About me

My journey, point by point

A journey built across data, automation, and development — always connecting real problems to practical solutions.

  1. 01The beginning

    Data taking shape

    My journey began by creating Power BI dashboards, transforming information into clearer, more useful analysis.

  2. 02The expansion

    New tools, new possibilities

    I expanded my knowledge of Python, Excel, SQL, and web development to organize information, improve traceability, and reduce manual tasks.

  3. 03Today

    A developer in constant evolution

    I am a junior developer and a Systems Analysis and Development student interested in software, data, and process automation.

I like to understand the problem before building the solution. I am curious, dedicated, and committed to learning and creating projects that deliver real results.
