EXPERIENCE
Variable, Inc., 06/2012 – Present

Senior Software Engineer, 2018–Present
- Rebuilt color search as a new Go service for Variable’s mobile apps and Variable Cloud, handling about 20,000 requests per day. Led the 2026 migration off the earlier Elasticsearch-based version, cutting average production response time from 7 s to 0.5 s.
  How: I helped build the first color search on Elasticsearch in 2016. By the time it was replaced it averaged about 7 seconds per request in production. I designed the Go rewrite and led the 2026 move of mobile and Variable Cloud traffic onto it. The average is now about half a second.
- Took Bridge by Variable from a B2B offering that needed technical integration on the corporate side to a commercially available, ready-to-use app, as technical lead and project manager. Completed in 2026.
- Replaced AWS Route 53 traffic policies and DNS-based routing with a Cloudflare Workers routing layer, designed and built for staging and production.
  How: Routing used to live in DNS records and Route 53 traffic policies. Moving it into a Workers layer means staging and production routing is now defined in code instead of DNS configuration.
- Wrote two dependency-free TypeScript SDKs (ESM + CJS): the color search client that defines the API contract for mobile and web, and the client for Bridge by Variable.
- Built the Go color library service for Variable Cloud and the mobile apps.
- Technical lead and architect on a four-person team of senior engineers. Turn product vision and strategic goals into technical plans and ship them, and work directly with partner and customer teams on integrations.

Software Developer, 2013–2018
- Built the first Go services in 2016: mobile data sync and color downloading, which grew into the content packaging service that turns customer product catalogs into mobile-ready offline databases on AWS S3. Helped build the original color search on Elasticsearch.
  How: Most of Variable’s users work primarily offline, so the download service is how most of them get color data: it turns a customer’s product catalog into a database the app keeps on the device. Search and sync cover what needs a connection.
- Built the central authentication and identity provider in 2017 that powers Variable services and applications. Lead maintainer since.
- Built the Android and Windows color sensor SDKs used by third-party corporate developers.
- Implemented Bluetooth Classic (2.1+) and Bluetooth Low Energy (4.1+, 5.0) connectivity for Variable’s color sensors, working from the hardware team’s designs to link each device feature to the app layer customers use.
- Developed Android (Java) apps including Color Muse, 2012 to 2020.

Android Developer Intern, 2012–2013
- Developed Android apps while completing a B.S. in Computer Science.

Earlier: Transcard (Database Intern, 2011 to 2012), Tricycle (Database and Reporting Specialist, 2010 to 2011).
