Summary:

Used C and Java in the production of full stack software in Windows that command and monitor satellite subsystems. Wrote API’s to ensure software streams are clear to all network developers. Experience using Python writing user interface software to automatically build TCL spacecraft test scripts reading MySQL databases.

Used Golang, JSON and PostgreSQL to create a server reading test console data TCP streams to populate HTML web page and send data to a central server to be used to show an intra-net status page for all active spacecraft under test.

Controlled software releases via GIT, SVN, and Mercurial regulated by Bugzilla and Agile style meetings with peers.

Provided Intra-net status web page using Javascript, PHP, HTML, XML, and CSS using Apache Tomcat.

Experience with AmazonS3 cloud storage. Knowledge of RESTful API. Built and used CentOS, Ubuntu and Windows operating systems. Experience:
