Já participei de programas de aceleração de startups, onde tive a oportunidade de desenvolver habilidades de gestão e visão de produto, alinhando as decisões técnicas aos objetivos de negócio — com entregas ágeis e foco em validação.

Tenho background em desenvolvimento nativo com Kotlin e Swift.

Áreas de interesse incluem:

  • Arquitetura de software em contextos mobile
  • Automação de entrega e versionamento
  • Testabilidade e rastreabilidade
  • Observabilidade e controle de falhas
  • Alinhamento entre produto e tecnologia
