Experience
  • Billing Portal Support (Development)

    Support to billing portal based mainly on PHP/MySQL. Portal receives activity tickets from USA Fire Departments (FTP Import mainly), generate invoices, calculate commissions, manages payments and connects to Quickbooks.

    Portal uses a mix of framewiorks as it has evolved over time: Started based on CodeIgniter and JQuery. New features are developed using FuelPhp and AngularJS.

    Portal had a rich amount of PHPUnit scripts.

  • Building Manager Portal (Development)

    I developed a portal for letting the building managers (1) provide information about payments received by apartment owners and (2) register invoices and expenses related to maintenance activities in the building. Information is exported to a legacy COBOL application, which splits the expenses among the apartment owners and generates a bill for each apartment. Information is then imported back into the portal to ensure it stays up-to-date. Built using PHP, Yii, and MySQL.

  • Portal for Buildings Bills (Development)

    I created a portal for an accounting studio to process expenses generated during building maintenance activities. It allows expenses to be split among apartment owners. Maintenance activities are managed by a building manager who is hired by the building. The manager is the one who hires the accounting studio for supporting its back office activities.
    I developed a portal for publishing bills created by the studio. Bills are downloaded by apartment owners.
    It is currently supporting 30,000+ monthly bills and built using PHP, CodeIgniter, and MySQL.
    Bills are uploaded through FTP and automatically indexed into the database, which sources the application. Files with updates to master tables are also fed this way.

  • Contributions to Open Source Projects (Development)

  • ALV Robot (Development)

    The site is intended to help ABAP programmers in the creation of ALV reports by automatically generating source code using a specially designed template. This simplifies and speeds up the generation of ALV reports. As they are all made from the same template, standards are consistent. The generated source code is neither messy nor complicated.
