Work History
Lead System Software Engineer / Software Architect
Aruba, a Hewlett Packard Enterprise Company
10.2021 - Current
- Subsystem Architecture: Serve as the acting architect for the centralized state-management and data-infrastructure layer of a high-performance network operating system.
- Middleware Infrastructure: Architected a high-scale messaging processor to provide low-latency event subscriptions and intra-node communication—functioning as the central integration bus for all distributed system services.
- API Framework Design: Designed a modular interface definition framework that serves as the system’s internal API contract, enabling standardized data exchange while reducing memory overhead for lower-tier hardware integration.
- Leadership & Mentorship: Lead technical decision-making and architectural reviews for global feature teams; mentor junior and senior engineers in systems thinking, delegating key deliverables while ensuring high-quality architectural alignment.
- Strategic Platform Enablement: Engineered the underlying data-management foundations (shadow-database sync and backup/restore mechanisms) that enabled hitless software upgrades, ensuring zero-downtime system transitions.
- Performance Engineering: Optimized state-distribution logic to handle over 1 million records in real-time, reducing system-wide distribution latency from minutes to milliseconds.
Senior System Software Engineer
Aruba, a Hewlett Packard Enterprise Company
08.2017 - 10.2021
- Infrastructure Leadership: Served as Tech Lead for the state replication and middleware infrastructure, transitioning from feature-specific development to broad oversight of core data-management components.
- Standardized Integration: Led the migration to a unified daemon template architecture, providing the foundational framework that optimized data convergence for high-scale (32k+ route) environments.
- Collaboration & Supportability: Acted as a primary Subject Matter Expert (SME) for global teams, providing technical guidance to resolve complex, system-level defects and leading the development of a diagnostic watchdog framework.
- Middleware State Management: Redesigned internal state machines within the replication layer to support new system-wide integration capabilities, including tunneling support and directed broadcast functionality.
System Software Engineer
Aruba, a Hewlett Packard Enterprise Company
04.2015 - 08.2017
- Infrastructure Development: Developed core C/C++ components for internal networking and traffic management daemons, focusing on efficient data handling and state-machine transitions.
- Feature Integration: Streamlined build processes for internal templates and drove the first "vertical slice" integration of new networking capabilities across the operating system.
- Automation & Testing: Engineered Python-based automated test harnesses and code-generation tools that accelerated the delivery of new system services and verified hardware-level data flows.
- Invention: Co-authored an invention disclosure for system-level optimization; consistently rated "Exceptional" for technical delivery, fast learning, and proactive problem-solving.
