Ported most of the performance critical algorithms to C from Tilera assembly, originally developed in VHDL, which now run in a new architecture. Key to bringing development teams up to speed with the software components I did not personally portLaid the foundation for software teams to start feature development. Including the starting point for development of the “next generation” product line.Extended Tilera’s hypervisor to dynamically allocate and map variable length physical memory pagesDesigned and developed a way to "restart" crashed processes allowing the device to continue operation. This not only dramatically increased the product's up time but also aided in debugging issues which would have otherwise caused a customer network outage.Maintained and extended a suite of layer 7 protocol validation modules (sse, http, dns, ftp, snmp, asn1, ldap, ssh, ssl, smtp, mime, cifs …)

Maintained a full management net stack including arp, ip, tcp, udp, ssl, http, syslogDeveloped software drivers for Tilera’s peripheral xgbe/gbe packet ingress/egress hardwareDesigned and developed the switch policy module and drivers for the Marvell Dx130 and Dx8108Designed and developed the tri-speed and 10G network port (mac, phy, sfp) interfaces and drivers on 3 platforms each containing unique components accessed over different hardware “channels”. Chose an OOP approach for the network port configuration and monitoring module this allowed for easy integration of new components and platforms.Developed, maintained and ported software responsible for booting and monitoring Tilera platformsDeveloped a POST for a MPC8313 platform that verified correctness of the hardware and peripheral components i.e boot-flash, compact flash, i2c, spi, ram…Developed and debugged uart, i2c, spi, hpi, flash, usb, and tpm drivers on a MPC8313 some of which requiring the use of oscilloscopes for tuning signal qualityAssisted with the development of a secondary loader (post u-boot) for a MPC8313. Responsible for mapping memory regions, bringing the main program from flash into ram before starting a proprietary RTOS
