I am currently working as Software Architect in the Intel MODEM division under the Cellular Protocol Stack division. I am primarily engaged in the Technical lead role for the Layer-4/API layer of the Protocol stack and specializing in providing industry standard Cellular Protocol interface solution to the MODEM. I have a proficient and proven track record in the varied roles in my career at Intel from Senior software engineer to my current role as Software Architect/Member of Technical Staff. I have specialization in the following fields of the MODEM software development:
Standard C-language based Cellular Service APIs for both Circuit switched and Packet switched domains conforming to the latest 3GPP release standards.
Providing a unified and consistent abstraction towards MODEM that is agnostic to the underlying Radio Access Technology, allowing rapid adaptation of the HOST(Application Processor) and MODEM(Baseband) based applications.
Expertise in feature development like eMBMS, VoLTE, VoNR, e911, Supplementary services and SIM access.
MultiMODE and MultiSIM UE usecase handling and feature interactions in the MODEM for product variants and architectures line – DSDS(Dual SIM Dual Standby), DSDA(Dual SIM Dual Active), Hybrid – Mode DSDS with Single Receive Antenna support.
Domain controller Architecture with varied levels of delegation of functional responsibility between AP and Baseband. Interworking technologies – 3GPP, IMS, 3GPP2 and WiFi.
Data Connection Manager for a unified and agnostic API based approach for solving problems involving seamless data connection management across multiple RAT technologies.
The role also demands managing the team-members for the technical queries, close tracking of the development work packages and delivery management co-ordination within the component.
