Hello, I’m Dr. Ajeet Kumar Bhatia, a PhD in Control Theory & Control Engineering with 10+ years of hands-on experience in embedded systems, electronics design, control algorithms, and product-level engineering. I currently work as a Lead Engineer in a major automotive research and development environment, where I design and deliver production-grade embedded software and hardware solutions. Alongside this, I have been an active freelancer for several years, successfully completing 70+ engineering projects for international clients across embedded systems, PCB design, IoT, and control applications. My strength lies in combining deep theoretical expertise with practical engineering execution—from early concept and system architecture to implementation, debugging, validation, and documentation. I am comfortable working on both software and hardware, and I understand how real-world constraints (timing, power, cost, manufacturability, reliability) shape good engineering decisions. Key Expertise =========== - Embedded Systems & Firmware Development * C / C++, AUTOSAR (CP & AP), Complex Device Drivers * ESP32, ARM, Renesas RH850, Infineon Traveo, AVR, SAMD - Electronics & PCB Design * Schematic design, multilayer PCB layout, prototyping, testing * Altium Designer, Eagle, Proteus, LTspice - Control Systems & Algorithms * Advanced control, estimation, observer design * MATLAB / SIMULINK - Automotive, IoT & Industrial Systems * CAN, LIN, FlexRay, Ethernet, SPI, I²C, UART, MQTT - Debugging, Validation & Documentation * Hardware bring-up, system debugging, test planning * Technical reports, design documentation, presentations Why Clients Work With Me ===================== - PhD-level engineering depth with real product experience - Clear communication and structured problem-solving - Strong attention to reliability, maintainability, and performance - Proven ability to deliver complex technical work on time - Experience working with global clients and cross-functional teams I am open to short-term tasks, full prototype development, and long-term technical collaboration. Work samples and project details can be shared upon request. If you’re looking for a senior embedded & electronics engineer who understands both theory and real-world implementation, I’d be glad to help.

I can turn your project or an idea into reality, from conceptual design to building a working prototype and a small production run if needed. I specialize in: - Computer Vision research and development - Machine Vision system integration - Algorithm development - High performance implementation of image processing and computational geometry algorithms in C++ and Python - Robotics and mechatronics prototyping - Embedded systems prototyping

If it blinks, moves, or talks to the cloud I've probably built it. I’m an Embedded Systems Engineer and PCB Design Specialist with hands on experience turning complex ideas into realworld prototypes. Whether it's IoT devices, automation systems, or smart hardware, I design the circuits, write the firmware, and build the boards all under one roof. From the first spark of an idea to a fully functional, connected prototype, I help startups, makers, and engineers bring hardware to life. What I Do Best: PCB Design using EasyEDA Pro, KiCad, and Altium Microcontroller Programming for ESP32, Arduino (Nano, Uno, Mega), and Raspberry Pi 4B / CM4 Hardware Prototyping from schematic to soldered and tested boards IoT Integration using WiFi, BLE, MQTT, HTTP, and sensor data collection Writing clean, efficient code using Arduino IDE and Thonny I Specialize In: Rapid prototyping for smart devices Sensor interfacing and real-time control Low power and compact PCB solutions IoT product development with cloud connectivity Why Clients Hire Me: End to end development (design + code + prototype) Clear communication and milestone tracking Fast turnaround without sacrificing quality I treat every project like my own product Let’s build something smart, fast, and powerful — together.

I have over 22 years of experience working and consulting for tech companies in Silicon Valley. Every technical challenge that I had overcome assured me that with the right frame of mind, I could accomplish anything. Engineering is also my hobby, and I have been doing it since before high school. I was born with a soldering iron in one hand and writing code with the other. I designed the hardware for over 100 projects, most of them being sold today. Some notable ones are Snapchat Spectacles (designed most of the electronics and PCB layout), Thornwave Labs' Bluetooth DC Power Meter (PowerMon) and all the other projects on the webpage, various RF modules (RN-171, RN4020, RN52), and development boards designed while working at Microchip. I also created production testers, lots of C/C++ programming, and firmware design. What I can do for you? --------------------------- High Level: project management, research. I am very experienced with hardware design and firmware, which allows me to integrate them more efficiently. Hardware: circuit design, component selection, electrical schematic, PCB payout. I am using Altium Designer. I will provide you with everything you need to go to manufacturing: Gerber files, NC drill, pick and place, assembly diagrams, 3D prints, 3D STEP model, and electrical schematics as well as offer support after the project is completed. I have experience with analog and digital design, RF, high-speed design, microcontrollers, highly complex boards, LCDs. I can run Spice simulations as well. I worked with various technologies and protocols: SPI, I2C, UART, USB, CAN, RS-485, Ethernet, Bluetooth, WiFi, and so on. Prototyping: I will manufacture the prototypes at a much lower cost than average. Over the years, I have developed working relationships with manufacturers in China, hence the cost-saving. I also have a lot of equipment: multimeters, oscilloscope, logic analyzer, vector network analyzer, USB protocol analyzer, power supplies, digital electronic load, soldering equipment, computers, and so on... Certifications: I can assist and oversee the certification process for FCC, IC, and others. Firmware development: I have 24+ years of experience coding in C/C++ and 20 years of firmware development. I can architect and develop your firmware from the ground up. I am exceptionally versed in the ARM Cortex line of microcontrollers: STM32 and Nordic. I will provide you with production-quality firmware. I know the ST and the Nordic microcontrollers like the back of my hand. I can get firmware done very quickly and efficiently for these chips. Software development: Basic tools running in Linux/Windows/Mac, basic GUIs. I can develop all the software tools you need for debugging, testing, and manufacturing. Manufacturing: If your project reaches this phase, I can offer contract manufacturing services. I will be delivering your finished product, ready to sell. The rate I displayed is an average number. It can vary up or down based on the complexity of the project. My rate reflects the experience and knowledge I have. I am good at what I do. Also, keep in mind that I will not bill you for hours like lawyers do for the time they spend in the shower thinking about the project. I will bill you only for the hours I spend advancing the project in a meaningful way.
