I started in infrastructure: at Brazil's Federal Prosecution Service I handled hardware, networks and standardized machines. At Master MR I dove into data and automation, building Python and VBA bots, SAP extractions and Power BI dashboards for corporate clients' tax routines.
Today I'm a front-end developer at TOTVS and co-founder of Apex Dev Studio, where we build custom websites, systems and visual identities, always with the technology each project calls for.
