I've been building embedded systems for over a decade, shipping products like BLE-enabled smart golf balls with 18-month coin-cell life and blockchain vending machines deployed at major airports. I handle the full stack myself — firmware, PCB design, 3D enclosure modeling, and prototype assembly — so there are no handoffs or delays between vendors. Your project gets a single point of accountability from concept to delivered hardware. I focus on getting a working prototype in your hands fast, not on endless discovery phases. I'll review your requirements, lock down the architecture, and start building immediately. If you need reliable firmware and hardware that works in the real world, I'm ready to deliver.

Hi, I can support the embedded hardware and firmware design for your variable-frequency, variable-voltage AC power supply. The best solution is to start with the correct inverter topology, MOSFET/IGBT and gate driver selection, sensing/protection circuits, isolated/control power supply, and PCB layout with high-voltage safety, EMI/EMC, creepage, grounding, and thermal considerations. Then I’ll develop Embedded C firmware for SPWM generation, frequency control from 0–100 Hz, voltage/amplitude control, SPI communication, calibration, and fault handling. I’m comfortable with power electronics, inverter/VFD-style designs, MCU firmware, SPI protocols, PWM/SPWM control, voltage/current sensing, PCB schematic/layout, BOM, Gerbers, and bring-up/testing documentation. Deliverables can include schematic, PCB layout, BOM, Gerbers, firmware source code, firmware notes, test procedure, and validation report. I’ll also keep the design practical for manufacturing and safe bench testing. Estimated timeline: after reviewing exact power/current rating and load type, I can provide a clear milestone plan and final budget. Best regards Ankit

Hi, there! I recently completed a project focused on designing an embedded system for a variable-frequency AC power supply, which involved creating both hardware and firmware solutions for efficient power conversion. This project required careful selection of components and precise control algorithms to ensure stable output across varying loads. In this endeavor, I implemented features such as a full-bridge inverter topology, PWM generation for output control, and a robust SPI interface for real-time adjustments. A significant challenge was achieving closed-loop voltage regulation while maintaining system stability, which I resolved through advanced control techniques and thorough testing of the feedback loop. I offer to bring my expertise in power electronics and embedded systems to develop a comprehensive solution tailored to your requirements. My unique approach includes detailed documentation and testing procedures to ensure a reliable and production-ready design, drawing from my extensive experience in similar projects.

I came across your project and I have to say, it looks like exactly the kind of challenge I enjoy solving. With six years of hands-on experience building embedded systems, I've worked on everything from custom PCB design to writing efficient firmware that actually holds up in real-world conditions. I recently shipped a solar-powered RFID water vending machine for a remote desert community, handling the full stack from circuit layout to the final firmware. I'd love to bring that same energy and attention to detail to your project, ensuring we get a working prototype in your hands quickly. I'm comfortable working across the entire product lifecycle, from initial concept and component selection through PCB layout, firmware development, and final testing. I believe clear communication is just as important as technical skill, so I'll keep you updated every step of the way. Let's turn your idea into something tangible.
