps

The job involves obtaining certification in Azure DevOps, building and configuring projects within the platform, and approving and overseeing the deployment of projects to ensure proper functionality and adherence to project specifications. The role requires expertise in using Azure DevOps to manage projects and ensure successful deployment.
