Senior Programmer/Analyst2012 - 2015Alco Stores, Inc.
Technologies: XML, JSON, Microsoft SQL Server, Oracle, Python, Pyramid, CherryPy, Magento
- Designed our order dispatch system allowing stores to ship any store-based inventory items purchased from our eCommerce site. The system dispatched orders based on real-time inventory metrics, previous order load, and distance from the customer. If a store had to reject an order for any reason, it was logged and automatically delegated to the next logical location.
- Created an internal website with Pyramid that allowed buyers to manage the Magento/OMX system by keeping pricing and promotions in sync with spreadsheets (Buyers preferred using spreadsheets as a means of communication).
- Added validation of uploaded spreadsheets to allow buyers to verify the integrity of spreadsheets against Magento before attempting to upload edits or new items. This eliminated previously required back and forth with spreadsheets while developers verified integrity. It also allowed finer-grained checks as other issues were discovered.
- Provided the store support center with reporting to follow up on customer issues and any compliance questions.
- Tested ruthlessly and wrote concise documentation into the site to provide stores and our helpdesk guidance in the event of exceptions.
Senior Programmer/Analyst2010 - 2015Alco Stores, Inc.

- Wrote extensive testing and documentation around the customer loyalty project. I'm pleased to note that it ran without any issue for the lifetime of the deployment.
- Created a portal site to allow marketing to manage the creation and distribution of our email list through a PowerMTA system. We used this system to send over 3 million emails per week for several years.
- Managed the Apache site that provided the resource assets (images and PDFs) for the emails we sent.
- Provided reporting based on email opens and clicks to allow marketing to respond to customer trends.
Intranet Developer2008 - 2012Alco Stores, Inc.
- Integrated dual authentication allowing both store-based Tomax LDAP associates and Active Directory-based store support center clients to use the same portal. Directed authentication to the most likely system for auth based on login filters.
- Allowed authorization based on ldap auth source and MS SQL tables defining the hierarchy placement of the client.
- Wrote a custom CMS that allowed store support clients to continue working in a way that was familiar to them but allowed store-based clients access to documents previously unavailable to them.
- Wrote a task dispatch system that allowed departments to present tasks to stores and the store support center to view the tasks from a higher level determining compliance. It allowed multiple store groupings based on the authentication level of the user signed into the portal.
- Increased load capacity by running Zope server behind Apache and deferring all static files to the Apache server. Enhanced security by using SSL and certificates.

- Added the ability to accept EBT-based tenders, manufacturer coupons, store based coupons, and the tax algorithm edits necessary to maintain the integrity of the tender system. (We were in 18 states, each of which had unique tax requirements.).
- Wrote the bridge to allow both platforms to communicate with a Linux server placed into stores to manage perpetual inventory. Enabled all communication from the new Linux server to our general office through the existing legacy communication platform in the point-of-sale system.
- Wrote numerous utilities and created reporting to allow proactive management of systems instead of reacting to failures.
