Hire the Best Mechanical Designers in California

As a highly experienced Senior Mechanical Engineer with a track record spanning over 15 years, I have successfully navigated many different industrial domains. My mission is to leverage this wealth of engineering expertise to deliver premium consulting services, encompassing everything from design to creation of concept-to-manufacture schematic drawings, FEA analysis, and comprehensive Design for Manufacturability (DFM) insights. My proficiency extends to various SolidWorks certifications. With a proven ability to excel across a wide spectrum of industries, I invite potential clients to peruse my portfolio. I look forward to connecting with you and/or your company to understand your specific goals and collaborate on tailored solutions that will drive your success to new heights.

Hello, Let me introduce myself. I am a physics engineer, materials science, and I have more than 15 years of experience as a design engineer. I have extensive experience in detailed design and modeling of tools and equipment, tolerance, and dimensional analysis. Very proficient in CAD, specifically in SolidWorks (owner of a Premium and Simulation Pro), Fusion 360 experience as well. Selection of materials, production processes, and suppliers. Calculation of cost and production time. I have experience designing finished products and tools/molds for the mold injection process, systems for high vacuum/ high pressure, inert, and dangerous gases, reverse engineering, CFD, and FEA analysis. Customer-oriented - I try to be neutral and objective, I fully listen to the person's comments and reflect on my work at the same time, with this fresh new perspective coming from this person's viewpoint. I respect they took the time to give me feedback and value their opinion. My job as a designer is to identify and find valuable solutions that will better serve customers. Sincerely, Vitaly

Architectural + MEP designer creating permit-ready plans that get approvals in California. Need architectural plans that actually get approved? I help homeowners, developers, and contractors in California create permit-ready architectural and MEP plans, including ADUs, custom homes, remodels, and multi-family layouts. With 100% job success and deep knowledge of local codes, I deliver clear, coordinated drawings that make city review and contractor coordination easier. I specialize in: ADU design, residential construction documents, MEP coordination, and permit-oriented plans. Let’s discuss what you need and how I can help you get it done. Message me to schedule a quick project discussion.

I strive to produce perfect results upon request, and seek to add value with recommendations that would improve designs for both function and manufacturing. Currently, my services include: Conceptual/Industrial Design, Mechanical Design, 3D digitizing, (reverse engineering), 3D modeling, DATA Conversion from CAD to CAD, and 2D documentation. In addition to these engineering services, I also can offer you Rapid Prototype models, usually an SLA, FDM, or SLS modeling technique. All data is electronically transferred, backed up, and delivered in a wide variety of formats. Over the past 40 years, I've created household products, indoor and outdoor electronics enclosures, automotive parts, medical devices, industrial equipment, lighting fixtures, packaging, pet products, hydroponic components, jewelry, and more.

I have 25+ years experience as mechanical design engineer, starting as a draftsperson and working my way up to design engineer. With experience in many different industries, mainly in semiconductor and horticultural fields, I've amassed more than 10,000 hours in both Solidworks and Pro-E. I am currently beginning my own venture to provide high quality designs and prototypes for people and businesses in need of manufacturable, cost-efficient, and creative designs. My aim and goal is to build long term partnerships, so no job is insignificant or too small. I also have extensive experience in simulation modeling for FEA and I am versed in GD&T, design for manufacturing and assembly, and have worked with high power, high frequency, HID and LED lighting, and commercial horticulture products. I am also very experienced in technical product literature such as cutsheets, instructions, and test procedures. I have a lesser (but still complete) background in civil, structural and architectural drafting, and am willing and able to help with that kind of work as well. I own a small in-house 3D printer, so if prototypes are needed, that service is available. I am currently working in Solidworks, Autodesk Inventor, and AutoCAD, and am also proficient in the Microsoft Office Suite and Adobe products. As a holder of several design patents, and many years of experience, I believe that I can be a great asset and provider to anybody who seeks a freelance design/drafting/technical writing expert, and I look forward to getting the opportunity to work with you.
