  Embedded software lead

  Responsibilities: 1. IoT collection kiosk - This is a customer-online-order public collection kiosk for a UK retail giant. Involved in complete embedded software architecture in yocto, on Intel IoT hardware. Integration of software with third party hardware APIs. Technologies involve REST clients for server comms, enhanced security and encryption, design of QT-based frontend, design of parallel processing of multiple customers on one kiosk. Development on GCC/GDB, leading a team of 4 senior developers. Successfully interacted on on-site visit with client and third-party vendors for deployment of pilot phase of project. Architected several workarounds to overcome client infrastructure limitations.2. Pre-Silicon Validation of SoC Security IP - This is a client-based workload in which functionalities of security IP on chip, needs to be validated, using existing test programs in C/C++. Gained an inside knowledge of how client's security IP works and able to find and correct issues in current test steps and methodology. Gained insight into client's C++ testing framework and SoC emulation methods.3. openCL based memory test tool - This is a client-based graphics memory test tool using openCL. Acquired in-depth understanding of graphics memory arch and openCL to be able to advise client on the best methodology for memory testing. Development in C using VS2017 and openCL framework. Received recommendation for client, since the tool is able to achieve PCIe bus stress levels much higher than client's current tools. Show less
