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. I would describe myself as a Linux generalist with the ability to solve any programming problem that presents itself.

As an excerpt 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 utility; 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 have been programming exclusively on the Linux system since 1994 and on Red Hat Linux and its derivatives since 1996. I am comfortable with every aspect of the Linux environment, including shell scripting, system configuration, and troubleshooting.

My programming style reflects my preference for simplicity and long-term code maintainability. I immediately adapt to existing coding practices and learn whatever languages and libraries are currently in use. I enjoy fixing bugs and writing documentation. I am a stickler for software quality, because I often work on software involving financial transactions. It is my job as your programmer to make everyone else's job easier.

Work Experience

Auto Credit Express, Inc.
Auburn Hills, MI
Software Engineer
August 2017 through Present

Just getting started.


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.
