Hi, 1. I understand your ESP32-based 30A controller is already prototyped and operational, and now need an experienced engineer to finalize firmware. 2. I have strong experience in ESP32 firmware, embedded power-control systems, and hardware validation, including sensor monitoring, thermal protection, RTOS-based architectures, and debugging high-current electronics. 3. Relevant experience: * Developed ESP32 automatic audio bell PCB and Firmware. * Worked on Smart Energy Meter with DLMS protocol. * Developed firmware for LoRA wireless irrigation controller. * Experience reviewing schematics, and high-current design. 4. My approach: a) Review Firmware tasks, logic etc and update accordingly. b) Hardware Review: component selection and schematic design, layout & thermal analysis c) Stress testing 5. Deliverables: * Clean, commented firmware source * Hardware review report with recommendations * Test/stability report 6. I am preferred freelancer with 5 star rating and repeat customers. Let's connect to discuss and finalize timeline. Regards, Vishal

Hello, Your project fits very well with my background in ESP32-based control systems, power electronics, and high-current PCB design. I have experience working on embedded systems involving power management, thermal protection, monitoring, and production-ready PCB validation, including multi-layer boards and high-current routing. I can help you complete the remaining stages of the project: • Firmware development using ESP-IDF or Arduino framework • Power control and protection logic implementation • Thermal and current monitoring integration • Stress testing and debugging under 30A load conditions • RTOS and memory optimization • Error logging and stability improvements • Final hardware schematic and PCB review, including power traces and measurement circuits I can also review the existing Altium files, BOM, Gerbers, and source code to verify that the design is safe, manufacturable, and reliable before any PCB respin. My focus is always on delivering stable and production-ready results with clear documentation, commented code, and detailed feedback from testing. I would be glad to discuss the current prototype status and help finalize the system successfully. Best regards, Ahmed

Hi there, Taking over a high-power prototype and bringing it safely to the finish line is exactly the kind of end-to-end engineering I specialize in. Reviewing and optimizing for 30A continuous loads aligns perfectly with my daily work designing high-power motor controllers (1000W+) and complex power electronics. I work natively in Altium and can immediately audit your current hardware schematic, power trace widths, and thermal dissipation strategies to determine if a PCB re-spin is actually necessary. My Approach for this Rescue: Hardware Audit (Altium): Deep dive into the current layout, specifically validating the power paths, measurement circuits, and thermal reliefs. Firmware Review (ESP32): Audit the existing ESP-IDF/Arduino codebase. I will focus on optimizing the RTOS tasks, refining the thermal protection logic, and ensuring the bus communication is stable. 30A Stress Testing: Pushing the prototype to its limits to log thermal behavior and catch anomalies before moving to final production. I am ready to sign an NDA and review the current Altium source files and codebase. Let's schedule a quick chat to discuss the current state of the prototype and get this project across the finish line safely. Best regards, Akshay Rukade Founder, ZiroEDA

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have recently completed a power electronics project involving an ESP32 controller for managing high current, similar to your 30 A high-power controller, which worked seamlessly after iterative firmware and hardware refinement. From my experience, the most important aspect is ensuring robust firmware integration with hardware for stable and safe operation under full load. Approach: ⭕ I will thoroughly review your current Gerber files, BOM, Altium projects, and firmware source. ⭕ Finalize and optimize ESP-IDF or Arduino firmware focusing on power control, thermal protections, and bus communication. ⭕ Conduct detailed stress tests at 30 A current with thorough error logging and memory/RTOS optimization. ⭕ Perform careful final hardware layout validation focusing on power traces and measurement circuits. ⭕ Deliver well-commented code, full test reports, and detailed recommendations for production and potential PCB re-spin. ❓Could you please confirm if you prefer ESP-IDF or Arduino framework for firmware? ❓Is the current hardware design fully finalized or is some flexibility allowed for modifications? ❓Are there any specific logging or communication protocols you want implemented? I am confident in delivering a reliable, thoroughly tested product ready to meet your production requirements. Thanks for considering my proposal. Best regards, Nam

@Fady1PCB

Ciao, ​Ho analizzato il tuo progetto e mi interessa molto. Sono un progettista PCB con esperienza in sistemi embedded e circuiti ad alta velocità (uso abitualmente Altium Designer e KiCad). Capisco bene le criticità nel gestire 30 A su un ESP32: serve precisione assoluta per evitare problemi termici. ​Posso supportarti con: ​Audit Hardware: Revisione del layout su Altium per verificare tracce di potenza e thermal vias. ​Firmware: Ottimizzazione codice (ESP-IDF/Arduino) con logiche di protezione e RTOS. ​Testing Remoto: Io analizzo i file e ti fornisco il firmware; tu testi sul prototipo e io monitoro i log in tempo reale per validare il sistema. ​Suggerisco di dividere il lavoro in due Milestone: ​Revisione Hardware: Analisi Altium e report tecnico. ​Firmware e Test 30 A: Consegna codice e supporto al collaudo finale. ​Sono pronto a partire. Se mi invii i file, possiamo entrare subito nel dettaglio tecnico. ​Saluti, Fady
