Hi, I’m Debraj Das – a passionate Hardware Design Engineer with 3+ years of experience turning innovative ideas into reliable, market-ready electronic products. 🚀 From concept to certification, I specialize in designing high-performance PCBs and embedded systems that are not only production-ready but also cost-effective, reliable, and FCC-certified. Whether it’s a compact smart wearable or a robust industrial gateway, I ensure every design meets the highest standards in DFM, DFA, and DFT. 🔧 What I Bring to the Table: ✅ Expertise in KiCad (Primary), with experience in Altium and Eagle ✅ Designed and delivered boards for: Smart Ornaments IoT Gateways & Sensor Nodes Development Kits & Breakout Boards ✅ Deep understanding of communication protocols: UART, SPI, I2C, RS485, CSI, MIPI, HDMI, USB (up to 3.1), PoE ✅ Hands-on with microcontrollers and SoCs: Arduino, ESP32, Raspberry Pi Pico, STM32, Jetson Nano ✅ Skilled in Embedded C, RTOS, and Low-Power Designs ✅ Mechanical Integration using FreeCAD and Fusion 360 for enclosure and fit validation 💡 My design philosophy focuses on balancing performance, cost, and component availability—so your product isn't just functional, it’s feasible to scale and manufacture. Why Work With Me? I’m not just a designer—I’m a problem solver. I take pride in crafting elegant hardware solutions that are ready for real-world challenges. I communicate clearly, stick to deadlines, and always prioritize your vision. If you're building an innovative product and need a hands-on engineer who can bring both insight and execution, let's talk. Together, we can make your idea a standout success in the market.

I have skills for designing circuits around MCU, PCB, firmware by C language, mechanical design, applied consumer items. - C, Python, KiCad, Freecad - Target MCUs -> Raspberry Pi Pico, AVR, PIC, RX, RA, RL78

I am a versatile professional who specializes in project management and multidisciplinary design, bridging the gap between complex technical concepts and polished, market-ready products. My proven track record in project leadership includes directing a 7-member engineering team to develop the "SkinSense" machine learning application and securing national funding to manage the end-to-end execution of "CAPTURES," an IoT-based carbon capture initiative. Beyond overseeing technical workflows, I bring strong creative capabilities to the table; I utilize FreeCAD for practical 3D hardware design—such as custom electronic enclosures and component mounting—and leverage Adobe Creative Cloud (Photoshop, Premiere, After Effects) to produce compelling visual assets and brand strategies honed during my tenure as Creative Design Staff for IEEE. While my foundation is firmly rooted in electrical engineering with hands-on expertise in MATLAB, SIMULINK, and PLCs, my true strength lies in steering innovative solutions from concept to completion through proactive management and creative execution. If you are looking for a dedicated professional to oversee your tech project or design custom visual and 3D assets, let's discuss how we can collaborate to achieve your objectives.

i'm a design engineering manufacturing and a operator machinning CNC, my experience in a opertor cnc 1,5 years and a design engineering manifacturing in a 4 years and now, and my skill in a mechanic motorcycle starting from chilhood and now, and - software in a (solidworks, autocad, freecad, mastercam, and fusion) - part time project in a design engineering to finish - make a 3d model part and assembly and simulation in solidworks

Your prospects don't have time to decode jargon-heavy copy. They need to understand your value in seconds, not minutes. In 20+ years, I've helped numerous tech companies cut through the noise and speak directly to what their customers actually care about. I don't just write landing pages that convert, case studies that sell, and blog posts that engage. I own the process and build systems that continue to work long after I'm gone. I give you a strategy and a plan, and then I execute on it. Here is what my clients say about me: "He did an excellent job with the content but also proved to be far more versatile. He was able to coordinate website redesign, recommend experts, help with analytics, and so much more. He quickly became a trusted advisor and an essential member of the team. Can't recommend him highly enough." "I hired Alex for the first time years ago because I really liked the quality of his articles on his blog. He ended up doing several projects for me. Every time he delivered great results that required very little tweaking after the first draft. I will gladly work with him again in the future."

Hi! I'm Edit, a video editor and content creator with experience in studio and social media projects. I have filmed and edited short videos and clips, focusing on smooth cuts, basic color correction, and clear audio. I primarily use Adobe Premiere Pro and mobile editing apps to create clean and engaging content for platforms like Instagram, TikTok, and YouTube. I’m passionate about delivering polished videos on time and bringing ideas to life.

I am a Mechanical Engineering graduate specializing in 3D CAD design, robotics, UAV development, and industrial automation. I have hands-on experience creating mechanical components, assemblies, technical drawings, and product designs using Onshape and Freecad, with a strong focus on functionality, manufacturability, and precision. As Chief of Drone at Politeknik Manufaktur (Polman), I led the development of autonomous UAV systems using PX4 Autopilot, ROS 2 Humble, Gazebo, MAVLink, and Linux. My responsibilities included mechanical integration, system testing, troubleshooting, simulation, and project coordination. I also completed an industrial internship at PT Surya Sarana Dinamika (SSD), where I gained practical experience in machine assembly, industrial automation, and robotics. In addition to my technical background, I earned 1st and 2nd Place in the Indonesian Polytechnic English Championship for News Casting, demonstrating strong communication and presentation skills. I am committed to delivering accurate, reliable, and high-quality engineering solutions that meet client requirements and deadlines.
