Building Infrastructure for AI and Super Intelligence

Metaverse - Horizon OS team

• Driving design discussions and doing code reviews from time to time and give quality feedback to the engineers.

• Successfully transitioned in-app purchases from the legacy Horizon service to the advanced Oculus Controller Management Service (OCMS). This migration leveraged a more sophisticated infrastructure, significantly optimizing bandwidth, throughput, and I/O operations.

• Optimized download processes by implementing real-time checksum verification during downloads, leading to a 20% reduction in both download time and CPU credit usage.

• Seamlessly integrated the OCMS downloader with Superpack technology, resulting in faster download times and more efficient CPU credit usage.

• Developed and executed comprehensive end-to-end tests for network stability on Quest 2/3 devices. These tests ensured reliable performance even in challenging network conditions.

• Implementing semi-connected operation for raising faults based on the state of the connection to intersight cloud from appliance.

• Raising alerts if the system has not been upgraded for a certain duration of time.

• Implementing upgrade system for pushing upgrades to the appliance virtual machine from cloud.

• Implementing metadata upgrade system for services quickly without upgrading entire service.

• Wrote automation code for validating assist/airgap/connected upgrades and install using python and deployed it successfully on Jenkins.

. Implemented external syslog feature for exporting logs from appliance to an external syslog server.

. Working on the integration of Access Control Application with Integrity Services Engine.

. Migration of policy management for scalable groups, group based policies from fusion into cloud.

. Wrote python script for creating/deleting atomic counter policies on APIC and pushing it to leaf nodes for monitoring ongoing traffic.

. Optimizing the traceroute policy design by creating new summary mo’s and pushing them to the leaf nodes instead of whole tree.

. Troubleshooting false drops/excess when a new node gets resynced to the rest of the fabric.

. Wrote C++ code at the APIC level for pushing external IP policies to only those leafs that have an entry in the route table.

. Wrote C++ code for implementing traceroute policies for external IP addresses.

. Wrote python script for creating/deleting atomic counter policies for L4-L7 subnets between endpoints that are connected by firewall and load balancers.

. Implementing multi-tenant Atomic Counter/Traceroute policies

. Writing C++ code for implementing mac-based atomic counter rules for monitoring traffic between endpoints.

. Implementing traceroute policies for troubleshooting/monitoring traffic to an external ip address.

. Implementing atomic counter policies for counting data packets between two external ip addresses.
