Desenvolvedor Backend Sênior @ PicPay

About

Engenheira de Software com uma trajetória única: migrei da precisão dos laboratórios para a arquitetura de sistemas de alta complexidade. Essa transição de carreira, realizada em 2022, foi o ponto de partida para uma ascensão acelerada. Em menos de três anos, evoluí de Desenvolvedora Júnior para Referência Técnica em uma das maiores fintechs do país, uma jornada que prova minha paixão por aprender e minha capacidade de adaptação e entrega de resultados em ambientes desafiadores. Meu foco é o ecossistema Java, onde transformo desafios de negócio em código limpo e escalável. Sou uma defensora de boas práticas de design, garantindo que as soluções sejam não apenas funcionais, mas também resilientes e de fácil manutenção. No PicPay, atuo na squad core de aquisição e conversão, uma frente vital para o negócio. Minha função vai além do código: sirvo como uma ponte técnica essencial para a área de produto, liderando refinamentos complexos, revisões de código e influenciando decisões arquiteturais que impactam diretamente a jornada de milhões de clientes. Sou responsável por garantir a excelência técnica em sistemas críticos, inclusive em regime de plantão. Acredito que a melhor tecnologia é aquela que resolve problemas reais e está alinhada à estratégia do negócio. Busco constantemente desafios que me permitam construir produtos de valor, unindo rigor técnico e visão de produto.
