Senior Technical Writer01/2004 to CurrentScalable Network TechnologiesLos Angeles, CA
Leading Documentation Team Managed other technical writers and worked with other team leads in the product development group to define the documentation requirements and release schedules.
Defined the scope, structure and content of the user documentation and created conforming contents templates.
These templates were used by the documentation team to ensure completeness, consistency and clarity across all documents.
All existing documentation was also converted to this new format.
Managed the development and timely delivery of multi-volume documentation in multiple formats for several (4-5) product releases every year.
Each release typically consisted of 4000-5000 pages of documentation.
User Documentation Creation Wrote and edited product documentation including Installation Guides, Product Tours, User's Guides, and Model Libraries for the company's suite of network simulation/emulation and cyber defense training software (including QualNet, EXata, Network Defense Trainer, and Joint Network Emulator).
Wrote Programmer's Guides and API Reference Guides for use by advanced users who wish to customize the software and develop their own models.
This required reading and understanding C and C++ code.
Applied my deep expertise in computer networks and simulation to understand the intricacies of the network simulation software, which was crucial for generating accurate, relevant and user-friendly documentation.
Created FrameMaker templates, style guides, and processes to improve the layout and to make the user documentation accurate, clear, and complete.
In addition to writing many new documents, revised a large volume of legacy documents to make them conform to the new templates and style guides, making the entire documentation suite complete, consistent, and more user-friendly.
Created single-sourced, conditional documents supporting multiple products and projects.
Designed and compiled PDF portfolios to integrate multiple files into a single, easy-to-navigate PDF file.
Developed HTML content for WebHelp and the database for GUI help using ePublisher and FrameMaker.
Editing Edited product data sheets and other marketing material.
Helped sales personal draft responses to customer queries about product features.
Edited successful SIBR and STTR proposals.
Edited enablement material used in SCALABLE's training classes and suggested improvements.
QA and Testing Enhanced company software products by conducting extensive testing of the product features and identifying many bugs and usability issues.
User Interface Enhancements Contributed to the design of GUI models of network components.
Identified various weaknesses in the UI and suggested improvements which were implemented.
Senior Engineer01/2001 to 01/2002Scalable Network TechnologiesLos Angeles, CA
High-level design of cellular network models which became part of Scalable's library of models.
Senior Engineer01/1996 to 01/2000Qualcomm, IncSan Diego, CA
Member of the Standards Group Participated in meetings of national and international cellular standard organizations: TIA TR45.5, 3GPP2 TSG-C, and ITU-T WP5.
Prepared and successfully presented articles in various standards groups, focusing on second third generation cellular networks.
These articles were incorporated in TIA's IS-95B, 3GPP2's cdma2000, and ITU-T's Q.1701 specifications.
Developed procedures for signaling (layer 3) and link layer (layer 2) of the CDMA air-interface, including radio resource control, mobility management, and connection management.
Optimized procedures for soft and hard handoff with return on failure for enhanced performance.
Message optimization and scheduling of configuration messages.
Inter-layer communication and modularization of the air-interface specification.
Prepared requirements for the LAC layer of the IMT-200 specification of ITU-T.
Senior Member of Technical Staff01/1993 to 01/1996Pacific Communication Sciences, IncSan Diego, CA
Modeling and Performance Evaluation of CDPD and pACT Systems: Developed detailed models for CDPD (Cellular Digital Packet Data standard's MAC (Multiple Access Protocol) and MDLP (Mobile Data Link Protocol) layers and applications such as FTP and telnet.
Evaluated system performance (throughput, capacity and delays) under a variety of coverage characteristics and workload patterns.
Identified errors in CDPD standards as a result of extensive modeling.
Derived value ranges for configurable parameters that optimize performance under different operating conditions.
Customizedmodels for specific customer operating scenarios and obtained performance data.
Modeled voice-traffic on AMPS to derive bounds for capacity available for CDPD use.
Application Engineer01/1991 to 01/1993Scientific and Engineering Software, IncAustin, TX
Designed and implemented reusable simulation models for communication protocols using SES/workbench.
Network protocols modeled include Ethernet, X.25 and SNA.
Served as consultant to SES customers for the modeling of client/server architectures for Management Information Systems.
Designed, wrote and presented seminars on techniques for modeling communication protocols to SES customers.
Developed successful proposals involving network models for potential SES customers.
