Lead Firmware Engineer | 2020 - PresentIntelliSlot Communication Cards – Linux RTOS, sensor data communication cardsWorking remotely with teams based in Ohio, Texas, Florida and India to support two existing hardware platforms (Unity and RDU101) while developing a new one.• New development of an NXP i.MX 8M Yocto based IntelliSlot card. Convert proprietary components from SystemV to Systemd kernel initialization. Designed and implemented a ZeroMQ based pub/sub messaging between the API configuration and the web page data generation and cache processes. Use PAM to unify authentication and authorization via SSH, web, or API by LDAP, Radius, TACACS+ or Kerberos remote authentication.• Feature upgrades to existing platforms. Implement remote logging through syslog-ng and a specific facility for custom audit logs. Re-architected 1-Wire driver code with a HAL layer to detect the existence of the new DS2485 or legacy DS2482 master off the i2C bus.

Coordinated with teams of Software Engineers on projects developing features that enhance security and traffic management for networking devices. Alternatively, work independently on complex projects, coordinating with cross-functional teams (Engineers & Vendors) to deliver firmware features and enhancements.EXOS Switching – Linux RTOS, fixed, modular and stackable switches• Developed ACL Style Policy based on IETF-netmod-acl-model allowing for rule lookups in user entered ACL order instead of being predefined by the rule type (hierarchical). It also supported 5-tuple rule match and decoupling forward/drop and CoS actions for improved use of hardware classification rules.  Implemented RESTCONF APIs for cloud management following YANG data models.  Created unit tests using ROBOT/Pycharm under GitHub source control.  Implemented new CLI using Python.  Worked with QA in India defining system tests and resolving issues.• Implemented IEEE 802.1AE MACsec with Pre Shared Key authentication (802.1X-2010). This allowed for port based NAC and point-to-point encryption.  Tied the secured/unsecured port states to the existing port operational state.  Integrated the send/receive EAPOL “hello” packets and MKPDUs with the state machine to control port operational state and programing of the PHYs (encrypt or clear).  Worked with Broadcom on SDK and PHY issues.  Updated platform YAML files to specify per port MACsec support.  Tested interoperability with Enterasys, Juniper and Linux MACsec implementations.

Matrix N/S/K/ToR-Series – VxWorks RTOS, Flow-Based Switch/Routers• These chassis were a fully distributed architecture where each application on every blade was responsible for its bootup, synchronization and data distribution.• Implemented IEEE 802.1AE MACsec with PSK authentication (802.1X-2010) using BSD licensed control layer (hostap).• Ported AP Aware/Authentication Override feature from EXOS to EOS so only the AP gets authenticated via 802.1X on the switch port and not the wireless clients.• Added support for Convergence-Endpoint (CEP) for assignment of policy rules to CDP and LLDP detected IP telephony devices, including support for CEP MIB and CLI.• Implemented AutoConfig/Zero-Touch-Provisioning which used DHCP and NetSight/SNMP to load the latest image and/or configuration onto an unconfigured/newly deployed system.• Revised nonvolatile (persistent) storage, bootup, cleanup and distribution across blades in the chassis. Upgraded bulk moves from FTP to NFS and distribution to TIPC socket.• Documented and implemented Netflow V9 support and verified with 3rd party collectors.• Evaluated and submitted recommendation for SSH vendor with VxWorks 6.5 support.• Implemented various CLI security configurations for Army JITC/TIC compliance.Matrix X-Series Core Router• Linux RTOS (Redhat) with a dedicated control plane that operated separately from the switching /routing data plane.• Extensive use of Linux simulation (UML) to expedite firmware development.• Implemented wrapper code for third-party and Open Source NTP, SSH client and server, DHCP client and DNS components to facilitate integration into platform firmware.• Implemented Netflow, flow based statistics and tested with 3rd party collectors.• Implemented RMON Statistics, History, Alarms, and Event MIB groups.• Implemented SMON port mirroring over a distributed architecture.• Ported VxWorks based Layer 2 components to Linux.

SSH • Ported 3rd party SSH client and server code to VxWorks.• Participated in definition of proprietary SSH Server MIB.• Assisted other platform groups in deploying SSH.Matrix E1• Member of team that developed and delivered the industry’s first 10 Gigabit Ethernet box.• Ported the Broadcom ASIC driver (BCM5632) into the E1 code base.• Worked closely with Broadcom engineers to resolve issues found in Beta driver code.• Ported Layer 2 code base from pSOS to VxWorks.Next Gen MMACPlus • Implemented Priority Queues based on IEEE 802.1p (traffic prioritization) and 802.1q (VLAN tagging). • Implemented Runtime Address Discovery (RAD) using BOOTP and RARP to support dynamic IP address acquisition.• Implemented Access Control List (ACL) to limit management access.Common Platform Services • Bundled core OS services and L2 features shared by over 10 platforms derived from a single object oriented code base to maximize code reuse and reduce development and test.• Developed APIs and COM functionality to support loading and unloading Dynamic Linked Libraries (DLL).
