Hello, We are interested in working on your ECG device project and believe our skills align well with your requirements. I will handle the PCB design and hardware development, while my team will focus on firmware, BLE communication, and real-time data processing. We have prior experience working on a BLE-based health monitoring node, where we implemented sensor interfacing, data acquisition (temperature and heart rate), and wireless transmission. This gives us a solid foundation for handling ECG signal acquisition and BLE-based communication. We are comfortable with: Low-noise analog front-end considerations ESP32-based system design Complete PCB design (schematic, layout, Gerber, BOM) Real-time BLE data transmission We understand this is a from-scratch, industry-level project, and we are confident in delivering a reliable prototype within your expected timeline. A couple of clarifications: Will firmware be developed entirely from scratch, or will any reference code be provided? How will testing and validation be managed in a remote setup? Needs Discussion

Hello, I have worked with ESP32 + BLE in real-time systems and strong experience in low-noise analog design, including sensor signal conditioning. For ECG, I would use a dedicated AFE (like ADS1292), proper grounding, shielding, filtering, and isolation to ensure clean signals. I use Altium and KiCad for professional, production-ready PCB design. I can handle full scope: schematic, PCB, firmware, and prototype support. Timeline: 4–6 weeks Budget: $2000 (milestone-based) I can share relevant PCB and embedded project samples. Looking forward to working together. Best regards, Engi Muhammad Imran
