• The Firmware tools we develop and maintain allow automatic system firmware update without any human intervention. The tools are targeted for all range of HP Integrity Servers supporting multiple OS platforms. The tools support online firmware update using the OS system call and offline firmware update using EFI interfaces. The firmware packages created are targeted for OS platforms Linux, OVMS, Windows and HP-UX. There are also offline installation medias (viz. bootable disk image). These all tools along with firmware binaries are released to HP Customers over the company website, downloadable from the company website.
• I started as a lead engineer in developing firmware deployment tools and solution package. Eventually entire program ownership and responsibilities were transitioned to me. My current responsibilities include the following activities:
• 1. Driving overall design and development of new firmware delivery tool solutions.
• 2. Supporting and maintaining the online and offline flasher utilities for legacy and next generation integrity servers.
• 3. Resolving technical issues, queries and escalations on these tools.
• 4. Managing the team's short/long-range schedule to adjust priorities within the team, publishing estimated and plan summaries to upper management.
• 5. Driving multiple initiatives (Lean Sigma) to reduce cycle time of the firmware delivery program.
• 6. Independently monitoring the upcoming workload and to host weekly firmware-delivery program meetings to discuss issues, plans, future roadmap and priorities.
• Later I was involved in Program Management of the HP Integrity Server Firmware Delivery which involved interacting with multiple partners and stakeholders, planning and work localization with global teams within HP. Also participated in supporting customer requests and planning program strategies and roadmap.
