The expensive problems in product development rarely look serious in a render. They appear later, when parts do not assemble correctly, tolerances stack up, seals fail, tooling costs rise, or a promising prototype cannot be manufactured consistently.
We are a mechanical design and product development team focused on preventing those problems early. We turn concepts, existing prototypes, sketches, and incomplete CAD into practical, manufacturing-ready products with clear engineering logic behind every important decision.
Our work is centered on mechanical products, enclosures, mechanisms, injection-molded plastic parts, sheet-metal products, CNC components, and multi-part assemblies. Depending on the project, we support product architecture, SolidWorks CAD, interface and tolerance design, material and manufacturing-process selection, DFM/DFA, engineering drawings, BOMs, prototype preparation, and targeted FEA when it is needed to validate a real design decision.
Recent completed projects include an environmental sensor enclosure developed around an existing PCB, connectors, sealing, and serviceability requirements; a 1-liter PET bottle indexing feature designed around labeling and production constraints; and a technical engineering review of a premium espresso machine to identify mechanical, assembly, service, and manufacturing risks before the next development stage.
Clients do not work with us simply to receive a 3D model. They work with us to make better decisions before committing money to prototypes, tooling, or production. We identify missing requirements, weak interfaces, likely failure points, and manufacturing conflicts early, then compare practical options against performance, cost, assembly, maintenance, and supplier capability.
Each project has one clear communication path, while the appropriate specialists are involved only where their expertise adds value. This gives you the depth of a coordinated engineering team without the confusion of managing several disconnected freelancers.
We are best suited to serious product-development projects where the design must do more than look convincing. It must be buildable, testable, serviceable, and ready for the next real step.
Share your current concept, CAD files, sketches, prototype photos, and manufacturing goals. We will help you define the safest and most practical route from the current stage to a production-ready design.

I help you avoid that.
I'm a Mechanical Design Engineer specializing in SolidWorks, and I take products through
the full journey: ๐๐ฑ๐ฒ๐ฎ โ 3๐ ๐๐๐ ๐ ๐ผ๐ฑ๐ฒ๐น โ ๐ฃ๐ฟ๐ผ๐๐ผ๐๐๐ฝ๐ฒ โ ๐ ๐ฎ๐ป๐๐ณ๐ฎ๐ฐ๐๐๐ฟ๐ถ๐ป๐ด-๐ฅ๐ฒ๐ฎ๐ฑ๐ ๐๐ฒ๐๐ถ๐ด๐ป. I've also
managed CAD design and drafting on the manufacturer's side, so I know exactly what a
production floor, a machine shop, or a molder needs to see on a drawing before they'll
trust it enough to quote it.
Whether you're a startup with a sketch on a napkin, a business scaling an existing
product, or an inventor with an idea you've never told anyone about, I can take it from
concept to something a factory can actually build.
๐๐๐๐ ๐ ๐๐:
โ 3D CAD Modeling (SolidWorks) - Clean, parametric, built to be manufactured, not just rendered
โ Product Design for New Ideas - Sketches, references, or a rough description turned into CAD
โ Design for Manufacturing (DFM) - Catching the mistakes before they cost you a bad mold or a rejected batch
โ 2D Technical Drawings - GD&T, tolerances, BOMs, weld callouts, ready for any shop floor
โ Sheet Metal Design - Flat patterns, production drawings, DXF for laser/CNC
โ Prototyping Support - Print-ready STEP/STL files for 3D printing or first-run testing
โ Reverse Engineering - Turning an existing part or physical sample into full CAD
โ CAD Design & Drafting Management - I can run this workflow for manufacturers too, not just individual projects
WHY WORK WITH ME
Most freelancers hand you a pretty file. I hand you a file that survives contact with a
real manufacturer, because I've sat on that side of the table too. I ask the questions a
machinist or molder would ask before you ever send it out for quotes โ so you're not the
one finding out something's wrong after you've paid for tooling.
๐๐๐ ๐ ๐๐๐๐:
Send me your idea, a sketch, a photo, a reference product, or just a description. I'll
scope it, flag any manufacturing risks early, and walk you through the process from first
model to final drawing set. Clear communication, real files (native SolidWorks + STEP/PDF),
and no surprises at the end.
Have a product idea sitting on your phone or a napkin somewhere? Send me a message.
let's find out what it takes to actually build it.

๐ MY PROCESS: CONCEPT โ CAD โ PROTOTYPE โ PRODUCTION
1. Concept & Feasibility
I review your idea, sketch, or existing design and flag manufacturing risks before any CAD begins.
โ Result: a clear, cost-aware roadmap โ no wasted design hours.
2. Engineering & CAD Modeling
Manufacturing-ready SolidWorks/Fusion 360 models โ correct draft angles, wall thickness, tolerances, and assembly logic that factories can quote and build without back-and-forth.
โ Result: production-ready files, zero confusion at the factory.
3. Prototyping & Validation
3D-printed prototypes to test fit, function, and durability before you commit to tooling.
โ Result: a validated design and lower financial risk.
4. Production & Scaling
Complete technical drawings, GD&T, tolerance analysis, BOM, and manufacturing documentation for injection molding, sheet metal, or CNC production.
โ Result: smooth handoff to manufacturers, confident scaling.

As a Manufacturing Engineer, my duties are to design not only the parts that customers need, but also, help optimize the part design, prototype the design, create detailed blueprints for manufacturing and even design the injection mold tools that will produce the parts in mass.
After the design is started, I collect all information to assist with the part designing process. I create the preliminary part design then, work with the customers to make any adjustments that may be needed.
Through this time I 3d print prototypes if needed to send to the client. We then have a final review to make sure the design is functioning and cost effective for manufacturing processes.
Once the design is approved, I can design the injection mold tool if needed. I can help to source manufacturing and offer consulting for any questions through the entire process.
For some customers I program the CNC mills and lathes in order to produce every component needed to make the parts or injection mold tools.
At my full time job I work doing all of the same things from above, We design parts, and injection molds, build the molds then run them all in house.
After the first run we verify all dimensions are within tolerance make any changes needed then start production.
I have designed many molds that are being used for 5-10 year+ contracts making automotive parts, aerospace, military and defense, government contracts, medical etc.
I have 15 years of experience in 3d modeling, concept design, part design, 3d printing and rapid prototyping, CNC programming and much more.
I'm proficient in Solidworks, AutoCAD, Camworks, Fusion 360, Inventor and many other programs used to design parts.
I'm taking online classes for Manufacturing Engineering at Sinclair Community College in my spare time.
I have the following certifications for SolidWorks and Camworks:
Associate- Mechanical Design (CSWA)
Associate- Additive Manufacturing (CSWA-AM)
Professional- Mechanical Design (CSWP)
Professional- Advanced Mold Making (CSWP-AMM)
Professional- Advanced Surfacing (CSWP-AS)
Professional- Advanced Drawing Tools (CSWP-DT)
14 Camworks certifications
112 SolidWorks certifications (continuing education from 2010-present)
If I can help assist in any CAD designs, product designs, CNC programming,3d printing/ prototyping, product rendering, manufacturing, sourcing, reverse engineering, injection mold design, 3d printing or anything else please reach out as I'd love to see if I can help.

Mechanical and Product design engineer. I've delivered CAD, DFM, and production-ready design across consumer electronics, furniture, automotive mechanisms, injection-molded parts, and industrial equipment.
With 8+ years of experience in SolidWorks and industry-standard tools, Iโve worked with startups and engineering teams to develop consumer products, mechanical systems, and industrial designs from concept to manufacturable output.
๐ง Where I focus:
Product design: concept sketches through fully detailed, manufacturable 3D models
Mechanical design and CAD modeling: parts, assemblies, mechanisms, enclosures
Design for Manufacturing (DFM): injection molding, sheet metal, and machined parts
Technical drawings, GD&T, and exploded assembly documentation
Reverse engineering: physical part or scan to parametric CAD
Rapid prototyping support before tooling commitment
Photorealistic rendering for pitch decks and product visualization
๐ฏ How I work:
It usually starts with a short call, what you're building and where it needs to end up. From there we move into design, and I keep you posted as it develops instead of going quiet until it's finished. The process isn't rigid, a napkin sketch and a half-built CAD file need different starting points, so I adjust to wherever you're at.
๐ CAD stack:

Senior Industrial Designer with 8+ years of experience and a Sofeast factory + lab in Shenzhen behind me. I design IoT enclosures, wearables, consumer electronics, and rugged outdoor products from sketch to injection molding ready CAD, with DFM considered from day one.
The Sofeast difference (vs. solo freelancers):
Iโm not designing in a vacuum. Every CAD file I deliver is pressure tested against real factory constraints by Sofeastโs mechanical engineers, mold makers, and QA team. That means fewer surprises, smoother tooling feedback, and fewer revision rounds once production starts.
What I design:
โข IoT devices & wearables - compact enclosures, IP67/IP68 sealing, battery + PCB integration, snag free outdoor geometry, sensor pass throughs
โข Consumer electronics - earbuds, speakers, smart home products, beauty devices
โข Rugged, outdoor, livestock & medical related devices - drop resistant, UV stable, electrode integration
โข Furniture & sports equipment - ergonomic, multi material, fabrication friendly
โข Home goods, kitchen, pet products, and broader industrial design projects
What I deliver:
โข Concept sketches & ideation
โข 3D CAD (SolidWorks, Rhinoceros, Fusion 360) - parametric and easy to iterate
โข Production ready STEP files, 2D technical drawings, GD&T
โข DFM support - wall thickness, draft angles, gating, sink mark risk, material selection (ABS, PC, PP, POM, TPU)
โข Photorealistic renders (KeyShot, Vizcom, Midjourney) for pitches, listings, and crowdfunding
โข Tooling consultation with direct communication with Chinese mold makers
Why this matters when your design reaches manufacturing:
โข Wall thickness, draft angle, and gate placement are reviewed BEFORE tooling investment
โข Material recommendations are based on real manufacturing processes, not only datasheets
โข When factories push back on features or geometry, our bilingual team can communicate directly and solve issues faster
Manufacturing experience:
Plastic injection molding, sheet metal, CNC wood fabrication, die cut packaging, and more.
