Estou iniciando a criação de um software inteiramente novo para a plataforma web e preciso de alguém que assuma toda a programação, do desenho da arquitetura ao deploy em produção. Ainda estamos refinando os requisitos, portanto valorizo profissionais que, além de codar, consigam orientar sobre boas práticas e sugerir a stack mais adequada (React, Vue, Angular, Node, Django, ou tecnologias equivalentes são todas possibilidades). O que mais pesa na escolha será a sua experiência: conte-me, de forma objetiva, quais projetos web já liderou ou participou, o tamanho das equipes envolvidas e os resultados obtidos. Links para sistemas em produção ou repositórios públicos são bem-vindos, mas o foco deve ser mostrar como você resolve problemas de performance, segurança e manutenção ao longo do ciclo de vida do produto. Entrego o trabalho em marcos e libero cada etapa após aprovação. Ao final, espero receber: • Código-fonte versionado em repositório Git • MVP rodando em ambiente de produção estável • Documentação de instalação e hand-over • Testes automatizados cobrindo os fluxos principais Se você domina tanto backend quanto frontend e está à vontade para integrar APIs ou serviços externos, envie sua proposta destacando a experiência que mais o qualifica para este desafio.

Hi there, Vou entregar o MVP completo do seu software web, do desenho da arquitetura ao deploy em produção, com código versionado em Git, testes automatizados nos fluxos principais e documentação de hand-over. Em um projeto recente com escopo similar (requisitos ainda em refinamento), estruturei entregas em marcos semanais com um update curto ao final de cada dia. Isso manteve o cliente no controle sem travar o desenvolvimento. Perguntas: 1) O software terá autenticação de usuários ou integração com algum serviço externo específico (pagamento, e-mail, etc.)? 2) Já existe algum protótipo, wireframe ou documento parcial de requisitos, ou partimos do zero na definição? Me envie o resumo do que o sistema precisa resolver e eu monto uma sugestão de stack com cronograma de marcos ainda hoje. Send me a message and we can go over the details. Best regards, Kamran

Your project is interesting because it starts at the right place: architecture, stack decisions, and a production-ready MVP instead of only screens or isolated coding tasks. I’m comfortable leading full-cycle web application work, including backend, frontend, integrations, testing, deployment, and documentation. Since the requirements are still evolving, I would approach this by defining the MVP properly first and then building it in approved stages. That usually gives a cleaner result and avoids technical debt later.

Hi, I'd handle this using a modular architecture—React for the frontend, Node.js for the backend—because it keeps the system scalable while avoiding tight coupling. The biggest improvement will come from decoupling services early, so future changes won’t ripple through the entire codebase. A few years back I worked on a SaaS with heavy real-time reporting where switching from monolithic Django endpoints to a Node.js API layer cut average response times in half, although we had to fine-tune CORS policies afterward. Work will be delivered in discrete Git branches, each passing tests before merging to main, so you can review changes in isolation. Existing data will stay untouched until you approve the migration scripts, and I’ll include a rollback plan for the production cut-over. This means faster iterations, fewer bugs reaching users, and documentation that stays accurate because it’s written as features ship, not after the fact. If the stack makes sense, I can start with a quick review of the current requirements and outline the safest path to production. Thanks, Denis.

Your biggest risk is choosing a stack before defining your scalability targets and integration requirements. If you pick Django but later need real-time features, you'll face a costly rewrite. Quick questions - what's your expected user load in year one, and which external APIs or services will this system need to integrate with from day one? Here is the architectural approach: - PYTHON + DJANGO: I'll design a modular monolith with clear service boundaries so you can extract microservices later without refactoring the entire codebase. - VUE.JS + API INTEGRATION: I'll build a decoupled frontend consuming RESTful endpoints, making it trivial to swap UI frameworks or add mobile apps down the road. - CI/CD + AUTOMATED TESTING: I'll configure GitHub Actions pipelines that run unit and integration tests on every commit, blocking broken code from reaching production. I've led full-stack builds for 8 SaaS products that scaled from MVP to 20K+ active users, including a fintech platform processing $2M monthly transactions. Let's schedule a 20-minute call to map your requirements before locking in the architecture.

I’ve architected and delivered full-stack web systems in Django/Node with React/Vue frontends, scaling from 2 to 15 dev teams and maintaining sub-second response times under load. This fits my regular work. I’ll start with a lean Django REST backend (DRF, Postgres, Redis), Vue 3 SPA, and Docker-based CI/CD to staging. Performance and security baselines will be enforced via Nginx, Sentry, and OWASP checks; automated tests run in GitHub Actions before each merge. Repository with semantic commits, README, and one-click deployment to AWS ECS. Ready to begin immediately.

Hey, começar do zero enquanto os requisitos ainda estão sendo refinados é o cenário ideal para definir uma estrutura leve antes de codar. Eu costumo usar Node com Vue para manter o desenvolvimento ágil e fácil de ajustar conforme as ideias mudam. O maior desafio aqui é evitar que o escopo cresça demais e atrase o MVP, algo que resolvo definindo limites claros para cada entrega no Git. Vocês já têm alguma API externa definida que o sistema precisará integrar de início?
