Transformo operações reais em automações, regras de negócio e aplicações backend testáveis.
What I'm looking for
Na OMNIA Pilates e Fisioterapia, transformo regras de agenda, alunos, sessões e check-ins em requisitos, critérios de aceite e uma solução interna integrada a planilhas, em evolução para PostgreSQL e Supabase.
Também desenvolvo projetos freelancer com Python, TypeScript, React e Node.js, incluindo conciliação fiscal de planilhas e um projeto experimental de IA com retrieval, observabilidade e aprovação humana. Minha experiência em pesquisa e Controle de Qualidade reforça meu foco em testes, validação de dados, rastreabilidade e investigação de falhas.
