Project: Liberty (CNX) – Next-Generation Configuration Platform for Aruba Central

• Designed and implemented YANG-based configuration models to standardize network configurations across Aruba platforms.
• Developed auto-generated REST APIs and GraphQL schemas for seamless integration between Central UI and backend services.
• Contributed to Global Configuration Service by modeling reusable configuration objects, enhancing centralized libraries.
• Implemented scope-aware configuration mapping, supporting multi-level hierarchy for improved scalability in enterprise environments.
• Enabled automation through API-first architecture, allowing programmatic configuration of network infrastructure.
• Ensured compatibility across heterogeneous devices with capability-aware schemas and validation processes before deployment.
• Collaborated with cross-functional teams to integrate YANG models with backend services and Central UI workflows.

• Supported new features in Network OS (Aruba OS-CX), leveraging centralized DB (OVSDB) to enhance system capabilities.
• Implemented keychain support for BGP TCP-AO functionality, improving security and reliability in network communications.
• Provided support for BGP TCP-AO protocol implementation.
• Resolved defects in L3/L2/ARP/subinterface/BGP TCP-AO/Rdiscd/portd, ensuring optimal performance and stability of network protocols.
• Defect fixes in Router discovery protocol, ipv6 Stateless Address AutoConfiguration
• Created and managed interfaces (Rop, Svi, Lag, loopback, subinterface) in kernel and centralized DB (OVSDB).
• Subinterface support for both merchant silicon as well as proprietary ASIC
• IP TCP MSS support

• Facilitated path MTU discovery for efficient data transmission
• Provided ICMP redirect support to optimize routing decisions
• Implemented IP unnumbered support for streamlined address management
• Developed TCP/UDP close port packet statistics for improved network monitoring
• Default svi creation with dhcp enabled on access platform
• Resolved issues in L3 addressing, routing, VLAN configurations, and CLI support

• Implemented SNMP protocol for chassis management module, enabling streamlined device management and monitoring.
• Supported chassis management module across multiple platforms (e.g. DELL4048T, AC5712) to ensure compatibility and enhance device management.
• Enhanced network troubleshooting capabilities by supporting ICMP MTU exceeded message.

• Developed automation scripts for chassis management module, streamlining operational processes.
• Implemented SNMP protocol for chassis management module, improving network monitoring capabilities.
• Collaborated with developers to troubleshoot and resolve software issues.
• Assisted in software testing and quality assurance processes.
• Documented testing procedures and results for future reference.
