Mobcaster is the first crowd-funded online TV channel; a new platform focused completely on finding, funding, and broadcasting independent television online.

I integrated a team to further develop the already existing platform.

Assigned tasks included:
• Fixed bugs.
• Developed a communication system between the funder and funding recipients.
• Integrated it with the new Ooyala API to deliver media content.
• Managed the server with a load balancer and VPN.
• Implemented a player for funded shows.
• Monitored the critical project funding during the final hours and ensured that the funds were correctly transferred using PayPal.
• Updated the PayPal integration.
• Implemented the Vimeo API for a funder video direct upload and display.
• Implemented new design.

The student association manages a budget of ~5 million euros every year across 28 departments and over 260 activities. In 2008, they approached me to find a way of keeping every department organized.

The "AAUMGO" starts each year by defining in their meetings of every minimum income and maximum expense of each activity organized with the goal of not exceeding the budget amount of that year. Then, every money transfer (income or expense) must be done according and limited to the defined budget and every document associated with the activity.

This also generates the base for the "Accounts Report of the Year" book which currently is a document with more than 60 pages.

Later, a task manager was added, similar to the one described on the project "Editvalue | Recurring Tasks Manager".

An extension for brackets to integrate with GitLab.

An incomplete version of the Monopoly game demonstrating some of my AngularJS skills.

Another sample project showing my Angular and responsive skills.

In an accounting company, with more than 80 clients to organize, their software required that everything was done for each client by the due date.

Besides keeping track of the completed tasks (which can reach more than 50 tasks per month per company), it saves who did what and when it was done, any notes related to the task, stores client tasks, sends alerts of task is left open after the due time, and finally writes and save minutes that can relate with tasks if needed.

Client requirements included no pagination of companies in order to save the history of all tasks in the statuses and to save all previous tasks that for some reason ceased to exist or were replaced by new ones.

These requirements ended being a big challenge—the number of checkboxes easily reached the 1,200 boxes per page with queries taking a long time to process due to the number of relations required.

This forced the implementation of Symfony cache to speed up the query results and a lot of work doing SQL optimization.

This conference is organized once a year and every year, something new or improved was added to it. I started this project by creating a simple website with the conference.

By the next year, online registration and payments were added with automatic confirmation. Those confirmations triggered an email with a QR code which attendees needed to carry to the conference. Once in the conference, a webcam checks the QR code and prints out their badge. If everything is alright with the registration then it shouldn't take more than ten seconds from the arrival to receiving the badge. Badge delivery is then registered and a full report is generated at the end of the conference.

At the end of the conference, the printed badge which also included a QR code is read again by the camera to print out an attendance certificate. The same QR code is also used for voting for the best paper and taking online exams.

SureDone manages product listings, orders, and inventories on the largest marketplaces simultaneously like eBay and Amazon.

I worked directly with the client in their NY offices, rebuilding some of their complex forms for publishing products and their variants with all the different requirements from eBay and other storefronts.

I created our own CMS using Mean.js (a full-stack JavaScript solution) capable of managing multiple languages with different types of content (text, image, video) per type of page (content pages, galleries, contact page, and more) by editing a config file.

Due to the popularity of this project, it suffered a couple of changes over the years.

The first year the project consisted of a TV connected to a webcam (for preview before the shot) and an SLR Camera (for the actual photos). The photos were triggered by a Playstation move placed in front of the TV.

On the first day, it took more than 500 photos. Unfortunately, because of battery life problems with the SLR and PS Move and differences between the preview and the actual photos, the project suffered a refactoring.

The machine was upgraded to a Raspberry Pi with the camera module that served both as preview and photos. The PS Move was replaced by a big button in front of the TV that triggered the camera.

You can see the photos in the link above.

Around the conference area, TVs were placed to display information like schedules, sponsors, a photo gallery, and a live broadcast of what was happening inside the auditoriums.

I supported the existing website for membership registration with subscription payment methods and registration for conferences and classes organized by the club.

The lack of retail-oriented software in Symfony forced us to create Symfony plugins to manage products (product classes, products, and multiple variants) and sales. Using only ApostropheCMS as a base, we created an online store with different payment methods.

A simple interactive projection was made as a new way of displaying the conference sponsors. As the users passed in front of the projection, a curtain animation was triggered, switching between the conference logo and the sponsors.

Besides creating a website based on Apostrophe CMS, I added a plugin to generate newsletters with the website design; importing them to MailChimp using the API and sending the newsletter from the website back office.

From the first contact with a client to the project archive, every resource of the company and clients were done through this software.

Work Done:
• Schedule meetings with clients.
• Budget generators (from hour/rate and the history each task took).
• Calendar of photoshoot sessions.
• File management of each project (folders created in NAS for each type of project).
• Workflow of each project which depended on the type of project; E.g., client approval then a photo-shoot, editing, finalizing the art, printing and then finally, archiving.
• Project archive.
• Automatic task management with time tracker—closing one task, triggered the creation of a new task to the person in charge of the project.
• A system that monitored employees checking in and out via their fingerprints.
• Making the project available to salespeople through a VPN.

One of the responsibilities of a radio is to record the emission for future use or need.

And so, I developed Linux software that was able to record the radio 24/7, and in a single hour, record all the MP3 file and burn them onto DVDs, notifying the administrators when a new DVD was required to be inserted.

Unreel.me makes it incredibly simple to create, deploy and manage custom branded video apps across all major platforms, including iOS, Android, Roku, tvOS, Fire TV, and Vewd.

I was a full-stack developer for over four years, working on the API and the front-end applications, not only for mobile and desktop but also Fire TV and Roku feeds.

I was additionally responsible for reviewing and deploying new features from the team.
