I am seeking a fun software engineering position with the constant opportunity for learning. My software development experience encompasses work I have done as a child, as a lifelong hobby, as classwork, as my work study job, at three internships, as consulting work, and finally as my full time job for my entire adult life.

I have created or maintained point of sale (POS); financial derivative trading/management; electronics computer aided design; automotive reverse engineering; system administration; domain registrar; kernel module; command-line utiltity; fantasy sports management; and game software.

In order of increasing familiarity, I have used the general-purpose programming languages BASIC, Fortran, C++, Pascal, Tcl, Java, JavaScript, Perl, C, and PHP. I will adapt to whatever toolkit is in use. My programming style reflects my preference for simplicity and long-term code maintainability.

I have a special interest in web services. For the past ten years, I have spent most of my time working on web services integrations, primarily JSON and SOAP. I enjoy instrumenting software, smashing bugs, and writing documentation.

Work Experience

Ann Arbor, MI
Software Engineer / System Administrator
March 2009 through March 2017

I maintained and extended a web services-based touch screen point of sale (POS)
system running on three stacks: Linux/Apache/MariaDB/PostgreSQL/PHP,
Linux/Apache/PostgreSQL/Oracle/Perl/PHP, and Linux/Apache/PostgreSQL/PHP.
Aside from a binary module implementing biometric authentication for Microsoft
POS Ready 2009, the entire NetPOS front end is pure JavaScript and uses
Mozilla's XUL and XBL toolkits. I removed our second-to-last binary module
dependency by porting receipt printing support to js-ctypes and I continued to
remove Windows dependencies until the front end ran successfully on Android
tablets (aside from receipt printing). During my tenure we implemented Agile
practices for our PCI PA-DSS certification. I wrote Chase Paymentech's first
NetConnect 1.0 SOAP API stored value integration. I designed a SOAP with WSDL
architecture for online ordering. I integrated to ProfitPoint's loyalty system.
I made numerous improvements to our Paytronix loyalty and stored value
integrations, converting the system to SOAP with WSDL. I wrote our First Data
ValueLink stored value integration, driving a complex certification process to
completion. We designed a JSON-RPC-based interface for CaptureCode's loyalty
system and I later extended this interface to include stored value and mobile
payments for Virtual Next, AppFront, and Relevant Mobile. I wrote our LevelUp
mobile payments integration. I added an interface to the HyperActive drive thru
interface (DTI) using XML with DTD validation. I implemented a SOAP interface
to Heartland stored value. I helped guide NetPOS through updates from CentOS 4
and CentOS 5 to CentOS 6 and then to CentOS 7 with 24/7 responsibility for
server and stack availability. I completed the migration of the NetPOS back end
software to Amazon Web Services (AWS). I added support to NetPOS for both IPv6
and HTTP/2. I was personally responsible for over one-thousand new features and
bug fixes added to NetPOS over an eight year, one month period. For this work
I was normally responsible for all or virtually all of the product lifecycle,
including gathering customer requirements; release planning; project planning
and creating time estimates; the software development itself; end-to-end
testing and quality assurance; and rolling out the new software to staging and
production environments.
