@Mahihassi

With over a decade of professional experience in electronics, embedded systems, and firmware development, I am an ideal candidate to take your ESP32 project from its current stage to production-ready. My proficiency in platforms such as KiCad, Altium, EasyEDA, and Target will ensure thorough auditing and tidying up of the routing – addressing any critical signals meticulously in the gerber designs. My skills extend far beyond PCB layouts and I have successfully managed complete IoT product engineering. Your sensitivity regarding connectivity setup aligns perfectly with my skillset in wireless stacks including MQTT transport, and secure OTA hooks development. My expertise will ensure not only rock-solid provisioning but also additional features like reconnection logic. In addition, I have a strong grasp on mobile app development and ample expertise in MQTT integration- both crucial to this project. My software development background covering web and mobile applications will allow me to seamlessly wire the mobile app to live sensor data topics ensuring accurate data streaming without drops.

Hello, I have designed something similar for a past client. This project is a strong fit for my background. I’m a seasoned electronics hardware engineer (not a middleman), and I’ve delivered boards where mixed-signal design and power integrity were critical to success. especially combining ESP32-based control, multi-sensor expansion, into a single, production-ready PCB. What you’re really getting here isn’t just execution, it’s ownership. I take responsibility for delivering a clean, correct design so you don’t have to manage details or worry about downstream issues. You can visit my profile to see what my past clients have to say about my work If this sounds good fit, please start a conversation in the inbox using the chat button below. Abbas J SMB ElectroTech

Hi there! Prototype ESP32 systems often mostly work—until routing noise, reconnect edge cases, or MQTT drops show up in production. To resolve this, I’ll first harden the hardware by auditing power, RF, and signal-critical traces, then stabilize the firmware with deterministic provisioning, reconnect logic, TLS-secured MQTT, and OTA hooks that won’t brick devices. Once the device is solid, I’ll wire the app cleanly to MQTT topics so streaming is continuous and pairing is predictable. The goal is boring reliability—not another fragile prototype. ? This is exactly the kind of prototype-to-production cleanup I do. ? Audited and finalized ESP32 PCBs with RF, power, and signal-integrity fixes ? Delivered ESP32 firmware with long-running MQTT, TLS, reconnection, and OTA support ? Integrated mobile apps to live MQTT data streams for production deployments Happy to review your KiCad project and current firmware state to identify the highest-risk issues first. Top Rated with 100% job success, delivering systems that survive 48-hour soak tests and beyond. Best regards, Safeer Ahmad

Being an electrical engineer and data scientist with a proficiency in FPGA programming, digital systems, and PCB design gives me a unique edge to lead your project successfully. I have solid knowledge of ESP32 and its firmware development as I've worked in multiple projects taking prototypes to production. If reliability and stability are your concerns, let me assure you that I'm well-equipped for the task. My programming skills go hand-in-hand with my hardware expertise. Your requirements around MQTT setup, OTA hooks, and reconnection logic can all be addressed seamlessly using my skills in C/C++, Python, and automation tools like Google Apps Script. I'm precise and thorough with my designs — traits that are especially crucial when dealing with signal-critical nets as your circuit. Moreover, choosing me means getting access to not just proficiency in ESP32 or PCB designing but also an array of data analysis and visualization tools. This allows me to deliver on the app integration phase confidently by wiring your mobile app to live sensor data for real-time streaming, ensuring an intuitive pairing process. I believe my broad skill set could be invaluable for producing a comprehensive system you're envisioning.

Hey This is exactly the kind of prototype → production work I’ve handled before. I’ve got 7+ years of experience taking ESP32-based hardware from “it powers on” to fabrication-ready + stable firmware + app integration. I can audit your KiCad PCB, clean up routing (power, RF, sensitive nets), and deliver manufacturing-safe Gerbers. On firmware, I’m comfortable finishing ESP32 C/C++ stacks—robust Wi-Fi provisioning, reconnection logic, secure MQTT (TLS), and OTA hooks are all things I’ve implemented in real products. Once MQTT is solid, I’ll wire the mobile app to live topics so pairing and real-time data streaming are smooth and reliable. I’m fine working against bench-test acceptance criteria and zero warnings builds. Quick question: are you using a cloud MQTT broker (AWS IoT / EMQX / Mosquitto) or a custom one?
