I turn ideas into working hardware, fast. From first principles to factory-ready files, I design and build complete products: mechanisms, electronics, firmware, and test rigs that survive real-world use. Top Rated Plus, 100% Job Success, 2,000+ hours on multi-month R&D and product builds. What I do best -Robotics & Mechatronics: Motor/gearbox sizing, kinematics, control (PID/FOC), actuators & sensors, reliable motion paths -Embedded & PCB: STM32/ESP32/Arduino, C/C++, Altium/KiCad, bring-up, drivers, test firmware -Mechanical Design & DFM: SolidWorks/Fusion 360, tolerance stacks, materials, manufacturing drawings -Rapid Prototyping: 3D printing/CNC, bench fixtures, data-driven iteration, demo videos for stakeholders Typical outcomes -A first prototype in 2–6 weeks with the right trade-offs for speed vs. reliability -Clear, version-controlled DFM packages suppliers can quote without missing details -Repeatable test results (e.g., duty cycles, torque/temperature margins) you can build your roadmap on Industries I’ve delivered for -Humanoid & assistive robotics, consumer hardware/IoT, lab & test equipment, education/STEAM devices, environmental tech (atmospheric water & thermal systems), and special-purpose mechanisms. My process (no guesswork) -Discover – Align on goals, constraints, risks -Architect – Select mechanisms, electronics, and control approach with a risk map -Prototype – CAD + PCB + firmware; focused experiments answer the hard questions first -Validate – Instrumented tests, logs, and short videos; iterate on evidence -Handoff – Manufacturing drawings, BOM & alternates, bring-up notes, maintenance docs Deliverables you can expect -CAD & manufacturing drawings (GD&T, tolerances, exploded views) -Schematics, PCB layout, Gerbers, assembly notes, and test points -Firmware (C/C++), configuration files, and a bring-up checklist -BOM with supplier options (cost/lead time/alternates) -Test plans, data summaries, and short demo videos for decision-makers Tooling & stack -Autodesk Inventor/AutoCAD • Altium / KiCad • STM32 / ESP32 / Arduino • BLDC/servo control • Python for data & utilities • 3D printing/CNC protos • DFM/DFA How we’ll start Share your goal and constraints; I’ll reply with a lean prototype plan (milestones, timeline, and risks addressed up front). If you prefer, we can begin with a 60–90 min architecture call to de-risk your approach and lock specs. If you need a product developer who can own the path from concept to proof—and hand it to manufacturing cleanly—let’s talk.

I am a Mechatronics Engineer from Pakistan's top university, NUST. Also, I have a distinction in electronic engineering by winning the Robotics Competition at National Level which bears testimony to my skills. My services are predicated on your trust shown to me. Your work is my trust and I consider it to treat it as my own. Albeit, I am new here, but not new in the field. I have an experience of a decade and had been delivering services in various fields of robotics for 6 years. To assist my clients directly with an affordable budget by eliminating the middlemen, my services are live now. My services include: Designing! 1. PCB Designs 2. Schematics and Circuit Layouts 3. 3D CAD models with Blender (SOLIDWORKS, Catia) Electronics! 1. Sensor Integration and Instrumentation 2. Troubleshooting in Circuits 3. Customized Circuit Buildups 4. Coaching Coding! 1. Arduino Coding 2. iOT 3. Mobile Apps (Flutter) 4. Matlab 5. Programming Languages (JAVA, PYTHON, C++, ASSEMBLY) BIG MOVE!!! I have launched my own prototype company by the name of FAB TRONICS. It can be viewed on my website and linkedin page. The primary objective of kickstarting it is to grant our valuables clients an opportunity for physical prototypes and minimize the pain that they endure in contacting a constellation of actors while production. WHY you should Hire me? .... I eat food, not people's trust. What can you get from me? Impeccable work in a courteous environment Due to the economic super cycle, my rates are accommodating, and intend to garner more positive feedback rather than draining my clients economically. Feel free to contact me. Looking forward to a healthy business relationship.

Your production line stops. Your prototype fails FEA. Every hour of downtime costs you thousands.
