I have very good experience in all these areas and can assist greatly in all aspects. hourly rate is too low for me, but I am bidding because the requirements are perfectly aligned with my skills and experiences and even beyond. I have my own well grown lab so that can help bringing up the designs, troubleshoot. if you have flexible budget for well experienced remote assistance, get back. we can work in partnership.

Having worked in the integration of AI systems and predictive ML models into various contexts, including within existing workflows and on edge devices for real-time decision making, I believe my expertise is up to the task at hand. Aside from my experience with AI, I have also spent significant time in designing and manufacturing IoT hardware, specifically in PCB design and firmware development for microcontrollers like the ESP32 and STM32 that are widely used in IoT projects. Not only have I worked in the design phase, but I also have hands-on experience with assembly and hardware testing as required by this project. I make use of tools such as oscilloscopes, logic analyzers and multimeters during different stages of hardware development for functional testing, debugging and validation — urging towards a more reliable final product. My familiarity with various communication protocols including UART, SPI, I2C CAN BLE Wi-Fi and MQTT proves an added advantage. I'm confident in my ability to meet project deadlines without compromising quality or reliability—values which align perfectly with what you're looking for in a long-term collaborator. In terms of pricing, I believe in offering competitive rates without compromise on quality or dependability. Given my experience across diverse areas of electrical engineering and IoT development, I am eager to bring my knowledge to bear on your multiple planned projects. Let's get talking!

@alluankit01

Hi, I can support your long-term electronics and IoT projects as an individual PCB designer and firmware developer, covering schematic design, PCB layout, firmware, BOM, Gerbers, prototype bring-up, debugging, and testing. The best solution is to first review each project’s requirements, enclosure limits, power needs, communication interfaces, and production goals. I’ll then design clean schematics, route reliable PCBs, select available components, prepare manufacturing files, and develop stable firmware for the chosen microcontroller. I’m comfortable with KiCad/Altium-style PCB design, ESP32, STM32, Arduino/AVR, ARM-based controllers, UART, SPI, I2C, CAN, BLE, Wi-Fi, LoRa, MQTT, firmware debugging, component selection, BOM preparation, SMT/THT assembly support, and hardware testing with multimeters, oscilloscopes, and logic analyzers. Deliverables can include: * Schematic and PCB layout * Gerber and drill files * BOM with part numbers * Pick-and-place files * Firmware source code * Prototype bring-up support * Testing and debugging notes * Complete documentation I’m available for ongoing collaboration and will focus on quality, clear communication, reliable deadlines, and competitive pricing without compromising the engineering work. Best regards Ankit

I read through your requirements, and honestly, this sounds like exactly the kind of long-term collaboration I enjoy — multiple projects, real hardware, and a team that values quality over quick fixes. Here's what I bring to this: → I've designed and shipped PCBs for products like a custom ESP32 air quality monitor and an ESP32 audio player, handling everything from schematic to firmware to production handoff → I work across STM32, ESP32, and AVR, with deep experience in UART, SPI, I2C, BLE, and Wi-Fi — so I can pick the right tool for each job → I handle PCB assembly and testing in-house, with an oscilloscope and logic analyzer on my bench for bring-up and debugging → I'm available to start immediately and can commit to a steady workflow for ongoing projects For this scope, I'd quote around 300 per hour. Happy to walk you through my portfolio and past work on a chat.

@ElecHamza
