Experience

Upload Mail Service

For this project, I created an Apple mail service based in AppleScript that allows you to select emails and upload it to servers via POST requests.

UI Revamp Using Angular

Here, I designed the strategy to implement and convert an existing app into Angular that also solved the authentication and integration issues. I built the basic skeleton and kick-off components as well as the pipeline for other developers to keep working on the app and test and deliver it.

Realtor Site MVP (Minimum Viable Product)

On this project, I made a realtor single-page application MVP that allowed to list properties in either a list or in a map. Realtors could add and edit their own properties. I used React and Redux for the front-end and Express.js for the back-end as an API. I implemented Firebase for the server structure, using cloud functions and a Firebase real-time database.

Calorie log MVP (Minimum Viable Product)

Here, I made a calorie log single-page application MVP that allowed users to log their food intake giving the calories or leave it to an API to try to figure out the calories. You could set up your calorie goal in order to see if you were under or above it.

I used React and Redux for the front-end and Express.js for the back-end as an API. I used Firebase for the server structure by using cloud functions and a Firebase real-time database.

Home Screen Dashboard

I improved and maintained a home screen dashboard built in Django. The user sessions were integrated with the rest of the system built in 4D.

Cloud Formation Schema Generator

I maintained and enhanced a schema generator that allows users to create JSON entities. These can then be used by cloud formation in order to create production-like stacks in order to implement JSON data and configuration testing in isolated environments. This was built using Flask.

AWS Server Management App

This is a Vue.js and Electron desktop that allows a user to list AWS servers based on personal keys and group it by different tags. Based on the type of server, it also allows you to connect to the server either by SSH or RDP. It also has useful information and links to documentation.
