I have over 22 years of experience working and consulting for tech companies in Silicon Valley. Every technical challenge that I had overcome assured me that with the right frame of mind, I could accomplish anything. Engineering is also my hobby, and I have been doing it since before high school. I was born with a soldering iron in one hand and writing code with the other. I designed the hardware for over 100 projects, most of them being sold today. Some notable ones are Snapchat Spectacles (designed most of the electronics and PCB layout), Thornwave Labs' Bluetooth DC Power Meter (PowerMon) and all the other projects on the webpage, various RF modules (RN-171, RN4020, RN52), and development boards designed while working at Microchip. I also created production testers, lots of C/C++ programming, and firmware design. What I can do for you? --------------------------- High Level: project management, research. I am very experienced with hardware design and firmware, which allows me to integrate them more efficiently. Hardware: circuit design, component selection, electrical schematic, PCB payout. I am using Altium Designer. I will provide you with everything you need to go to manufacturing: Gerber files, NC drill, pick and place, assembly diagrams, 3D prints, 3D STEP model, and electrical schematics as well as offer support after the project is completed. I have experience with analog and digital design, RF, high-speed design, microcontrollers, highly complex boards, LCDs. I can run Spice simulations as well. I worked with various technologies and protocols: SPI, I2C, UART, USB, CAN, RS-485, Ethernet, Bluetooth, WiFi, and so on. Prototyping: I will manufacture the prototypes at a much lower cost than average. Over the years, I have developed working relationships with manufacturers in China, hence the cost-saving. I also have a lot of equipment: multimeters, oscilloscope, logic analyzer, vector network analyzer, USB protocol analyzer, power supplies, digital electronic load, soldering equipment, computers, and so on... Certifications: I can assist and oversee the certification process for FCC, IC, and others. Firmware development: I have 24+ years of experience coding in C/C++ and 20 years of firmware development. I can architect and develop your firmware from the ground up. I am exceptionally versed in the ARM Cortex line of microcontrollers: STM32 and Nordic. I will provide you with production-quality firmware. I know the ST and the Nordic microcontrollers like the back of my hand. I can get firmware done very quickly and efficiently for these chips. Software development: Basic tools running in Linux/Windows/Mac, basic GUIs. I can develop all the software tools you need for debugging, testing, and manufacturing. Manufacturing: If your project reaches this phase, I can offer contract manufacturing services. I will be delivering your finished product, ready to sell. The rate I displayed is an average number. It can vary up or down based on the complexity of the project. My rate reflects the experience and knowledge I have. I am good at what I do. Also, keep in mind that I will not bill you for hours like lawyers do for the time they spend in the shower thinking about the project. I will bill you only for the hours I spend advancing the project in a meaningful way.

I’m an FPGA & Embedded Systems Developer and RF Signal Processing Specialist helping engineering teams build high-performance, real-time digital signal processing (DSP) and radar/RF systems from the ground up. I don’t just write bare-metal C code or flash basic FPGA bitstreams. I help teams: ✔ Translate complex MATLAB algorithms into optimized FPGA/MCU architectures ✔ Develop high-speed RF signal chains for L, X, and Ku-band applications ✔ Implement advanced DSP algorithms (CFAR, Doppler, Pulse Compression) in real-time ✔ Optimize microcontroller firmware for low-latency sensor fusion and data acquisition ✔ Bridge the gap between hardware design and software execution 💡 𝙃𝙚𝙧𝙚’𝙨 𝙒𝙝𝙖𝙩 𝙄 𝙃𝙚𝙡𝙥 𝙏𝙚𝙖𝙢𝙨 𝙁𝙞𝙭 & 𝙎𝙘𝙖𝙡𝙚 If your signal processing or RF project feels: ❌ Bottlenecked by inefficient hardware-software data transfers ❌ Struggling with real-time latency in DSP algorithm execution ❌ Plagued by environmental noise or poor target isolation ❌ Lacking deterministic performance in RTOS or bare-metal environments ❌ Disconnected between theoretical MATLAB models and actual hardware deployment Then here’s how I help: ✔ **FPGA & SoC Development:** Design high-speed processing pipelines on Xilinx RFSoC and Zynq platforms (Vivado/Vitis), implementing AXI DMA, PS-PL integration, and high-speed ADC/DAC interfaces. ✔ **Advanced DSP Algorithm Implementation:** Deploy FIR/IIR filtering, FFT, DUC/DDC, Pulse Compression, Matched Filtering, Doppler Processing, and CFAR target detection directly in hardware and firmware. ✔ **Microcontroller Firmware (C/C++):** Develop robust, real-time firmware for STM32 (HAL, LL, DMA, RTOS), ESP32, and TI C66xx DSP processors for sensor integration, data acquisition, and control logic. ✔ **Radar & RF Signal Chain Development:** Build end-to-end signal chains for radar applications, including environmental noise suppression, threshold optimization, tracking stability, and sensor fusion. ✔ **Hardware Bring-up & Debugging:** Perform rigorous hardware bring-up, peripheral integration, and root-cause analysis using JTAG, oscilloscopes, and logic analyzers. ✔ **Communication Protocols & Data Streaming:** Implement high-speed data transfer (Ethernet, SRIO, DDR) and standard protocols (UART, SPI, I2C, CAN) with secure, structured data forwarding. 🚀 𝙒𝙝𝙮 𝙃𝙖𝙧𝙙𝙬𝙖𝙧𝙚 & 𝘿𝙚𝙛𝙚𝙣𝙨𝙚 𝘾𝙤𝙢𝙥𝙖𝙣𝙞𝙚𝙨 𝙃𝙞𝙧𝙚 𝙈𝙚 Because I focus on what most firmware developers ignore: 👉 System-level architecture, not just isolated code modules 👉 Real-time deterministic execution, not just "it works in simulation" 👉 Mathematical algorithm optimization, not just copying reference designs 👉 Hardware-software co-design, not treating FPGA and MCU as separate worlds 👉 Mission-critical reliability, not just hobbyist prototyping Most developers just complete tasks. I build scalable, high-performance DSP and RF systems that help engineering teams: ✔ Achieve ultra-low latency in signal processing pipelines ✔ Maximize FPGA resource utilization and MCU processing efficiency ✔ Accurately isolate targets and suppress complex environmental noise ✔ Seamlessly transition from MATLAB models to deployed hardware ✔ Ensure deterministic, real-time performance in defense and aerospace applications I’m comfortable owning the embedded and FPGA development process end-to-end: —from algorithm design and hardware architecture to RTL coding, C/C++ firmware development, hardware bring-up, and system-level verification. I also understand the modern RF and embedded environment: strict timing constraints, high-speed data throughput, rigorous debugging, and reliability-focused optimization. 🔑 𝘾𝙤𝙧𝙚 𝙀𝙭𝙥𝙚𝙧𝙩𝙞𝙨𝙚 FPGA Development | Embedded Systems | Digital Signal Processing (DSP) | RF Signal Processing | Microcontroller Programming | C/C++ Firmware | STM32 | ESP32 | Xilinx RFSoC | Zynq UltraScale+ | Verilog HDL | Vivado | Vitis | Radar Signal Chain | CFAR Target Detection | Doppler Processing | Pulse Compression | DUC/DDC | FIR/IIR Filtering | FFT | High-Speed ADC/DAC | Hardware Bring-up | RTOS |
