Desarrollé nodos para CFDI 3.3, validaciones de anulaciones en FBRA mediante CALL TRANSACTION a F-28, actualizaciones masivas de documentos contables usando SHDB y emisión de etiquetas XML de contabilidad electrónica. Ahí aprendí a trabajar con procesos críticos de negocio y a respetar los lineamientos fiscales.

Posteriormente, en CHEETAHTEC (2018–2019) me desempeñé como Desarrollador SAP ABAP, creando reportes Z y programas Module Pool con pantallas de selección avanzadas. También ajusté formularios de facturación en SmartForms/SmartStyles, agregando nuevas fuentes y datos provenientes de la transacción VF03, lo que permitió al cliente cumplir con requerimientos específicos de impresión y facturación.

De 2019 a 2024 trabajé en MITSUI / ValíaEnergía como Consultor SAP ABAP & BW, encargado del desarrollo de reportes, tablas y vistas personalizadas, así como del mantenimiento de SAPScripts y SmartForms. Automatizé procesos y brindé soporte técnico a usuarios clave. Configuré la conexión entre SAP ECC y BW, desarrollando extractores y gestionando objetos en BW, además de participar en la integración de BW con Power BI para la construcción de dashboards y en un proyecto Fiori configurando roles y autorizaciones.

En STC Metro (proyecto BW, 2024–2025) trabajé como Consultor SAP BW y BO, ajustando cargas Delta entre ECC y BW, revisando y modificando reportes en SAP Web BO. Desarrollé también un programa en Python (SQLAlchemy, Pandas, NumPy) para optimizar consultas a SQL Server, crear tablas e integrar datos desde Excel, consolidando información de presupuestos.

Actualmente colaboro en CAPSYS (2025–a la fecha) como Consultor SAP ABAP, desarrollando programas para dispositivos handheld mediante la transacción LM01, permitiendo gestionar órdenes de traslado, pesaje y movimientos de almacén en tiempo real. He contribuido a mejorar la operación en planta mediante la optimización de pantallas y de la lógica de negocio, enfocándome en soluciones claras, estables y fáciles de usar para el usuario final.","rawText":"Comencé mi trayectoria en 2017 en ATOS como SAP Consultant 1, participando en proyectos de finanzas y facturación electrónica.

Meu nome é Júlio Costa. Sou especialista em Marketing Digital com foco em Copywriting e Redação de Artigos. Como copywriter, a minha função é estimular a mente do leitor(a)/visitante e convencê-lo(a) a realizar uma ação, normalmente uma compra. Para isso, sempre realizo uma pesquisa do público alvo em busca de conhecer as dores, mitos, desejos e objeções. Além, é claro, de reunir com o especialista a fim de conhecer os objetivos que ele(a) deseja alcançar. Portanto, ter clareza sobre as necessidades do público para o qual você pretende vender é fundamental para o sucesso do seu produto. Essa é uma das minhas maiores qualidades como copywriter: só começo a escrever depois de uma pesquisa minuciosa, sobre o seu produto, concorrentes e principalmente sobre o seu público ideal. Por conta disso, o meu prazo de entrega costuma levar mais de 5 dias. Claro que isso vai depender muito da complexidade da sua demanda, cada projeto é único. Uma copy de boa qualidade demanda tempo e esforço para ser produzida. Somente assim a ela vai ter uma elevada taxa de conversão. Em outras palavras: muito mais dinheiro no bolso! Já produzi copies para Home Pages Landing Pages e-mail VSL Script de Vídeos Criativos Posts para Instagram Nos nichos Saúde Pets Relacionamentos Sedução Desenvolvimento Pessoal Produtos para Agro Entre em contato comigo para saber mais. Ficarei feliz em sanar todas as suas dúvidas.","logos":{"normal":{"url":"https://workana.s3.amazonaws.com/logos/c51df05407507a3aa81555d7ac5c7276/im/ResultadoFoto_SorrindoGREEN3_160_160.jpg","width":160,"height":160},"thumb":{"url":"https://workana.s3.amazonaws.com/logos/c51df05407507a3aa81555d7ac5c7276/rj/ResultadoFoto_SorrindoGREEN3_30_30.jpg","width":30,"height":30},":original":{"url":"https://workana.s3.amazonaws.com/logos/c51df05407507a3aa81555d7ac5c7276/cm/ResultadoFoto_SorrindoGREEN3.jpg","width":433,"height":490},"profile":{"url":"https://workana.s3.amazonaws.com/logos/c51df05407507a3aa81555d7ac5c7276/ux/ResultadoFoto_SorrindoGREEN3_192_192.jpg","width":192,"height":192},"large":{"url":"https://workana.s3.amazonaws.com/logos/c51df05407507a3aa81555d7ac5c7276/ic/ResultadoFoto_SorrindoGREEN3_300_300.jpg","width":300,"height":300}},"country":"BR","lastActive":"2025-12-23 15:56:45","created":"2021-12-18 16:27:10","open":0,"active":0,"completed":"0","rating":"0.00","paid":0,"verifiedPaymentMethod":true,"worker":{"id":4202293,"slug":"julio-costa-15","canInvite":false,"skills":{"507":{"id":507},"513":{"id":513},"902":{"id":902},"379":{"id":379},"421":{"id":421},"387":{"id":387},"894":{"id":894},"386":{"id":386},"523":{"id":523},"504":{"id":504},"908":{"id":908},"274":{"id":274},"280":{"id":280},"207":{"id":207},"1028":{"id":1028},"499":{"id":499},"67":{"id":67},"376":{"id":376},"437":{"id":437}},"history":"Como freelancer, eu já trabalhei na produção de copys de Padarias e de alguns produtos físicos.","rating":4.96,"ranking":112,"position":{"position":"hero","next":null,"name":"Hero","description":"Hero es el máximo nivel de los freelancers de Workana.
