www,celalettintoprak,com I design real products that get manufactured - not just 3D models. Manufacturing-ready CAD, prototyping, and Design for Manufacturing (DFM)-driven product development for industrial and consumer products. I’m an Engineer and Industrial Product Designer focused on manufacturing-driven product development. My background spans automotive, industrial, and consumer products, where I’ve worked as a Product Developer, Designer, and Technical Lead in production-oriented environments. I don’t approach projects as isolated design tasks. I approach them as systems that must survive prototyping, manufacturing, assembly, cost pressure, and real-world use. 📐 What You Can Expect Working With Me: - Clear, structured CAD suitable for iteration and production - Design decisions informed by manufacturing reality - Practical communication with engineers, suppliers, and manufacturers - Honest feasibility feedback (go / no-go when needed) - Designs meant to be tested, not just rendered 📐 Core Capabilities: - 3D CAD modeling (Siemens NX) - 2D technical drawings (AutoCAD Professional) - CNC, laser cutting, and sheet metal preparation - Injection molding–ready part design - Fixture, bracket, and assembly design - BOM creation and production planning support - Reverse engineering and scan-based modeling 📐 Injection Mold & Manufacturing Experience I have hands-on experience designing plastic injection molds and mold-ready parts, including projects for automotive and food-related products. ⚙️ I’m familiar with: - Injection molding–ready design, Core / cavity logic - Draft angles & wall thickness optimization - Parting lines and shut-off surfaces - Shrinkage and material behavior - Gate concepts (hot runner, valve gate) - Collaboration with mold makers and CNC shops - Design for Assembly (DFA), production validation - Engineering-driven product development - Long-term product roadmap support My focus is always on tool longevity, cycle time, surface quality, and cost efficiency. 📏 Typical Projects I Work On: - Automotive accessories and aftermarket products - Mechanically complex plastic or metal parts - Prototyping-heavy product development - Production validation before tooling - Redesigns for cost reduction or manufacturability - CAD clean-up and production conversion 📌 Primary CAD Tool: Siemens NX, AutoCAD and Geomagic Design X I work primarily in Siemens NX, which is widely used in high-end automotive and industrial manufacturing. I can deliver clean, fully editable STEP / STL / Parasolid files, and I regularly convert and work with SolidWorks, Fusion 360, Rhino, SketchUp, and scan-based data. If you use SolidWorks or another CAD system, this is not a limitation — deliverables are always production-ready and compatible. 📌 If you need more than a modeler—someone who understands how products are actually built and scaled—I can support your project from concept to production readiness.

I'm an Aerospace Engineer, with expertise in aircraft (UAV) deisgn, CAD , aerodynamic analysis (CFD), hardware integration, Ardupilot/PX4 firmware, developing custom GNC (Guidance Naviagation & Control) systems, Rapsberry Pi, Jetson nano, STM32, etc. About my job: I am serving as a Cheif Technology Officer at Alates Aerospace, which is UAV manufacturing firm located in Turkey. We provide assistance in all kind of Aerospace designs and firmware development. We handle projects ranging from UAV design, aerodynamic analysis, CFD, autopilot development, Guidance, Navigation, Control systems, 3D CAD modeling, prototype development and upto flight testing. We bring a professional team (ALATES) for your projects. ------------------------------------------------------------------------------------------------------------------- WHAT WE'VE BUILT & DEPLOYED: ALES-2 eVTOL | Hybrid QuadPlane Full electronic integration and flight testing of our hybrid VTOL aircraft. Configured autopilot for seamless transition between hover and fixed-wing flight, tuned PID controllers, calibrated sensors, and validated failsafe systems through progressive flight test campaigns. ALES NAV-2 | Satellite Telemetry System Real-time global tracking system tested on BELL 429 and Mi-8 helicopters for Turkey's General Directorate of Forestry. I integrated RockREMOTE Mini OEM (Iridium Certus 100) with Raspberry Pi, developed Python firmware for GPS telemetry with sub-second latency, and implemented cascading time synchronization, automatic modem recovery, and CloudLoop IoT integration. Now operational for BVLOS UAV missions, marine vessels, and submarine communications. ALES NAV-1 | Cost-Effective Satellite Tracker Budget-friendly tracking solution using RockBLOCK 9603 (Iridium SBD) — also deployed on forestry helicopters. Designed for long-duration missions with 45-second+ transmission intervals, reducing airtime costs while maintaining reliable global coverage. ------------------------------------------------------------------------------------------------------------------ WHY WORK WITH ME ✔ Real deployments — Our systems fly on government helicopters, not just simulation ✔ End-to-end capability — Design, build, integrate, test, deploy ✔ Professional team — Alates Aerospace engineers available for larger projects ✔ Hands-on experience — I tune PIDs in the field, not just in papers ✔ Clear communication — Video calls, progress demos, documentation included I prefer to start projects with a video call to understand your requirements and show you our previous work. Let's build something that flies. Syed Yasir CTO, Alates Aerospace Turkey
