Work Experience

Back-end Developer

2021 - 2022
  • Developed an application to continuously synchronize JSON objects from AWS CloudWatch logs into a persistent PostgreSQL database for data analysis. The application also transformed each JSON object into table rows to improve data analysis.
  • Constructed an application to continuously synchronize HTTP logs from AWS S3 buckets into a persistent PostgreSQL database for data analysis. The application also transformed each HTTP log into table rows to improve data analysis.
  • Built an app to enable health check of specific HTTP endpoints using Go's cron jobs. The app could also be configured to chain HTTP requests, allowing deep testing of various case scenarios and logging of only specific results.

ETL System for Data Management of Wind and Solar Measuring Stations

A Dart application used to synchronize, manipulate, and transform data from measuring stations to a PostgreSQL database, allowing a quick way to access all cleansed data for report generation and overall project viability studies. The app also emits warnings via email about non-communicating stations, missing data, or troubling sensors, granting scheduling interventions to maintenance teams when they are most needed.

VBA Plugin for MS Office to Generate Automatic Reports

A VBA plugin for Microsoft Project, Excel, and PowerPoint, allowing project managers to generate automatic project reports and presentations. In addition to generating automatic charts, presentations, and KPIs, the plugin connects to SharePoint on premises to obtain additional information about action plans, giving a panoramic view of the project. Among other things, this generates physical and financial progress curves that complement the project's time progress curve. It also allows cross-data analysis with payment milestones, which is heavily used for budget planning.

Xamarin App for Project Management Integrated with MS Project Server and SharePoint On-premises

The application is used to directly access a Microsoft Project Server and SharePoint on premises via NTLMv2 authentication, allowing users to quickly assess the current state of a project. The application can list all projects on the server (and mark some of them as favorite), list all tasks and linked tasks, generate reports, and list employees involved in each task.
