PROFESSIONAL EXPERIENCE:

Confidential, San José, California

Web Application Developer

Responsibilities:

• Installed development platform from scratch { Ant, Maven, Gradle, Spring Tool Suite, Java SE, Apache Tomcat, et cetera }.
• Designed and coded Tomcat Web application to perform telematics unit validation using Servlets with Spring Tool Suite, Postgres with JDBC, OkHttp, BarcodeJ, and GSON libraries. Features included:
• User authentication using MD5 hash.
• Successful validation created new bar code, with relevant information written to database.
• Global alert condition lockout on validation failure.
• Tomcat use of a privileged port using Apache forwarding.
• All code documented in JavaDoc and checked in to Git repository.
• Allows the user to set selected image as wallpaper for their device.
• Multi-threaded design uses all available cores.
• Wrote Digest Authentication override for OkHttp to access protected resources.
• AES-256 encryption of the Google Cloud Messaging registration identifier.
• Registration server written in D that maintains a database of registered clients via an HTTP POST operation that validates packets received.
• Java application implements the Google Cloud Messaging 'tickle' that reads this database to notify installed applications when new thumbnails are available.
• Backend to support the buttons on the 'detail screen' is written in D.
• Created a custom 'rainbow' spinner for a progress bar built using Hue-Saturation-Value colormap with a Gamma curve in Matlab.

Confidential

Responsibilities:

• Designing and developing code to analyze data and recommend algorithms involving the application of wavelets to detection and classification of the acoustics of Ziphiidae.
• Designing and developing code to analyze data and recommend algorithms for processing ambient noise in the ocean { id est ‘acoustic daylight’ }.
• Code was written in Matlab using the Signal Processing and Wavelet toolboxes, with functions written in Java, C, and D for post-processing, collation and presentation.
• Supporting tasks included segmentation of input waveforms, plotting and graphing of input data, edge-effect removal, hue-saturation-value colormap calculations based on various parameters of output data, coordinate transformations from cartesian to polar, assembly of time-series images for animations, and scaling of soundtracks to match the animations.
• Presenting publishable results in conference.
• Wrote a custom 48-bit imaging library to present results of the analysis.
• System administration and configuration of a 35TB data archive.
