Up to 14 years of experiences in the embedded world through mobile devices, tablet, smartphone, enterprise and set top box. I have a large range of skills through design, development, integration, validation and support. I got a huge experience in development in C, C++, Java and Python in the embedded world and also work easily on Android, iOS, Linux and Windows operating system. In addition I got also expertise's in: - Software quality: Methodology and Process enabling and definition, scripting development for automatisation tests, stress, functional testing to validate requirements and also MTBF tests - Software Legacy : Licensing violation & conflicts, IP Plan and License definition, Build tree advices to avoid licensing issues and patent violation. I have also created my own company to mainly develop apps for Android and iOS market and start a range of apps Android only focused on gaming & education apps for kids. Side market also following SW development of tools, stacks, framework for embedded upon request and provide consulting to improve SW life cycle process This an overview of my knowledge feel free to contact for me details
During the last 4 years, I have worked as C/C++ developer of application software (simulation systems), kernel mode Windows/Linux drivers, and real-time applications for x86/MCS51/ARM-based devices. Also I have skills in GPS(GNSS)/GLONASS and inertial navigation systems. Good knowledge in network programming (have own simple implementation of TCP/IP stack).
As an experienced Linux developer, contributor to the Linux kernel and successful freelancer, its natural that C and C++ are my most favored tools; but when it comes to making something amazing I have the skills and always up to date know-how of the complex nuances and frameworks of the technological industry. If you need a stable and extensible software design with performance that leaves an option to scale to giant user bases, I am definitely the most valuable candidate.
I have 8 years experience in developing BSP and drivers for various embedded operating systems such as Linux, Android, and Windows Embedded Compact. I am familiar with various hardware platforms, mostly ARM based, such as processors from Freescale, Texas Instruments, NXP, Altera, Xilinx, and others... I have a deep knowledge of the Linux kernel internals, and give Linux kernel trainings to embedded professionals on a regular basis. I also have a great knowledge of C/assembly low-level programming for µControllers running bare-metal. I have years long experience with controllers and buses such as I2C, SPI, UART, USB, PCIe, SDHC, etc... Most of all, I am passionate about everything embedded from small headless memory-constrained devices to high-end graphical tablet-like devices.
Over the last 15 years, I have developed a broad range of products using firmware, hardware and software in the telecommunications industry. My wide range of experience brings with it a full system level view and understanding of what needs to happen in order for a product to be successful. I'm seeking opportunities to apply my experience and adaptability to your problems and turn them into solutions.
For full-time work, I'm a talented, creative, schedule-oriented engineer with more than two decades of experience, proven leadership and technical abilities, and strong, friendly communication skills, I pursue challenging positions with innovative companies where I can continue realizing my full potential as a system designer and a software engineering innovator and leader. I can help you get your team project back on track. Or I can contribute, I never stopped being a developer. I'm a strong designer / coder / debugger and can adapt to new areas quickly. I'm a former Wind River Senior Member of Technical Staff, billed out at $235/hour, but available here for your fun and interesting software / firmware jobs without the Wind River overhead for much less. Latest: I spent 6 months doing python scripting at work, and a couple years on the side doing Windows Phone Applications (22 apps in the store).
