About Sameer Sinha

With 17 years of robust technical expertise, I have honed my skills in system software development across a spectrum of domains including Compiler, Kernel (specifically AIX), Storage Device drivers, diagnostic firmware for storage adapters, Storage emulators, FICON (Fiber Channel Protocol), and Firmware development. My proficiency extends to adept project execution, navigating through the software development life-cycle, and addressing systemic development challenges inherent in complex projects. I am recognized for my problem-solving acumen, collaborative team spirit, and a penchant for innovation. My specialised competencies encompass AIX Kernel (RAS) Programming, ProbeVue compiler Development, languages like C and C++, mastery in POWER/PowerPC assembly, adeptness in Kernel debugging tools such as RISCWATCH, and expertise in Firmware and device drivers. Moreover, I possess a deep understanding of Fiber Channel protocol and Storage protocol Emulators. Highlights:* Experience in developing firmware for FIBER Channel protocol emulators.* Experience in device driver for Host Bus Adapter (QLogic/Marvel & Broadcom).* Experience in developing hardware diagnostic firmware for HBA adapters for FC Cards.*. Knowledge in VFIO driver.* Experience on Compiler, Kernel (AIX kernel) and dynamic tracing tool (ProbeVue) development.* Sound knowledge of C, C++, Power Assembly, Data Structures and Operating Systems.* Strong understanding of software development life cycle (FRS, Design, Coding & Unit Test-ing).* Strong and sophisticated debugging skills in User and Kernel space of AIX.* Analytical skills to reason out and solve Kernel crash Dumps issues in the kernel.* Experience on debugging tools (dbx, kdb, KDB, GDB, RISCWATCH).* Experience on programming/debugging skills at the Assembly level.* Throughout knowledge of PowerPc/Power architecture.* Throughout knowledge in QLogic 2600/2700 series FIBER CHANNEL HBA.* Throughout knowledge in Kernel area (Process & thread Management, Dynamic & Static tracing),* Experience in Oracle Java Virtual Machine (OJVM) development.* Deep understanding of computer architecture, microprocessor concepts (caches, buses, memory controllers, DMA, etc.).* Expert level knowledge and experience in system software design and operating system fundamentals * Validated leadership skills and strong ownership on past projects in an environment with complex software and hardware designs.* email : sameer0201@gmail.com
