Work Experience
Senior Software Engineer
2012 - 2016
Senzari, Inc.
- Wrote the automation scripting for distributed tasks, using the Luigi library, written in Python - mostly for fetching a musician's social info and ingesting it into a big database for further usage/exposition.
- Wrote, extended, and helped maintain a global Data Access Object for handling music's queries for playlists, musician's metadata, and musical recommendations.
- Briefly wrote Hadoop routines for ingesting and analyzing XML/JSON data from specific clients/providers into a database using Titan + Cassandra.
- Extended and maintained a playlist and music engine written in Django using Tastypie to expose the logic as a REST service.
- Wrote a small REST service using Django and PostgreSQL to create music profiles of clients/users, for later consumption of the rest of the services pipeline (see the Portfolio for the rest of the details).
- Wrote a set of micro/small services running on top of NodeJS to handle incoming requests, aggregate/filter/preprocess them and then pass them to a backend service (either a REST service, or a database).

Software Engineer
2005 - 2011
Novell
- Maintained the System Windows Forms library, part of the Mono framework, an Xlib-based implementation of the Windows Forms controls, to be used under Linux mostly.
- Helped to implement the Mono's Class Library (the base library layer of the .NET reimplementation, written in C#).
- Helped briefly with improving the MonoDevelop IDE port of Windows.
- Implemented some features of the C#'s compiler for the 2.0 version of the language (properties accessor modifiers, friendly assemblies/libraries, external alias qualifiers).
- Implemented some routines for the Reflection layer of the Mono framework, which expose the metadata of the running assembly/binary for further loading, binding, and inspecting (mostly done in the C side).

JavaScript Timer Implementation on Top of Mac API
https://github.com/carlosalberto/echo-js/blob/9342fbd5245d6e08cc5212db5edcb25d369e0ce6/runtime/ejs-timers.cEcho-js is an open source implementation of JavaScript 6 with early compilation and basic bindings for AppKit and Foundation.
This is the original file I uploaded to GitHub. It includes this one as the master version and also a few changes and additions made by Chris Toshok, the maintainer.

Simple IronPython AST Walker for Guessing Possible Autocompletion
https://github.com/carlosalberto/IronPythonBinding/blob/master/src/MonoDevelop.IronPython.Parser/CustomPythonWalker.csA small Python abstract syntax tree (AST) walker class I wrote that could be used for auto-completion in an integrated development environment (IDE).
This AST walker class was explicitly written as part of an add-in in MonoDevelop, an IDE for the Mono platform, which is an open-source implementation of the .NET framework. Derived from an original Python add-in, which used simple Regex and basic parsing techniques in my add-in, I used Microsoft IronPython runtime and parser.
