A mobile app that allowed workers and supporters from roads to log accidents. The app captured and stored metadata, pictures, videos, and audio about the accident and sent them to a central operations center.

The main challenge in this project was the data exchange. Since the workers were on the road, driving and checking the road itself, their internet connection was very poor, so a single picture could take forever to upload.

We solved this by prioritizing the content and later splitting it into small chunks. I was in charge of the mobile app and some parts of the back end.

This is a solution for hospitals that allow them to live-stream newborn videos to relatives and friends of the parents.

The system works with IP-cameras and the player version works on web and smart TVs.

This is an interactive learning object that aims to help to teach programming visually. This learning object allows the user to code without typing statements (the user just selects which statement to use and fill some fields—like "how many repetitions" or "read a number").

The main challenge in this project was simulating a sync algorithm using an asynchronous language (JavaScript). I solved this by transforming every single statement to a JavaScript Promise. This allowed us to have loops with input reading without using the default browser "prompt" feature.

Designed and coded a learning management system: a multi-tenant with live and on-demand video streams. The system supported SCORM and other custom learning objects. The client can even use other sources of content (embedding from YouTube or Vimeo), using the LMS as a gate to all the corporate content.

One of the big-wins of this project is the possibility to deploy in a very flexible way. We have the ability to use servers in the cloud or just use barebone servers inside client data centers. This allowed our clients to reduce costs with internet data transfers.

Developed a web interface for a legacy ERP (that only works in Windows desktop machines). This interface allows clients and sellers to create orders in the ERP using a browser.

I designed an approach to synchronize the data between the two points. To keep things synchronized, I used an approach in the layer that talks to the ERP that gets all the orders made online, and when they are inserted in ERP, these layers send an alert to the server so during the next update cycle this order is not accepted. In this alert, it also provides to the web interface the internal ID so new updates could be tracked as well.
