Research projects: • CXL (new standard based on PCIe) memory device emulation: Linux Kernel, QEMU • Secondary storage (backup, archiving, disaster recovery, continuous protection, etc.): protection of VMs and Kubernetes PODs.C++/Python code running in the Kubernetes PODs. Interception of block device data transfers in the Linux kernel. • IoT Network Security (code run on the Linux OS in the user and kernel space) • Lightweight AI inference engine (Linux, Android, LiteOS) • CPU scheduler in the user space (on Linux OS)My responsibilities in the research projects included development of SW code and DevOps tasks (build scripts, GitLab, Jenkins, Docker, Linux server administration)

Main responsibilities: Boot Loaders, Linux Kernel, Linux RootFS, Software build and integration.Detailed description:• U-Boot porting and extension for custom embeded boards.• Linux platform support (bus configurations, device tree configuration and processing, interrupt handling, etc.).• Linux device drivers (MTD, IDE/ATA, MMC, SPI, I2C, GPIO, RTC, EEPROM, PHY/MDIO, Ethernet, etc.).• Linux Root File system creation and maintenance (integration and customization of community packages, integration of proprietary packages, customization of start-up scripts and configuration files, etc.).• User-space hardware access application interface design and implementation.• Release build system design and implementation.

• Embedded OS evaluation: VxWorks 6.0, Integrity 5.0, and Embedded Linux (MontaVista, TimeSys, LynuxWorks, WindRiver, and Debian).• Middleware solutions investigation and evaluation.• Data-path simulator requirements and high-level design.• AdvancedTCA platform (PICMG 3.X family standards based equipment) evaluation.• Proof of Concept Edge Router porting to the AdvancedTCA and Linux based platform.• High Availability (HA) solutions investigation and evaluation.• Implementation of High Availability (HA) for the Proof of Concept Edge Router.

• Embedded OS evaluation: LynxOS, OSE, Embedded Linux (HardHat Linux, Embedix, BlueCat, RTLinux), NetBSD.• VxWorks OS porting and supportBoard Support Packages (BSPs) for at least six different boards.The porting efforts included customization and development of Startup code (Assembly and “C” level), drivers for Network, Serial, PCMCIA, PCI bus, I2C bus, Timers, System clock, Interrupt controllers, Flash File System drivers, PCI and PCMCIA configuration libraries, etc.• Bootstrap programThis program supports menu driven user interface, multi-bank boot, booting of compressed images, file downloading from remote host to local file system, file system navigation, and debug facilities.• System level libraries and servicesOS abstraction library, MMU based Memory Protection library, Memory Management library, Records File Management library, various protocol stack and system crash debug facilities, etc.• High and low level hardware control software modulesManagement code for optical modules, switch fabric, Ethernet switch unit.• Software development infrastructureGraphical hierarchical project build system (Makefiles, TCL scripts).Version control system (ClearCase) integration and version build automation.• System tests automationTest running engine design and development (Java, Python).

• Development of DOS File System for VxWorks.• Development of network and storage device drivers for VxWorks RTOS.• Development of Reentrant (multi-instance) TELNET server.• Development of System Sanity Control library.• Porting of the WinDriver - PCI bus access library to VxWorks.• Remote and on-site support/consulting in the TCP/IP Networking, Kernel, Device Drivers and Development Tools areas.

• Adaptation of telephone line maintenance code to a new telephony protocol.• Design and implementation of inter-processor data exchange software module.
