Company type corporate My role
Fullstack
Period September 2018 - September 2020

The stack I mainly use: jQuery, .NET, PHP, VB6

✨ Most Significant Projects

  • Mantainance and development of the company’s ERP software
  • Implementation of new features on the 3 main web applications: B2B e-commerce, CRM, and sales management
  • Optimization of a VB6 application to update web data from the ERP

💪 Problems and Challenges

  • Learning about the architecture of the ERP and web applications (which were developed in the 90s)
  • Maintaining a VB6 application required several customizations to resolve obsolete APIs
  • Adding a custom feature flag system to the main web application to enable/disable features for specific customers
  • Improving the performance of the module that sends data from the ERP to the web (the process involved compressing packages and sending them via FTP to the web server)

🧠 Responsibilities and Skills Acquired

I took on responsibilities such as managing individual clients, defining estimates for them, and providing bug support. I learned how to approach problems despite the limitations of the old codebase. Special thanks to Alessandro, who taught and guided me: I learned to value the underlying aspects of things, starting from a low level. This allowed me to deepen my knowledge of vanilla JS, CSS, and HTML.
