Software Engineer

Joined the Power Automate Desktop service backend team responsible of scheduling Desktop flow runs on clients machines. Developped a smarter machine selection algorithm to assign runs to the correct machines faster and reduce time between a Desktop flow being the next in queue and being actually run. Became the main developer of the Dataverse solution leading the development and integration of new features with the platform.

Work on Power Automate Process advisor backend team from the start of the project to the Public Preview. Develop the Dataverse solution and work on integrating the product with the platform. With integration of lifecycle management in the data model from the beginning. Development of a console client tooling to improve debugging of new and existing features.

Work on AI Builder from the start of the design to the public preview release and through the General Availability phase.

Design and implement multiple cross-scenario backend platform features, like the license checker, lifecycle management features (import and export of AI models), handling of backup and restore processes and an internal console debug tool. Work on improving performance of the Schedule Prediction feature, improved performance 100 fold by rebuilding the feature from scratch and batching requests. Collaborate on cross-team convergence efforts to reduce code duplication and allow every scenario to benefit from all the platform features.

Work with the Dynamics 365 Customer Insights team to implement platform integration features. Add ability to export customer segments created in Customer Insights to Dynamics 365 for Sales.

Work on the Microsoft Store Books ingestion team. Work in collaboration with remote teams to improve ingestion and store experience. Work to add new books providers to the store to grow the books catalog selection. Implement new features like preorder for the books in the store. Work on the sunset of the books category of the Microsoft Store.

Work on the Microsoft Store User Generated content ingestion team. Work on the new pipeline to push user submitted content to the Microsoft Store with the ability of having manual validations. Develop a dependency orchestrator using Azure Durable Functions to check educational content in order to automatically remove and report illegal content.

Software Engineer Intern

Work in Amazon Logistics on an internal delivery tracking platform that allows all delivery station managers to better manage their deliveries by looking at real time metrics.

As part of this job, I implemented new features in the Ruby on Rails website and worked on Lambda functions written in Java. I also developed Machine Learning project (using LSTM) allowing users to see prediction of future values of the metrics for each of the delivery stations. This project was then deployed on AWS and is displaying the values in a user friendly way on the platform.

Ask Me Anything

An Hackathon project done in 3 days at Microsoft. It allows to setup a Q&A with ability for users to vote on which questions they want answered first.

The idea is to allow anyone to ask questions during large remote-first Ask Me Anything meetings that are common in large companies in times of pandemic. Adding the ability to vote makes it possible for the best questions to be answered first and adds interactivity that is not present in traditional in-person Ask Me Anything sessions.

The project contains a “Presenter view” that can be shared during the meeting so that everybody can follow and read along the questions. This view contains a QR Code allowing viewers to ask their questions or vote.

Web Extension: Web Rating

An Hackathon project done in 3 days at Microsoft.

The idea is to allow everybody to rate and comment any website page they come across on the web. These rating and reviews can then be used by other users to decide whether a page is of interest to them or not. It also displays the rating of pages on links as they appear and before they are clicked on.

The project is shipped as a browser extension that can be installed in Microsoft Edge, Chrome, Firefox, and any Chromium browser.

Tiger Compiler

Developing a compiler for the Tiger Language (modified version of Andrew W. Appel Tiger’s language) in C++14. This project is separated in many phases, each one depending of the success of the previous one. First of all there is the lexer and the parser, that were done using Flex and Bison. Then, after making sure that we recognized correctly the Tiger language we built the AST using the parsing made by Bison.

We also had to create a pretty printer for the language in the same phase. The Visitor design pattern was used to create it. The pretty printer is useful during the whole project to see what the compiler did and to test the project.

The whole project is so huge it must be tested thoroughly, this is why we created a Ruby test suite to test the project. The test suite has a complete HTML output to ease debugging. After this phase we created the Binder which is supposed to bind every variable, function and type use to their declarations.

The next phase we developed is the Type Checker. The Type Checker is a part of the program that checks for type compatibility for expressions to be sure the program is correct. This part allowed us to develop as a bonus a function overloading addition to the language.

We also implemented an inliner, a pruner, an array bound checker and for desugaring as a bonus to make this compiler better.

The last phase we developed is converting into an high intermediate representation of the Tiger code, in the tree language to be able to execute the code. This phase rely heavily on having the previous parts correct to work correctly. At the end of the project we had a complete front end for the compiler. And were able to execute the Tiger code using the HAVM which is able to execute the tree code.

We succeed very well in this project. Having 100% success rate at all mandatory phases and most of the optional ones.

Runners

Video game (Tower defense) development in C++14 during a 48 hours rush using the SFML library.

42sh

A POSIX shell following the SCL, developed in C by a team of 4 people in 3 weeks. It should reproduce the behavior of bash with the ‘–posix’ option. This shell was heavily tested by more than 150 tests to check the behavior of the program against bash behavior. This project contains several separated parts including:

• lexer (transforming the input to a list of tokens)
• parser (LL parser, creating the AST from the token list)
• execution (executing the AST given by the parser)
• built ins (recreating the most common built ins)
• redirections (redirections and pipe of commands)
• executing programs from PATH and current directory
• storing history in history file
• executing conditionals instructions (if, for, while…)
• read line (create a good read line with history support and common shortcut)
• test suite (ruby test suite to check the behavior)
