2025
● Initially hired as Junior Software Engineer, later promoted to Mid-Level and then Senior Software Engineer.
As a Senior Software Engineer, I:
● Led the support team, mentoring three newly hired junior developers. The mentoring program was praised for its impact on junior developer growth and for significantly reducing support tickets.
● Participated in the development of a cloud-based application using DDD architecture. I built .NET microservices consumed by the legacy system and also implemented the corresponding frontend integrations.
● Developed a new activity assignment feature for documents, allowing managers to assign tasks (such as analysis, correction, or review) directly through the system, replacing a previously manual process.
As a Mid-Level Software Engineer, I:
● Contributed to the modernization of the legacy system, developing new features based on user requests, including a table column configuration tool — widely praised by users and later replicated across other system modules.
● Helped build a new system from scratch for generating dynamic forms, where managers could drag and drop components (text, number, date) using the Form.IO library with an Angular frontend. Other users could then fill out the form and generate a PDF.
● Designed and implemented backend services using C#, .NET 6, and Entity Framework within a hexagonal architecture. Used Scaffold-DbContext to map database models provided by the DB team following a Database-First approach.
As a Junior Software Engineer:
● Worked on the support team, handling tickets and bug fixes for the organization's main legacy system based on MVC architecture, using C#, .NET, JavaScript, HTML, CSS, and Oracle Database.
