I prepare construction quantity takeoffs, BOQ tables, cost estimates, and AutoCAD/Excel-based documentation from drawings, PDFs, sketches, markups, and project notes. My work focuses on turning construction information into clear, accurate, and review-ready deliverables. I prepare organized quantity takeoffs, material takeoff sheets, BOQ tables, cost breakdowns, drawing revisions, and structured Excel documents for contractors, consultants, designers, and project teams. Core services I deliver include: • Quantity takeoff from architectural and construction drawings • BOQ and material takeoff preparation in Microsoft Excel • Cost estimate tables, item lists, assumptions, and exclusions • Painting, flooring, wall, tile, concrete, formwork, masonry, and similar takeoff work • PDF/DWG review, redline markup updates, and drawing revisions • AutoCAD 2D drafting for floor plans, site plans, and construction drawings • Excel formatting for estimate sheets, BOQs, and cost breakdowns • Construction document formatting and PDF delivery checks For cost estimate work, I can organize quantities, work items, units, rates, subtotals, notes, assumptions, and exclusions in a clean Excel format. If local pricing is required, I can work with your unit rates, supplier quotes, subcontractor prices, or market references instead of guessing. For drawing work, I can revise DWG/PDF files, update dimensions, clean layouts, adjust walls, organize layers, add notes, and prepare clear PDF/DWG outputs based on your markups, written instructions, or Loom/screen-recorded videos. I work carefully, communicate clearly, and ask focused questions when information is missing or unclear. My goal is to deliver practical construction documents that are easy to review, price, update, and use during estimating, bidding, planning, or project coordination.

I design production-ready files for laser cutting and 3D printing — not just visuals. If you need clean SVG/DXF or STL files that work in real manufacturing (no errors, no cleanup), I can help. I focus on geometry accuracy, tolerances, and part fitting, so your designs can be produced smoothly for laser cutting, CNC, or FDM printing. 🔧 What I can help with: • Laser cutting files (SVG / DXF) — clean cut paths • 3D printable models (STL / 3MF) • Multi-part / assembly designs • Converting sketches into production-ready CAD • Fixing and optimizing existing files ⚙️ Manufacturing-focused: • Proper tolerances and clearances • No duplicate / broken paths • Watertight, clean geometry • Designed for real printing (0.4mm nozzle, strength, fit) 💍 Jewelry CAD (Rhino): I also create simple jewelry models (rings, pendants) in Rhino, focusing on clean, casting-ready geometry. Happy to follow sketches and collaborate closely on custom pieces. 🛠 Tools: LightBurn • Rhino • FreeCAD • Inkscape 👉 If you have a project, feel free to share — I’m happy to review and suggest improvements before starting.

Graduated in FBA - UNLP - Argentina. Worked in Audiovisual Productions at Caja Oscura (Independent Company). Knowledge about 3D-Modeling software and 3D-Printing. Knowledge about bicycle mechanisms and construction or repairing. Experience in graphic products for web and street comunication.

Hi, I’m a mechanical engineer with experience in different 3D modeling softwares. I enjoy designing models both for fun and freelance projects, and I also design and 3D print many of my designs whenever I come across something challenging. Along with this, I work as a market analyst and have professional experience in that field as well.

Fundamentally, I always propose a simplified work frame through ease of ways/methods, resource affordability, and opening of valuable hidden spots where many others rarely have sight on. All to lead us to immediate start to work, faster lead time, multiple failure reduction, and cost efficiency to any scope of work. Experience : product design & pricing, standard compliance (ISO 9001, IEC, ANSI, etc), process design/mapping, material & sourcing (metal, polymer, plastic), plant design & construction, machinery, commissioning, quality plan, reach of 86% efficiency of process & cost
