  Roles:• Lead the projects from test PoV.• Collaborate with Arch, Development, and PLM teams about feature scoping and implementation.• Test planning and qualification as per product release cycles.• Design feature-specific test automation framework (class & modules structure and libraries) and guide team members in scripting. Language: Python, PytestProjects:1. G3x SPN2(c) switchponder card which houses Microchip's DIGI-G5 processor, Acacia's GL2 Bright Optics and Infinera's XR optics.• Mapping/muxing clients into OTUCn/FlexO structure (ITU-T G709.1, G798, etc.)• FCAPS (ITU-T G7710, G8201, Telcordia GR-2991-CORE, GR-1093-CORE, etc.) and Protection (ITU-T G873.1, G808.1)• Agile-based planning and execution2. G4x UCM4 aggregator card which houses Microchip's DIGI-G4 processor• Mapping/muxing clients into OTU4 structure (ITU-T G.798, G709, etc.)• FCAPS, YANG-based data modeling, and secure boot Show less Roles:• Test planning and qualification as per product release cycles and lead the feature test team• Collaborating with Arch, Development, and PLM teams about feature scoping and implementation• Design feature-specific test automation framework and scripts. Language: RAFFLE (proprietary)Projects:1. FCAPS for XT3300 transponder card (Ethernet over OFEC wrapper)• Ethernet Faults and performance management (IEEE 802.3ba)• Gen4 Line card with PM-16QAM/8QAM/QPSK/BPSK modulations and baud rates (33G/22G/17G)• Advance Optical features: Gain sharing, FEC Iterations, CD tolerance2. Multi-layer Recovery (MLR) features• Segment protection scheme where traffic is restored via an alternate path only around the faulted links and reuse bandwidth on the healthy links.• Service prioritization, where a high-priority service can pre-empt lower-priority services.• GMPLS restoration complementing legacy 1+1 protection (ITU-T G.808.1, G873.1) to enable the best resiliency with minimum bandwidth requirement.3. Automation:• Led the team in migrating the test libraries from proprietary RAFFLE language to a Python-based test framework. • Architected the class and module structures to get the maximum utility, scalability, and ease of adding new features.Demo:Demonstration of Ethernet FCAPS capabilities on XT3300 to Viasat.
