Richardson, TX 75082 Email: ******@*****.***

SOFTWARE ENGINEER

Dedicated, thorough and dependable Software Engineer with strong problem solving skills, strong web based software applications, and excellent telecommunication system knowledge (network monitoring switch, Carrier Ethernet, SONET, central office switch, wireless switching system). Strong emphasis on packet optical transport and SONET/Ethernet/OTN switch system. Expertise in Ethernet service OAM, equipment and facility protection switching, connection, provisioning, and performance monitoring software. Proven on time software delivery with low defect rate.

ACCOMPLISHMENTS

Designed and implemented software feature to allow the airline crew member’s schedule to be selectively exported to the TripCase application through REST API.

Instrumental in developing/working with FPGA and system test engineers to deliver Y.1731 PM and Ethernet Service OAM software (C/C++) features on multiple carrier Ethernet products (Linux and VxWorks based) in timely manner.

Achieved significant breakthrough by reducing protection switching time (<50 ms) on the SONET/SDH broadband cross-connects by conducting detailed analysis and optimizing existing C/C++ software.

Mentored and provided technical guidance to other software team engineers on the design and implementation of OC-48 1+1 APS and UPSR features.
