Something isn't working the way it should, and you need to understand why. It may be a material that keeps failing in use. A molded component coming out warped even after changes at the factory. A competitor's product you need to understand from the inside out. Or a formulation that needs to reach a specific performance target without months of trial and error. These are the kinds of problems I work on. My background is in polymer engineering and chemical process engineering, with 8+ years of work across materials, formulation development, reverse engineering, manufacturing, and applied R&D. On Upwork, that represents $80K+ earned across 69 jobs and 1,639 hours. The work can start almost anywhere. Sometimes there is a physical sample but no reliable formulation. Sometimes the formulation exists, but the product is not performing as expected. And sometimes the material itself is fine while the real problem sits in processing, mold design, cooling, residual stress, geometry, additives, or manufacturing conditions. Finding that distinction early can save a lot of unnecessary testing and costly iterations. For reverse engineering, I work backwards from the product rather than relying on a single analytical result. Physical behavior, chemistry, manufacturing route, SDS/TDS information, patents and literature, analytical characterization, and realistic raw-material options all contribute to the picture. From there, the work can move into formulation development, laboratory trials, comparative testing, optimization, and scale-up. I also have access to a research laboratory and major material characterization equipment. I can handle sample preparation, analytical characterization, comparative testing, experimental planning, and interpretation of results alongside the engineering work. The important part is not simply running tests. It is knowing which tests are worth running and what question each one needs to answer. Depending on the problem, this can include FTIR, TGA, thermal analysis, mechanical testing, microscopy, rheological evaluation, or other appropriate methods. AREAS I WORK IN — Product formulation and reverse engineering — Polymers, plastics, coatings, adhesives, sealants & industrial formulations — Material selection, substitution & qualification — Laboratory testing & material characterization — Failure analysis & root-cause investigation — Injection molding defects, warpage, shrinkage & processing problems — Product durability, fatigue, creep & material performance — Polymer compounding, additives, fillers & property modification — Competitor product & comparative material analysis — Manufacturing troubleshooting & process optimization — Experimental design, prototyping & validation — R&D, scale-up & manufacturability / DFM — Raw-material identification, supplier evaluation & technical sourcing — Cost optimization & technical documentation MATERIALS Thermoplastics · Thermosets · Engineering plastics · Elastomers · Rubber compounds · Composites · Nanocomposites · Bio-based & biodegradable materials · Coatings · Adhesives · Sealants · Epoxies · Polyurethanes · Masterbatches · Resins · Fibers · Fillers · Pigments · Dyes · Plasticizers · Stabilizers · Compatibilizers · Functional additives PROCESSING & MANUFACTURING Injection molding · Extrusion · Blow molding · Thermoforming · Compression molding · Compounding · Pellet production · Polymer processing · Process design · Scale-up · Reactor design · Separation processes · Mass & energy balance · Process simulation · Cost estimation ENGINEERING TOOLS ANSYS Polyflow · Aspen Plus · Aspen HYSYS · Moldex3D / Moldflow · SolidWorks · AutoCAD · MATLAB · Minitab I also use AI-assisted analytical workflows where they genuinely add value — particularly for technical literature and patent screening, formulation research, analytical-data comparison, and narrowing candidate materials during reverse engineering. It is another engineering tool; chemistry, physical behavior, manufacturing reality, and laboratory evidence still have to support the conclusion. I've published two peer-reviewed papers as first author. That research background influences how I approach unclear technical problems: establish what is known, identify what is missing, design the right investigation, question results that don't make sense, and build a conclusion that can be defended. If you have a material, formulation, product, manufacturing, or reverse-engineering problem that needs to be understood, fixed, improved, or developed, feel free to reach out and tell me what you're working on. Cheers!

I help companies take existing CAD designs and make them manufacturing-ready. Clients bring me in when a product already exists but needs to be cleaned up, validated, optimized for DFM, or clearly documented for suppliers and production teams. I typically work on products that are past the concept stage and require senior-level CAD refinement, design validation, and technical clarity before manufacturing or scale-up. You’ll want to work with me if: • You have an existing CAD model that needs cleanup, validation, or restructuring • A design looks fine visually but isn’t ready for manufacturing • Suppliers are asking questions or pushing back on drawings • Assembly logic isn’t clear or documented • You need senior-level DFM feedback before tooling or production • Legacy parts or STL files need to be rebuilt properly My work typically includes: • CAD cleanup, validation, and optimization for manufacturing • DFM-driven design refinement • Reverse engineering from STL, scans, or legacy CAD • Assembly logic definition and exploded views • Manufacturing and installation documentation • Technical animations for assembly, training, and product explanation I usually work in a technical lead or senior contributor role, collaborating with internal engineers, manufacturers, and suppliers. I focus on well-defined, execution-driven projects where accuracy, clarity, and manufacturability matter. My goal is to reduce production risk, supplier confusion, and costly rework before manufacturing begins. I bring over 19 years of experience working with industrial and mechanical products in engineering-driven environments, including projects requiring high accuracy, traceability, and technical rigor. My background in aeronautical engineering brings a strong focus on structure, validation, and design discipline to every project. Tools: • CAD: CATIA V5, SolidWorks • Visualization: KeyShot • Documentation and Graphics: SolidWorks Composer, Adobe Illustrator, Adobe Photoshop
