Desenvolvedor full-stack com foco em frontend. Transformo problemas complexos em interfaces claras, rápidas e agradáveis de usar.
Sobre
Sou Marcos, desenvolvedor full-stack com foco em frontend e estudante de Engenharia de Software. Atuei como principal desenvolvedor do frontend de uma plataforma de dados intensivos para a Petrobras, em parceria com o CeMEAI, trabalhando com gerenciamento de estado, visualização de dados e integração com APIs assíncronas.
Também atuo no backend com Python/FastAPI e já trabalhei com Java/Spring, PHP/Laravel e serviços na AWS. Tenho experiência com mobile (React Native e Kotlin), testes automatizados e liderança de equipe — ensinei programação e coordenei bolsistas no desenvolvimento do SAVE, na UNIPAMPA. Valorizo boas práticas e código limpo.

Gestão de fretes agenciados — do embarcador ao motorista
Sistema interno que conecta embarcadores (quem tem carga) a transportadoras e motoristas autônomos (quem tem veículo). Torna visível o spread da agência e responde "cadê minha carga?" sem depender do WhatsApp, com controle de acesso por papéis, rastreamento de fretes e uma base dos 5.570 municípios do IBGE.
Frontend de aplicação de dados intensivos
Aplicação web de dados intensivos desenvolvida para a Petrobras em parceria com o CeMEAI. Atuei como principal desenvolvedor do frontend, lidando com fluxos complexos de tratamento de dados, gerenciamento de estado, visualização e geração de relatórios.
Replays de CS2 reconstruídos em um mapa 2D
Plataforma que faz o parse de demos de Counter-Strike 2 e reconstrói a partida em um mapa 2D interativo, com movimentos e eventos do round. Upload direto para storage em nuvem e processamento assíncrono.
Construtor de surveys full-stack (liderança de equipe)
Plataforma para criar e aplicar pesquisas com egressos dos cursos de computação da UNIPAMPA: construtor de questionários drag-and-drop, autenticação por papéis, internacionalização, dashboards de resultados e exportação em CSV/PDF. Liderei e mentorei a equipe de bolsistas.
Gestão de cuidados a partir de protótipos reais do cliente
Sistema de gestão para o Residencial Geriátrico Viver: cadastro de residentes, rotinas de cuidado e controle de acesso por perfil (administrativo, secretaria, cuidadores, médico, fisioterapeuta e nutricionista). Desenvolvido a partir de proposta e protótipos reais do cliente.
Projeto pessoal — React + Spring Boot
Site de receitas full-stack, construído para praticar a integração entre um frontend em React e uma API REST em Spring Boot, com upload de imagens para o AWS S3.
