Mid-level Software Developer

2018 - 2022
Intelie
  • Created the 3D model in the blender of an overseas oil rig and implemented it using Three.js. The model included the oil rig and the different ground levels. It was also animated to simulate the drilling process and receive live data.
  • Modeled and implemented the 3D for a food factory that allowed managers to have an overview of the operations and keep track of workers in real time. This widget was a key factor in landing the contract on that client.
  • Developed an app that helps food factory workers and managers track and assess the quality of the produced food. Operators can create quality analyses, and managers can see dashboards with information compiled from every production line.
  • Delivered a set of beautiful dashboards with 3D models and animations in a proof of concept that led us to impress the clients, engage the internal users, and close the deal.
  • Served as a member of the diversity committee responsible for creating the company's code standards committee and the web accessibility committee.

Full-stack Bike Rental App

https://rent-a-bike.netlify.app/#/
This is a MERN stack (Mongo, Express, React, and Node.js) bike rental web app conceived with a mobile-first approach.

It includes two user roles, manager and user, who can create an account and log in.

Each bike has the following information in the profile—model, color, location, rating, and a checkbox indicating if the bike is available for rental or not.

Managers can:
• Create, read, edit, and delete bikes.
• Create, read, edit, and delete users and managers.
• See all the users who reserved a bike and when.
• See all the bikes reserved by a user and the time of reservation.

Users can:
• See a list of all available bikes for some specific dates.
• Filter by model, color, location, or rate averages.
• Reserve a bike for a specific period of time.
• Rate the bikes with a score of 1-5.
• Cancel a reservation.

The front end is hosted with Netlify and the back end with Heroku.

You can get the user experience creating your profile or using:
• User login: test@gmail.com
• User password: 12345678

You can get the manager experience using the following information:
• Manager login: manager@gmail.com
• Manager password: 12345678

A House Plant Finder

https://renemennab.github.io/green-friend/
This is a prototype of a responsive web app that helps users find the best plant to have given the condition of their home. After answering three questions, it returns a grid of plants that fit those conditions. It was made to practice following designs provided to me on Figma and showcase the front-end fundamentals. With that in mind, it was developed using only HTML 5, CSS, and Vanilla JS without libraries or frameworks.

Quality Assurance App

I led a team of eight people in creating an app that helps food factory workers and managers track and assess the quality of the produced food. The app allows operators to generate quality analyses and managers to see dashboards with information compiled from every production line.

Food Donation App

A social network app that allows restaurants to get in touch with nonprofit organizations near them to help them distribute excess food to people in need before it expires. Users can see the location of the nonprofits on a map and their information in their registered profiles. They can then schedule meetings and deliveries.
