Part-Time Engineering / Physics Assistant or Potential Partner -- 2

@ENG1mga

Hello, I’m a Mechanical / Mechatronics Engineer and I’d be very interested in working with you long-term, not just completing one design and leaving. I have worked on many real mechanical and mechatronic projects including delivery robots, robotic arms, drone mechanisms, automatic machines, mechanical ventilators, lifting mechanisms and other electromechanical systems. I can help with: - Physics and engineering feasibility - Mechanical/mechatronic design - CAD using SolidWorks & Fusion 360 - Component and material selection - ANSYS / COMSOL analysis when needed - Prototyping, testing and troubleshooting - Simplifying designs and reducing cost I also have access to a 3D printing and CNC workshop, so I can move from calculations and CAD to physical prototypes and testing. I’m interested in both part-time paid work and potentially a longer-term technical partnership if we work well together. You can see my previous work and reviews here: http://www.freelancer.com/u/ENG1mga I’d be happy to start with one of your current projects and see how we work together. Best regards, Mahmoud

Hi, Your approach strongly interests me because I enjoy working beyond simply delivering CAD files—I like understanding the underlying physics, evaluating feasibility, and turning early-stage concepts into functional prototypes. I’m a Mechanical Engineer with 5+ years of hands-on experience across mechanical design, mechatronics, electronics, embedded systems, robotics, automation, and product development. My experience includes SolidWorks/Fusion 360 CAD, mechanical systems, sensors, motors and motion control, PCB/electronics integration, embedded systems, and prototype development. I can contribute throughout the complete development cycle: - Analyze concepts and determine technical feasibility - Explain the relevant engineering principles and calculations - Develop mechanical/CAD designs and assemblies - Select materials, components, motors, sensors, and actuators - Integrate mechanical, electrical, and embedded systems - Perform engineering calculations and simulations where appropriate - Build, troubleshoot, and iterate prototypes - Document designs and test results for future development I’m particularly interested in robotics, automation, aerospace concepts, smart devices, electromechanical systems, and experimental technology, so the variety of projects you described is appealing to me. Best regards,

Hi, I'm Futras, a mechanical engineer with a mechanical engineer background and co-founder of Serko Engineering, a simulation and design consultancy. What caught my attention is that you want a collaborator who explains the engineering — not someone who hands over a file and leaves. That's exactly how I work. My core areas are mechanical design, FEA and multiphysics simulation (ANSYS, COMSOL), and CAD in SolidWorks. I've done drop-test impact studies, nonlinear contact and snap-fit locking mechanisms, thermo-mechanical analysis, and medical-device connectors — projects where the real work was deciding what's physically realistic before committing to a build. The work you describe is what I enjoy most: reasoning through the physics together, pressure-testing ideas, developing CAD, choosing components and materials, and iterating toward working prototypes. I'm patient about explaining the "why," and I learn from it too. I'm open to both paths — paid part-time to start, with genuine interest in a long-term partnership if the fit is right. For any equity arrangement, I'd want scope, IP, and ownership agreed in writing, as you noted. One honest note: I'm based in Lahore, so I'm strongest remotely on design, simulation, and component selection; physical build and test we'd coordinate on your side or via local fabrication. Happy to set up a call whenever suits you. — Futras Abbas

@MuhammadUzair16

Hi, I am an embedded systems engineer with over 16 years of experience turning early-stage ideas into practical consumer and industrial prototypes. My work has combined electronics, firmware, sensors, automation, motor control, component selection, mechanical integration, and hands-on testing, often taking products from concept through production. Your collaborative approach suits me well. I can help break each idea into requirements, explain the underlying physics and engineering tradeoffs, assess feasibility, develop system concepts and CAD-ready specifications, select materials and components, and support prototype build, bring-up, and testing. For the Smart Hot-Bar and other projects, I would begin with intended performance, constraints, risks, and simple calculations before committing time to detailed design. I am interested in paid part-time work and would be open to discussing a longer-term partnership after we have worked together and established a clear fit, with IP and responsibilities documented. I can accommodate approximately 22 hours weekly, including Monday and Wednesday collaboration. Which project would you like to evaluate first? I would be glad to discuss your ideas and the working arrangement in more detail.

@mahmoudralizadeh

Hi, this sounds more interesting than a typical “design this part” project because I’d actually enjoy being involved in the engineering process, not just producing CAD files. I’m a Mechanical Engineer with experience in SolidWorks, mechanical systems, mechanisms, electronics-related projects and prototype development. I’m comfortable researching a problem, checking whether an idea is physically realistic, designing it, and then improving it based on testing. I also like the fact that you want to understand the engineering behind the projects rather than simply outsourcing the work. I’m happy to explain the reasoning as we go. The part-time schedule works for me, and I’d be interested in building a longer-term working relationship if the first projects go well. If you have one project you’re currently deciding whether to pursue, send me the details. We can start there and see how we work together.

@maxscender

I can help you move from broad concepts to buildable prototypes by focusing on the practical engineering decisions that matter. I'll work directly with you to assess feasibility, handle the CAD and component selection, and explain the physics and trade-offs behind each choice so you can learn and make informed decisions. My focus is on establishing a clear, repeatable process for your Smart Hot-Bar system and other projects, ensuring each step is a solid foundation for the next. This approach is designed to support your long-term vision and build a technical partnership based on shared understanding and actual results.

I'm comfortable with rapid prototyping, component selection, and iterative testing workflows. I am interested in both part-time paid engagement and exploring a longer-term partnership arrangement, depending on project scope and how the collaboration develops. I would welcome learning more about your specific projects to assess where I can contribute most effectively.

@nichitav7

Hello, I am very interested in this opportunity because my experience covers **embedded electronics, PCB design, sensors, control systems, robotics, automation, power electronics, firmware, and prototype development**. I have worked on many multidisciplinary products where the job started from an early idea and required checking technical feasibility, selecting components, designing circuits and control systems, building prototypes, testing, debugging, and improving the design step by step. I am comfortable explaining the engineering and physics behind my decisions rather than simply delivering a finished design. I can help evaluate whether an idea is realistic, estimate performance, compare different approaches, and turn concepts into practical prototypes. I am also experienced in coordinating mechanical, electronic, and firmware development when a project requires several engineering disciplines. Your proposed **$20/hour part-time arrangement is acceptable**, and I am interested in both paid engineering work and, if we work well together, discussing a longer-term technical partnership for selected projects. I can start immediately and would be glad to begin by reviewing one of your current ideas and defining the most realistic development path. Best regards Nichita

@GridsmithLTD

Hello, I reviewed your requirements, and the core challenge is working alongside you as a technical problem solving partner rather than simply producing isolated CAD designs, especially across projects spanning mechanics, robotics, electronics, physics, and prototyping. I would approach each concept by first validating the underlying engineering assumptions, then supporting calculations, component selection, CAD development, prototype planning, testing, and clear explanations so technical decisions are practical and defensible. I have worked on multidisciplinary engineering, CAD, product development, and prototyping projects and can share relevant examples once we connect in chat.

@moha262

Hello! I understand you’re looking for a hands-on engineering/physics partner who can help evaluate your technology concepts, explain the underlying engineering, develop CAD and component selections, and progress ideas into practical prototypes across mechanical, mechatronics, robotics, electrical, and aerospace applications. I have experience with multidisciplinary engineering, mechanical design, CAD development, component/material selection, engineering calculations, and prototype-oriented problem solving, and I’m comfortable collaborating closely while explaining the technical reasoning behind each design decision. I can help move each concept through feasibility analysis, engineering calculations, preliminary design, CAD, component integration, prototype development, and testing while keeping the work organized for future development.

@Aaleen110

The hardest part of this job is filtering the wide range of technologies you are exploring down to the most viable mechanical and mechatronic implementations, so I will focus on CAD/CAM to prototype concepts and then simulate them using motion analysis tools to select materials and components that are technically realistic. I will build the Smart Hot-Bar system using SolidWorks for the CAD, selecting materials that can withstand the required temperatures and stresses, and also design the robotics components with a focus on Mechatronics, so the actuators and sensors work together efficiently. The most common failure for this kind of work is selecting components that don't integrate well or are not robust enough for the intended use, so I will cross-reference datasheets and also perform stress analysis in the CAD software before finalising designs. What are the specific operating temperature ranges and duty cycles for the Smart Hot-Bar system? I need the most critical project you want to tackle first, and once I have that, I will send back a structured proposal outlining the first phase of work. 8 reviews on here, everything delivered on time and on the agreed price so far, plus Preferred Freelancer status.
