Hire the Best RF Design Professionals

I am a Mechatronics Engineer and a member of the CorexLabs Engineering Team, specializing in Embedded Systems and PCB Design. Engineering Approach At CorexLabs, we approach every project with a structured, problem-solving mindset. We analyze requirements deeply, optimize design decisions carefully, and build systems that are reliable, scalable, and production-ready — not just prototypes that “work once.” We believe engineering is not about assembling components, but about designing intelligent solutions to complex technical challenges. Core Expertise Custom PCB Design (2–4 Layers) Schematic & Hardware Architecture Firmware Development (Embedded C) STM32, ESP32, Arduino Platforms Analog & Digital Circuit Design Communication Protocols (UART, SPI, I2C) System Debugging & Optimization What You Can Expect ✔ Clear technical communication ✔ Logical design decisions ✔ Attention to detail ✔ Efficient, reliable, and well-documented solutions As part of CorexLabs, I collaborate within a focused engineering team to ensure every project benefits from combined hardware and firmware expertise — delivering solutions that are built right from the foundation.

I deeply despise engineering that only works on paper. With a PhD in Electronic and Automation Engineering, I don’t just build research experiments, I engineer robust, mass-production-ready hardware and firmware that survives the real world. If you are stuck in prototype purgatory or terrified of your next manufacturing run, I am here to get your product out of the lab and onto the factory floor. WHO I HELP Series A+ startups, ambitious SMBs, and R&D teams who need to stop iterating on breadboards and start manufacturing. WHAT I DELIVER Flawless hardware demands flawless firmware. I execute the full stack so you don't have to coordinate multiple freelancers: • Manufacturing-Ready Hardware: Custom PCB architecture, schematic capture, and layout. I don't just send you a schematic; I deliver a de-risked manufacturing package (Gerbers, resilient BOMs, DFM/DFT notes). • Bulletproof Firmware: Lean, scalable C/C++ (Bare-metal or RTOS like Zephyr/FreeRTOS) deployed on STM32, ESP32, and Nordic MCUs. • Secure Edge Connectivity: Stable RF telemetry (LoRaWAN, BLE, WiFi, Cellular NB-IoT) optimized for extreme low-power budgets. • Industrial Automation & Control: Complex motor control, analog sensor integration, and custom automated test fixtures (Python/LabVIEW) to ensure 100% production yield. MY UNFAIR ADVANTAGE • Zero Finger-Pointing: Because I design the board AND write the embedded code, there is no blame game between the hardware and software guys. I own the system architecture from end to end. • Total IP Ownership & NDA-Ready: You receive full ownership of the schematics, code repositories, and test scripts from day one. I operate under strict confidentiality, send over the NDA and let's get to work. • Documentation-First Factory Handoff: I don't just throw ZIP files over the wall. You get comprehensive architecture docs, build instructions, and direct manufacturing handoff support so your Contract Manufacturer (CM) knows exactly how to build and test your product. LET'S BUILD IT Stop wrestling with designs that won't scale. Message me with your core requirements (MCU preferences, power/enclosure constraints, target certs, and quantities) and let's map out your roadmap to production.
