wyDay - LimeLM – Contributing developer on LimeLM, wyDay's software-licensing product, supporting multiple platforms (Windows/Linux/Mac) and programming languages (C++, Java, C#, etc).  Some highlights:

• Implemented modifications for a server (C++) to use a database (instead of a file) for persistent storage, and with support for multiple account instances (instead of just one).
  
• Created a reference application (Java GUI), client API, and server-side support for new functionality (C++).
• Implemented support for "seamless" upgrades of a server (C++), with no interruptions to client services.
• Implemented client and server-side support (C++, Java, C#) for two-factor authentication of logins into a server.
  
• Created and improved various tutorial/example programs (C++, Java, C#), with dynamic and static linking into product libraries.
  

 

CISN Display / QuakeWatch – Architect and primary developer of the CISN Display, the QuakeWatch server, and the QuakeWatch Information Distribution System (QWIDS).  The CISN Display provides real-time notifications of earthquake events on a GUI-map display, and was developed over a 10-year period under contract to Caltech/CISN and the USGS.  Written in Java, the CISN Display uses a client-server architecture to receive earthquake-event and product messages from seismic networks.  Features include configurable map layers, event alarms, notification of Tsunami-warning messages, and email alerts.

 

ShakeAlertToCAP – Developed software in Java that receives seismic-event messages from a USGS ShakeAlert server, converts them to the Common Alerting Protocol (CAP) XML format, and sends authenticated messages to FEMA-IPAWS servers.

 

Earthworm – Team developer, working on maintenance, development of new modules, and updates for 64-bit compatibility.   Earthworm is a suite of open architecture, open source software modules for seismic data acquisition, processing, archiving and distribution.  The modules, written in 'C', can run on Linux/UNIX, Windows and Solaris.  The Earthwork project is funded by the USGS.

 

JEvalResp / JPlotResp -- Principal developer - JEvalResp evaluates and processes response information from seismic instruments.  JPlotResp adds a GUI interface and plotting of output graphs.  Response information may be read from files or fetched from remote servers.  Written in Java and able to run on all major computer operating systems.

 

SeisNetWatch - SeisNetWatch server and GUI client.  SeisNetWatch provides state-of-health monitoring for seismic networks, with "reactor panel," map and detail views.  Written in Java, able to run on all major computer operating systems, SeisNetWatch uses client-server and collection-agent architectures to receive, process and display real-time status data from instruments and processes.

 

Rockhound Modules – Developed embedded software modules for Kinemetrics seismic-data-acquisition instruments.  The modules allow the instruments to be interfaced with the Earthworm, SeisComp, and SeisNetWatch software packages.

 

SeisComp – Developed a modification for the SeisComp3 SeedLink Server (written in C++) to detect (and reject) duplicate and "future" data packets, allowing proper processing of the packets downstream.

I enjoy interacting with and modifying the firmware used in UAV-drone flight controllers and other hardware.  I've contributed modifications to several open-source projects, and have posted utility programs, as described below.

 

• Developed the ArduVidRx Android app to operate an FPV video receiver that has been modified to have an Arduino Pro Mini add-on board.  (Also implemented the Arduino code and serial-interface protocol.)

 

• Created ‘IMDTabler’ and ‘FreqSetGen’, web-based tools in Java for calculating IMD (Intermodulation Distortion) effects on FPV video signals.

 

• Implemented modifications to the Delta 5 Race Timer, an open-source multi-node timing system (Raspberry Pi, Arduino, Python, Javascript, SQL).

 

• Implemented patches to the Betaflight controller firmware that enhance how a connected FPV video transmitter can be configured.  These patches have been merged into the Betaflight master code.

 

• Developed ‘clipytool’, a command-line utility written in Python for interacting with a Cleanflight controller board.
