CORREÇÕES DE CÓDIGO LIMPO RESOLVEM O PROBLEMA DE VEZ


Eu encontro o problema real, conserto de forma adequada e documento tudo. Seu site, app, painel ou painel de administração permanecem limpos e estáveis após cada correção.


O QUE EU CONSERTO:


  • Site não carregando ou exibindo tela em branco
  • Botões, formulários ou funcionalidades não funcionando
  • API não conectando ou retornando dados incorretos
  • Login, cadastro ou pagamento não funcionando
  • App travando ou gerando erros
  • Desempenho lento ou layout quebrado no mobile


POR QUE OS CLIENTES ME ESCOLHEM:


  • Resposta rápida: a maioria das correções entregue no mesmo dia
  • Sempre sabe o que foi consertado e por quê
  • Comunicação clara durante todo o processo


MEU PROCESSO:


  • Encontro a causa raiz, não apenas tampo o sintoma
  • Começo lendo seu código, logs de erro e console; a maioria dos problemas se revela nos primeiros 10 minutos
  • Não tem acesso ao seu código ainda? Só descreva o que está acontecendo, eu te digo a causa mais provável antes de você fazer o pedido
  • Cada correção é testada antes de entregar
  • Você recebe código limpo com notas claras sobre o que foi alterado


Trabalho com React, Next.js, Node.js, Express, MongoDB, PostgreSQL, JavaScript e TypeScript.

I build web apps, mobile apps, and NFT platforms that actually work in production. 6+ years of experience across React Native, Next.js, Node.js, Solana, and full stack development. I have delivered custom web platforms, cross-platform mobile apps, e-commerce solutions, and NFT marketplaces. Every project starts with understanding your business — not just writing code. You get daily updates, a working preview before development ends, and post-delivery support. Web. Mobile. Blockchain. If you need it built right — let's talk.

    I hired the service and the freelancer said he would do the job 100% faithfully, and I even asked him twice before paying if he would be able to do the job. I demand a full refund; the freelancer didn't do a single animation of the stories I requested.
