Professional Experience

Nester Hosiery         Mt Airy, NC

2011-Present VP Technology

Nester make socks for a wide range of retail stores, private labels, and outdoor brands at their factory in rural North Carolina. I was introduced to them as a consultant in 2005 and after many successful projects, they approached me to continue leading their modernization efforts.

Selected Accomplishments:

• Our company was selected as the pilot garment manufacturer for the Responsible Wool Standard because our high level of technology and data-driven manufacturing made it easy to provide a clear chain of custody from the receipt of certified wool to the dispatch of final socks to Patagonia.
• Holistically designed a system to move our business from an estimated-cost model to a true standard-cost model in accordance with GAAP. This included a component to streamline approval of costs on thousands of products as they exist in every step of the manufacturing process and to account for variances at month end.
• Assisted in preparing the company for sale to a private equity group by not only providing required tech diligence but also by interpreting our operational data and projections.
• Oversaw growth in several direct-to-consumer channels, including developing a new Amazon-specific brand and bringing it from zero to $500k of revenue in the first year.
• Managed the virtualization of our locally hosted servers onto Microsoft’s Hyper-V platform and developed disaster-recovery plans for our core IT infrastructure.
• Worked with our team on the factory floor to replace their time-honored ink-and-paper production system. Designed, built, and sold in a tablet application giving manufacturing real-time access to information. Its enthusiastic adoption led to measurable gains in manufacturing efficiency.
• Designed, developed, and implemented genetic algorithms to automate several labor-intensive factory scheduling positions which allowed us to scale up without increasing headcount.
• Championed integrating off-the-shelf software and services when they can be tightly paired with our proprietary ERP system. Includes deploying NuOrder for integration with our smaller B2B customers and Liaison’s EDI stack for communicating with our larger customers.
• Created a Slack bot that can answer basic questions about our data and proactively alert the team to potential problems.

WayIn         Denver, CO

2011 Technical Lead Engineer

WayIn were founded as a social media polling platform. The CTO recruited me to form and lead an engineering team. Together we developed the original prototype into a fast, scalable platform for our soft launch.  

Mobile Foundry        Boulder, CO

2005 – 2011 Independent Contractor/Principal Engineer

Mobile Foundry was a small software contractor who provided services to a broad range of small and mid-sized businesses. This was a great experience for me as I gained exposure to lots of different technologies and industries.

Selected Accomplishments:

• Built a Java application that ran on top of hundreds of servers at EC2 to evaluate different approaches to closing high schools and redistricting a county. We provided a solution to the school board which allowed them to close two unnecessary schools while balancing the remaining student population and reducing overall transit costs.
• Created a system for analyzing the effectiveness and reach of a store within their primary market area. This Java system loads each of the store's existing customers into a PostGIS database. The application then makes use of R to create a “Primary Market” shape. Experian and Census data is then used to identify what makes those customers unique and a custom mapping engine produces presentation­ quality pdf maps.
• Developed and maintained a custom ERP system for use in textile manufacturing. Using C# on a mix of desktop, web and on mobile terminals, this system handles all forecasting, supply chain, manufacturing, employee time tracking, shipping and invoicing for a US­-based manufacturer..
• Reverse-­engineered the data files behind the two market-leading mortgage origination products, and created an algorithm that was able to use the messy and incomplete data, current home­ value estimates and historic rates to project the outcome of complex variable rate and payment­ capped loans, ultimately identifying customers who could benefit from refinancing.
• Migrated an operational SMS ­based marketing service from a traditional hosting environment to a load­ balanced implementation on Amazon EC2. By only using a large amount of processing power during high volume marketing campaigns we were able to cut operational costs in half, while increasing flexibility and adding redundancy.
• Created a prototype of a geographically ­enabled dating site using JQuery and Java in under a month which was successfully used to attract further investment in the project.

Sun Microsystems         Linlithgow, Scotland / Broomfield, CO

2000 – 2005 Software Development Engineer

I started as an intern on the “SunStart” program and was given the chance to come to the United States for a year-long internship. After returning to finish my degree I transitioned into full-time employment and eventually made my way back to Colorado. I spent most of that time maintaining the SunSolve support site and helped migrate it to Java, and was awarded a US patent for my novel approach for continuing to authenticate legacy services during the transition.
