Você fala comigo do diagnóstico à entrega. Sem gerente de contas, sem repasse para júnior, sem descobrir na terceira semana que quem vendeu não é quem executa. Assino meus projetos como NavalBrands, minha marca. É o padrão que eu me obrigo a cumprir, não uma agência com sala cheia. O QUE EU FAÇO Descubro por que o seu negócio não converte e reconstruo a peça que está travando: posicionamento, oferta, site, ou as três, quando o problema é de fundação. Marca e landing page tratadas como problema de receita, não como problema de estética. COMO EU TRABALHO Começo por diagnóstico, sempre. Antes de propor qualquer coisa eu olho o seu site, o seu concorrente e a sua oferta. Se eu achar que o que você está pedindo não vai resolver o seu problema, eu digo isso na primeira mensagem, mesmo que custe o projeto. Meu foco é em te gerar resultado! Só aceito o que eu mesmo executo. Se não couber no meu prazo, eu recuso na hora. MINHA PROVA 33 projetos entregues aqui, 33 avaliações, todas 5 Estrelas. Zero violações em 3 anos de plataforma e mais de 10 anos de carreira na indústria criativa. 667º lugar entre 14,6 milhões de profissionais da plataforma. Não te peço para acreditar em mim.

É o que separa executar um pedido de resolver um problema. Dois clientes podem me pedir exatamente a mesma coisa, um site novo, e precisarem de soluções completamente diferentes. Para um deles o site é mesmo o gargalo. Para o outro o site está bom, e o que trava é o preço aparecer cedo demais, ou a oferta estar competindo com o concorrente errado. Entregar o mesmo site para os dois atende o pedido e não muda o faturamento de nenhum. Por isso eu começo sempre pelo número que você quer mover: ticket médio, volume de contatos, taxa de fechamento. A partir dele eu decido com você onde mexer. Às vezes é a marca, às vezes é a página de vendas, às vezes é só a ordem em que a informação aparece para quem está decidindo. É um trabalho de menos entregáveis e mais decisão. Por isso eu cobro mais caro e entrego menos itens. ONDE EU SOU FORTE - Posicionamento e reconstrução de oferta; - Identidade de marca para operações que querem subir de faixa de preço; - Landing pages e páginas de venda com estrutura de conversão; - Diagnóstico comercial: descobrir onde exatamente o dinheiro está vazando. ONDE EU NÃO SOU A PESSOA CERTA Não pego arte avulsa, carrossel isolado nem alteração pontual. Não é esnobismo. É que nesse formato eu não consigo entregar nada que justifique o meu preço, e você vai encontrar gente melhor do que eu para isso por bem menos. IDIOMAS Converso e entrego em português. Projetos com entrega final em inglês eu aceito com revisão nativa contratada por mim, e combino isso com você antes de começar, nunca depois.","rating":5,"ranking":86,"position":{"position":"hero","next":null,"name":"Hero","description":"Hero es el máximo nivel de los freelancers de Workana.

Mi enfoque es simple: datos, ingeniería de adquisición y cero tonterías. Lo que he hecho últimamente (y que a tu negocio le vendría bien): Vender 50 veces más: Facturé 100k USD en 90 días invirtiendo solo 2k en anuncios. No fue suerte, fue optimizar el funnel hasta que no quedó otra opción que comprar. Conversión de locos: Mantengo un 43% de tasa de conversión en e-commerce. Si no sabes si eso es mucho o poco, probablemente estés perdiendo una fortuna cada día. Vendedores que no duermen: Implemento sistemas de IA que califican, atienden y cierran ventas de forma autónoma. 24/7. Sin pedir vacaciones ni quejarse del café. Estrategia global: He escalado marcas en Latam, Europa y EE.UU. priorizando el dinero en la caja (ROAS) sobre los aplausos en las reuniones. ¿Qué NO hago? No pierdo el tiempo con tácticas de moda, humo de colores ni "engagement" vacío. Si no tiene tracción real y los números no cuadran, lo elimino.

Trabajo por etapas: primero diagnostico el estado del proyecto y detecto los puntos críticos, luego propongo una solución ordenada y avanzo con el cliente informado en cada paso. Nada de sorpresas ni entregas a ciegas. ¿Necesitas una web nueva, arreglar errores o dejar tu tienda online lista para vender? Escríbeme y te doy un primer diagnóstico de tu proyecto.","logos":{"normal":{"url":"https://workana.s3.amazonaws.com/logos/9e6dd8129121858084ae180f86286604/zm/elvia_160_160.jpg","width":160,"height":160},"thumb":{"url":"https://workana.s3.amazonaws.com/logos/9e6dd8129121858084ae180f86286604/wv/elvia_30_30.jpg","width":30,"height":30},":original":{"url":"https://workana.s3.amazonaws.com/logos/9e6dd8129121858084ae180f86286604/hl/elvia.jpg","width":956,"height":1280},"profile":{"url":"https://workana.s3.amazonaws.com/logos/9e6dd8129121858084ae180f86286604/bb/elvia_192_192.jpg","width":192,"height":192},"large":{"url":"https://workana.s3.amazonaws.com/logos/9e6dd8129121858084ae180f86286604/uf/elvia_300_300.jpg","width":300,"height":300}},"country":"SV","lastActive":"2026-10-07 13:28:12","created":"2015-02-25 14:28:30","open":0,"active":0,"completed":"53","rating":"4.91","paid":53,"verifiedPaymentMethod":true,"worker":{"id":152829,"slug":"elvia-barrera-2","canInvite":false,"skills":{"362":{"id":362},"485":{"id":485},"173":{"id":173},"174":{"id":174},"123":{"id":123},"699":{"id":699},"467":{"id":467},"308":{"id":308},"529":{"id":529},"283":{"id":283},"807":{"id":807},"909":{"id":909},"748":{"id":748},"120":{"id":120},"518":{"id":518},"274":{"id":274},"188":{"id":188},"513":{"id":513},"947":{"id":947},"1051":{"id":1051},"490":{"id":490},"853":{"id":853},"526":{"id":526},"830":{"id":830},"901":{"id":901},"531":{"id":531},"67":{"id":67},"437":{"id":437},"499":{"id":499},"525":{"id":525}},"history":"Cuento con más de 11 años de experiencia desarrollando sitios web, tiendas online y soluciones digitales para emprendedores, empresas y agencias.
