Software Engineer | Mobile Developer

2015 - 2016
Virtualmind (Software House)

Self-employed
  • Worked on my own apps and garnered experience with new technologies.
  • Created an app using Parse as the back-end with push notifications and workers.
  • Developed my first app to help people to find the best bus combination to reach their destinations and probably the hardest part was developing the algorithm to minimize the user walking distance and travel time.

Software Engineer | Mobile Developer

2013 - 2015
Making Sense
  • Worked as an Android developer at Making Sense and was involved in several projects with clients mainly from the USA. Most of the apps were of the app type that used a REST API so I perfected my handling of them and improved the communication between the app and the server.
  • Developed a framework with one of my coworkers to handle the communication between an app and the API following the best practice (Google I/O) which we used later in many projects.
  • Built a web-hybrid app—implementing the communication with the web app and adding new native views.
  • Led a small team of a social media app—coordinating with the client, the design team, and the development team.
Technologies: REST APIs, Android

DREAMer's Roadmap

https://play.google.com/store/apps/details?id=com.dreamers.app
I developed entirely the Android app version of DREAMer's Roadmap, a mobile app designed to help DREAMer’s—undocumented students—find and track scholarship opportunities available for them across the nation.

The app will also work as a crowd sourcing platform where anyone can suggest a scholarship they know about that are not on our data base. DREAMers Roadmap will also be a great resource for educators, making it easy to share our information via email and social media with their students.

Request Service Helper

With one of my coworkers, I built a class in architecture to handle the communication between an app and REST API. It follows the best practices given in a lecture on the Google I/O 2010 - Android REST client applications by Google for Developers. This layer-based architecture uses services, processors, content providers, and volleys to perform the request in the background and constantly synchronize with the database.

RxJava with RetroFit and Realm

A simple example of how to use RxJava with RetroFit to fetch data (background thread) from an API and save it using Realm.

Treggo

https://play.google.com/store/apps/details?id=ar.com.treggo.cliente&hl=es
I led the development of both platforms, iOS and Android. The idea of the app is to allow users to request a messenger instantly with real-time tracking using Google Maps.

Kapture

Kapture is an audio-recording app connected to a wearable device which is listening all the time. It’s a complete set of tools which allow you to make your moments heard. The device allows you to capture the last 60 seconds of audio at any moment.

FunPoint Club

I was in charge of the Android team and worked as an Android developer. I coordinated the communication between the client, API, and designers. I also ensured the quality of the final product.

FunPoint Club is a social network and a complete guide to bars, nightclubs, and events to go out with your friends that filters places where you currently are. It is a platform that lets you find out about discounts, promotions, and benefits of each bar. You can create new points and share them with friends. FunPoint Club is your pass to fun.

Blue

I created and designed an application to consult the currencies of the parallel dollar and the official dollar in Argentina. I used Parse for the back-end, material design, and push notifications.

Bus App

I created and developed this app on my own. It started out as a personal challenge. It arose from a situation that I encounter frequently. Almost every day, I ride the buses in my hometown of Mar del Plata, Argentina. I’ve experienced firsthand how hard it can be to learn the various bus routes, stops, and connections.

It is an Android application which helps people to find the best bus line, you can select the origin and destination and see the suggested lines. Also you can see all the bus routes and your current location.

LIN Media

I was in charge of the Android team and worked as an Android developer.

LIN Media is a local multimedia company that operates or services 43 television stations and seven digital channels in 23 U.S. markets, and a diverse portfolio of web sites, apps, and mobile products that make it more convenient to access its unique and relevant content on multiple screens.

Practice Fusion

http://www.practicefusion.com/
I was in charge of the Android team and worked as an Android developer on a hybrid web app with some native views.

Practice Fusion is a free web-based electronic health record (EHR) company founded in 2005; operated and privately owned by Practice Fusion, Inc. in San Francisco, California. The SaaS startup provides physicians and medical professionals with free advertising-supported EHR and medical practice management technology that includes charting, scheduling, e­-prescribing (eRx), medical billing, lab and imaging center integrations, referral letters, meaningful use certification, training, support, and a personal health record for patients.

Song Fanatik

I was in charge of the Android team and worked as an Android developer.

We extended an existing application, and added a new functionality and a new skin (bug-fixing included).

The app that we extended was called Song Fanatik. It's a social network where you can find cover song videos, discover new artists, vote for your favorite versions, and even give out awards.

Sayer

I worked as a Web API developer for this project. The RESTful API was developed in C# (Visual Studio).

Description of the app:
Whether it's sports, the stock market, weather, politics, entertainment, or the world around us, we share a fascination with the uncertainty of future events. Sayer, a mobile app, will be the place where you can pose and answer predictive questions on topics that interest you, challenge your friends, gain points, and see how you stack up on the leaderboard.
