Designed, implemented and deployed a web application (C#, .Net, visual studio) with an SQL database in the backend to manage digital assets owned by T-Mobile.Designed, implemented and deployed a web application (C#, .Net, visual studio) with an SQL database in the backend to assist security engineers in preparing security surveys and requirements, prioritizing and tracking the implementation of T-Mobile security controls.

As a Security Certifier, I made sure that services and applications complied with security policies. I reviewed design documents, created threat models, performed manual and automated code reviews, performed test and suggested changes.As a Software Engineer, I was involved in the implementation of tiered payments to sellers. I implemented a workflow (java, Herd, SQS) to retrieve and process tier information and send results to a message queue. I coordinated with the data science team to select compatible technologies and confirm the required configurations.As a Software Engineer, I re-implemented a disbursement system. I implemented a workflow (java,Herd) to process disbursements. I implemented metrics and graphs to track transactions in production.

Used Model-Based Testing and Windows Test Technology (WTT) to test the connectivity of Apple devices and validate scenarios involving these devicesManaged the redesign of an online internal library using C#, HTML and SQLGathered the requirements from the administrators of the libraryOrganized the features to be implemented and scheduled the tasks to be completedImplemented the requested featuresTested the implemented features and fixed the reported bugsRedesigned the database and cleaned its contentDeployed several iterations of the library with new features and bug fixesUsed C#, WTT, Test Authoring and Execution Framework (TAEF) and in-house and third-party applications to automate UI tests involving scenarios related to printing in order to discover regressions before releasing updates to Windows 10

Created an SQLite database to store the relevant data for all the computers within the companyDeveloped a Perl script to extract data from a Sybase database and store it in the SQLite databaseExtracted from stored procedures written in T-SQL the information related to the provenance and the intermediary processing steps of each relevant piece of dataDeveloped Perl scripts to store extracted information into the SQLite databaseDeveloped a bash script to backup the SQLite database and the related scripts and input files

Developed an application to test the compliance of data with a set of rulesReverse engineered a rules engine to generate a UML model of its internal structureUsed the model of the rules engine to implement the backend and user interface of the applicationImplemented the backend using Perl, MooseX, DBIx and LibXML in order to generate rules, pass them to the rules engine and store them in or retrieve them from a databaseImplemented a user interface using Flex and ActionScript to allow a user to manage rules and apply them on selected dataImplemented Web Services using SOAP to allow data to be transferred between the user interface and the backendGave a demonstration of the application and explained the main features to a team of developers responsible for maintaining and supporting the project

Developed a set of smoke tests to test the basic functionalities of a messaging application called iAlertRefactored parts of the back-end code of iAlert to generate XML data with a uniform structureReplaced all the SQL statements found in the back-end code of iAlert with constructs from the DBIx perl moduleCreated a library using the logic found in the back-end code of iAlert and the MooseX perl moduleRemoved the redundancies found in the back-end code of iAlertFixed reported bugs related to the back-end code of iAlert

Developed shell scripts using bash to set up the environment and clean up the generated files when executing the test cases of a given test suiteRefactored an awk script to more efficiently categorize files using an input file containing the necessary informationDeveloped a script using Perl to extract the relevant data used to create an input fileImplemented a feature using Ruby to keep track of the number of failures of a given job and remove that job if the number of failures reaches a predetermined threshold
