About

I help businesses, startups, and inventors transform product ideas into functional, manufacturable designs using SolidWorks. My expertise includes 3D CAD modeling, mechanical product design, prototype development, and Design for Manufacturing (DFM).

I focus on creating accurate, production-ready models with attention to functionality, assembly, tolerances, and ease of manufacturing. Whether you need a concept developed from scratch, an existing design improved, or files prepared for 3D printing or injection molding, I deliver clean, organized, and editable CAD models.

I can provide native SolidWorks files, STEP, STL, and technical drawings & solutions that help move products from concept to prototype and ultimately into production. Send me a message with your sketch or requirements today to discuss how we can bring your idea to production!

Experience

Mechanical Product designer Independent Specialist · Freelance Jan 2026 – Present 7 mos Lagos, Nigeria I work with clients to turn initial product ideas into functional three dimensional models and prototypes ready for manufacturing. My work involves designing mechanical parts, creating clean files for three dimensional printing or injection molding, and making sure every piece fits together correctly before production begins. I focus on keeping communication clear so clients know exactly how their project is progressing at every step.
Consumer Product CAD Designer Global Design Studio · Contract Mar 2025 – Present 1 yrs 5 mos Austin, Texas, USA I collaborated with international product design teams to develop mechanical enclosures and plastic housings for daily consumer devices. My focus was on refining living hinges, snap fit joints, and internal mounting features while ensuring all models maintained consistent wall thickness and draft angles for injection molding.
Prototyping and DFM Specialist Hardware Innovation Lab · Freelance Aug 2024 – Feb 2026 1 yrs 6 mos London, United Kingdom I assisted hardware startups in converting early concept drawings into functional three dimensional print files and prototype models. I concentrated on verifying assembly clearances, optimizing structural integrity, and running initial fit tests to identify design flaws before clients committed to full scale manufacturing runs.
Mechanical Engineering Drafter Independent CAD Solutions · Self-employed Jan 2024 – Oct 2024 9 mos Toronto, Ontario, Canada I generated detailed technical layouts, assembly views, and production documentation for custom mechanical parts and enclosures. I ensured all files were delivered in native SolidWorks formats along with universal STEP and STL formats to allow smooth communication between clients and their manufacturing partners.

Education

Federal University of Technology Bachelor of Technology (B.Tech), Computer Aided Design & Manufacturing 2021 – 2025 Activities and Societies: Innovation Hub, Student Designers Association Studied product design workflows, three dimensional modeling, and design for manufacturing. Gained hands on experience developing technical drawings and functional prototype files for industrial applications.
University of Texas at Austin Bachelor of Science, Mechanical Engineering 2020 – 2024 Activities and Societies: American Society of Mechanical Engineers I focused on core mechanical engineering principles, three dimensional computer aided modeling, and material selection for manufacturing. My studies covered solid mechanics, prototype design, and functional assembly validation.
Austin Community College Associate of Applied Science, Computer Aided Design and Drafting 2018 – 2020 Activities and Societies: Design and Drafting Society I studied foundational mechanical drawing principles, computer aided design tools, and basic blueprint drafting. Coursework centered on learning essential modeling software and preparing preliminary physical layouts.

Other experience

Sheet Metal Layout and Structural CAD I designed custom sheet metal brackets, industrial enclosures, and mechanical framework assemblies tailored for precise laser cutting and CNC press brake bending. I focused on calculating accurate bend allowances, relief notches, and hardware insertion points to ensure flat pattern layouts translated seamlessly onto the factory floor. I collaborated directly with fabrication teams to ensure all technical drawings provided clear bending sequences and accurate hardware specifications.
Reverse Engineering and Physical Part Modeling I regularly took legacy physical parts, hand measured components, and physical prototypes with precise digital calipers to recreate fully editable parametric CAD models. My main objective was taking existing physical hardware that lacked original technical documentation and turning it into clean, fully editable SolidWorks native files. I focused on preserving critical mounting hole patterns, structural tolerances, and functional mating surfaces so clients could easily modify or mass produce their updated designs.
Rapid Prototyping and 3D Print Preparation I provided hands on file prep and optimization services for clients utilizing additive manufacturing and rapid prototyping technologies. I spent time analyzing raw CAD models to resolve non manifold geometries, fix surface gaps, and adjust dimensional tolerances to ensure parts mated perfectly right off the build plate. I routinely prepared STEP and STL files specifically formatted for high precision resin and fused deposition modeling printers, saving clients significant time and material costs during early design validation phases.
Plastic Enclosure Design and DFM I specialized in designing custom plastic housings, snap fit casings, and protective covers for electronics and consumer goods. My day to day focus was applying key design for manufacturing principles early in the CAD modeling stage. This included maintaining uniform wall thickness, adding appropriate draft angles for clean mold release, and designing internal mounting bosses for circuit boards. Working closely with tooling specialists allowed me to spot potential molding defects before files were finalized for production.
Hardware Startup Product Consulting I spent over a year working directly with early stage hardware founders and independent inventors to guide physical products from rough sketches into manufacturing ready CAD assets. My core responsibility was taking abstract ideas, evaluating their functional feasibility, and modeling detailed assemblies that balanced aesthetic design with real world production limits. I guided clients through material selection options, structural reinforcement choices, and component layout strategies so their initial physical prototypes were cheap to test and easy to refine.
