OBJECTIVE:

Senior software developer position in a collaborative team environment creating leading-edge solutions using Java, XML, and Internet technologies.

SUMMARY:

Detail-oriented, Master's-level software analyst/developer with 5 1/2 years of Java, focused on J2EE enterprise web applications, XML, and other Internet formats and protocols, backed by 10 years of C with 2 years of C++, in product development in the electronic design automation industry.

TECHNICAL SKILLS:

Other Tools: Rational Rose; WebLogic Server, Apache, Tomcat, JBuilder, Mercury LoadRunner

EDA/Hardware Description Languages: VHDL, Verilog; language specification, processing, and intermediate representation; event-driven simulation, code generation

EXPERIENCE:

Requirements Analysis and Business Object Modeling:

• Analyzed business requirements for security-trading tracking and accounting system.

  • Created UML business object model (Rational Rose plus hyperlinked textual description).
  • Documented system use cases.

Enterprise Application Integration (EAI) Product Development:

• Characterized legacy C/C++ version of application integration broker for re-development in Java:

  • Modeled existing system with UML use cases and object models.
  • Derived implied requirements.
  • Documented detailed behavior.
  • Prototyped multi-threaded triggering and control algorithms.

Web Applications, J2EE, WebLogic Server:

• Developed J2EE-based medical credentialing web application using servlets, JSPs, and EJBs. Reduced development effort by providing common functionality to other servlet developers:

  • Created HTML form/table generator.
  • Created servlet subclass hierarchy for common protection domains and page navigation.
  • Designed durable URL hierarchy and created dispatcher servlet.

• Reverse-engineered security realm provider interface for J2EE reference implementation. Reduced WebLogic development licensing costs by enabling development on reference implementation of applications targeted for deployment on WebLogic Server.

• Enhanced portability of commercial CRM product code from WebLogic Server by identifying code not compliant with J2EE specifications.

XML, XSLT:

• Demonstrated XSLT-based web interface to SOAP-based financial calculation server:

  • Constructed SOAP requests directly from HTML form data.
  • Mapped SOAP responses directly to HTML pages.
  • Resulted in follow-on contract.

• Developed in-house XML knowledge; provided XML consultation:

  • Attended XMLSolutions' XML course, XMLOne conference; monitored standardization efforts.
  • Explored, prototyped with XML parsing and XSLT transformation tools.
  • Developed and gave internal XML-orientation presentation.

• Created Netscape bookmarks indexer with XSLT (personal project):

  • Parsed HTML into XML; generated indexed HTML with XSLT stylesheet.

Corporate Development Environment and Methodology:

• Created cross-platform development area template for J2EE-based web application projects; reduced project startup time and cost:

  • Created Apache Ant build script; defined standard directory structure.
  • Supported WebLogic Server and incremental EJB deployment.
  • Supported J2EE reference implementation and EAR-file packaging.

• Contributed detailed coding standards; promoted JavaDoc linking features.

• Harvested code for re-use library.

GUI Development:

• Created document generator subsystem for commercial loan application. Allowed non-technical personnel to specify machine-generated documents:

  • Created WYSIWYG editor for document templates with conditional and data-insertion constructs.
  • Generated documents from templates plus loan data.
  • Created generic meta-data interface to connect to system.

Testing:

• Guided load testing of commercial document storage and indexing product using Mercury LoadRunner. Identified latent obfuscator problem and class loader interaction problem.

• Redesigned intermediate representation of VHDL hardware description language (HDL):

  • Increased capacity and reduced memory use by factor of 6.
  • Enabled speed increase by factor of 7.
  • Simplified use by client tools; added new language features.
  • Greatly reduced customers' conversion effort and risk by envisioning and creating emulation library to allow incremental conversion of old client code.
  • Created detailed conversion instructions; provided pre- and post-sales support.

• Designed intermediate representation of Verilog HDL. Documented with cross-linked HTML for easy cross-referencing.

• Developed GUI for VHDL formal verification tool using Galaxy C++.

• Architected and developed VHDL simulator construction kit product.

  • Designed simulation kernel interface.
  • Designed mapping from VHDL to C code calling kernel interface.
  • Created C code generator.
  • Created simulation kernel reference implementation.
  • Created interface and integration documentation.
  • Provided pre- and post-sales support.

• Architected and led team developing special-purpose object-oriented database system for storing compiled VHDL design descriptions:

  • Developed system API and internal data structures and algorithms.
  • Developed schema-language processor and C-code generator.
  • Wrote tool-integrator and end-user documentation.
  • Responsible for production and shipping of releases.
  • Provided pre- and post-sales support.

• Taught VHDL simulation language courses to end-user engineers.
