multithreaded application , data structure, design and analysis of algorithm,wireless sensor networks, mac layer ethrrnet driver tcp/ip protocol for automobile and industrial networks. software architecture, block chain,virtualization,autosar for autonomous cars.

Majorly worked on below areas:- I designed and developed the secure boot and corresponding changes in our loader as well as suggested few correction in OTP boot sequence which was part of chip vendorlike Broadcom, Mstar, Telechip (ongoing). - - TEE –Implemented TA application and client communication. Defined spec for client API interface for SVP.- Designed and implemented secure boot and secure boot firmware upgrade which is called BSECK in Broadcom design. This is to upgrade firmware which is traditionally locked and non upgradable once comes out of factory. with this mechanism we can still upgrade in field. This will also increase life and product endurance enhanced drastically without compromising security.- DRM design for widevine using VGDRM component used OEMCrypto License and content related operations such as sign/verify license and different type of key handling.- SVP specification definition for 4k content based on different security requirement defined by media labs, first using Broadcom SAGE processor.-TEE-TA implementation for VG DRM , This is POC along with Spec finalization, related to mode and restriction on TA. Who can call TA and security requirement defined by Netflix and media labs.- Good Understand of TEE TA architecture and different areas of Specification by GPD including Network component.- Understand thoroughly SVP recommendation and specification.- In past implemented RCU, FP-Segment display and NAND/Nor drivers in Linux.- As part of Driver team, fixed M2M,CM device related bug.- OTT profile bring with CISCO middleware with ST platform(palma).- First 4K TATA sky full s/w stack bring. - Designed and developed IP(Hybrid) loader which support IPMC,TFTP,Sat. - Worked on LHCR approval and KRFS for kernel hardening.- Good understanding of Linux internals and OS.- Silicon level Dhyrostone(core-Mark) and stack and memory leak profilling.- Broadcom Android TV Debugged some of HAL layer related to rcu keys ,Binder architecture.

I joined TEL as senior engineer. Since the date of joining I was working for PACE micro system. We were the first lot of couple of engineer who started pace ODC in India. We worked very hard to deliver software on time on quality and on margin.

I worked on bug fixing of STB migrated from openTv to NDS fusion OS middleware. I worked and debugged some of the bug related to SPM/SDM module with NDS.I was the lucky 3 engineer who was part of In house router development. We development complete cgi/dal layer along with worked on dhcp(WAN/LAN),upnp,httpd,sntp,dns,tinyproxy,urlfilter,CMS data model. I also worked/develop firmware down manager.Developed LED, Flash driver based on spec.We did lot of work on attached device detection(arp,arping,fcache). Made the auxiliary partition to store core and debug persistently across the boot.

Leading STB developement for the leading malaysian service provider.In the later part worked for airtel STB launch.I was working as Specialist in STB stack. I worked on all most all the layer starting from GUI(glade tool) to the pace own middleware Xcom for the european customer.We also developed xcom to ST and xcom to conexant driver abstraction layer.Worked mostly on the conax,Nagra,NDS bootloader. I majorly worked intially with Nagra bootloader and CA.
