About

Have a rough sketch? A PDF, scanned drawing, blueprint, image, existing CAD file, or just a set of measurements?

From 2D drafting and PDF-to-CAD conversion to detailed 3D modeling and product design, your existing information can be turned into clean, accurate, and editable CAD.

Services include:

🔹 PDF, scanned drawing & image to CAD
🔹 Hand sketch to CAD
🔹 PDF to DWG / DXF
🔹 2D CAD drafting and technical drawings
🔹 Blueprint and floor plan conversion
🔹 Existing drawing recreation and cleanup
🔹 CAD modifications and revisions
🔹 3D CAD modeling
🔹 Product design and development
🔹 Manufacturing-ready CAD models
🔹 3D printing models and STL preparation
🔹 Reverse engineering from drawings, images, or physical references
🔹 Product visualization and rendering

Whether the starting point is a rough hand sketch or an existing technical drawing, the goal is the same: turn the available information into a precise, usable CAD file.

Drawings are created with attention to dimensions, scale, geometry, tolerances, and detail, with organized and editable files suitable for further design work, manufacturing, fabrication, 3D printing, documentation, or presentation.

Common deliverables include DWG, DXF, STEP, STL and PDF.

Have something that needs to be converted, recreated, modeled, or cleaned up? Send over the reference and let's get it into CAD.

Portfolio

Experience

Mechanical CAD Designer Protech Engineering Services · Freelance Mar 2021 – Dec 2022 1 yrs 9 mos Canada Worked at Protech Engineering Services as a Mechanical CAD Designer, developing mechanical parts and assemblies from sketches and design requirements. Most projects began with basic sketches, which required careful interpretation and adjustments before the designs could be developed further. After working through the initial concepts, I created the 3D models and detailed drawings needed for production and further development.
3D CAD Designer DesignWorks Engineering · Contract Jan 2020 – Feb 2021 1 yrs 1 mos Union City, CA, USA Worked at DesignWorks Engineering as a 3D CAD Designer, creating detailed models of mechanical components and product parts based on sketches, measurements, and existing references. The work involved developing the initial concepts into complete 3D designs, making changes when necessary, and preparing the finished models and drawings for fabrication and further development.
CAD Drafter Vertex Engineering Solutions · Contract Apr 2018 – Dec 2019 1 yrs 8 mos Irlam, Manchester, UK Worked at Vertex Engineering Solutions as a CAD Drafter, preparing and updating technical drawings based on engineers' sketches, measurements, and project requirements. The role involved developing detailed 2D drawings, making revisions during the design process, and ensuring that the final drawings were clear, accurate, and ready to be used for fabrication and documentation.

University Of Edinburgh Master of Arts (MA Hons), Business Studies and Finance, Upper Second-Class Honours (2:1) 2018 – 2022 Activities and Societies: Edinburgh University Trading & Investment Society, Peer Mentoring Scheme Four-year Scottish undergraduate program combining core principles of corporate finance, asset pricing, and business strategy with practical group project leadership.

Other experience

3D Mechanical Part Modeling Designed complex 2D technical drawings and 3D parametric models using Autodesk CAD software. Created detailed multi-part component assemblies, exploded views, and orthographic projections with strict tolerance requirements. Generated complete Bills of Materials (BOM) and schematic documentation for manufacturing workflows.
2D & 3D design and modelling, walkthrough Utilized Autodesk AutoCAD and Civil/Architectural tools to draft detailed 2D floor plans, elevation views, and site layouts. Applied precise scaling, dimensioning, and layer standardization to produce production-ready schematic sets. Developed 3D spatial visualizations to analyze room geometry and optimize structural layouts.
