Experience

  • Belatrix Software | Big Four Accounting Firm

    While working at Belatrix Software, I worked as a tech lead on a project with a major accounting firm from the US—leading a team of three other engineers in the development of a cloud-based app.

    I was responsible for making architectural decisions regarding the application and implementing a part of the solutions that were designed. The app was an event-driven system that processed data ingested from several sources. The system also included an Angular app and a GraphQL back end, which let users visualize and edit the information ingested in the system.

    I made modifications and implemented several new features in the app, working daily on the back end with Lambda, CloudFormation, S3, and Step Functions. I also implemented the authentication mechanism for the front end.

  • Tripviary

    Tripviary is a company focused on providing a platform for tourists to connect with local tour guides and operators in Peru. The app allows users to browse through all available tours, see tour availability, and book tours right in the app.

    This platform includes features for tour operators to manage teams of guides, manage availability, and easily control bookings for a whole group in a centralized calendar. Tour operators can also assign tours to different guides, who can later see information from all the tour operators they work with. The platform also helps operators manage and control accounting, billing, expenses, payouts, and sales reports.

    The internal admin portal allows the Tripviary team to manage all tour bookings, as well as tour listings and tour operators and their teams.

  • Patient Medical Data Management

    I built an application that allowed a medical practice to manage patient medical information related to insurance claims, have the teams of employees registering the information offline on remote locations, and enabled the insurance company employees to have access to the real-time status of any given project.

    The app allowed patient information and files to be registered while being offline and then synced everything with a cloud application on AWS. This information was instantly made available to other employees in both the medical practice and the insurance company involved.

  • FIFA World Cup Betting Pool

    This web app allowed users to sign-in through Facebook and participate in a ranked betting pool after paying an entry fee.
    Users could simulate all possible outcomes for the World Cup by assigning results to each match in the cup and see instantly what the outcomes would be in the later stages based on their predictions and bets.

  • Construction Project Management ERP

    This ERP system was implemented to manage various aspects of construction projects, including engineering
    requirements, versioned budgets, payroll, accounting, logistics, and management.

    This system allowed the construction company to have custom-built reports that provided insight into all the listed aspects of the business. It facilitated coordination between separate departments in the company and reduced the time taken to manage the mentioned aspects of the projects.

  • A Jira Implementation for Process Improvement | VisaNet

    Two workflows in the IT department were analyzed, modeled, and automated in Jira, as part of their process improvement project. One of the workflows dealt with bug reporting and testing, while the other one was a much more complex workflow where the IT department evaluated potential new features in the company’s services, prioritized them, implemented, tested, and deployed them. This last workflow involved roles in all areas of the IT department.

  • Process Improvement | La Positiva

    As part of their process improvement project, several workflows in the IT area were analyzed, modeled, and implemented in Jira. These workflows used both Jira APIs and existing functionality and required a custom functionality to be implemented in Groovy to modify Jira’s default behavior.

    The workflows included activities that took place to address reported bugs, to implement new features in the company’s software, and testing and QA activities.

    For all the workflows, I was responsible for meeting with a representative of each role involved at each stage and carrying out the design, implementation, testing, deployment, and user testing for all implemented features.

    I also implemented custom reports as plugins in Jira that allowed management to have a detailed understanding of the resources spent across all current projects in the IT department in terms of both hours and cost, taking into account individual developer rates for both in-house and outsourced developers.

  • Process Improvement | SUNAT

    I built custom Jira reports as plugins that aggregated information about test plans, test cases, and test results, including bugs found in tests.

    For other reports, I also built gathered information about the time logs registered by developers in issues, sub-tasks, and related issues—presenting a detailed summary of hours spent along with a multitude of projects to management.
