After obtaining a Master's degree, I have done from a simple building plan, Exterior rendering & Interior Design to Landscape, Structural, Electrical design, and Civil engineering since 2015. These years, I have been doing designs of digital and green architecture renderings using BIM (Revit, AutoCAD, and 3Ds MAX) - which are popular professional tools. With a passion for exceeding my clients' goals, I've been always passionate about design, colors, materials, styles, environment, and how things work together to always satisfied clients with high-resolution quality! My strengths are being organized with good time management but also still being flexible for any urgent changes. Some backgrounds: Since then I’ve worked, mostly with US clients and have therefore familiarized myself with popular styles in the US, such as craftsman, ranch home, traditional, colonial-style, farmhouse, cottage, shed, barn, Chicago style. Sometimes, I get to work with Spanish, Italian, Mexican, and Japanese homes too. Here are my design skills; ✅ Revit, AutoCAD, 3DMAX, Solidworks, Lumion, and Photoshop ✅ Blueprint and MEP Plan, Floor plan, Site plan, Landspace plan ✅ Interior design, Exterior rendering, Product modeling, and Furniture Design menos
